Zanussi AutoSense / ZDH Series Condenser Dryer: Motor drive general malfunction E50; drum drive motor fails to turn or stops unexpectedly during tumble sequence.
On Zanussi (Zanussi AutoSense / ZDH Series Condenser Dryer) 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. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.
