BOSCH SGV4313GB/12 ‘ stopped’

[bbbbb]

Hi Folks, my trusty Bosch dishwasher which has given excellent service has failed.

When summoned by she who must be obeyed, I found water in the bottom and the 3 right hand LEDs (of 4) staying on ( Normal, Eco & Quick , so X 0 0 0 as looked at from above) and the programme will not ‘end’.

I have checked the waste pump and it runs OK when I lift the red rod). The main pump is inactive but I can rotate it by hand (so it does not appear to be jammed.

I’m unsure if the mains water feed valve (on the hose is operational or not (I don’t hear or feel it operating) when I turn the elec mains off and on. However as the LED code (above) is displayed I thought it best to try and understand this before going any further.

Any manuals, error code info or advice appreciated.

Can`t look up your fault codes. But usually when Bosch do your fault or something like it is something to do with the pressure switch assembly or its micro switches to the left of the red float rod you moved up to switch on the outlet pump. Is the other m/switch with the ,usually blue, lever triggered by the pressure swt?, Does this assembly look blocked up / dirty is the sump hose blocked up -very common. Clean all this (power off of course!), disconnect the inlet pipe then reconnect the inlet pipe and then see if it fills up. If you have to remove the micro swt wire blocks mark them so you do not x them and you refit the right way round i.e. not upside down on the wrong terminals – very important. The assembly does detach from the base- watch the water from the header container since you have to remove it to get the assembly out. Watch you do not lose the rubber o rings too (-look at where they go first, you`ll see them) in all the fun as the water comes out. If you careful it is possible to dismantle the p/swt assembly and get it back together in one piece. part number for the p/swt assembly is BSH263186 ABOUT £27.00 should you want/need one. This is a bit of a guess as I said I do not know the fault codes so I could be wrong and misleading you but worth a try.

Thanks Andy, I spent a bit of time on this yesterday and checked and verified all that I could (micro switches, aqua-stop, heater element, etc without finding any fault.

Decided then to look and the control module and found that the 3 pin (extreme right connector)was burned where it connects with the control module’s PCB and the corresponding control PCB connections were also burned. I hard wired the connections and the symptoms changed in that I now have a full set (4 Leds) instead of the previous 3.

So kinda looking like the control module as the prime suspect, though I have still to trace the wires through the m/c to see what they feed.

At £140 for a module and with no certainty of a compelte fix it may be time to cut my losses and by a new m/c as this one is 13 years old (it has been trouble free so I will be sorry to see it go)
