Why is my dishwasher not starting even though the door is closed?

A common reason is a faulty door latch assembly. The latch contains a switch that signals the dishwasher's control board when the door is securely closed. If this switch fails, the dishwasher will not receive the signal to begin a cycle, preventing it from starting.

Can a bad door latch cause water leaks?

Yes, if the door latch does not properly secure the door, it may not create a tight seal with the tub gasket. This can lead to water leaking from around the door during the wash cycle. A misaligned or broken latch can compromise the door's seal.

Is it difficult to replace a dishwasher door latch?

Replacing a dishwasher door latch is generally considered a moderate difficulty repair. It typically involves disconnecting power, removing the inner door panel to access the latch assembly, disconnecting wires, and securing the new part. Basic hand tools are usually sufficient.
