AEG Fault codes....

Tis quite a way down the list.

Some companies share generic codes like 'Lw', for low water level or 'DL' for Door Lock. This might help, there are other sites when Googling 'make model error codes'.

Hope this helps :)

There is a problem with drainage. Check the drain line connected to the disposal or peatrap. Make sure it is not plugged. Otherwise you can disconnect the drain line and put a wet vac on it to try to clear the hose

i20 error code means:
Water is not pumped off and could be:

• Fault with discharge pump

• Discharge pump deenergized (faulty wiring or no activation by electronics)

• Obstruction/blocking (filters in the appliance, discharge opening in discharge trough, discharge pump, discharge hose, siphon, cover plug at siphon connection not removed during first commissioning)

• Discharge hose bent or connection height above 100cm

• Ball valve in discharge trough glued / blocked (discharge pump does not aerate)

or water level inside appliance is not detected and than
could be:

• Pressure controller faulty

• Pressure controller hose obstructed or bent

• Insulation fault with heating element

Drain error?
clear blockage from pump/pipe/s-bend spigot
>> call a service agent

On my AEG Lavamat 62810, when I turn on a wash cycle a motor (pump?) runs for 10–20 seconds then the machine switches off, with no error message. When this happened a few weeks agao running a drain cycle seemed to cure it; now the same thing happens on spin/drain/rinse cycles too. Any ideas?

The motor opening some air valve is probably stuck. See "AEG “micromat_combi 635” halts with error E14. What to do?" at http://appliancewiz.com/questions/47/aeg-micromatcombi-635-halts-with-error-e14-what-to-do for some images and instructions.

This is worth posting in case anyone else has the problem. The mechanic was stumped and then around 3 days later a Zanussi gave the same problem - steam emitting from the drum. He changed the valve - the entire unit. Problem solved. Zanussi and AEG have identical internals. He changed our valve - problem solved.

On 40c wash hit E20 error so moved programme onto long spin and all ok!
