Amana Washer Error Code F21: Meaning and Fix
Reading the washer display
On a washer the code appears on the digital display or as a pattern of flashing cycle lights. Note it exactly, including any dashes or sub-codes, then unplug the washer for five minutes and run a short drain cycle to see whether it returns. Amana models often flash lights instead of printing text, so count the flashes.
Amana is a Whirlpool Corporation brand sold mostly through builder and value channels. Its entry-level washers, dryers and ranges use the simpler Whirlpool-family control boards, so the codes are short and often shown as flashing lights. The codes apply to model numbers such as ADB1200AWS, ADB2200AWS and NDE2330AYW; check the label on your unit to confirm yours.
What causes F21
- Drain hose or standpipe is kinked, clogged or set too high
- Drain pump motor is failing or its wiring is loose
- Too much detergent created suds that the pump cannot clear
- Pump filter or impeller is jammed with lint, coins, glass or debris
How to fix it
- Cycle the power: unplug the washer (or switch off its breaker) for five minutes, restore power, then start a short cycle and see whether the code returns.
- Switch the power off and check the drain hose for kinks and make sure the standpipe or disposal knockout is clear.
- Open the pump filter or access panel with a towel and tray ready, and remove anything blocking the pump.
- Run a rinse-and-spin or drain cycle and watch whether water leaves; a humming pump that does not move water points to a seized impeller.
- Replace the drain pump if it is jammed beyond clearing or its motor will not run when power is applied.
- Run a full short cycle or function again and confirm the code stays gone before putting the appliance back into normal use.

Questions
What does F21 mean on a Amana washer?
It is a fault code from the Amana control. It indicates a problem with the drain system. A power reset is the first thing to try.
Can I keep using the washer while it shows F21?
You can try it after a power reset. If the code returns, the affected function may not run properly, so it is worth fixing soon before it causes a bigger failure.
Do I need a technician to clear F21?
Many owners can fix it themselves. Start with the reset and the inspection steps, and only call a technician if the part tests bad and you do not want to replace it.
