Whirlpool Duet Washer GHW9400pw4 F06 error code

My Whirlpool Duet Washer recently started acting up on me.  The washer would start a cycle, however during the cycle, the washer would stop, emit several loud repeated beeps and display F06 on the control panel.  Often, I could unplug the washer, wait an hour or so, and then after restarting the cycle, it would run to completion.  I began to notice that this only would happen during the summer when the temperature in the house was higher than normal.  In addition, it would happen more often when I had a very large load of laundry.

I begin to research what the issue could be.  First I downloaded the Repair Manual and ran the diagnostics.  These always completed successfully.  I than read reports that the MCU (Motor Control Board) can cause this issue.  It would seem that the unit overheats, or has poor solder joints that open when hot.  To test that theory, I removed the lower kick panel and placed a fan in front of the MCU.  I was able to run the washer for several months this way, it turned out to be a good short-term solution, and confirmed that the MCU was the culprit.

Eventually, this trick was no longer successful, and the dreaded F06 error returned.  I was able to buy a replacement MCU, part number W10756692 (also 461970300683) which is used in many Whirlpool Duet Washer models such as the GHW9100lw1 and other Kenmore and Bosch washers.  The retail price is usually around $250 new, but I found a used MCU on Ebay for $50.

Replacement is simple, remove the lower kick panel.  Detach the MCU after unplugging the five electrical connectors, and reassemble with the new MCU.  Always remember to unplug the washer before attempting this repair!

With a new MCU, you should find that your Whirlpool Duet once again works like new.
