Maytag Washer Error F21: What It Means & How to Fix It
Quick answer: F21 on a Maytag washer means the machine tried to drain and couldn’t clear the water within its expected window — the drain pump filter is clogged in the large majority of cases.
“Washer flashed F21 mid-cycle and wouldn’t drain. Igor opened the pump filter and pulled out a hair tie and a handful of change, showed me how to check it myself next time, no charge for the visit.”
Quick Answer
Maytag (and shared-platform Whirlpool) washers time how long draining takes. If water is still sitting in the tub after the allotted time, F21 trips as a long-drain fault. It’s a timing-based code, not a specific parts failure, which is exactly why the drain filter — the first thing restricting flow — is worth checking before anything else.
What Does F21 Mean?
Front-load Maytag washers have a coin trap / drain pump filter at the bottom front of the machine, behind a small access panel. Coins, buttons, hair ties and lint collect there over time, and once the filter is restricted enough, the pump can push water through fast enough to trip F21 even though nothing is actually broken.
4 Steps to Diagnose F21
Power off and locate the filter access panel.
It’s usually a small flip-down panel at the bottom-front of the machine, sometimes behind a decorative kick panel.
Place towels down and open the filter slowly.
There will be residual water in the trap — open it a quarter turn at a time to let it drain into towels rather than across your floor.
Clear debris and check the pump for obstructions.
Coins, small toys and buttons are the most common find. Spin the pump impeller by hand to confirm it’s not seized.
Have the drain pump tested if the filter was already clear.
An empty filter with F21 still showing points to a failing pump motor or a wiring fault — technician territory.
Can You Fix This Yourself?
Clearing the filter is designed to be a homeowner task — Maytag includes the access panel specifically for this. If the filter is clear and F21 keeps returning, you’re likely looking at the pump motor itself, which means partial disassembly best left to a technician.

Frequently Asked Questions
Is it safe to keep running loads with F21 showing?
The washer won’t complete a cycle with standing water inside, so it’ll stop itself — no real risk, just an unfinished load.
Will resetting the washer clear it for good?
Only temporarily if the filter is still clogged — the fault returns as soon as the next cycle needs to drain.
Is this an expensive repair?
Clearing the filter is free. A pump replacement is a moderate repair — your technician confirms cost after testing.
Can I clean the filter myself?
Yes — it’s designed for homeowner access. Just expect some spilled water and have towels ready.
