Won't Run or Power Up — No power, connection issue, or control problem

What does Won't Run or Power Up mean?

The dishwasher does not respond to controls, has no power, or shows no lights. This is typically a power supply issue, a loose connection, or a faulty user interface or control board.

• No power to the unit (check breaker/fuse)
• Bad connection at the junction box
• Loose connections in power-up circuit or between keypad and control
• Incompatible control board for LCD display models
• Door switch problem
• Faulty user interface or control board
