Thanks Dave. So would you suggest I try replacing the lead and/or plug to the sensors?

I don’t think the leads are available separately, or are they? Bosch appear to charge £47 for the whole harness which is a bit steep for an experiment.

Thanks for the speedy reply Dave – much appreciated.

Yes, I am sure I have the right pump – the fact that the old one doesn’t heat up now also suggest to me that it’s something else.

And yes, the small white plug was a pain to remove and the wires may have been loosened in the operation. I suspected this might be an issue and did two checks: running the dishwasher with the white plug disconnected gave the same result as when it was plugged in (does a full wash okay but with no heat) – so perhaps there is no signal going back to the board? Second, I checked for continuity between each pin of the white plug and the board, but all were okay as far as I could tell.

Does that indicate anything useful?

Many thanks!
