Resolving GE Dishwasher Error C3

If you own a GE dishwasher, you might have encountered the dreaded C3 error code at some point. This error code indicates a problem with the water temperature sensor, and it can prevent your dishwasher from functioning properly. However, there are a few troubleshooting steps you can take to resolve this issue on your own.

Step 1: Check the Water Temperature

The first thing you should do when encountering the C3 error on your GE dishwasher is to check the water temperature. Make sure that your hot water supply is running at the appropriate temperature, ideally around 120°F (49°C). If the water temperature is too low, it can trigger the C3 error code. Adjust the temperature accordingly and try running the dishwasher again.

Step 2: Inspect the Water Inlet Valve

If the water temperature is not the issue, the next step is to inspect the water inlet valve. The water inlet valve is responsible for allowing water to flow into the dishwasher. It is located behind the lower kickplate panel. Check for any signs of damage or blockage. Clean the valve if necessary or replace it if damaged. Restart the dishwasher to see if the C3 error code has been resolved.

Step 3: Test the Temperature Sensor

If the C3 error code persists, it's possible that the temperature sensor itself is faulty. To test the sensor, you will need a multimeter. Open the dishwasher door and locate the sensor, which is usually situated near the bottom of the tub. Disconnect the wiring harness from the sensor and use the multimeter to check its resistance. Consult the dishwasher's manual or the GE website to find the appropriate resistance value for your model. If the sensor's resistance does not match the specified value, it is likely defective and should be replaced.

Step 4: Call for Professional Assistance

If you have followed all the above steps and the C3 error code still persists, it's best to seek professional assistance. There may be underlying issues that require the expertise of a certified technician. Contact GE's customer service or schedule a visit from an authorized service partner. They will be able to diagnose the problem accurately and provide you with the necessary solution.

In conclusion, the GE dishwasher error C3 is typically related to the water temperature sensor. By checking the water temperature, inspecting the water inlet valve, testing the temperature sensor, and seeking professional help if needed, you can resolve this error code and get your dishwasher back in working order with minimal hassle.
