GE Dishwasher Error Code: C7

Error code C7 in your GE dishwasher indicates a potential issue with the water temperature sensor or the electronic control board. Here’s a detailed guide on what this error code means and how to address it:

1. Remove Power and Reset: The first step when encountering error code C7 is to remove power from the dishwasher for approximately 5 minutes. This action is an attempt to reset the electronic control board. Follow these steps:

• Unplug the dishwasher or turn off its power source to ensure it is completely disconnected.
• Wait for about 5 minutes to allow the electronic control board to reset.
• After this period, plug the dishwasher back into power and observe if error code C7 reappears.

2. Check for Loose Wire Connections: If the error code C7 persists after the power reset, it’s time to inspect the water temperature sensor’s wire connections. Loose or faulty connections could be the cause. Here’s what to do:

• Disconnect power to the dishwasher to ensure safety during inspection.
• Access the water temperature sensor and examine its wiring harness. Make sure all connections are secure. If you find any loose or damaged wires, address them accordingly.

3. Replace the Water Temperature Sensor: If the wiring harness is secure and there are no issues with the connections, the next step is to consider replacing the water temperature sensor. A malfunctioning sensor could trigger error code C7.

4. Replace the Electronic Control Board: If, after troubleshooting and replacing the water temperature sensor, the error code C7 persists, it may indicate a problem with the electronic control board. In this case, replacing the electronic control board is necessary.
