E31

Pressure Sensor Fault

Severity

Medium

Seeing E31 on your GE Washing Machine display means the appliance self-diagnostic detected "Pressure Sensor Fault". Before calling a technician, work through the steps in this guide — the fix is often simpler than you think.

Owner's Summary

The water level sensor in your GE washer is giving incorrect readings. Before buying parts, check the thin plastic hose connecting the sensor to the drum — a clog in this hose is the most common cause and costs nothing to fix.

Symptoms

GE washer overfilling or underfilling, inconsistent cycle behavior, E31 error

Common Causes

Defective water level pressure sensor
Blocked or kinked pressure sensor hose
Air leak in sensor chamber
Main board not reading sensor correctly

How to Fix

1 Inspect pressure sensor hose for kinks, cracks or disconnection
2 Blow gently through hose to clear obstruction
3 Test pressure sensor with multimeter
4 Replace pressure sensor if readings are unstable
5 Replace main control board as last resort

Tools You'll Need

These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.

Technical Explanation

GE uses a frequency-based pressure transducer that outputs a variable frequency signal proportional to drum water level. E31 is generated when the board's frequency measurement circuitry receives a signal outside the valid operating range, indicating sensor failure or a disconnected hose.

Is It Safe to Keep Using?

Monitor the drum fill carefully. If the machine overfills, immediately shut off the water supply valves to prevent flooding.

Technician's Pro Tip

The pressure sensor hose connection at the drum tub is a common failure point — the plastic nipple can crack from age. If the hose pulls off the tub fitting too easily or shows cracking, replace the hose before the sensor itself.
