AEG Lavatherm / SensiDry / AbsoluteCare Heat-Pump: Motor drive general malfunction E50; drum drive motor fails to turn or stops unexpectedly during tumble sequence.
On AEG (AEG Lavatherm / SensiDry / AbsoluteCare Heat-Pump) models: Motor run capacitor degraded (nominal 7–10 μF), defective motor windings (main ~18–25 Ω, aux ~22–30 Ω), open thermal cut-out, or drive triac failure.
Measure motor run capacitor with capacitance meter (must read within ±5% of rating). Check winding resistances with ohmmeter. Rotate selector to 12 o'clock (OFF), press and hold Start/Pause and Exit simultaneously for 4 seconds until the diagnostic LED sequence resets error memory.
