Dishwasher Error Codes: Troubleshooting Guide

Quick answer

Check your dishwasher's manual to identify the error code. Common codes like F1, F2, or OE indicate issues with water supply, drainage, or heating. Reset the dishwasher by turning it off and on again.

Confirm the symptom

• Dishwasher displays an error code on the control panel
• Dishwasher stops mid-cycle or won't start
• Error code is accompanied by unusual noises or leaks

Tools and prep

• User manual for the dishwasher model
• Screwdriver set
• Multimeter for testing electrical components
• Flashlight for inspecting internal parts
• Bucket for water collection (if leakage is suspected)
• Turn off power at the circuit breaker for safety

Step-by-step troubleshooting

1. Identify the Error Code
   Do: Locate and note the error code displayed on the control panel.
   Observe: Error code is visible and consistent.
   Means: The code helps identify the specific issue.
   Next: Consult the manual for the code's meaning.
2. Check Water Supply and Drainage
   Do: Ensure the water supply valve is fully open and the drain hose is clear of clogs.
   Observe: Water flows freely into and out of the dishwasher.
   Means: No blockage in supply or drainage.
   Next: If the issue persists, proceed to the next step.
3. Reset the Dishwasher
   Do: Turn off the power at the circuit breaker for 1–2 minutes, then restore power.
   Observe: Dishwasher resets and error code clears.
   Means: The reset resolved a temporary glitch.
   Next: Run a test cycle to confirm the issue is resolved.
4. Inspect the Door Latch
   Do: Check if the door latch is engaging properly and closing securely.
   Observe: Door closes without gaps and the latch clicks into place.
   Means: A faulty latch can trigger error codes.
   Next: If the latch is faulty, proceed to the next step.
5. Test the Water Inlet Valve
   Do: Use a multimeter to test the water inlet valve for continuity.
   Observe: The valve shows proper continuity or is defective.
   Means: A faulty valve may prevent water from entering.
   Next: Replace the valve if it's defective.
6. Check the Drain Pump
   Do: Inspect the drain pump for blockages or damage.
   Observe: Drain pump is clear and functioning properly.
   Means: A clogged or faulty pump can cause drainage issues.
   Next: Clean or replace the drain pump as needed.
7. Examine the Control Board
   Do: Look for signs of damage, corrosion, or loose connections on the control board.
   Observe: Control board appears intact with no visible damage.
   Means: A damaged control board may require professional repair.
   Next: If the board is damaged, contact a professional technician.
