GE Dishwasher Error Codes

GE Dishwasher Error Code: H2O

When your GE dishwasher displays error code H2O, it signifies a water supply issue. Here’s a detailed guide on what this error code means and how to address it:

1. Insufficient or No Water Supply: Error code H2O indicates that your dishwasher is not receiving adequate water or, in some cases, no water at all. This problem typically occurs during the initial water fill phase of the cycle, which operates on a timer.

2. Check Water Pressure: The first step in troubleshooting error code H2O is to inspect your water supply. Ensure that the water pressure in your home is within the required range. If the water pressure is turned off or not high enough, the dishwasher won’t receive the necessary amount of water during the water fill phase.

3. Troubleshooting Water Supply: Here’s how to address the water supply issue:

  • Verify that the water supply to the dishwasher is open and not obstructed.
  • Check for any kinks or blockages in the water supply hose. Straighten the hose if it’s kinked, and remove any obstructions.
  • Inspect the water inlet valve, which is responsible for controlling the flow of water into the dishwasher. Ensure that it is functioning correctly and not clogged with debris.
  • If the water inlet valve is damaged or clogged, consider replacing it with a new one.

4. Ensure Water Pressure: Maintaining the correct water pressure is crucial for the dishwasher’s proper operation. If you find that the water pressure is low in your home, consider addressing any plumbing-related issues to increase the water pressure to an adequate level.
