The Latch Bolt is an OEM replacement part for Whirlpool dishwashers. This component is essential for securing the dishwasher door during operation, ensuring that it remains tightly closed to prevent water leaks and allow the dishwasher to run properly. The latch bolt engages with the door latch assembly, creating a secure seal.

Causes of a bad latch bolt can include regular wear and tear, damage from forceful closing of the dishwasher door, or misalignment that affects the latch's engagement.

Symptoms of a bad Latch Bolt include:

• The dishwasher door not staying closed
• Water leaking from the door during operation
• Difficulty in latching or unlatching the door
• The dishwasher not starting because it detects an open door

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
