Chris for Model Number ghw9400pl4 Get f11 code on a GHW9400pl4, went through diagnostic and stops on c:002 with a f11 code coming back up. What should I check or replace?
Answer Chris, The F11 error code is a serial communication error. You will want to do the following: 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.
