Hi Alan
It does this right at the start of the cycle then before it's full of water?
F21 22 error code is CCU/TOUCH-PAD/LED ASSEMBLY ERROR
This error occurs if the touch-pad/LED assembly is not able to transmit/receive data to/from the central control unit (CCU).
Possible Causes / Procedure 1. Check the touch-pad/LED assembly by selecting different cycles and changing the modifiers and options available to confirm the touch-pad/LED is responding. 2. Unplug washer or disconnect power. 3. Check wire harness connections to the touch-pad/LED assembly and Central Control Unit (CCU).
Here is a copy of the tech sheet with some more information, maybe it will help.

When you start the cycle is stops at 21 or 22 and displays "F". Then the unit will not start.
