Hello world.
It’s the first time I’ve used a forum, so fingers crossed.
I have an AEG OKO Lavamat 610, which I reckon I must have had 15yrs now, from new. Other than the conditioner dispenser rarely dispensing conditioner (despite syphon being in correctly), I’ve never had a problem with it.
Two days ago the programme selector switch appeared to get stuck on pump out, and wouldn’t go on to spin. It just sticks there until you switch off.
I’ve taken the back off and had a look inside for any obvious signs of a fault. The only one that jumped out was a sign of scorching on the thin transparent plastic flexible sheet covering the pcb to the rear of the programme selector switch, centred to the rear of the pcb, directly above the gap between where the two sets of leads plug in.
I’ve no idea how to diagnose further. Any help would be really appreciated.
I feel lucky it’s done me 15yrs without complaint. Is it ready for the laundry-room in the sky, or worth repairing/keeping??The info on the sticker is as follows:
E-Nr.605.637 203
F-Nr.074246264Thanks in advance.
Re: AEG OKO Lavamat 610 Electronic
Fine old machine, should be just about run in by now.
The scorching of the plastic drip cover is entirely normal – directly underneath is a large wire wound resistor on the pcb on the end of the timer and it does get hot.
First thoughts would be the water level control system – if the machine does not drain promptly, or the level switch does not drop out, the timer will not advance to spin. If you advance it manually, will it spin?
Check that the door is actually locking and that all the option buttons are out.

Re: AEG OKO Lavamat 610 Electronic
Hi thanks for quick response.
Liking the comment about it being just about run-in – hope you’re right!
The scorching is really localised – maybe the size of a fifty pence, maybe a bit smaller, which made me think it might have been the problem, but I guess the heat could easily have been rising through the gap between the connectors. I have pictures if it would help, but couldn’t work out how to attach?!?
I’ve tried manually advancing the programme, but nothing happens – the machine continues doing what it’s doing until you switch off. I’m pretty sure it’s stuck on pump out – the noise is familiar, not grinding or anything else that sounds unfamiliar.
The door’s locked properly. I manually emptied it last night and checked the pump impeller is free. And all buttons are out.
Any more pointers? Again thanks in advance. Great service by the way.
Re: AEG OKO Lavamat 610 Electronic
Why did you empty it manually? The pump should drain the water, the water level switches should click down as they’re de-pressurised and the the timer should advance to the spin position. If the machine thinks that it’s full of water, it will hold at the drain position for ever…

Re: AEG OKO Lavamat 610 Electronic
Sorry Penguin, the pump had drained the water.
Meant to say I wanted to check the pump impeller wasn’t jammed, so used the plug/hose in the bottom corner before checking the impeller.
Re your point “If the machine thinks that it’s full of water, it will hold at the drain position for ever…” – do you reckon that’s the problem?
Re: AEG OKO Lavamat 610 Electronic
Right – you need to get a bit “hands on” to eliminate the water level switch. It works on air pressure, from a collecting bell under the machine. This can simply get choked with crud and not release thet air to let the switch drop out. The level switch iteslf is round and has a small rubber hose attached to it. When (gently) pressurised, you should hear the switch click over 2 or 3 times (Don’t remember – it’s been a while..), when the pressure is released, you should get the same numer of clicks going down again. Blowing back down the air hose should show no resistance – if it does, a strip and clean out of the airbell in the bottom may be required.
Power off before trying any of the above….

Re: AEG OKO Lavamat 610 Electronic
Thanks for that. I’ll give it a try.
Connected it all up & had another look at it last night, manually advancing the timer.
It fills fine, and pumps out/drains fine. It refuses to agitate or spin. Not sure if this adds anything??
Re: AEG OKO Lavamat 610 Electronic
Hi Penguin
Checked WL switch and it clicked as you said.
Blew down rubber pipe with no resistance.Had another good look, and one or two wires show signs of blackening (including some of the ribbon type multiple wires). Is this what you’d expect on a machine this old or poss sign of the problem??
Do I need to consider getting motor checked out?
Any more suggestions appreciated – her indoors getting twitchy – she’ll need sherpa’s to tackle the washing pile.
Re: AEG OKO Lavamat 610 Electronic
Forgot to mention – the other half tells me she’d been washing a small rug – v heavy when wet. Could an out of balance switch been activated? If so would it reset itself, or does it need doing manually. I would have thought he former?!?
Re: AEG OKO Lavamat 610 Electronic
Back again…
Spoke to local repair/spares shop this morning & they suggested it might need new brushes on motor, bearing in mind machine age. Took motor over, they fitted new brushes, motor back in, no change. Bit stuck what to do next.
One thing I’ve noticed, again not sure if it means anything, the programme/timer dial can’t be heard to be clicking round at all, and I’m sure you’ve always been able to hear it quietly clicking away in the past??

for my 2pennyworth penguin is a1 with this – in the space of 2 months just done 2 handle and interlock replacements on these. initially we were also weary of the plastic scorching due to the cost of the interlocks (£40ish), but after the first “step into the dark” it doesnt seem to be a problem! after all the plastic is only there to stop condensation and water vapour dripping onto the board!
Re: AEG OKO Lavamat 610 Electronic
The motor is running for wash and the intermediate spins, I take it?

Re: AEG OKO Lavamat 610 Electronic
No. No movement at all from motor. Nothing.
I’m reluctantly beginning to think it might have washed its last wash. Unless you can shed any more light. Would really like to keep it going if poss.
By the way, I’ve been quoted these costs for parts, should I go down that route. I’d be interested to hear your view Penguin. These were from the same repair shop which replaced the brushes. They seem a trustworthy outfit, so I’m fighting the urge to suspect they’re just steering me towards a new purchase, rather than repair…
Motor – £470, Timer £372, Module £194.
Re: AEG OKO Lavamat 610 Electronic
Came across this advice on another post…
“sounds like the commutator needs ‘dressing’ …use very fine emery and spin the motor by hand whilst holding the emery against the copper segments to polish them, then brush them out (an old toothbrush is ideal)
The brushes also need dressing…use a file to carefully file a taper on the sides of the carbon brushes…about 1mm should do the trick. “Worth a try on my new brushes I wonder??
