Troubleshooting a Whirlpool Duet Washer with an F11 error code and repairing it without replacing parts

Whirlpool Duet washer F11 repair wire harness CCU MCU
Many appliance servicers have been befuddled by the elusive and mysterious F11 error code in these Whirlpool Duet front loading washers (also sold under the Kenmore brand). In their confusion and frustration, many will go into Parts Changing Monkey mode and start blindly replacing expensive control boards without really fixing the problem (but still charging the customer, of course).

The Appliance Guru never does business that way. Customers hire me to solve a problem. Period. I give a quote up-front for the complete repair cost and I stick to it. If my diagnosis is wrong, that's my problem, not the customer's and it won't cost them a penny more than what I quoted.

How can I offer professional appliance repair services this way and stay in business? Well, it means I better know what I'm doing and be able to do real troubleshooting, not just throw parts at the problem and hope to get lucky.

The infamous and all-too-common F11 error code in these Whirlpool Duet front load washers is a case-in-point. The tech sheet inside the washer says this is a communications error between two control boards: the CCU (central control unit) and MCU (motor control unit). Even Whirlpool's own technical guidance for this error is abysmal; they say to replace the CCU and if that doesn't fix it, then replace the MCU. This is why there is so much confusion among appliance repair techs in the field. Each of these control boards costs well north of $200 and the CCU in particular goes on frequent backorder, adding lots more cost and inconvenient downtime to the customer.

As I show in the video, the F11 error code problem in these Whirlpool Duet washers can almost always be repaired without replacing any expensive control boards. It's at least an easy and inexpensive repair to try before replacing the CCU or the MCU.






AWESOME, Scott! Thanks much.

Domo, dude!  Hope it helps on your calls!  

Nice solder job! Thank you for the tip.

Domo, Bob.  I could have perhaps been a tad lighter but it did the trick!
