Re: Bosch dishwasher heat pump saga
these heaters are a pile of junk. the old heaters seldom failed but these ones seem to be printed on a steel tube a far cry from the standard solid element
From posts I have read from Martin and others there are a number of things that can blow them
1 Water flow anything that lowers the flow rate can blow them blocked filters, blocked wash bars and water diverter valve
2 pcb relay sticking turning heater on with low water
