Step-by-Step Replacement Guide

  1. Turn Off the Washer

    • Unplug the washing machine or turn off the circuit breaker.
    • Ensure the washer is completely powered down before proceeding.

  2. Locate the Door Lock Switch

    • Open the washer door and inspect the area around the door frame.
    • The door lock mechanism is usually behind the front panel near the latch.

  3. Access the Door Lock Switch

    • Remove the front panel or gasket by unscrewing the screws or clips securing it.
