Whirlpool washer error F21 – Long drain time
Is your Whirlpool washer stuck mid-cycle or taking too long to drain? The F21 error indicates a drainage issue, which can leave clothes soaking wet at the end of the wash.
Common causes:
- Clogged drain pump filter
Lint, hair, and small objects can block the pump.
- Blocked drain hose
A kinked or clogged hose prevents proper water flow.
- Faulty drain pump
If the pump isn’t working, water won’t drain effectively.
- Control board malfunction
A miscommunication between components can cause drainage delays.
How to fix it:
- Clean the drain pump filter
Remove debris to restore proper flow.
- Inspect the drain hose
Straighten kinks and clear any blockages.
- Test the drain pump
If it doesn’t operate correctly, consider replacing it.
- Reset the washer
Unplug for five minutes, then restart to see if the error clears.
Pro tip
Check pockets before washing—small objects like coins and hairpins can clog the pump.
