Washer-dryer stops mid-cycle; drum does not turn and E06 appears.

Safety first: Unplug the appliance. Be careful of sharp edges when accessing the motor.

• Check drum movement: Rotate the drum by hand. It should turn smoothly without grinding or binding. Heavy resistance may indicate bearing or mechanical issues rather than an electrical motor fault.
• Access motor: Remove the rear panel. Locate the drive motor at the bottom of the tub. Disconnect the wiring plug.
• Inspect brushes (if fitted): On brushed motors, remove the brush holders and check the length of the carbon brushes. If they are worn to less than ~1 cm or uneven, replace both brushes with Grundig-compatible parts.
• Test windings and tacho: Use a multimeter to measure resistance of the motor windings and the tachometer coil. Compare with service data; open or shorted readings indicate a faulty motor.
• Check wiring to PCB: Inspect the harness from motor to main control board for damage or loose connectors.
• Replace components: Replace worn brushes or the complete motor if windings/tacho are defective. If the motor tests good but E06 persists, the motor control circuit on the PCB may need replacement.
