AEG L11842VIT Washer/Dryer No Power or Lights
My 6 year old Integrated AEG L11842VIT washer dryer has no power or lights on the front. It's installed in a rental property for which I am the landlord. I've checked the usual suspects and have traced 230V power to the main PCB which also holds the rotary switch. I was advised by a local engineer that the door interlock usually causes these symptoms, so I replaced it but still no power or lights. With the old switch, there was open circuit across all 3 connectors, the new switch from e spares has 5 connectors but the plug only fits one way using 3 of the 5 connectors. The new switch has approx 900 ohms across 2 connectors which could be the interlock coil, so I was quite confident that the new switch would fix the problem, however no ... Before I delve into replacing the PCB for £220,is there anything else I am missing. I have physically checked the wires from the interlock plug to the PCB, but not con-checked them yet.
Also, what are your thoughts on the age of the machine at 6 years old, would I be better off buying a new integrated washer/dryer ( AEG £650, or Bosch £950) or repairing the one I have.
Thanks for your help.
best regards

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
AEG L11842VIT washer/dryer completely dead with no lights; replacement chosen over speculative PCB repair
- The problem
- An AEG L11842VIT integrated washer/dryer, about 6 years old, had no power and no lights on the front panel. The owner had traced 230V to the main PCB/control area and had already replaced the door interlock, but the machine remained completely dead.
- Likely cause
- The exact fault was not confirmed. The accepted reply stated a door lock would not normally cause a totally dead machine, and suggested other possible causes such as wiring, suppressor fault, dead control panel or PCB fault. The owner later noted a darkened area and black-looking components on the existing PCB, but this was not confirmed as the cause.
- What fixed it
- The recommended action was not to gamble on an expensive replacement PCB because it might not cure the fault and could require calibration or software setup. The owner decided not to proceed with PCB replacement and replaced the washer/dryer instead.
- Checks to try
- 230V supply traced to the main PCB
- Door interlock replaced
- Wires from the interlock plug to the PCB physically checked
- Old interlock found open circuit across all 3 connectors
- New interlock measured about 900 ohms across 2 connectors
- Parts or tools mentioned
- Door interlock
- Main PCB/control PCB
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello. The door switch (lock) shouldn't normally cause a totally dead washing machine. Normally the lights will operate and control panel display is OK but the programme just won't start if the door isn't closed or the door lock is faulty.
In my opinion it would be crazy to gamble £220 on a new PCB. Apart from some of them needing calibrating, or even software to set them up, there's no guarantee it will fix the fault. The same symptoms could potentially be caused by other things such as wiring or even suppressor fault or control panel going dead etc. If you knew for certain that £220 would fix the fault that would be a different matter but you can't be certain. So it needs an engineer or replacing unless you are prepared to gamble.

Hi Andy, Yes you are right and I have decided to replace the washer/drier. As I was dismantling the front panel to remove the pcb, I was very doubtfull if I could re-assemble it with a new pcb. The existing pcb had a small area that was darker than the rest with a couple of components looking a bit black so it may well be u/s, but as I said I didn't feel confident in getting it back together. Furthermore with you saying it may deed calibrating etc I feel I have done the right thing.
Thanks for your reply earlier
best regards

Yes, far too risky with their ridiculous prices. Most pcbs have black patches on them caused by dirt being attracted to hot sections. It can look very much like burning but if a pcb has genuinely burned it's far less subtle and very clearly damaged.
