Whirlpool dishwasher troubleshooting

The make of Whirlpool is present in the market from the 1950 when as a result of a merger of American company Upton Machine with Nineteen Hundred Washer Corporation Whirlpool was born. Since those times, Whirlpool turned into the largest international holding company for production of household appliances, inter alia, of dishwashers.
The positions of Whirlpool in Europe are particularly strong – it is considered the third biggest company in its segment.
Wherever Whirlpool would work, everywhere it is seeking to establish Whirlpool’s high standards of quality, of reliability and of practicality.
Its high-energy efficiency characteristics are the difference of Whirlpool appliances, for which it was marked by many rewards.
The whirlpool dishwasher troubleshooting system allowing to determine a type of breakdown by error codes and remove malfunction is the advantage of dishwashers from Whirlpool. You can learn the details below.

If something should go wrong with your Whirlpool dishwasher, we suggest consulting the table below for quick and easy troubleshooting tips. It is designed to help you tackle the most common issues before consulting a servicer. The table can be used for the following series: WDF, DU, W, GU, WDT, 4, and 8.

PROBLEMCAUSESUGGESTED ACTION
Dishwasher is not operating properly1. Dishwasher does not run or stops during a cycle

2. The Clean light is flashing
3. Dishwasher will not fill
4. Dishwasher seems to run too long






5. Water remains in the dishwasher
6. Detergent remains in the covered section of the dispenser
7. White residue on the front of the access panel
8. Odor in the dishwasher
9. Condensation on the kitchen counter (built-in models)
1. Is the door closed tightly and latched? Is the right cycle selected? Is there power to the dishwasher? Has a household fuse blown, or has a circuit breaker tripped? Replace the fuse or reset the circuit breaker. If the problem continues, call an electrician. Has the motor stopped due to an overload? The motor automatically resets itself within a few minutes. If it does not restart, call for service. Is the water shutoff valve (if installed) turned on? It is normal for certain cycles to repeatedly pause for several seconds during the main wash.
2. Call for service.

3. Is the overfill protection float able to move up and down freely? Press down to release.

4. The dishwasher can run up to 3'/2 hours depending on soil level, water temperature, cycles and options. Is the water supplied to the dishwasher hot enough? The dishwasher runs longer while heating water. Is the dishwasher cycle time within the cycle times? See cycle sections wash times. A delay automatically occurs in some wash and rinse cycles until the water reaches the proper temperature. This dishwasher is equipped with an optical sensor wash that detects water temperature, soil and detergent amount. Wash cycles are adjusted based on what is sensed.
IMPORTANT: The very first wash cycle after installation in your home will be adjusted to include an additional 2 rinses. This cycle must not be interrupted for proper sensor adjustment. If
this adjustment cycle is canceled or stopped before the Clean light comes on at the end of the cycle, the next wash cycle will repeat this sensor adjustment.
5. Is the cycle complete?

6. Is the cycle complete? Is the detergent lump-free? Replace detergent if necessary. Is the dispenser door blocked by dishes or cookware when the dishwasher door is closed?


7. Was too much detergent used? Is the brand of detergent making excess foam? Try a different brand to reduce foaming and eliminate buildup.

8. Are dishes washed only every 2 or 3 days? Run a rinse cycle once or twice a day until you have a full load. Does the dishwasher have a new plastic smell? Run a vinegar rinse as described in “Dishwasher Care.”
9. Is the dishwasher aligned with the countertop? Moisture from the vent in the dishwasher console can form on the counter. Refer to the Installation Instructions for more information.
Dishes do not dry completely1. Dishes do not dry completely
2. Dishes are not dry

3. Excess moisture on racks and dishwasher interior
1. Did you use a rinse aid? Your dishwasher is designed to use rinse aid for good drying performance. Without rinse aid your dishes and dishwasher interior will have excessive moisture. The heat dry option will not perform as well without rinse aid.
2. Did you load your dishwasher to allow proper water drainage? Do not overload. Use a liquid rinse aid to speed drying. Are the plastics wet? Plastics often need towel drying. Is the rinse aid dispenser empty? Did you use an air-dry or energy-saving dry option? Use a heated drying option for dryer dishes.
3. Check the rinse aid indicator to see that there is rinse aid in the dispenser.
Spots and stains on dishes1. Spotting and filming on dishes









