Kitchenaid dishwasher troubleshooting

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.
Be sure you have disabled Sleep Mode by pressing either START/RESUME or CANCEL, or opening and closing the door before selecting your cycle/option.
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 “Cycle and Option 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 “Cycle and Option Descriptions” section.) The ProDry™ or Heat Dry option adds approximately ??? hour.
Try the Express 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 ProDry™ or 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” section.)
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.
Clean the upper and lower filters at least once per month. (See “Cleaning Instructions” in the “Filtration System” section.)
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 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 the “Troubleshooting” section.
NOISYNOTES:
- Surging sounds can occur periodically throughout the cycle while the dishwasher is draining.
- Normal water valve hissing may be heard periodically.
- 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.
- Improper installation will affect noise levels.
Be sure the filters are properly installed.
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” section).
Check filter to ensure it is properly installed. Clean it if needed. (See “Cleaning Instructions” in the “Filtration System” section for details.)
Select the proper cycle and option for the type of soils. The ProWash™ or the Tough 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).
SANITIZED LIGHT BLINKINGIf 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 DISHWARE Improper 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 4 times in a row with a pause in between each set of blinks. When this error occurs, the controls will lock out and not allow another cycle to be started.
Call for service.
CLOUDY OR SPOTTED DISHWARE (AND HARD WATER SOLUTION)NOTES:
- Liquid rinse aid is necessary for drying and to reduce spotting.
- 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 the “Troubleshooting” section. 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 120°F (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:
- High iron content in the water can discolor the tub.
- Tomato-based foods can discolor the tub or dishware.
- A citrus-based cleaner can be used to clean.
