Dishwasher 46

A dishwasher is an essential kitchen appliance that makes our daily chores easier. However, like any other appliance, it may require occasional adjustments to function optimally. One such common issue with LG dishwashers is the door latch. If you are facing problems with your LG dishwasher door latch, this comprehensive guide will take you through the process of adjusting it.


To adjust an LG dishwasher door latch, first inspect the interior of the dishwasher for any obstructions. Adjust the leveling feet if necessary, and shake the door side to side to check for distortion. Inspect the latch and strike plate for obstructions or damage, and clean them out if needed. If the door still doesn’t close properly, you may need to replace the door latch. Always remember to disconnect power before starting any repairs.

Understanding the Function of the Door Latch

The door latch in an LG dishwasher plays a crucial role in securing the door during operation, ensuring that it remains closed throughout the washing cycle. When the door is fully closed, a switch inside the latch allows the control to send voltage to an inlet valve solenoid, which opens the valve and allows the proper amount of water into the tub to start the wash cycle. A defective door latch may prevent the dishwasher from running even with the door fully closed.

Signs That Indicate a Need for Adjustment

There are a few common signs that indicate a need to adjust the LG dishwasher door latch:

  1. Dishwasher not starting: This could be due to the dishwasher not recognizing that the door is closed, preventing it from starting.
  2. Door not closing properly: Obstructions in the latch or strike plate on the chassis can prevent the door from closing.
  3. Misaligned or damaged door seal: This can cause the door to have trouble latching.
  4. Door latch not engaging: If the door is not closed correctly with the door latch engaged, the dishwasher’s safety feature will prevent it from operating.

Tools Required for Adjustment

To adjust the LG dishwasher door latch, you will need a Phillips screwdriver and possibly pliers to help disconnect wires from the latch.