2. Silica film or etching (silica film is a milky, rainbow-colored deposit; etching is a cloudy film)
3. White spots on cookware with nonstick finish
4. Brown stains on dishes and dishwasher interior
5. Black or gray marks on dishes
6. Orange stains on plastic dishes or dishwasher interior
1. Is your water hard, or is there a high mineral content in your water? Conditioning the final rinse water with a liquid rinse aid helps eliminate spotting and filming. Keep the rinse aid dispenser filled. Always use a high-temp option. If your water hardness is 13 grains or above, it is strongly recommended that you install a home water softener. If you do not wish to drink softened water, have the softener installed onto your hot water supply.
Is the water temperature too low? For best dishwashing results, water should be 120°F (49°C) as it enters the dishwasher. Did you use the correct amount of effective detergent? Use recommended dishwasher detergents only. Do not use less than 1 tbs (15 g) per load. Detergent must be fresh to be effective. Heavy soil and/or hard water generally require extra detergent. Is the home water pressure high enough for proper dishwasher filling? Home water pressure should be 20 to 120 psi (138 to 828 kPa) for proper dishwasher fill. If you have questions about your water pressure, call a licensed, qualified plumber.
NOTE: To remove spots and film from glassware, remove all silverware and metal items and run a vinegar rinse as described in “Dishwasher Care.”
2. Sometimes there is a water/chemical reaction with certain types of glassware. This is usually caused by some combination of soft or softened water, alkaline washing solutions, insufficient rinsing, overloading the dishwasher, and the heat of drying. It might not be possible to avoid the problem, except by hand washing. To slow this process use a minimum amount of detergent but
not less than 1 tbs (15 g) per load. Use a liquid rinse aid and underload the dishwasher to allow thorough rinsing. Silica film and etching are permanent and cannot be removed. Do not use heated drying.

3. Has the dishwasher detergent removed cookware seasoning? Reseason cookware after washing it in the dishwasher.


4. Does your water have high iron content? Rewash dishes using 1 -3 tsp (5-15 mL) of citric acid crystals added to the covered section of the detergent dispenser. Do not use detergent. Follow with a Normal wash cycle with detergent. If treatment is needed more often than every other month, the installation of an iron removal unit is suggested.

5. Are aluminum items rubbing dishes during washing? Disposable aluminum items can break down in the dishwasher and cause marking. Hand wash these items. Remove aluminum markings by using a mild abrasive cleaner.
6. Are large amounts of tomato-based foods on dishes placed in the dishwasher? It may be necessary to use a stain removal product to remove stains from your dishwasher. Stains will not affect dishwasher performance.
NoisesGrinding, grating, crunching or buzzing soundsA hard object has entered the wash module (on some models). When the object is ground up, the sound should stop. If the noise persists after a complete cycle, call for service.
Dishes are not completely cleanFood soil left on the dishesIs the dishwasher loaded correctly? Did you choose the cycle that describes the most difficult soil in your dishwasher? If you have some items with heavier soils, use a heavier cycle.
Is the water temperature too low? For best dishwashing results, water should be 120°F (49°C) as it enters the dishwasher.
Did you use the correct amount of fresh detergent? Use recommended dishwasher detergents only. Do not use less than 1 tbs (15 g) per load. Detergent must be fresh to be effective. Heavy soil and/or hard water generally require extra detergent.
Is detergent caked in dispenser? Use fresh detergent only. Do not allow detergent to sit for several hours in a wet dispenser. Clean dispenser when caked detergent is present. Is the pump or spray arm clogged by labels from bottles and cans?
Is the home water pressure high enough for proper dishwasher filling? Home water pressure should be 20 to 120 psi (138 to 828 kPa) for proper dishwasher fill. If you have questions about your water pressure, call a licensed, qualified plumber.
Are high suds slowing the wash arm? Do not use soap or laundry detergents. Use recommended dishwasher detergents only.
Dishes are damaged during a cycleChipping of dishesDid you load the dishwasher properly? Load the dishes and glasses so they are stable and do not strike together from washing action. Minimize chipping by moving the rack in and out slowly.
NOTE: Antiques, feather-edged crystal, and similar types of china and glassware might be too delicate for automatic dishwashing. Wash by hand.

