OEM dishwasher door switch/interlock switch that detects when the dishwasher door is closed and permits operation.

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishwasher stops intermittently during a cycle when door-switch contact is lost.
• Start or resume operation may fail when the door is closed and latched.
• Dishwasher may respond as though the door is open despite appearing closed.

Check Before Replacing

• With electrical power disconnected, inspect that the door latch mechanically actuates the switch and that the switch is seated correctly.
• With power disconnected, inspect the switch connector and nearby wiring for loose, damaged, or pulled-out terminals.
• Check whether gently applying normal closing pressure to the door changes the symptom; this can indicate inconsistent latch or switch engagement but does not by itself confirm switch failure.
• If qualified to perform appliance electrical testing, check switch continuity only with the dishwasher disconnected from power and using the model-specific technical documentation; replace the switch only if testing identifies it as defective.
