AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

Easy then if it’s an FHP motor 🙂

A pair of these inserts from the shop@ will do the trick:

Got the parts in the post the next day! Excellent service, and easy to fit too! Many thanks for your help.

One final small question though… I ran a couple of test ‘short spins’ to make sure every was OK again, and the drum seems to spin OK now and the motor sounds fine too. The only thing I did notice is that the motor seems to spark an awful lot at higher speeds (anything between about 1000 and 1600), which can been seen reflecting off the bottom of the machine through the holes in the back. Is this normal? Does it improve as the surface of the contacts become smoother?

Thanks,
Matt

The motor is arcing, probably due to excess carbon left on the commutator. Give it a good clean with some very fine emory and it should settle down.

I have replaced the brushes twice in my 72600 and used the ‘C9 reset’ each time and it worked perfectly each time, just as described by tfcgw.
I’m sure you guys can prove that bees can’t fly!

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

You miss the point. By accessing the test sequence any existing programme is over-ridden. Using the cancellation sequence, the programme is over-ridden anyway. Ideally, the power will be cut for the repair and the digi-board will “forget”.

Bear in mind that the information in these forums is provided by professional appliance engineers. We are quite happy to provide free information; however it will be provided in such a way that it will be safe and accurate, and not affect the function of the appliance. The fact that a few amateurs get lucky in the random button pushing stakes does not imply in any way that this is a correct or safe procedure.

I trust that this is clear.

Hi there,

Looks like I have the exact same model of motor with the same “C9” error. I’ve checked the bushes and they’re right at the end of their life. Should I get the bushes you suggest above or the bushes including holder (if such a thing exists). Is it easy to fit new bushes?

Thanks for any advice,

Jonathan

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

Well, it appears AEG (Zanussi) have changed the spec on the brush on certain motors and the brushes in the link are too narrow for some FHP motors.

Can you post the dimensions of the remainder of the brush please (apart from the length obviously ;)) and I’ll check the correct ones for you 🙂

Dave.

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

OK, here’s all the idents that I can find (requested dimensions at the end):

Like a previous poster, the motor is an FHP with the following identification plate:
UZ 112 G 70 Typ ME 002
1P 083498 350 F2 1050
230/240V 50Hz DC-El.Iskl.B/F
Sach.-Nr. 645 248 850
SBP 645 260 610 ohne Thermos

The only identification on the brushes are L1 embossed on the outside of the plastic casing and PA66-GF25 on the inside ( manufacture date apr 98 ).

The brush has 470NL printed on it and is 12x6mm in cross-section. Bizarrely, one has worn right down and the other has “lots” of life left in it. The motor itself is maybe four/five years old – having been replaced after two years (grrrrr).

Hopefully this is enough to work out what I need!

Thanks muchly, Jonathan

It does thanks, if you order these Hotpoint ones:

They’re exactly the same (I just opened a pack to check) 😀

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

OK, new brushes installed and we’re been happily washing again now. One problem though is the motor is noisier than before. On a machine which used to be “silent” the motor makes quite a loud “clicking” which changes frequency in time with the motor speed.

I’ve already run some emery paper over the copper contacts and chamfered the corners of the brushes as per earlier suggestions.

Any ideas?

Cheers.

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

If brushes are in correct orientation, it maybe damage to motor commutator, ie raised seg/s.
If you can get your finger to touch copper segs as you manually turn motor (Motor not connected to machine) and feel for any imperfections. If any are felt its new motor Im afraid.
Also personally I wouldn’t use any other aid than a comstick on the motor com.

Power off first :plug:

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

So, it *is* one raised commutator 🙁 🙁

Looks like I’ll need a new motor, do you have the part I require?

text on the motor:
UZ 112 G 70 Typ ME 002
1P 083498 350 F2 1050
230/240V 50Hz DC-El.Iskl.B/F
Sach.-Nr. 645 248 850
SBP 645 260 610 ohne Thermos

Secondly, before I got round to taking a look inside, there may be something else broken? When I currently select any program and press start, the *motor* does a short *fast* spin. I’ve had a poke into the PCBs and the one that drives the motor looks like it’s been hot in the past (covered in soot and smells a bit too).

text on the controller:
AKO 546 273
AEG 645 307 080
645 180 700-01

Any tips welcomed!

Jonathan

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

I would imagine motor blown PCB 😥

Greg

[jonathantong]

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

didn’t really want to hear that!

FWIW there are two PCBs, one which looks like it drives the motor only and the other which I presume drives all the other gubbins. Also, if it’s any help, if I select “pump out” the motor spins (when I think it shouldn’t) and the pump DOES NOT run.

So, is this a DIY fix, call out or not-economical-to-repair? The AEG is now about six years old and *should* have plenty more life in it……?

Re: AEG LAVAMAT – CHANGED BRUSHES BUT STILL C9 CODE

If you could post the PNC (product code) of the machine from the rating label inside the door Jonathan (it should begin 9…..), I’ll price the PCB and motor for you but as you say it may turn out to be uneconomical I’m afraid 🙁

Dave.
