Bosch dishwasher heat pump problems

Hi,

I was just wondering if anybody else has been having problems with BSH heat pumps in the newer style dishwashers. I’ve been fitting them regularly for some time now, a nice easy job albeit the price of the part but this last week ive had two of the parts bounce. I fitted both of them within a week of one another about 2 months ago.

They seem to be going left right and centre at the moment for me. I must get at least 1 or 2 a week and if the new ones are going to bounce on me Im not sure im going to recommend customers having them done.

It came to my attention from speaking to a few of the previous owners that previous to the heat pumps going they put a dishwasher cleaner through the machine and it was my understanding that maybe the cleaner foamed up a little too much and the heat pump was heating foam up rather than water and overheating. Ive checked with the latest two customers and they swear they haven’t used a cleaner and there was no foam in the machine at the end of the faulty cycle.

I was just wondering if anybody else has been having similar problems with these heat pumps or have I just had an unlucky week.

Thanks

Nick
