I have an FDW60 dishwasher and the it has started flashing lights 4 (fast)and 6 (delicate) before finishing the wash. The dishes are clean and they look rinsed but it is not doing the drying stage.
The trouble shooting manual does not list anything about lights 4 and 6 flashing and Hotpoint want to charge £90 to fix it even though it is under 2 years old.
Does anybody have any ideas what this lights sequence means and how to fix it?
if the problem faults within the first 1 minute the first check the connections on the main module behind the control panel,as you you look at the control panel there is a pink connection to the left,if this looks like it has got hot then theres yopur problem(you will find that the joint on the board has come loose from the soldered joint,module requires replacing.
if this connection looks ok then the heater is open curcuit and will require replacing.
Hoppoint have e-mailed me that these lights ( 4 and 6) indicate that there is a fault with the heater circuit. But I have got no further than this with a repair. Not sure what to do. Please emial if you discover any further information on a repair. My dishwasher is under 2 years also.

A10 Open circuit in heating circuit.
• Check the circuit of the heating element (26 ohms).
• Check for an open circuit heater cut-out.
• Check pressure switch open circuit (connections 11-14).
• Check wiring and connections between module card, pressure switch and heater.
• If all above is OK, replace module card.
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.
