I have a bosch sgs502gb and it only seems to work on the eco 55 degree setting . Any higher temp or lower temp and no heat at all seems to get into the wash area.Even at 55 its not fully up to temp and some pots come out dirty.I have been told it could be the PCB is that plausible or something else?thanks.

if its not heating it at all it more than likely be the board 9 out of 10 time it is but if its heating ok then check the rinse aid might need topping up.
