Bosch SGV53E03GB/50 No heat

[conormccleane]

Hi,
Customer reports this integrated d/w tripped RCD a few times. Brought it back to workshop. Put ammeter on and let it run 50 deg prog but no heat. Elements measuring OK. Not sure if taking in enough water. How do I check this?
Fairly new to bosch stuff so appreciate some guidance, but ready to learn.
Thanks,
Conor! 🙁

The water level , when full , should just about cover the whole of the base of the appliance and reach about 1/2 way up the salt fill cap. A Low water level is the main reason for no heating faults on these machines . Check the pressure chamber and ribbed fill hose – pressure chamber to tub – on the left hand side for blockages . Low water levels won’t cause tripping though !

If the element is def ok ( 24 – 32 ohms ) then the other thing to check is the main control board for dry electrical joints or blown chips on the heater circuit.

It might be that the water diverter valve has blown taking out the board with it ! Look for intergrated circuit chips on the control board with ‘corners’ blown off them .

Thanks nomad,
All check out ok. I did notice a lot of suds in the cabinet, rinse aid I suspect. Flushed through a few times and mopped out. Heating ok now – must ask customer if she spilled rinse aid in cabinet – that might explain tripping RCD’s.
Regards,
Conor! 😀
