Right after my washer start filling up with water the F-H code shows up.
Is there something wrong with the CCU?
Thanks so much!
Answer Hello Julienne. Possible Causes / Procedure

on all the way.

What does it mean when my washer shows F11...does it mean that the computer board needs replacing?
Answer Hello EWS. Communication between the Central Control Unit (CCU)
and the Motor Control Unit (MCU) cannot be sent
