Symptoms of a bad Interlock Switch include:

• The dishwasher will not start a cycle even with the door closed  
• Error messages related to the door being open displayed
• Failure to advance through cycle selections

Causes can be normal wear and tear over extended use. Moisture exposure inside the dishwasher environment may also contribute to switch malfunction over time.
