Step-by-step troubleshooting

Unplug and Reset
Do: Unplug the dishwasher for 1 minute, then plug it back in.
Observe: Check if the lights stabilize and the dishwasher starts.
Means: A reset can clear minor electronic glitches.
Next: If no change, proceed to next step.
Check Door Latch
Do: Ensure the door is fully closed and the latch engages securely.
Observe: Look for a blinking light or error code if the door is not latched.
Means: A faulty door latch prevents the dishwasher from starting.
Next: If the door is closed but not latching, check for damage or debris.
Inspect Power Supply
Do: Verify the circuit breaker hasn't tripped and the outlet is working.
Observe: A tripped breaker or dead outlet means no power to the dishwasher.
Means: Electrical issues prevent the dishwasher from starting.
Next: If power is normal, proceed to next step.
Look for Error Codes
Do: Check the control panel for error codes or symbols.
Observe: Error codes indicate specific issues like a blocked drain or sensor fault.
Means: Error codes help identify the exact problem.
Next: Refer to the owner's manual for code meanings.
Test Control Panel
Do: Press and hold the 'Cancel' or 'Start' button for 3 seconds.
Observe: The display may reset or show a different error.
Means: A stuck button or faulty control panel can cause blinking lights.
Next: If the issue persists, test the control panel with a multimeter.
Check Water Inlet Valve
Do: Ensure the water supply valve is fully open and there's water flow.
Observe: No water flow may trigger a sensor error.
Means: A closed valve or clogged filter can prevent operation.
Next: If water is flowing, proceed to next step.
