      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

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

Samurai Appliance Repair Man

18,346 views

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.

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