Dishwasher does not begin a cycle even when the door is fully closed — the faulty switch fails to signal the control board that the door is secured.
Dishwasher starts a wash cycle then unexpectedly stops, with remaining time flashing on the display and no error code shown.
Dishwasher runs with multiple unexpected pauses or restarts during a single cycle, caused by intermittent contact failure in the door switch.
Appliance behaves as if the door is open while it is physically latched shut, preventing any wash program from completing.
💡 Pro Tip: How to Know Your Door Switch Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher won't start even though the door appears fully closed
⚠️ Cycle starts normally then stops mid-wash with remaining time flashing
⚠️ Dishwasher senses door is open when it is actually latched shut
⚠️ Cycle runs with multiple unexpected interruptions and no error code displayed
🔍 Quick test: Set your multimeter to continuity mode. With the door latch pressed in, the switch should show continuity. If it reads open in both states, the switch is faulty and needs replacement. Always unplug the dishwasher before testing or replacing.
