Aeg L-72850M Error E52. Motor Makes Noise And Refuse To Move

Hello. On many AEG/Electrolux machines, E52 is commonly linked to the motor feedback/tacho circuit, but it can also be caused by the motor control board or wiring rather than the motor itself. The “hums but won’t turn” symptom is useful.

Before doing anything internal, isolate the washing machine from the mains.

1. Check the motor brushes first If this is the original motor, worn carbon brushes are a very common cause. Remove and inspect both brushes. If they are short, chipped, sticking in the holders, or not making good contact with the commutator, the motor may buzz and fail to turn.

2. Inspect the commutator Look at the copper segments on the motor armature. If they are badly burnt, blackened, rough, or uneven, the motor may not run properly even if the brushes are present.

3. Recheck the tacho coil and magnet Your 180 ohms across the tacho sounds plausible, and seeing a small voltage when spinning by hand is encouraging. Also make sure the tacho magnet on the motor shaft is secure and not cracked or loose.

4. Check the wiring loom carefully Trace the wiring from motor to control board. Look for damaged plugs, loose pins, corrosion, or broken wires, especially where the loom flexes.

5. Suspect the motor control/inverter board If brushes, commutator, tacho, and wiring all check out, the next likely cause is the motor control electronics. A failed triac/driver or dry joint can give this exact fault.

If you post whether this motor has carbon brushes and their condition, that would narrow it down quickly. For mains testing on live circuits or control board repair, it’s best to use a qualified appliance engineer.
