What is a Washer Door Lock Switch?

The washer door lock switch is a safety mechanism that prevents the washing machine from operating if the door or lid is not securely closed. It’s critical for preventing water leaks and ensuring safe operation during the wash cycle. When this switch fails, your washer may refuse to start or display error codes.

Signs of a Faulty Washer Door Lock Switch

  1. Washer Won’t Start: If your washer fails to start even when plugged in and powered on, the door lock switch might be defective.

  2. Error Codes: Many modern washing machines display error codes related to the door lock when the switch malfunctions.

  3. Door Not Locking or Unlocking: The door may not latch properly, or it might stay locked even after the cycle ends.

  4. Interrupted Cycles: The washer may stop mid-cycle due to a faulty connection in the door lock switch.

Tools and Materials Needed