— Remove labels before washing or wash by hand. See page 15. Clean filter screen. See page 17.



— Home water pressure should be 20 to 120 pounds per square inch (psi) for proper dishwasher fill. A booster pump on the water supply may be necessary if pressure is too low.

— Never use soap or laundry detergents. Use recommended dishwasher detergents only.
Spotting and filming
— Hard water or high mineral content in water
— Water temperature too low
— Use of incorrect detergents
— Use rinse agent to help prevent spotting and filming. See page 11. To remove hard water film, see “Removing spots and film” on page 21.

— If needed, turn home water heater up to ensure water entering dishwasher is 120°F (49°C) minimum. See "To check water temperature” on page 18.
— Use recommended dishwasher detergents only.
Spotting and filming (continued)
— Incorrect amount of detergent
— Use of ineffective detergents
— Insufficient fill due to low water pressure
— Follow recommendations on page 10 for amount. Heavy soil and/or hard water generally require extra detergent.

— Use fresh detergent. Store detergent tightly closed in a cool, dry place. Discard lumpy detergent

— Home water pressure should be 20 to 120 psi for proper dishwasher fill. A booster pump on the water supply may be necessary if pressure is too low.
Dishes do not dry completely
— Dishes do not drain properly
— Plastics
— Dishes must have proper water drainage. Do not overload. Follow instructions for loading dishwasher on pages 7-9. Use a liquid rinse agent to speed draining.
— Some plastics, due to material, may need to be towel dried.
Silica film or etching (silica film is a white iridescent deposit; etching is a cloudy film)
— Water chemical reaction with certain types of glassware usually caused by
some combination of soft or softened water, alkaline washing
solutions, insufficient rinsing, overloading the dishwasher, and heat
of drying.
— It may not be possible to prevent problem, except by hand washing. To slow this
process, use a minimum amount of detergent but not less than one tablespoon per
load. Use a liquid rinse agent and underload the dishwasher to allow thorough rinsing.
Silica film and etching are permanent and cannot be removed. Use the ENERGY SAVER DRY option.
Black or gray иmarks on dishes
— Aluminum Hems touching dishes
— Load aluminum items so that they will not rub against dishes during washing. Do not wash throwaway aluminum items in the dishwasher because they may break down
and cause marking. Remove aluminum markings by using a mild abrasive cleanser.
White spots on cookware with non-stick finish
— Seasoning removed by dishwasher detergents
— Reseason cookware after dishwasher washing.
Brown stains on dishes and dishwasher interior
High iron content in water supply
Remove by washing dishes (after food soil has been removed) with 1 teaspoon to 1 tablespoon of citric acid crystals added to covered section of detergent dispenser. Do not use detergent. Follow with a LIGHT WASH cycle and detergent. (For models with one wash cycle, use WASH.) If treatment is needed more often than every other month, we recommend installation of an iron removal unit.
Orange stains on dishwasher interior
Large amounts of tomato based foods on dishes placed in the dishwasher
Stains will not affect dishwasher performance and can gradually fade over time. Regular use of RINSE & HOLD (on some models) reduces the chance of staining. If air in the dishwasher is heated during the Mdry" portion of the cycle, stains may fade slower than if the ENERGY SAVER DRY option is selected.
Odor in the dishwasher
Dishes only washed every two to three days
Run a RINSE & HOLD (on some models) cycle at least once or twice a day until a full load is accumulated.
Chipping of dishes
Improper loadingLoad dishes and glasses so they are stable and do not strike together from washing action. Moving racks in and out slowly will also minimize chipping.
NOTE: Some types of china and glassware are too delicate for automatic dishwashing and should be hand washed; for example: antiques, feather-edged crystal, and similar items.

