AEG dishwasher – FSS62807P – 4 flashes

[twicknix]

Been out to this dishwasher as a second opinion engineer. First guy looked and ran off.

PNC: 911434536

The dishwasher flashes looks like i44 with red light flashing 4 times.

No blockage in filter.

Drain pump activated as if in flood mode.

Am I thinking the pressure sensor being faulty? They do tend to throw up some weird fault if the pressure sensor is malfunctioning.

if its got one of those little pressure switches in the sump, its more than likely that part no [h=1]140000554083[/h] when you remove switch, i would also use a small tube – to connect to where the pressure switch is fitted and blow steam in the sump , making sure its clean and free of sludge, etc

then fit new switch

Thanks, used compressed air to blow it out, connected new pressure sensor and fill sump with a couple of drops of rinse aid and half a litre of water to let it stand for 10 mins then start up dishwasher. This will stop the recurring fault as the new sensor will not work with the empty sump. Happened to me few times and found that my solution seems to have worked (?)
