How to Fix F31 Error (Step-by-Step)

1. Press the cancel or stop button to end the current cycle and drain the excess water.
2. Unplug the washer from the power source and confirm the error stays cleared during a full test cycle.
3. Check the drain hose for any clogs or kinks that might be preventing proper drainage.
4. Locate and clean the drain pump filter, which is usually accessible through a small door on the front of the washer.
5. If the washer is still overfilling, the pressure switch, which senses the water level, may be malfunctioning.
6. To check the pressure switch, you will need to access it by removing a panel and inspect the hose for blockages and the switch for defects.
7. Turn the appliance off, wait about 2 minutes, then turn it back on.
