The door latch assembly is broken or worn and the dishwasher door will not stay closed or engage the lock.
The door switch fails to signal the control board that the door is closed, so pressing Start does nothing.
A weak or broken spring inside the latch causes the door to release during a wash cycle, flooding the floor.
A stuck switch in the closed position causes the dishwasher to run even when the door is not fully latched, creating a safety hazard.
💡 Pro Tip: Is Your Door Latch Switch the Culprit?
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher door won't latch or stay closed during a cycle
⚠️ Dishwasher does not start after pressing the Start button even though the door feels shut
⚠️ Door latch makes a popping or grinding noise when you push it closed
⚠️ Dishwasher starts running with the door visibly ajar (switch stuck in closed position)
Diagnosis tip: Open the door and manually press the latch tongue with your finger. If you don't hear a firm click, or the dishwasher still won't start after latching, the switch assembly has failed. You can confirm with a multimeter set to continuity — the switch should change state as the latch engages. T20 Torx driver is all you need to access the assembly.
