Customer Questions and Answers for Electronic Control Board by Whirlpool

JL, First off, your "F11" error code, indicates the MCU and the CCU aren't communicating, Check the wire harness between the two controls.Now, You have three electronic control/PCB assemblies in your washer. The "user interface"/ UI WP8540490 This is basically the selector buttons and selector dial assembly. The "Central Control Unit" / CCU WPW10525359 is the "brain" of the system, all the sensors and boards input the information and the ccu determines what to do.The MCU/Motor Control Unit WPW10163007 this component tells the motor what it needs to do, and sends a signal to the CCU, at the same time, so the CCU can determine if the washer is operating properly. Apparently you need the MCU, based on your post. Thanks and Good Luck

Hello Mike. Here are the instructions from the manufacture for a F-28 code. Hope this helps. Possible Causes/Procedure 1. Unplug washer or disconnect power. 2. Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU). – Check connections of the CCU board within the housing. – Make sure all grounding switches are engaged. 3. Check the drive system for any worn or failed components. 5. Plug in washer or reconnect power. 6. Verify CCU operation by running a Diagnostic Test or any cycle. 7. Check the MCU by looking for operations of the drive motor. 8. Check the drive motor for powered rotations. 9. 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.
