GE Washer Not Filling With Water: Causes and How to Fix It
Updated · from manufacturer service documentation
If a GE washer isn't filling with water as expected, the service diagnostic checks the house water supply valves, the pressure tube, and the water valves themselves — GE's own control logic flags this internally as Fault Code 8, Pressure Sensor Loss. The control compares how much water it calculated it put in against what the pressure sensor actually reports, and a mismatch points to one of a short list of causes.
What Causes a GE Washer to Not Fill
| Cause | Likelihood | DIY difficulty | Related part |
|---|---|---|---|
| House water supply valves not turned on | Most common | Easy — check valves | — |
| Pressure tube pinched where it passes through the top cover grommet | Common | Easy — inspect tube routing | Pressure tube |
| Pressure tube has trapped water, delaying the pressure reading | Common | Easy — check/clear tube | Pressure tube |
| Water valve not operating correctly | Less common | Moderate — Service Mode valve test | Water inlet valve |
| Pressure sensor output doesn't match actual water level | Rare | Pro repair (control board) | Control board |
How to Fix It, Step by Step
-
Check that the house water supply valves are fully on
This is the first documented check for a pressure-sensor mismatch (Fault Code 8) on this platform.
-
Check the pressure tube for pinches
Look specifically where the tube passes through the top cover grommet — a pinch there restricts the pressure reading without any visible water problem.
-
Check the pressure tube for trapped water
Trapped water in the tube can delay or distort the pressure increase the control is expecting to see as the tub fills.
-
Test the water valves directly using Service Mode
In Service Mode, pressing Start toggles the hot water valve (test #6) or cold water valve (test #7) on and off, with a 1-minute timeout — if a valve doesn't audibly click or actually flow water during its test, that valve has failed.
-
Check the pressure sensor's output voltage against the pressure sensor chart
If the output doesn't match the actual water level in the basket, the control itself needs replacing, since the pressure sensor is mounted directly to it.
Which Models This Applies To
Documented for the GE GTW750 (2018) top-load washer's Fault Code table and Service Mode test procedures. Fault Code 8 (Pressure Sensor Loss) is distinct from the platform's Flood Warning codes (6 and 7), which cover the opposite problem — too much water — rather than a fill failure.

Frequently Asked Questions
What does Fault Code 8 mean on a GE washer?
Pressure Sensor Loss — the control detected too great a difference between the water level it calculated it added and what the pressure sensor is actually reporting.
Can I test the water valves myself without a multimeter?
Yes — GE's Service Mode includes a direct valve test: pressing Start toggles the hot or cold water valve on for up to a minute so you can confirm it's actually operating.
Could a pinched tube really stop the washer from filling properly?
Yes — a pinch at the top cover grommet, or trapped water inside the pressure tube, can distort the pressure reading enough that the control thinks something is wrong with the fill even when the valves themselves are fine.
When does a fill problem mean the control board has failed?
Only after supply, tube routing, and valve operation have all tested normal — if the pressure sensor's output still doesn't match the actual water level, the control needs replacing since the sensor is built into it.
