HOTPOINT DISHWASHER FDW60
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.
