Common Symptoms & Causes

If your GE Profile PFW940SSPVS is experiencing a steam presoak failure, you may notice one or more of the following signs before or during a wash cycle.

The washer displays error code “E72” or “E75” during the steam presoak phase
Steam presoak option is selected but no steam or moisture enters the drum
The cycle stalls or pauses indefinitely at the presoak stage without progressing
You hear the steam valve clicking repeatedly but the drum remains dry and cold

These issues are most commonly caused by a faulty steam generator, a failed steam inlet valve, or a clogged water supply line restricting water flow to the steam system.

Safety First

Unplug the washing machine from the power outlet before starting any repair — never work on a live appliance.
Shut off the water supply valve before disconnecting any water lines or hoses.
Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
Take photos with your phone before disconnecting any wiring harnesses or connectors.
Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

Before disassembling anything, run a descale procedure to clear mineral buildup, which causes roughly 70% of steam presoak failures by blocking the steam generator’s output. Fill the detergent cup with 1 cup of white vinegar, select the Steam cycle, and run it to completion. If steam function restores after this, no further repair is needed.

Step 2

If descaling didn’t resolve the issue, you need to physically access the steam generator to inspect and test its components. Remove the top panel by backing out the 2 rear Phillips screws, then lift the panel off — the steam generator is the small aluminum heater tank mounted near the top of the tub. Always unplug the machine from the wall before removing any panels to avoid shock risk.

Step 3

Test the heater element inside the steam generator to determine if it has failed open, which would prevent the water from ever converting to steam. Disconnect the 2-pin harness and measure resistance on Rx1 — a healthy element reads 15–40Ω. A reading of OL or open circuit means the element has burned out and the entire generator assembly must be replaced.

Step 4

Test the steam inlet solenoid valve, which controls water flow into the generator — if it fails open-circuit, no water enters and no steam is produced. With the valve’s connector unplugged, measure resistance on Rx1; target range is 200–500Ω. An open reading confirms a failed solenoid; replace the valve before reassembling.

Step 5

Test the NTC thermistor mounted on the generator, which the control board uses to monitor steam temperature — a faulty thermistor causes the board to misread conditions and abort the steam presoak cycle as a safety precaution. At 25°C (77°F) ambient temperature, a good thermistor reads approximately 11kΩ. A reading significantly outside this value means the thermistor is out of spec and should be replaced to restore accurate temperature feedback.

Step 6

After completing your repair, reconnect everything, reinstall the top panel, and plug the machine back in. Run a full Steam Presoak cycle with an actual load inside, and watch through the door glass during the preheat phase — you should see visible steam accumulating inside the drum. No visible steam during preheat confirms the issue is not yet resolved and further diagnosis is needed.

When to Call a Professional

If the issue persists after completing all steps above, the problem may involve the sealed refrigerant system, a failed main control board, or wiring that requires specialized diagnostic equipment. Contact a licensed appliance technician — attempting sealed-system repairs without EPA 608 certification is illegal and unsafe.

Frequently Asked Questions

Why is the steam presoak function not working on my GE Profile PFW940SSPVS?

Steam presoak failure is most commonly caused by a faulty steam generator, a clogged water inlet valve, or a failed thermistor. Check these components first before assuming a control board issue.

Can I repair the steam presoak failure myself, or do I need a technician?

Many homeowners can replace the water inlet valve or steam generator with basic tools and the correct replacement part. However, if the control board is faulty, professional service is recommended.

How do I know if the steam generator needs to be replaced on the PFW940SSPVS?

Use a multimeter to test the steam generator for continuity — a reading of no continuity confirms it has failed and requires replacement. Always unplug the washer before testing any components.
