Worth Repairing 11 Year Old Aeg With E66 Fault And Small Leak?

We have an AEG Lavamat Turbo 16810 Update (914601605/02) that has worked flawlessly from installation 2004 up to yesterday. Now it stopped in the middle of a washing program. I set it to "Drain" program and it emptied, but if you try to start a program again it stops after just a minute or so. The stored error code is E66 (this does not show unless you go in to the menu by keeping buttons pressed and turning to spin).

At the same time that this happened, there was suddenly also a small leak underneath the machine, about 10cm in from the front and 10 cm from the right. Strangely, when pulling out the small grey drain hose next to the filter and opening that, there is NO water at all but the leak still continues until water has emptied from underneath. The filter is clear.

So - E66 is "heating relay fault" and it seems it could be the relay, the PCB or the heating element. In addition, there is the leak. A fixed price repair is quoted as £129 and a new equivalent machine is ~£550.

On the face of it, £129 seems attractive compared to the price of a new machine, but obviously the machine is 10 1/2 years old now.

AEG Lavamat Turbo 16810 Update stopping with E66 and small leak

The problem
AEG Lavamat Turbo 16810 Update (914601605/02) stopped mid-cycle after many years of use. It would drain on the Drain programme, but any new programme stopped after about a minute. Stored fault code was E66. A small leak was also reported from underneath, roughly near the front right area. The filter was clear, and opening the small grey drain hose produced no water while the leak underneath continued until the trapped water had emptied.
Likely cause
E66 was identified by the poster as relating to a heating relay fault, with possible causes suggested as the relay, PCB or heating element. The leak source was not diagnosed in the discussion; a tub hole was mentioned only as an example of a fault that could make repair uneconomic.
What fixed it
The accepted advice was not a technical repair. It was to consider the manufacturer fixed-price repair because it may be worthwhile, especially if an expensive part such as the PCB is needed, but to check the terms carefully in case the machine is judged beyond economic repair and only a call-out or other charge applies. The exact fault and repair were not confirmed.
Checks to try
  • Drain programme emptied the machine
  • Programmes stopped again after about a minute
  • Stored error code E66 retrieved via service/menu access
  • Filter checked and found clear
  • Small grey drain hose opened and no water came out while leak underneath continued

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

One thing to bear in mind is that a new AEG washing machine will not be as well made as the 10-year-old one. But to counterbalance that thought washing machines don't tend to last much longer than 10 years these days as the average life is only about seven years.

If the fixed price repair is through AEG it might be worth giving it a go. I don't like fixed-price repairs but it sounds like you may get a decent deal if it needs a new PCB. Fixed-price repairs work by overcharging the majority of people which subsidises the ones needing more expensive repairs but they often have clauses which allow them to write your machine off and charge you a call out if it's going to cost over a pre-set amount. Some of them even charge the full price if they decide it's going to cost them too much more than the fixed charge - so make sure you read the terms and conditions.

So for example if the leak turned out to be a hole in the tub I doubt very much they would repair it for £129. They will probably tell you it's beyond economic repair. So if considering this repair check their terms and conditions and check what they would charge if they consider it is beyond economic repair.