Flash Start LED invalid if it is pressed and no door opening or power loss has
been detected since the last cycle.
If error is stored and customer cannot run a cycle, replace the door switch
61No WaterWater is not present in the machine when it should be. The most common causes of this are if the water line is disconnected or turned off or if the drain line set up is causing siphoning.
Two methods to detect depending on the model's water indicator:
1) Wash motor current sensing indicates no water or
2) OWI foam input indicates no water
Check for presence of water during fills and/or throughout heated wash intervals depending on model characteristics (see detailed failure table). Control shall wait for debounce time (defined in APL) before ending cycle due to this error.
Default debounce time is 30s.
If no water is present turn off the heater immediately when the “No water” condition is detected with the VWI or OWI.
1. Check if water tap is not closed.
2. Check if filter is not blocked.
3. Check if water line is not blocked (water is present in water connection)
4. Check if water is filling to the machine
5. Check if drain line set up is not causing siphoning: a) drain hose is too low; b) sewerage causes water gravitation siphoning
6. If machine is supplied with OWI - then clean it, run any customer cycle; If issue is not solved - replace OWI
62No Water (Fill Valve Problem)
Current sensing circuit does not detect current flowing to the fill valve during filling intervals. This could be caused by a faulty control, fill valve, or wiring.
Current sensing circuit does not detect current flowing to the fill valve during filling intervals.
Check 10s after the start of all filling intervals.
none1. Check connection: Fill valve <-> harness <-> Control Board
2. Check if valve is supplied (from board) or Check with differnt control board
3. Replace the fill valve
63Low water /
Suds
This error occurs when suds or a low water condition cause surging in the wash pump. Several things could cause this to happen, including excessive detergent or rinse aid in the water, dishware collecting water during the cycle, slow siphoning, or low fill amounts on units without a flow meter.Motor won't stop surgingCheck for surging during any wash interval in customer cycles.Before recording the error, wash pahse will be repeated. Turn off heater when surging is first detected. Add water when surging is detected. If water has been added to the maximum fill level possible and surging has not stopped, fully drain, refill, and restart the cycle phase. If surging continues and water has been added to the maximum fill level possible again, then the error is recorded and cycle ended with error.1. A Pot placed upside-down may collect the water
2. Hand wash dish detergent or some tablets may create very high foam
3. Leakage - water goes to dip tray, then overfills to the floor
64Overfill / Float switch actuatedSome models have a float assembly below the unit to detect if water from the tub has overflowed into the dip tray below. This error occurs if the float switch is tripped when the control is monitoring for a possible overfill situation.Overfill/float switch input opens, indicating a leak or too much water in the tub. Monitor this input
anytime the pilot
relay is on (door
must be closed).
none1. Check if water is collected on the diptray. If yes - find a leakage
2. If no water is present, check if the switch is activated mechanicaly
65Fill Valve Stuck OnFlow meter pulses are detected when the fill valve is turned off.When fill valve is off, flow meter reading shows > 17 pulses/1 Os.Check any time
machine is powered
and fill valve is
supposed to be off.
When error is detected, perform drain sequence (drain motor ON for 30s. then OFF for 30s) until flow meter pulses are no longer detected. This sequenceshall always end after a 30s drain period, regardless of when the flow meter pulses stop being detected. Note: This state must be saved to memory so the control can resume the drain sequence after a full power loss.Check if fill valve is mechanicaly stucked on - replace if needed
67Flow meter failure (flow meter models only)Flow meter does not generate pulses during filling intervals, but water is entering the machine. This could be caused by a faulty flow meter, control, or wiring.Flow meter does not generate pulses during filling intervals and current sense circuit indicates that fill valve is turning on.Detect during fill intervals.none1. Check connection: Flow meter <-> harness <-> control board

Whirlpool Architect II series, KUD series dishwasher troubleshooting

The Architect II C Series of Whirlpool dishwashers (including the KUD lineup) is comprised of convenient undercounter models. The table below may help you to resolve the issue your dishwasher is experiencing even if you are not competent in diagnostic routines.

