Thanks for your replies! I’ve had some really good news, which is that after lots of letters and telephone calls and emails, Miele finally responded to a negative review on Trustpilot. In the end they have agreed to pay for the entire cost of the repair.

Bad news is that they are STILL waiting on a power control unit from Germany, so I still have no end date in sight for getting my dishwasher back in service.

Dave, to answer your questions, I think that the engineer was either employed directly by Miele or contracted by them. He wore a Miele uniform and had Miele paperwork, although he lives in a village not far from here.

I’m not entirely certain that the power shortage was his fault. When he arrived, he opened up the bottom of the dishwasher to check that everything was dry. As we hadn’t run the machine for several weeks, everything was bone dry inside. Then he took the unit out and swapped out the pressure control relay for a new one (this was, he said, the most common reason for an F51 error message). That didn’t change anything so at some point he lay the dishwasher on its back, checked a few other connections, and then put the machine upright again. He wanted to order a new logic board I think, so he was buttoning everything up when a screw rolled out of sight.

He went out to his van to get a new screw, and just as he walked back in the kitchen door there was an electrical pop and a burning smell. No one was touching the dishwasher at that time. The engineer was frustrated that it had happened, but I’m not sure what he did that caused it (or what he didn’t do that might have prevented it).

My guess is that there was a little water somewhere and during the process of tipping the machine onto it’s back and setting it upright, this little bit of water got into the power system and caused a short.

Anyway, now that Miele is going to cover the cost of the repair, it doesn’t matter who was at fault here. I’m glad that in the end Miele is being supportive and helpful – and I’m hopeful that we’ll have the dishwasher working again soon.

Thanks once again for your helpful thoughts here, I’ll update this thread when things are working so that anyone searching for this fault code in the future can get some information.

Thanks Dave, from what I’ve read that sounds spot on – replace the board and go through some configuration process. So probably not something I could do on my own. Thanks for that list of engineers, I hadn’t looked there!
