This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn carbon brushes on universal motor, Faulty motor tachometer sensor, Loose or broken motor wiring harness, Defective motor triac on main PCB

Safety first: Unplug the washer and wait several minutes before accessing internal components.

Step-by-step checks:

Check the belt: Ensure the drive belt is on both pulleys and is not shredded or loose.
Inspect motor brushes: Remove the motor and check carbon brushes. If less than ~1 cm, replace both with compatible Brandt brushes.
Check tachometer: Inspect the tachometer coil and magnet at the rear of the motor for damage. Measure resistance.
Wiring and PCB: Inspect the motor harness for burns or broken wires. Reseat connectors on the main PCB.

Reassemble and run a spin test. If D03 persists, the main PCB triac may be faulty.
