How to Fix H2O Error

This is an informational code, not an error. It means the dishwasher has detected a low water level.
Make sure the water supply valve to the dishwasher is turned on completely.
Check that the inlet hose is not kinked or frozen.
Run the hot water at your kitchen sink for a minute before starting the dishwasher to ensure hot water is readily available.
