Signs it has failed

Check before you buy

What replacing it fixes: if the signs above match your washing machine and the checks point to this part, fitting a new one should clear those faults. If the symptoms continue, the cause is elsewhere (a control board, a sensor or a blocked vent or hose).

How to replace it

  1. Unplug the machine
  2. Open the door (use the emergency release if it is stuck) and peel back the front of the door seal if the lock sits behind it
  3. Remove the two or three screws holding the lock
  4. Photograph and unplug the connector, then fit the new lock and reconnect
  5. Refit the seal and test with a short cycle

Guide steps are typical for this type of part. Layouts differ between models, so follow your own manual where it differs.

Getting the right part

Locks vary by connector layout, hook design and delay type. Match the part number from the old lock or your model number.

Check your model number first. It is on the rating plate — usually inside the door frame, on the back or side panel, or inside the appliance. Parts that look identical often differ by model, so match the number to the listing before you order.
