Kenmore washer F21 error code

Kenmore washer F21 means the drain cycle exceeded its time limit — water is leaving too slowly or not at all. Front-load Kenmore washers share this code with Whirlpool-platform models. The pump filter (coin trap) and drain hose routing cause most F21 errors; the drain pump itself fails less often on machines under ten years old.

How to fix F21

  1. Unplug the washer and locate the pump filter behind the lower front panel — place towels under the access door.
  2. Drain into a pan, remove the filter, and clear debris from the pump impeller.
  3. Inspect the drain hose for kinks and confirm it is not inserted more than 4.5 inches into the standpipe.
  4. Reinstall the filter, restore power, and run Drain & Spin with an empty tub.
  5. If F21 persists, test the drain pump — humming with no flow means a failed pump.

Call a pro when: Call a pro if water leaks from the filter after install or the tub still holds water after pump replacement.

What F21 means

Questions about F21

What does F21 mean on a Kenmore washer?

F21 is a long-drain fault — the washer could not empty the tub in time.

How do I reset Kenmore F21?

Clear the drain path, unplug for 5 minutes, and run a spin cycle. F21 clears after successful drainage.

Do I need a pump for F21?

Clean the filter first — replace the pump only if it fails to move water after the path is clear.

Is F21 the same on Whirlpool washers?

Yes — Whirlpool-platform front-load washers use F21 for the same drain timeout fault.
