AEG Oko Lavamat 61300 - washing machine overfilling

[Chris993C4]

Our AEG washing machine has started overfilling - typical, we've only had the thing 12 years

I'm guessing that it's a blocked or faulty pressure/level switch somewhere - the filling doesn't seem to be timer-controlled.

Before I get stuck in, does anyone have any tips - or even pointers to a service/repair manual?

TIA

On my Bosch the pressure switch was at the top, near the programmer, with a thin tube running down to the drain hose area. This bit at the bottom was blocked up with detergent & bits of scale. It was a bit of a pig to get apart but once cleaned out all was good.

As Mr Pointy says; probably the pressure switch. Take the top off the WM and pull the plastic pipe off. If you then blow down the pipe, you should be able to hear the switch clicking on and off (if working). If no click, the switch is probably gummed up and needs to be taken off and cleaned out. Good luck!

Thanks for the replies

I've whipped the top off the machine (two screws at the back, then the top slides back and up/off) and found the pressure switch - a roundish reddy-brown plastic unit at the top/left/rear of the chassis.

I'll disconnect the pressure hose and give everything a good test/clean later...

Thanks again!

I think Laurel means blow into the pressure switch, not the pipe you just pulled off and blow gently or you will flaff it up. and, please UNPLUG THE MACHINE before doing anything.

Almost ceratinly wont be the pressure switch,they very rarely fail. It will be either the pressure hose leaking (maybe the drum has been rubbing against it) or the air bell hose it originates from is blocked. On that model the cabinet front is removable to access it.

Now sorted

Gently blowing into the pressure switch, the microswitches inside clicked three times (multi-level switch) with increasing pressure - and once again when releasing the pressure.

The pressure hose itself was blocked with detergent sludge, but some gentle back pressure from a bicycle pump soon sorted that out - you can hear the air gurgling back into the drum.

Several washes later, everything appears to be functioning normally - happy days!
