The door or hood will not close, and the cycle will not start; E9 is displayed.

Safety first: Disconnect power before adjusting door or hood components.

• Inspect latch alignment: For Insinger door-type or hood-type dishwashers, check that the latch or hood mechanism fully engages the interlock switch. Adjust hinges or latch brackets so the switch actuator is fully depressed when closed.
• Check door switch: Locate the door/hood interlock switch. Test continuity with a multimeter while operating the actuator. Replace the switch if it does not change state reliably.
• Examine actuator and hardware: Look for bent or broken latch arms, worn rollers, or missing screws that prevent full closure. Replace damaged hardware.
• Wiring and control input: Verify that the door switch wiring harness is intact and firmly connected to the control board. If the control does not recognize a closed switch despite proper wiring and a good switch, the input circuit on the control board may be defective.
