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

Disconnected motor harness, Faulty motor control module (if separate), Defective main control PCB, Damaged hall/tacho sensor wiring

Safety: Unplug the washer.

Check motor connector: Remove the rear panel and ensure the motor plug is fully inserted and locked.
Inspect harness: Trace the cable from motor to control board for cuts, burns, or loose connections.
Separate motor module: On some Gram models, a separate motor control module is mounted near the motor. Check its connectors and housing for damage.

If no wiring issues are found, the motor control electronics likely need professional diagnosis and replacement.
