well Bosch codes are never easy but from some digging am getting hits on a communication error

try checking connections between the boards

That’s a power board fault programmed part number 10017495 expensive though £206.62

Well just to close this one off – I don’t know for definate which component was the cause but I replaced all of the electrolytic caps and the 3 larger relays on the main board and it appears to have cured it.

may have been ac ripple on dc lines

well done

I wondered about that but the caps measured okay both on capacitance and ESR results, my suspicion is more with relay bounce (not cleanly switching) but I couldn’t prove it and the machine was too far away to make multiple trips to test either theory, either way I fitted the module back to the machine last friday, I know that they were going to be using it all weekend and have heard nothing to say that it has failed yet.

Yes I would say a relay fault as I’ve done a few and I hear the relays clicking alot

Definitely one or more relays fail …..couldn’t find in UK had to import on slow boat from China do ASWO stock them?
