Re: AEG lavamat L14800 – no start light. Error code E51

Here we are again, almost four years on and same symptoms!
I found this post of mine to remind myself of the issue but this time opted not for the awkward and time consuming task of removing the motor.. I sensed there was a damp issue again, although it’s August, this has been the summer which never was.. With the washer propped up and top removed, I left a fan heater on low setting, directed at the motor but playing through the washer. Two hours later I recovered it all and applied power.. Problem gone!!
I wonder how many brushes and motors get unnecessarily changed when really the washer needs a good drying out?

Re: AEG Electrolux 16830 washer dryer not starting wash

Perhaps there might be some help in my recent topic ‘AEG lavamat L14800 – no start light. Error code E51’ The motor is checked out as part of the initial self test and it would seem that yours is often latching a failure. Resetting seems to sometimes get you a wash when the motor happens to pass, since once running the motor warms and cold failures will clear. I think ‘motor’ since your defect sounds like mine where I didn’t get any obvious errors displayed. I learned to access AEG’s Service Test Procedure.. Perhaps this may work for you? For your model likely that with the Programme Selector in the OFF position, press and hold PREWASH and STAIN (or other two button combinations) and turn the Selector through each position to Delicate Spin. The Display will show any errors logged from each of these stepped tests.
Error codes are fairly consistent across all group products and E51 to E55 are to do with the motor. Best of luck!

Update – fixed!!!
I took the motor out and it looked pretty clean. Its a SOLE type. Removed brushes and observed there’s plenty of life left and both are wearing evenly. Commutator looks fine. Seemed good practice to remove as much brushes soot where I could and I polished the commutator against a paper cloth. The machine lives in an unheated outhouse, sat on a concrete floor. Due to the owner’s illness it hadn’t been used for two weeks before the fault was found. Given the recent weather I thought ‘damp’. I left the motor in an airing cupboard over Christmas and refitted it on my next visit. Fault was cured! Have now sited this machine on a thick rug with a plastic membrane underneath. I suspect damp was previously rising through the floor and permeating the motor during its period of inactivity. Have recommended that this machine is used twice weekly and I feel confident it has many years left!
Conclusion – motor became damp and controlling circuitry detected its change in characteristics (likely high resistance through brushes). This inhibited its start up?

Update..
With the Selector away from Off, the door latch clicks every second when the door is open and the indicator is red. Closing the door latches it. With power disconnected door releases after couple of minutes. Apply power and green start light for 4 seconds then nothing. I can select a program but it won’t start, no green light. Though my initial thought was ‘door latch’ it does seem to be working ok.

From searching web forums I’ve now learned to access AEG’s Service Test Procedure..
….With the Programme Selector in the OFF position, press and hold PREWASH and SOAK buttons and turn the Selector through each position to Short Spin. On each of the first 6 or so positions I get a error code E51 accompanied by ‘beeping’. The other settings appear ‘happy’. At Long Spin its E51 again.

On other AEG models, I read that E51 suggests insulation on motor down, or error codes E50 E51 E52 E53 E54 E55 are to do with the main wash motor open circuit.

Suggestion is to look at the carbon brushes on the motor to see if they look worn, and if so to replace.

I’m now looking for replacement brushes before I tackle this job as the machine is at my estranged wife’s and I want to get everything prepared for my next call. Cuts the hassle if you understand 🙂

Would appreciate confirmation on error E51 from some nice person with a AEG manual.. Thanks!
