GE Washer Error Code H20: Water Supply Issue

The Human Verdict: It’s The Valve Assembly

I watched the repair video so you don’t have to. If you’re seeing H20 on your GE washer, it means the machine isn’t detecting water entering the tub. While it could be as simple as your home’s water valves being turned off, it’s usually the Water Inlet Valve Assembly that has failed.

The repair is straightforward but involves removing the top control panel console. The video guide is a bit informal (“clink clack”), but the key takeaway is to be careful with the plastic studs holding the control board—don’t lean on them!

What It Means

The washer attempts to fill for a set time. If the water level sensor doesn’t detect an increase, the computer throws the H20 code to prevent running dry or burning out the pump.

Common Causes

1. Water Taps Closed: Ensure the hot and cold water valves on your wall are fully open.
2. Clogged Screens: The mesh screens inside the valve inlets might be plugged with sediment.
3. Failed Valve Assembly: The solenoids on the valve assembly have burned out or stuck closed.

Step-by-Step Fix

1. Check The Basics

Before buying parts, turn off your water supply, unscrew the hoses from the back of the washer, and check the little mesh screens inside the valve connection points. If they are full of gunk, clean them out. If they are clean and the water is on, you need a new valve.

2. Get The Part

You need the Water Inlet Valve Assembly. This is the “gizmo” mentioned in the video.

3. Remove The Control Panel

1. Power Down: Unplug the washer.
2. Remove Tray: Take out the 5 screws holding the detergent tray/top console area.
3. Lift & Pull: Lift the console up and pull it forward slightly. It might hang a bit (“clink clack”).
4. Access Valve: Lay the console face down (carefully! don’t break the plastic studs). Remove the 3 screws holding the backing pad/cover to expose the valve assembly.

4. Swap The Valve

1. Disconnect: Use pliers to squeeze the clamps and remove the black rubber hoses from the old valve.
2. Unscrew: Remove the 4 screws securing the valve to the washer body.
3. Replace: Put the new valve in, secure it with the 4 screws, and reattach the hoses with the squeeze clamps.
4. Reassemble: Put the cover back on (3 screws), lift the console back into place (watch the alignment grooves!), and secure the final 5 screws.

Note: The video creator warns that the plastic studs holding the components are weak. Do not use the open console as a workbench or lean on it.
