H20 Supply GE Washer: All You Need To Know

GE washers [General electric washers] are one of the best washing machines in the market.

They are gentle on fabrics they wash and are also efficient in the use of energy and water [H2O Supply]

H2O supply, also known as water supply,  is an essential feature in the workings of a general electric washer. Without adequate water flowing into the water chamber of a GE washer, it cannot perform its functions.

In this article, I’ll tell you about the GE washer error code and how to clear it if it ever pops up.

You’ll learn more about the H2O supply, possible reasons you’d experience low supply, and quick repairs to try on.

What Does the H2O Supply Error Code Mean on A GE Washer?

H2O Supply GE Washer

The H2O supply error code means inadequate water filling in the washer’s water chamber.

Error code is a feature in general electric washers that pops up when the volume of water flow becomes compromised. 

The error code will show up due to some of the following reasons:

  •  Blocked or clogged water inlet valve
  •  Faulty water inlet hoses
  •  Malfunctioning water pressure

Why Is My GE Washer Not Filling Up with Water?

There are many reasons why your GE washer will refuse to fill up water.

Experiencing this can be frustrating, especially when you have more important stuff to do than a dirty pile of laundry. 

Here are possible causes to look out for and quick fixes to get it working as normal:

#1. Water Tap Is Off

The first thing to come into mind when your washer isn’t filling up water is if you switched off the water tap.

The water tap is the gap between the water supply and the machine. When switched off, your washer won’t fill up with water.

#2. Low Pressure from Water Supply

If the water pressure from your water supply is low, your washer will not fill up the water. You’d need to call a plumber to check if you have leaky or clogged pipes.

#3. The Water Inlet Valve is Clogged or Burned Out.

If your water valve is clogged, carefully clean the screens on the two hose fitting ports you’ll find on the water inlet valve.

One possible reason your washer won’t fill up water is if the water inlet valve has burned out.

Here are a few steps to check if your water inlet valve is faulty:

Step 1

Open the washer’s top, front, or back, depending on its model. After referring to the owner’s manual, you’ll know where to spot the valve.

Step 2:

Study the wires connected to the solenoid on the valve for a few minutes.

Doing this is because you’ll need to reconnect them eventually. Carefully remove each wire one after the other from the solenoid.

Step 3:

Get your multimeter ready for this step. After pulling out each wire from the solenoid, test each terminal’s continuity using a multimeter.

You’ll be able to tell that the solenoid is faulty when the indication is zero. If this is so, then you need to replace the valve. 

Here are further steps to take to replace the faulty valve:

  • Unscrew the fasteners gripping unto the valve and disconnect the wires
  • Study the sequence of how the wires are connected or, if possible, take a picture.
  • Disconnect the internal tube connected to the water inlet valve and install the new part.

#4. Malfunctioning or Clogged Water Pressure

A malfunctioning or clogged water pressure can cause your washer to refuse to fill up water.

Here’s how to check if your water pressure is clogged:

  •  Unplug the water from the power supply
  • Look for the tube that connects the water level switch and the bottom of the tub
  • Check and clear out particles of dirt or debris that might be causing a clog at both ends of the tube.
  • Once you’ve done that, plug the washer and test it to see if it fills up water like normal.

Here’s how to check if your water level switch is malfunctioning:

  • Locate and disconnect the wires that run from each terminal of the switch
  • Test for continuity of the terminals in pairs.
  • Touch the probes of terminals one and two, two and three, and three and one.
  • Your results should show that there should be continuity in one pair rather than two. If you discover otherwise, then your switch is faulty and requires replacement.

#5. Faulty Main Control Board

A damaged main control board can affect the washer’s ability to fill water.

If you’ve noticed that your washer’s main control board might be in bad shape, here’s how to do a quick repair:

  • Disconnect your washer from the power supply
  • Remove the screws on the rear control panel using a screwdriver and lift the panel to remove them.
  • Remove the screws around the control assembly cover after removing the control housing, and place the cover aside
  • Take a photo of the control board and how the wires are connected.
  • Unscrew the control assembly off the control housing
  • Separate the old main control board from the display board
  • Place the new control board with the display board and reassemble the washer.

How Do You Fix H2O Supply Error Code On A GE Washer?

If you’ve been getting an error code pop-up on your washer, it’s because there is a restriction in the water supply. 

Here’s how to fix the error code:

Step 1:

Figure out the problem causing the error code to pop up. To figure out the problem, you need to run a test like the T06 pressure switch test to get a diagnosis.

Step 2:

Simultaneously rotate the selection knob and click the power button for about ten seconds—this action switches your washer to test mode.

You can find details on how to run this test in the GE washer user manual.

If the T06 test turns out to be positive, the error code is not due to a problem in the water inlet valve or hoses.

If the error code problem is not from the water inlet valve or hoses, it’s probably from the circuit board or the main water supply.

Once you’ve figured out the problem and proffer a solution, the error code will disappear. General Electric washers are nice brands with great features.
