Just in case anyone else comes upon this problem..
When I tried to use my openevse I built from kit I was getting the message
Diode Check Failed.
It turned out the pre-wired CCS handle and tail I'd bought from China (to avoid the shipping from Europe) had the CP/PP pins swapped.
The plug was labelled correctly just the pins swapped.
Interestingly the phase labels are transposed but are pinned correctly.
