Miele G4300i Dishwasher

[Raythewash]

Morning all,

I have a fault on this where the Wash, Rinse and End light flash simultaneously. It starts and runs for about 15-30 seconds then stops with the lights flashing, I have checked the motor, heater relay, pressure switches etc but the annoying thing is its intermittent as after I’ve checked everything it runs fine for a complete wash then plays up again 🙁
I can’t find any info on this fault code so any ideas or help much appreciated!

many thanks
Ray

it mayhave a pressure sw but does it have a reed sw on the water inlet ?

Thanks Dave, it does indeed although it checks out okay but maybe replacing it may be worth a pop.

I have had a couple of the Miele dishwashers recently with problems with the pressure switch on the side of the motor. One of them even gave the symptoms that you describe, if I remember correctly one of the two switches in it was not activating properly due to sludge in the diaphragm, as I was unable to clean the switch I replaced it.

Thanks Jem, I checked that pressure switch although the programme doesn’t get as far as even filling before the lights start up.
I changed the flow meter but no luck there 🙁

[electrofix]

do you get water flow ? or is it not even starting to fill

Dave

[Raythewash]

No fill, just approximately 15 seconds of drain pump!

[electrofix]

so the fill valve could be faulty, have you checked that ?

Dave

Hi Dave, the problem has been intermittent to make thing’s trickier, possible the valve could be going open circuit occasionally?
