Whirlpool Duet GHW9400 PT4 on any of the cycles, runs 1/4 of the way through the was cycle and stops and starts flashing F 06, pushed cancel once then started the cycle again this worked for awhile. Then had to start pushing cancel twice and turned the dial to drain/spin. Still flashes F 06. Now Im luckey if I get my clothes washed and I can forget about spinning them out.

Maybe power was lost temporarily. Try pressing start / resume button. Or cancel cycle and start over. Also Check drain pump for obstructions.

I did as Drunan did and unplug for 10 and plugged it back in and it started like a champ! Thanks!!!!!! ;)

Your tech sheet i behind the bottom panel. I would consult that as to what the F-06 was all about.

Try unplugging the machine for 15 or 20 minutes and see if the computer resets itself. It worked for me.

If Pause/Cancel does not work:

Take care

flashes if the washer loses power during a running cycle. The washer does not flash FH" when it is first plugged in.

its probably a blocked water filter to this fabric water valve or the coil has failed on the valve,it should be 3800kohms,check the filter at the water inlet connection,hope this helps

I looked up the F02 code online and this is what it says:

If the drain time exceeds 8 minutes, the water valves are turned off and F02 is flashed.

Press PAUSE/CANCEL twice to clear the display.

NOTE: After 4 minutes the “Sud” error will be displayed, then 4 minutes later the F02 error code will be displayed.

Potential Causes

• Check the drain hose and make sure it is not plugged or kinked
• Check the electrical connections at the pump and make sure the pump is running.
• Check the drain pump filter for foreign objects
• If the above does not correct the problem replace the pump


Hope that helps.

f22 is a door lock error try this hit cancel turn your dial to another setting, hit start and once it starts hit cancel again and it should unlock. thats what i did anyway.
If you're getting an F22 error, you will want to check anything to do with the door latch switch.