PROBLEMSOLUTION
Dishwasher does not runNOTE: It is normal for the dishwasher to repeatedly pause several times during a cycle. If the Start/Resume light is blinking, close the door and push START/RESUME. Be sure the door is closed and latched. Check that there is not an interference with large casserole dishes and the wash system at the back of the dishwasher. Adjust loading as necessary to ensure door is closed and latched. Be sure you have selected a cycle. (See “Cycles and Options Descriptions” section.) Be sure there is power to the dishwasher. A circuit breaker or fuse may have tripped. If lights other than Start/Resume blink and the unit will not run, you will need to call for service.
Detergent remains in the dispenser or tablet is on bottom of tubCheck for dishware such as cookie sheets, cutting boards, or large containers, etc., that may be blocking the detergent dispenser from opening properly. Be sure your detergent is fresh and lump free. Be sure the cycle has completed (the Clean light is on). If it has not completed, you will need to resume the cycle by closing the door and pressing START/RESUME.
Cycle runs too longNOTES:
- To use less water and reduce energy consumption you will encounter cycles that typically run for up to 3 hours.
- A water heater setting of 120°F (49°C) is best, the dishwasher will delay longer while heating cooler water.
- Some options will add time to the cycle. (See “Cycles and Options Descriptions” section.)
The Heat Dry option adds approximately V2 hour. Try the 1 Hour Wash cycle. Run the hot water at a faucet close to the dishwasher before starting the cycle.
Dishwasher not dryingNOTE: Plastic and items with nonstick surfaces are difficult to dry because they have a porous surface which tends to collect water droplets. Towel drying may be necessary. Use of rinse aid along with the Heat Dry option is needed for proper drying. Proper loading of items can affect drying. (See specific loading instructions within this guide.) Glasses and cups with concave bottoms hold water. This water may spill onto other items when unloading. Unload the bottom rack first. Locate these items on the more slanted side of the rack for improved results.
Will not fillBe sure the water is turned on to the dishwasher. Check that the float is free from obstructions. (See “Parts and Features.”) Check for suds in the dishwasher. If foam or suds are detected, the dishwasher may not operate properly or may not fill with water. (See “BLINKING LIGHTS” in “Troubleshooting.”)
Water remains in the tub/will not drainBe sure the cycle has completed (the Clean light is on). If it has not, you will need to resume the cycle by closing the door and pressing START/RESUME. If dishwasher is connected to a food waste disposer, be sure the knockout plug has been removed from the disposer inlet. Check for kinks in the drain hose. Check for food obstructions in the drain or disposer. Check your house fuse or circuit breaker.
Hard water (white residue on dishwasher interior or glassware)NOTE: Extremely hard water mineral deposits can cause damage to your dishwasher and make it difficult to achieve good cleaning. A water softener is strongly recommended if your hardness is 15 grains or more. If a water softener is not installed, the following steps may help: Use a commercial cleaner designed for dishwashers once per month. Always use a rinse aid. Always use a high-quality, fresh detergent. Use a detergent booster/water softener additive designed for dishwashers.
OdorsNOTE: If the dishwasher is not used daily, you can run a rinse cycle with the partial load daily until a full load is ready to run, or use the Top Rack Only option (on some models) for partial loads. Run a vinegar rinse through the dishwasher by putting 2 cups (500 mL) of white vinegar in an upright glass measuring cup in the lower rack. Run a normal cycle with the Heat Dry option turned off. Do not use detergent. The dishwasher may not be draining properly, see “WATER REMAINS IN THE TUB/WILL NOT DRAIN” in “Troubleshooting.”
NoisyNOTES:
1. Surging sounds can occur periodically throughout the cycle while the dishwasher is draining.
2. Normal water valve hissing may be heard periodically.
3. A normal snap sound may be heard when the detergent dispenser opens during the cycle and when the door is opened at the end of the cycle.
