This Whirlpool Duet Washing Machine ( GHW9150PW2 ) is giving an F 11 Code. This means there is a communication error between the Central Control Unit ( CCU ) and the Motor Control Unit (MCU). This is where it gets tricky. Which one is the problem and which needs to be repaired? I checked all of the connections to make sure they were secure. They were. I will have to get a service manual and run some diagnostics tests to determine the problem and what needs to be done to repair it. My gut tells me it’s the CCU but I need to be sure before I start replacing expensive parts.

Went back with the repair manual. Yesterday I made sure all of the connections were secure at the CCU. I should have done this at the MCU as well. Today I saw the problem. The picture will show where the MCU was burned. I replaced the Motor Control Unit and now everything is working properly. You want to always check your connections and look for loose wires and/or burned terminals.
