What are the common reasons for the F21 error code on a Maytag front loader washer, and what steps can be taken to resolve it?

A drain or pump obstruction can contribute to the F21 error code on a Maytag front loader washer because it prevents the machine from draining water properly. This can lead to an accumulation of water in the washer drum, causing it to stop the cycle and display the error code.

To clear a drain or pump obstruction and restore proper drainage, you can follow these steps:

1. Unplug the washer and turn off the water supply to the machine.
2. Remove any clothing or items from the washer.
3. Locate the drain pump filter at the bottom front of the machine. The filter is typically behind a panel that can be removed by loosening a few screws or releasing a latch.
4. Place a towel or shallow dish underneath the filter to catch any water that may spill out.
5. Twist the filter counterclockwise and pull it out. The filter may be clogged with lint, debris, or small objects such as coins or hairpins.
6. Clean the filter by rinsing it with water or using a soft brush to remove any buildup. Be sure to remove any obstructions.
7. Reinstall the filter by twisting it clockwise and securing it in place.
8. Replace the front panel and secure it with the screws or latch.
9. Plug the washer back in and turn on the water supply.
10. Run a test cycle to ensure the machine is draining properly and the error code has been cleared.

If the obstruction cannot be cleared by cleaning the drain pump filter, there may be a larger blockage in the drain hose or a malfunctioning drain pump. In these cases, it may be necessary to call a qualified technician to diagnose and repair the issue.
