Description

This door switch is the dishwasher door latch interlock that tells the control when the door is closed so cycles can start and run safely. It replaces a worn or failed door switch to restore normal door-sensing operation. What it does:

• Detects when the dishwasher door is fully closed and signals the control to start or continue a cycle
• Prevents the dishwasher from running with the door open (safety interlock function)
• Commonly replaced for symptoms such as dishwasher not starting, stopping mid-cycle, or no response when the door is closed
• Works as the electrical contact/switch portion of the door latch assembly

What's included:

• One dishwasher door switch

Install notes:

• Disconnect power to the appliance before attempting any repair to avoid electrical shock
• Access typically requires removing the inner door panel or latch housing; handle panels and fasteners carefully to avoid damage
• Verify connector orientation and secure wiring harness to the new switch; test door operation before reassembling fully
