ok so the unit will run ,and all appears to work in a automatic diagnostics mode .but not in a cycle automatically .
that can only mean the issue has to be with in the electronic control board itself (CCU Central Control Unit )
That should not have been cause by the sock.
But the main CCU board may need to be replaced.
If you have not already .lets unplug or turn the circuit breaker off to the unit to kill all voltage to the unit for more then 5 minutes.
This will allow the memory to be drain from the electronic control boards memory chip.
If that DOES NOT work.
The CCU control board will need to be replaced .
If it need to be replaced.
