Cold dishwasher

[Tinwormhunter]

Hi, we have a Hotpoint BFI 620 Dishwasher that is not getting hot on the wash cycle, does anybody know were the heater element is on these.
Thanks Ken.

The inline heater is mounted between the external hard plastic pipe & a rubber hose that goes to the pump housing on the wash motor. Probably would be easier to get at it if you lie the dishwasher on its back & take off the bottom plate. Confirm if is actually defective before rushing out to buy a new one. A no-heat problem can have other causes. A good element should read 25 - 30 ohms.

Thanks zipper i'll try that and let you know.

I've checked the heater element and this checks out okay at 30 ohms.
Does anyone know were I can find a wiring diagram on a web site.

Thanks Ken

You won't get a wiring diagram at all. You need a new pcb, heater relay is faulty on the pcb.

Check for loose connectors/broken or burnt wires in the heater circuit before rushing out to buy spares. Hotpoint pcb's are not that expensive, but unfortunately quality is often reflected in cost. However it is still cheaper to buy a new pcb than a new machine. It is not possible to supply wiring diagrams.

All the connections in the bottom are like new, were about is the PCB hiding, I'll check that next, I've checked the water temp with an infrared thermometer on the tube at the back and it only rose from 16C to 21C so its got to be a controller problem.
Thanks Ken.

PCB is in the control panel. Remove the screws on the inside of the door to get at it. Good luck

Thanks for your help, it was the cicuit board in the end, even though the parts shop doubted me and asked me to bring the heater element in for testing first. £50 for a new card and its as good as new.

Thanks Ken.
