Key Takeaways:

  • The F2 error code on LG dishwashers indicates thermistor or wire harness issues. Follow our step-by-step guide to troubleshoot and fix the error, ensuring your dishwasher runs smoothly once again.
  • After resolving the F2 error, maintain your LG dishwasher by cleaning filters, loading dishes properly, using the right detergent, and ensuring hot water supply. These simple steps can prevent future F2 errors and keep your dishwasher in top condition.

What is the F2 Error Code?

The F2 error code is a common issue that can occur on LG dishwashers. It is often related to two specific components: the thermistor or the wire harness. The thermistor is a temperature sensor that helps regulate the dishwasher’s heating system, while the wire harness connects various parts of the dishwasher, including the thermistor, to the control board.

How to Fix the F2 Error Code

  • Step 1: Start by unplugging the dishwasher or turning off its circuit breaker. Safety first!
  • Step 2: Open the dishwasher door and locate the thermistor, which is usually mounted on the tub or under the heating element.
  • Step 3: Check the thermistor for any visible damage, such as cracks or loose connections. If you notice any issues, it’s likely that the thermistor needs to be replaced.
  • Step 4: If the thermistor appears to be in good condition, it’s time to inspect the wire harness. Take a close look at the wires and connections for any signs of damage or disconnection.
  • Step 5: If you find any damage or loose wires in the harness, it’s best to replace the entire wire harness to ensure a proper connection.
  • Step 6: If both the thermistor and wire harness are in good condition, the error may be due to a faulty control board. In this case, we recommend contacting a professional technician to diagnose and repair the issue.

Check the drain hose for any clogs or kinks, and ensure it is properly installed. Also, clean the filter and check for any debris in the sump area. If the issue persists, consider contacting a professional for further assistance.

Preventing Future F2 Errors

Now that you’ve fixed the F2 error code, you’ll want to ensure it doesn’t happen again in the future. Here are a few tips to keep your LG dishwasher running smoothly:

  1. Regular Cleaning: Clean the filter and spray arms regularly to prevent any blockages that could affect the dishwasher’s performance.
  2. Proper Loading: Make sure to load the dishwasher correctly, avoiding overcrowding and ensuring that no items block the spray arms.
  3. Use the Right Detergent: Choose a dishwasher detergent that is specifically designed for your dishwasher model to prevent any excessive suds or residue buildup.
  4. Maintain Water Temperature: Ensure that your dishwasher has access to hot water by checking your water heater’s settings. Hot water helps the dishwasher clean efficiently.

By following these simple maintenance tips, you can minimize the chances of encountering the F2 error code or any other issues with your LG dishwasher.

Remember, if you’re ever uncertain about any repairs or diagnostic procedures, it’s best to consult a certified technician to avoid any potential damage or injury. Now go forth and enjoy your clean, sparkling dishes without the pesky F2 error code haunting you!
