Washer-dryer drum does not spin or tumble; E07 appears during wash or spin phases.

Safety first: Unplug the appliance. Drum and motor components can start unexpectedly if power is present.

• 1. Check for mechanical obstruction: Try to rotate the drum by hand. It should turn smoothly. Grinding or seizure suggests a bearing or foreign object issue rather than an electrical fault.
• 2. Access the motor: Remove the rear panel and drive belt. Inspect the motor and wiring harness for damage or loose connectors.
• 3. Inspect carbon brushes (if applicable): On universal motors, remove the brush holders and check brush length. If brushes are worn to a few millimeters or uneven, replace them as a set.
• 4. Test tachometer sensor: On the motor shaft, locate the tachometer coil. Measure its resistance; an open circuit indicates failure. Ensure the connector is firmly seated.
• 5. Check motor windings: Measure resistance across motor terminals according to service data. Very high or zero readings indicate a defective motor.
• 6. If motor assembly is good: The motor control section of the power module may be faulty. Replacement of the module should be carried out by a qualified technician due to high-voltage circuitry.
