GE dishwasher H2O code: low water, not filling enough

The dishwasher did not get enough water during the fill. Usually the water valve under the sink is not fully open or the inlet hose is kinked.

Likely causes

Listed from most to least common.

1. Water supply valve under the sink closed or only partly open
2. Water recently shut off for plumbing work
3. Inlet hose kinked or pinched behind the dishwasher
4. Low water pressure in the home
5. Dishwasher not level, so the water level reads low

How to fix the H2O code

1. 1

   Step 1: Open the water valve fully

   Find the hot water valve under the sink nearest the dishwasher. Turn it counterclockwise until it stops.

2. 2

   Step 2: Check the inlet hose

   Look under the sink for kinks or tight bends in the supply line to the dishwasher. Straighten it if you can reach it.

3. 3

   Step 3: Level the dishwasher

   Place a level inside on the door opening. If it tilts front to back, adjust the leveling legs so water does not pool to one end.

4. 4

   Step 4: Clear the code

   Select a different cycle, then switch back to the one you want and press Start.

You'll need: Flashlight, level.
