When the F21 error number appears on your Whirlpool washer, it usually means that the water draining process is taking too long. Whirlpool front-load models, such as the well-liked Duet series, frequently have this problem. Thankfully, you can sometimes resolve the issue on your own without having to pay for a pricey service visit.
What Does the F21 Error Code Mean?
Whirlpool washers with the F21 fault code have a “long drain” issue. Water should normally drain from your washer in 8 minutes. The machine will immediately stop and display this error if it doesn’t.
Among the primary factors are:
- A kinked or blocked drain hose
- A clogged trap or pump filter
- A malfunctioning drain pump
- Control board or electrical problems (less frequent)
How to Fix F21 Error Code Whirlpool Washer
Here’s a step-by-step guide to troubleshoot and fix the issue:
1. Check the drain hose.
- Unplug the washer and push it forward a little.
- Check for kinks, twists, or obstructions in the drain hose.
- To make sure the hose is clear, run water through it.
2. Clean the filter on the drain pump.
- Lift the washer’s lower front panel, which is often fastened with screws.
- To catch water, use a towel or shallow pan underneath.
- Remove any coins, lint, or debris by unscrewing the pump filter lid.
- Before restarting the washer, firmly replace the filter.
3. Test the Drain Pump
The drain pump may be malfunctioning if the washer still won’t drain even after the hose and filter are clear. When there is no water movement and a buzzing sound, the pump is probably broken and needs to be replaced.
4. Perform a Whirlpool Duet F21 Reset
Sometimes, after clearing blockages, the error code remains. To reset:
- Unplug the washer from the power outlet for at least 5 minutes.
- Plug it back in and press Start.
- This Whirlpool Duet F21 reset can clear the error memory.
Sometimes, the error code persists even after blockages have been removed. To reset:
- Disconnect the washer from the power source for a minimum of five minutes.
- Press Start after plugging it back in.
- The error memory can be cleared using the Whirlpool Duet F21 reset.
5. Whirlpool Duet F21 No Clog?
If the hose and pump are clear of obstructions, the issue may be electrical. The wiring to the drain pump or the washer’s control board may be faulty. Professional service is advised in this situation.
When to Call for Help
After completing these instructions, if your washer error code persists, you might need a specialist whirlpool appliance repair to check the pump or control system. Don’t disregard persistent drainage problems since they may result in water damage.
