Hi,
Went to a Bosch SGS43E02GB/43 DW. The machine fills, washes and cuts out during heat. All Display lights fade and cut off. If you tap the facia gently they come back and machine works for a while. I checked the loom, pcb and on/off switch for continuity. Had the door switch linked out, it still failed. Must be the on/off switch or pcb failing under load. Anyone else had the same prob?
Thanks for any advice

Hi
Sounds like a dry joint on the PCB, especially when under load heating, probably around the relays or transformer.
Take the pcb out of its case and have a good look at it, if you can’t see it by naked eye try a magnifying glass.
If in any doubt as to condition of joints resolder them.
HTH 😉

Hi Steve, thanks for quick reply.
I did check for dry joints and bad connctions, all looked fine.
It was a strange one, the customer was a RADAR engineer, had the machine apart and was as puzzled as me. I don’t carry many Bosch spares so didn’t have the correct on/off to try and ran out of time on Sat.

It is a strange one, but I have had it before with these boards, you have to get them in the right light to see it, and is generly hard to see by eye especially if on the lower ampage side of things. Never had an on/off switch fail like that, hardly ever replace them.
One other avenue worth exploring, as i had this last week is the socket especially if its behind the machine. The plugs are famous for sticking to the tar at the back and can lead to the plug being pulled in/out of the socket, poor connection around the plug pins etc, martindale tester is inconclusive as draws no load so maybe try a different socket? They are only drawing about 2amps until the heater kicks in and puts it into the region of 10.
I may have a board kicking around for this one but i’d have to have a look.

cheers Steve,
will prob quote him for pcb. I checked the plug, it had stuck to the back in the past! It failed while in another socket. Also lights coming back on with such a slight tap on the facia, must be around there. Did have a similar fault caused by poor neutral in the socket, worked ok on another that time. Thanks for the advice.
