How to fix the issue?

If you encounter the GE Dishwasher H2o error, we have explained a few ways to help you fix the issue.

Check the water supply

The H20 error mostly occurs due to insufficient or no water supply to the dishwasher. Start by ensuring the water supply valve beneath your kitchen sink is fully open. Additionally, check for any kinks or obstructions in the water inlet hose. Straighten out any kinks and remove any blockages that may impede water flow.

Check the water inlet valve

A faulty water inlet valve can prevent water from entering the dishwasher, triggering the H20 error. Locate the valve behind the kickplate at the bottom of the dishwasher. Using a multimeter, test the valve for continuity. If it fails the continuity test, you must replace the water inlet valve.

Clean the water inlet filter

A clogged water inlet filter can hinder water flow and trigger the H20 error. Locate the filter inside the dishwasher, usually at the base of the tub, and remove any debris or sediment. Rinse the filter under running water to remove any stubborn residue.

Examine the water pressure

Inadequate water pressure can also cause the H20 error. Ensure that the water pressure in your home is within the recommended range. Insufficient pressure may require the assistance of a plumber to address any underlying plumbing issues.

Check the dishwasher’s float switch

The float switch, located at the bottom of the dishwasher tub, monitors the water level. If the switch is stuck or malfunctioning, it can prevent the dishwasher from filling with water, resulting in the H20 error. Inspect the float switch for any obstructions or damage. Gently clean or replace the switch if necessary.

Reset the dishwasher

A simple reset can sometimes resolve minor electronic glitches causing the H20 error. Turn off the dishwasher, unplug it from the power source, and leave it disconnected for a few minutes. Reconnect the power and turn on the dishwasher.
