How can I troubleshoot and fix the H2O error code appearing on my GE dishwasher?

To troubleshoot and fix the H2O error code on your GE dishwasher, follow these steps: 1. **Check the water supply**: Make sure the water supply to the dishwasher is turned on and that there are no blockages in the water inlet hose. 2. **Inspect the water inlet valve**: The H2O error code may indicate a problem with the water inlet valve.
