Re: Bosch SGS5002GB/07 timer stops/not heating

I removed the sump and heater and pumps and nothing appears broken or blocked, I even took the heater apart to check the diaphragm that operates the microswitch. could it be the thermistor faulty ?

Re: Bosch SGS5002GB/07 timer stops/not heating

can the pump be removed for inspection without removing the sump ?

the impeller looked ok in the mirror but seemed stiff to turn, I think the arms do rotate but not sure if they rotate properly, hard to tell with the door closed.

Hi Martin I checked the above and no obvious problems seen. do I need to take the sump unit out for closer inspection or is there anything else you can suggest ?

Thanks martin, so may not be a heater problem then, I will check what you suggested,

Re: Bosch SGS5002GB/07 timer stops/not heating

Hi Martin ,
I googled part 00165385 and it came up as cycling thermostat or temp regulator. I found that when I heated that part with a hairdryer it changed from open to short circuit .
I refitted it and tried heating it but the timer still wouldn’t advance. I then checked the heater connections and got a reading of 22 ohms so it appears to be ok. I checked the voltage across it and at no time did it have a reading. however the microswitch that sits on the element plastic housing has voltage with reference to the one side of the heating element so it seems that the microswitch is not being activated. the switch seems to be activated by a plunger that comes out of the element assy. and its supply comes from a unit on top of the plastic housing, I presume this is a thermostat. do you think changing this whole assy would fix the fault and does it come complete with element/thermostat and microswitch ? also do you know the part number as I have been unable find it.
thanks for your help , phil.

Thanks Martin, so the thermostat I tested could be ok, would I right in thinking that the thermostat closes when it detects that the temperature has been reached , and that the heater may be the problem, there doesn’t seem to be a pcb behind the controls, also do you know if the heater is accessed from the side or the base on this model ?

Thanks Martin , I shorted it out but still the same, I will check the heater element tomorrow, if it is faulty would that also cause the timer stopping problem ?
