Step-by-step troubleshooting

1. Check Power Supply
   Do: Verify the dishwasher is plugged in and the circuit breaker hasn't tripped.
   Observe: Power indicator lights or sounds return.
   Means: Power issue resolved.
   Next: If power is normal, proceed to next step.
2. Inspect Door Latch
   Do: Close the door firmly and check if the latch engages properly.
   Observe: Door latch clicks or locks securely.
   Means: Door is properly closed.
   Next: If latch is faulty, proceed to next step.
3. Look for Error Codes
   Do: Check the control panel for any displayed error codes.
   Observe: Error code is visible on the display.

4. Reset the Dishwasher
   Do: Unplug the dishwasher for 1 minute or press the reset button if available.
   Observe: Dishwasher powers off and restarts.
   Means: Potential software glitch resolved.
   Next: Test by starting a cycle.
5. Test Water Supply
   Do: Check the water inlet valve for proper operation and ensure the water supply is on.
   Observe: Water flows into the dishwasher when the valve is activated.
   Means: Water supply is functional.
   Next: If no water flow, proceed to next step.
6. Check for Blockages
   Do: Inspect the drain hose and filter for clogs.
   Observe: No visible blockages in the drain hose or filter.
   Means: Drain system is clear.
   Next: If blockage found, clean and test.
7. Test Control Board
   Do: Use a multimeter to test the control board for power and continuity.
   Observe: Multimeter shows correct voltage and continuity.
   Means: Control board is functioning.
   Next: If no power or continuity, proceed to next step.
8. Inspect Motor and Pump
   Do: Check the motor and pump for damage or overheating.
   Observe: Motor and pump appear undamaged and cool to the touch.
   Means: Motor and pump are operational.
   Next: If damaged, replacement is needed.

Common causes

Parts matching

If you need to replace parts, match these common components to your model:

• Door Latch Assembly – If the door doesn't close securely
• Water Inlet Valve – If water isn't entering the dishwasher
• Control Board – If the control panel is unresponsive
• Drain Filter – If clogging is recurring
• Motor/Pump Assembly – If the dishwasher makes no noise when starting

Always refer to your dishwasher's manual for specific part numbers and compatibility.

When to call a professional

• If the dishwasher still won't start after checking all power sources and resetting
• If you detect a burning smell or electrical sparks
• If the control board or motor/pump is damaged and you're not comfortable replacing it
• If error codes persist after troubleshooting
• If water supply issues continue after checking the valve and connections
