Whirlpool Washer F21 Error Code

VERIFIED

Error code F21
Appliance Washer

F21 tells you that a front load Whirlpool washer has a drain problem. The only questions Whirlpool asks concern the drain hose.

Start at the hose

  • Run your eye along the drain hose. Is there a kink anywhere?
  • Is the hose clogged?

Then reset

  1. Pull the plug or turn the breaker off so the washer has no power.
  2. Wait 5 minutes.
  3. Restore power, run the washer and see whether F21 shows again.

The manual says a control reset can sometimes clear the problem.

Other front load codes

  • F20: the water inlet side: no water or too little
  • F22: the front door lock
  • F24: too much laundry for the program, or too much inlet water
