Maytag Washer Error Code d21/F27

The d21/F27 code means the washer detected an overflow condition. The overflow contact on the pressure switch stayed closed for more than 60 seconds, signaling that the water level reached an unsafe threshold and did not recover. This triggers a safety fault to prevent flooding.

It is not recommended to continue using the washer while this code is active. The fault indicates a potential uncontrolled water fill situation that could lead to flooding. Leave the washer unplugged until the cause is identified and corrected.

Repair costs depend on the failed component. A replacement water inlet valve typically runs in the range of $30 to $80 for the part, while a pressure switch generally costs between $20 and $60. If a control board is at fault, parts alone can range from $100 to $250 or more. Adding professional labor will increase the total cost depending on your area.

Start by clearing the error code, then unplug the washer and disconnect the electrical connectors from both the hot and cold water inlet valves. If water continues to flow into the tub after the connectors are removed, the inlet valve is mechanically stuck open and needs to be replaced. If water stops flowing, also inspect the pressure switch hose for kinks or blockages and test the pressure switch itself.

Clearing the error code may allow the washer to resume temporarily, but the code will return if the underlying problem is not fixed. If the inlet valve is mechanically faulty or the pressure switch is defective, a reset alone will not resolve the issue. Always diagnose the root cause before relying on a reset.
