Question about Whirlpool Duet GHW9150P Front Load Washer
My whirlpool duet front load washing machine stops in the middle of its cycle (usually drain cycle). It flashes an F 21 on the display. What the heck is wrong
F21 = LONG DRAIN ERROR
If the drain time exceeds 8 minutes the water valves turn off. After 4 minutes the “Sd” error will be displayed, then 4 minutes later the F21 error code will be displayed.
Press PAUSE/CANCEL two times to clear.
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.
5. If the above does not correct the problem, go to step 7.
6. Unplug washer or disconnect power.
7. Replace the pump.
If the machine cannot be forced to its diagnostic mode then:
1. Disconnect the washer from the power supply and water supply.
2. Remove the top panel by taking out the three screws in the back of the washer. The pressure switch is right on top.
3. Remove the Molex connector from the water level switch / pressure switch.
Refer to the picture below.
4. Reconnect the power supply but not the water supply.
5. Power the machine. The machine will enter diagnostic mode.
6. Power off the machine.
7. Replace the water level switch / pressure switch.
8. Reconnect the water supply.
9. Power on the machine it will work without error