4. Improper installation will affect noise levels. A thumping sound may be heard if items extend beyond the racks and interfere with the wash arms. Readjust the dishware and resume the cycle.
Food soils remain on dishesBe sure the dishwasher is loaded correctly. Improper loading can greatly decrease the washing performance (see Dishwasher Use”). Select the proper cycle and option for the type of soils. The Heavy Duty cycle with the ProScrub. (on some models) option can be used for tougher loads. Be sure the incoming water temperature is at least 120°F (49°C). Use the proper amount of fresh detergent. More detergent is needed for heavier-soiled loads and hard water conditions. Scrape food from dishes prior to loading (do not prerinse).
Dishes dirty/suds in dishwasher/cycle not completeIf foam or suds are detected by the dishwasher sensing system, the dishwasher may not operate properly or may not fill with water. Suds can come from:
1. Using the incorrect type of detergent, such as dish detergent for hand washing dishes, laundry detergent, or hand soap.
2. Not replacing the rinse aid dispenser cap after filling (or refilling) the rinse aid.
3. Using an excessive amount of dishwasher detergent. Call for service. If no water was present in the machine at any time during a heated wash cycle, the cycle will end and the Clean LED will not come on. See “Will Not Fill” in “Troubleshooting.”
Did not sanitizeIf the sanitized light is blinking, the load is NOT sanitized. The cycle was interrupted in the final rinse, or the temperature for your water heater is set too low. Set your water heater to 120°F (49°C).
Damage to dishwareImproper loading can cause dishes to become chipped or damaged. (See specific loading instructions within this guide.)
Blinking lightsBlinking LED's will occur when the cycle is paused or when the cycle has been interrupted by opening the door. In this case, the Start/Resume button LED, the Cycle Status Indicator LED(s), and the countdown bars on the Cycle Status Display all blink together to indicate that attention is needed. See Start or Resume a Cycle in the “Dishwasher Use” section. Blinking LED's can also occur when certain errors have been detected. In this case,the Clean/ Complete LED will blink one time with a pause in between blinks. Call for service.
Cloudy or spotted dishware (and hard water solution)NOTES:
1. Liquid rinse aid is necessary for drying and to reduce spotting.
2. Use the correct amount of detergent. Confirm that the cloudiness is removable by soaking the item in white vinegar for 5 minutes. If the cloudiness disappears, it is due to hard water. Adjust the amount of detergent and rinse aid. (See “HARD WATER [WHITE RESIDUE ON DISHWASHER INTERIOR OR GLASSWARE] in “Troubleshooting.”) If it does not come clear, it is due to etching (see below). Be sure the incoming water temperature is set at 120°F (49°C). Try using the High Temp and Sani Rinse options. To remove spotting, run a vinegar rinse through the dishwasher.
- Wash and rinse the affected dishware and load into dishwasher. Remove all silverware and metal items. Put 2 cups (500 mL) of white vinegar in a glass measuring cup in the lower rack. Run a normal cycle with the Heat Dry option turned off. No detergent is needed.
Etching (permanent cloudiness)This is an erosion of the surface of the glassware and can be caused by a combination of: water that is too hot, from using too much detergent with soft water or by pre-washing. Detergent needs food soil to act upon. If etching has occurred, the glassware is permanently damaged. To avoid further etching, adjust the detergent amount to match the water hardness, stop pre-washing, and use water heating options only when incoming water temperature is below 120CF (49°C).
Leaking waterBe sure dishwasher has been installed properly and is level. Suds can cause the dishwasher to overflow. Measure the detergent accurately and use only detergents designed for use in a dishwasher. Less detergent is needed in soft water. Try another brand of detergent if sudsing continues. To avoid rinse aid leaking from the dispenser, be sure the lid is securely attached and avoid overfilling.
Tub is discoloredNOTES:
1. High iron content in the water can discolor the tub.
2. Tomato-based foods can discolor the tub or dishware.
A citrus-based cleaner can be used to clean.
