Hi
dishwasher is about 6 years old, and has just recently started to turn off mid cycle. All running ok up to that point, no error codes, it just dies.
Sometimes comes back to life a few minutes (and as much as 20) later and carries on. So you can get a full wash out of it, but takes a very long time.
Pre and quick wash cycles equally about 50:50 whether they will complete in one go or not.I’ve done all diagnosis, it’s not blocked etc. Could it be faulty PCB?
Thanks!
Hi Lokibear,
We have a Bosch dishwasher of a similar age exhibiting similar symptoms. I also suspect the PCB, but nobody seems able to tell me.
Did you find an answer?
Thanks!check socket at rear of machine for signs of overheating
try another socket just to make sureif all this ok then agree most likely board but you can never bee 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} till you swop it and find out

Thanks Dave. Sockets look good, and swapping didn’t change anything.
Any idea how much a replacement PCB costs? I’m having trouble finding a source for these…
Odilonask QER if they can repair it. does sound like a power supply chip problem
alternatively you can go to
https://www.bosch-home.co.uk/customer-service/care-protection-and-parts/spare-parts
to look for the part but you will need the last 2 digits of the model no

Hi Dave,
I’m thinking, before I spend £42.29 on the new PCB/controller module, is there any chance it’s a sensor of some sort. I observed the dishwasher more carefully last night, and it seems to hang up as it kicks into a new cycle about 2/3 through the programme (in this case the ‘speed perfect’ 50-degree wash). Some of the wash water is drained, then it hangs up at :37 remaining. I looked, and there was still hot soapy water at the bottom. The machine then goes off for a few minutes, then wakes up and tries to do something (sounds like a pump), then goes back to sleep. After a few of these cycles all the water was drained, but it keeps up the sleep-wake cycle (with many minutes sleeping, LED off) for a long time (>1-2 hours).
Does this still sound like a PCB, or should I look elsewhere?
Thanks!
Odilon
still sounds like a pcb but you may have looked up the wrong one
I cant say for certain but it sounds more like a power board failure and you wont get that for £43
Dave
Thanks Dave.
It seems the “control module” is £43 and the “power module” is £116 (on the Bosch site). Seems like the power module is far more difficult to access.
Do you know if it’s possible to DIY re-programme one of these power modules? Somebody has one (from a different machine, but the same module) for £30 on Ebay.
With these spare parts prices, it’s no wonder people just toss their old machines and buy a new one!
Thanks again,
Odilon
boards can only be programmed by the manufacturer as you need special equipment
did you as QER ?

they may be able to test the board, in fact you may be able to send both board and they may be able to check them as a pair
