Maytag washer error code f20

Maytag is a reputable brand in the home appliance industry, renowned for its product longevity and quality performance. However, like any other machine, it is not immune to occasional hiccups. One such hiccup that many users experience is the F20 error code in Maytag washers.

Error codes serve as an integral aspect of self-diagnostic systems present in modern appliances. They provide users with insights into the nature of the problem and guide towards effective solutions. The F20 error code signifies a water-related issue in Maytag washers – either the machine is unable to detect water or is detecting an insufficient water supply.

Why the F20 Error Occurs

A Maytag washer displays the F20 error code when the water level sensor doesn’t detect any water coming in or if the water input is less than what’s required for the wash cycle to operate correctly. Multiple factors can trigger this error, including problems with the water supply, blockage in the hose, faulty water inlet valve, or an issue with the control unit.

Troubleshooting the F20 Error

Before diving into troubleshooting, it’s advisable to perform a simple test – disconnect the machine from the power outlet, wait for about 10 minutes, then reconnect it. This basic reset often fixes minor software glitches, which might be causing the error. If the error persists, it’s time to investigate more systematically.

  1. Water Supply

The first factor to investigate when dealing with an F20 error code is the water supply. Check the water pressure from your taps. If the pressure is too low, it could impede the water flow into the washer. Also, make sure the taps are fully open.

  1. Inlet Hoses

The next step is to examine the inlet hoses. Any kinks or blockages can obstruct water flow, causing the F20 error. Disconnect the hoses and flush them out to ensure they’re clear of any debris. After this, reconnect the hoses securely and check the washers inside the hose fittings to ensure they are intact and correctly placed.

  1. Water Inlet Valve

The water inlet valve regulates the amount of water that enters the washer. If it’s faulty, it can prevent the correct amount of water from entering the machine. You can check the valve’s operation using a multimeter. If the readings indicate a malfunction, replace the water inlet valve.

  1. Control Unit

Finally, if all the above components are functioning correctly, the error might stem from the control unit. The unit houses the pressure switch, which monitors the water level in the machine. If the control unit or the pressure switch is faulty, it might fail to sense the correct water level, triggering an F20 error. In such a scenario, it’s best to call in a professional technician as it requires specialized knowledge and tools to handle.


Despite its sophistication and reliable performance, a Maytag washer can occasionally display error codes that require user intervention. The F20 error code points towards a water supply issue, which can usually be resolved through a step-by-step troubleshooting process. However, if the error persists despite these steps, professional help should be sought. As with any mechanical problem, ignoring the issue or applying incorrect fixes could escalate the problem and even damage the machine irreparably.

Remember, understanding the meaning behind error codes not only aids in quick problem resolution but also empowers users with knowledge to prevent potential issues in the future. Regular maintenance and promptly addressing error codes can significantly enhance your Maytag washer’s lifespan and performance.
