Washer shows E45 and may fail to lock or unlock the door reliably.

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

Damaged wiring harness, Partial short in door lock, Failing main PCB driver, Corroded connectors

Safety: Unplug the washer before inspection.

Inspect harness: Follow the cable from the door lock to the control board, looking for crushed or abraded sections. Repair or replace as needed.
Replace door lock: Fit a new lock to eliminate internal shorts that can stress the PCB.
Clean connectors: Use contact cleaner on the lock and PCB connectors if corrosion is visible.

If E45 persists, the main control board is likely damaged and should be replaced professionally.
