If this is the first and forth LEDs then i was told by a Hotpoint engineer that this means 'heater cut out due to overheat' and that probably the heater is just covered in limescale. If that is the case then running a descaler through the dishwaer on the highest setting should fix the problem and clean the inside of your machine to boot !
I guess this would happen if your machine is a few years old and you live in a hard water area.

tung

this could be one of the water valves not working (not opening)

Sounds like needs new door interlock swith Cost around 15 pounds.....Simple to fit

sounds like you may not be getting enough water.it will stop if water is in short supply.this may be if you are running washer at the same time.or running a bath.if hot water is in short supply,this maybe a hotwater heater problem.have you been running out of hot water when showering or bathing?

Sounds like control switch is faulty. Check wires at motor first for corrosion or arcing.

f01 is a motor short circuit. you will probably need a new one and maybe the circuit board that powers it if all the lights went out unless the fuse is gone.
