Hotpoint FDW60 dishwasher. not heating. How /where do i test the pcb to check if faulty ??

These two lights indicate a fault in the heating circuit.

You would require to have access to and be able to use a multimeter to test the heater if the machine isn't actually heating the water.

If it is heating the water then obviously we know the fault isn't with the heater.

Check the heater first.

Take the door apart and check the wiring in the door isn't broken.

If everything checks ok, take the pcb out, look for burned or dry joints around the relays.

If the original light flashing that means it indicate a fault in the heating circuit. Heater, wiring, thermistor / pcb. (Main control board).

The new flashing light, PreWash (this is the only one on my list for a fault code indication). indicates a fault with the thermistor.

You would need to check by taking the door apart that the thermistor hasn't come off it's mount by the dispenser.

You would then need access to and be able to use a multimeter to test the heater and wiring to ensure they are closed circuit.

is it heating if so check spray arm and filters are clean it is washing i take it.....

I had the same problem. found out that the RCD was faulty & needed replaced. now o.k.

If the heater is ok and the wiring is also not burnt out, then the fault will likely be the heater relay on the pcb. (Which means usually replacing the board).

I had the same problem with my Hotpoint FDW60 and read all the online reviews about how baddly made the FDW60 is and after taking it apart I totally agree.

As the warning lights were indicating a faulty heating element I checked it to find that it was not working. I bought a replacement for £43 at my local electrical store (I think they then ordered it online). Taking the bottom off is easy but once off, it is very difficult to actually get to the element, but it can be done. I had to buy new hose clips to fasten the rubber pipe each side too. It has been on twice today and so far so good.

I have read some message boards and have seen that some people have had to replace the element a number of times, so I will wait and see what happens.

Be aware the heating element is not your usual heating element, it looks more like a insulated metal tube: http://www.buyspares.co.uk/cgi-bin/search.pl?query=heating+element+fdw60

Good luck

The pcb will be damage , check to see if you have 5 years parts all hotpoints have them it will be cheaper to fix.

Hi,

I have just had my dishwasher fixed by Hotpoint, as the heater was working and the dishwasher only stopped with the fast and delicate lights just before the drying process he replaced the main control board. This has solved the problem, I suspected the fault to be the thermistor as the heater seemed to be getting to hot but I had no idea where it was.

It turns out the thermistor is attached to the main control board and hangs down behind the front door that gives just a rough temperature level for the main control board.

As it's soldered directly onto the control board I would suggest replacing the whole control pcb for anyone with this fault unless you can find any spec details for the thermistor.

Wash motor either seized up/ faulty or the is an itme jamming up the impeller. Regards Advisor

is it heating up properly? if so the pcb may be faulty.
