Step-by-step troubleshooting
Check Power Supply

Next: If power is restored, proceed to step 2. If not, check the outlet and wiring.
Inspect Door Latch
Do: Check if the door is fully closed and the latch is engaged.
Observe: Door closes securely and latches properly.

Next: Refer to the user manual for the error code meaning and proceed to step 4.
Reset the Dishwasher
Do: Unplug the dishwasher for 1–2 minutes, then plug it back in.
Observe: Dishwasher powers on and functions normally.
Means: A temporary electrical issue was resolved.
Next: If the reset works, use the dishwasher. If not, continue to step 5.
Test the Door Switch
Do: Use a multimeter to test the door switch for continuity when the door is closed.
Observe: Multimeter shows no continuity.
Means: The door switch is faulty.
Next: Replace the door switch if faulty.
Check the Control Board
Do: Inspect the control board for visible damage or burn marks.
Observe: No visible damage on the control board.

Next: If damage is found, contact a professional technician.
Inspect the Water Inlet Valve
Do: Check if the water supply is on and the inlet valve is not clogged.
Observe: Water flows freely to the dishwasher.
Means: The water supply was the issue.
Next: If water is flowing, continue to step 8. If not, clean or replace the inlet valve.
