    Default F21 codes - Appliance Tip of the Week...

    Appliance Tip of the Week...

    I have a 14 month old Duet Sport that has developed a problem which results in a F21 code. The service people changed the mother board but this did not help. The machine seems to work until the water needs to be pumped from the drum. We can hear the pump kick on and run until it cavitates continuously for a long while before finally displaying the f21 code. Any suggestions? Whirlpool is not telling us anything of value and have been terrible to work with!

    A copy:

    F21 is: LONG DRAIN If the drain time exceeds 8 minutes the water valves turn off. NOTES: After 4 minutes the ?Sd? error will be displayed, then 4 minutes later the ?F/21? error code will be displayed. Press PAUSE/CANCEL two times to clear the display.

    Possible Causes/Procedure

    1. Check the drain hose and make sure it is not plugged or kinked.

    2. Unplug washer or disconnect power.

    3. Check the electrical connections at the pump and make sure the pump is running.

    4. Check the drain pump filter for foreign objects.

    5. Plug in washer or reconnect power.

    6. If the above does not correct the problem, go to step 7.

    7. Unplug washer or disconnect power.

    8. Replace the pump.


    I'm having a problem with my HE3t washer. I select a wash option and then the start button and the washer does nothing. I do not see any errors codes at all. The door opens and closes with no problems. THe red light on the wash cycle select justs flashes. I've unplugged the washer for 5 mins thinking the washer needs to reset but still nothing. I've also cleared the drain but still the same thing. Any suggestions?

    Check your door switch button, its just above the door latch, sometimes that button has broken, or the door has dropped abit, not aligning correctly.
