Understanding the F21 Error Code

The F21 error code on your Whirlpool washer is an indication that there is a drain issue. This error typically occurs when your washer is unable to drain water properly during a wash cycle. It can be caused by various factors, and it’s essential to pinpoint the exact problem to resolve it effectively.

Reasons Behind the F21 Error Code

1. Clogged Drain Filter: One of the most common reasons for the F21 error is a clogged drain filter. Over time, lint, debris, and small objects can accumulate in the filter, obstructing water flow. This prevents the washer from draining efficiently.
