We recently had a flood in our basement and our washing machine had ~ 2' of water around it. Once we pumped all the water out of our basement I took the front panel off the washing machine and let it air out for two days. Once I hooked the washing machine back up and ran our first load we received an F-11 error code. After doing some research online I unplugged the machine, made sure all the connections were tight, and tried a load again. Everything ran as I would have expected it to. Once that load was finished I tried a second load and about half way through that load I received the F-11 code again. I unplugged the machine and ran another load and this time it worked. However, now I am receiving the F-11 code consistently when we run full wash cycles. I am able to run the Spin and Drain cycle consistently without any issues so I assume the motor is good. Since the Motor Control Unit was under water I assume that is what needs to be replaced (Part #8182706) but before I spend the money on the MCU I was hoping there was a way to test out my machine to make sure this is what needs to be replaced before making the purchase. Any assistance in resolving my issue would be appreciated.

Steven for Model Number MFW9800TK0

ANSWER Hello Steven. Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly. Possible Causes / Procedure 1. Unplug washer or disconnect power. 2. Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU). 3. Check the drive system for any worn or failed components. 4. Plug in washer or reconnect power. 5. Verify CCU operation by running a Diagnostic test or any cycle. 6. Check the MCU by looking for operations of the drive motor. 7. Check the drive motor for powered rotations. 8. Check that the serial harness at the MCU is not mounted upside down. The wires should be to the left when facing the MCU connectors.
