Hello, I wonder if you might be able to help. My Bosch dishwasher SGV56A03GB/42 is not heating up. It looks like the top spray arm is not moving though some water is coming through. I took the arm off and the part that feeds the water to it under the rack and neither semms to be blocked. last time it was running cold washes it turned out that a little rotor down by the filters was stuck. I have checked this and it seems to be moving freely. PLease could you advise? Thank you
Re: Bosch dishwasher not heating
is the dispenser opening? im assuming machine is draining ok too, otherwise it wouldnt be turning the arms
run it on the warmest of the middle programs (not rinse or hotter ones with a prewash) with the tab dispenser shut and free from obstruction (the slide type ones can suffer from teh disp seal coming free and/or spring pinging out and wedging it shut)
water should have heated up above room temp well within 30 mins, and the dispenser should have fired open. if its still shut is most likely to be the pcb, if its open, look towards ntc stat and element.
either way, not an easy diy fix unless your experienced with playing with bosch neff or siemens d/w, pcb clips can easily break, and theres a knack to getting inside the lower reaches of the machine, less hassle to pay an engineer tbh, and they can often save you a lot of money if it is the pcb, by getting it repaired, rather than replaced, which is expensive option.

Hi, thanks for your reply.
I hve got into the habit of just throwing the tablet into the bottom of the machine as it seemed to be ejected into the wash almost immediately anyway. I will put one in the dispenser and see what happens!
Re: Bosch dishwasher not heating
The tablet ejected ok. PLease could you tell me if you can thinkof anything else I can try? Thank you
First check is the water level. Once the machine is up and running , approx 5 mins in , open the door and check how much water there is in the base. It should just about cover the base and reach approx 1/3 up the salt pot lid.
Low water levels due to a blocked pressure chamber and hose are the most common cause of no heating faults in these machines .
