How to Fix / Troubleshooting

Safety first: Unplug the washer before removing the control panel or door lock.

Steps to check and correct:

Confirm door closure: Close the door firmly until you hear the latch click. Check for obstructions around the door seal.
Check for lock indicator: On many IPSO models, a lock icon or LED should light when the door locks. If not, suspect the door lock assembly.
Test Start button: Enter diagnostic mode if available and test button inputs, or use a multimeter to check the Start button contacts on the UI PCB.
Inspect door lock: Test the lock coil and door-closed contacts as described in door lock faults. Replace if defective.
Re-test: After replacing faulty components, power up and attempt to start a cycle. If the issue persists, the main control board may not be recognizing inputs and may need replacement.
