Step-by-step troubleshooting

Check Door Latch
Do: Ensure the door is fully closed and latched.
Observe: Door may not close properly or latch is misaligned.
Means: A faulty door latch prevents the dishwasher from starting.
Next: If the door is closed but the latch doesn't engage, proceed to 'Inspect Door Latch Assembly'.
Inspect Control Panel
Do: Press and release the Start button. Check for any error codes or blinking lights.
Observe: No response or blinking lights indicate a control panel issue.
Means: The control panel may be unresponsive or have a malfunction.
Next: If no response, move to 'Test Power Supply and Circuit Breaker'.
Test Power Supply and Circuit Breaker
Do: Check the circuit breaker for the dishwasher and reset if tripped. Test the outlet with a multimeter.
Observe: Circuit breaker may be tripped or outlet has no power.
Means: Power interruption or faulty wiring can prevent the dishwasher from starting.
Next: If power is stable, proceed to 'Check for Error Codes'.
Check for Error Codes
Do: Look for any error codes on the display or blinking lights. Refer to the owner's manual for code meanings.
Observe: Error code is displayed or specific lights blink in a pattern.
Means: Error codes indicate specific issues that need troubleshooting.
Next: Follow the manual's instructions for the error code or proceed to 'Inspect Door Latch Assembly' if no code is present.
Inspect Door Latch Assembly
Do: Open the dishwasher door and inspect the latch assembly for damage or misalignment. Gently tap the latch with a rubber mallet if needed.
Observe: Latch is damaged, misaligned, or not engaging properly.
Means: A faulty door latch assembly prevents the dishwasher from starting.
Next: If the latch is damaged, replace it. If not, move to 'Check Water Supply Valve'.
Check Water Supply Valve
Do: Ensure the water supply valve under the sink is fully open. Check for kinks in the water supply line.
Observe: Water supply valve is closed or supply line is kinked.
Means: A closed water supply valve or kinked line can prevent the dishwasher from starting.
Next: If the water supply is fine, move to 'Test Control Board'.
Test Control Board
Do: Use a multimeter to test the control board for proper voltage. Check for any visible damage or burn marks.
Observe: Control board has no power or shows visible damage.
Means: A faulty control board may prevent the dishwasher from starting.
Next: If the control board is faulty, replace it. If not, consult a professional technician.
