Frigidaire Washer E31 — What It Means & How to Fix It
Your Frigidaire front-load washer's control board has lost communication with the water-level pressure sensor, so it can't tell how full the tub is — a reset may clear a glitch, but a persistent E31 is a sensor or wiring repair.
What this code means
E31 is logged when the electronic control stops getting a valid signal from the water-level (pressure) sensor. Without that reading the machine can't safely manage filling, so it halts. It is typically a wiring-harness fault between the sensor and board, or a failed sensor, and appears on digital-display models. There is no DIY repair beyond a reset — the rest is a technician's diagnosis.
Frigidaire's service notes place E31 on digital-display front-load models; non-display machines signal level faults differently. As with all the pressure-sensor codes, confirm against your model's tech sheet, since the sensor and harness layout vary by generation.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Loose or damaged wiring between the pressure sensor and control board | Common | No — technician job |
| Failed water-level pressure sensor | Common | No — technician job |
| Control board fault | Less common | No — technician job |
| One-off communication glitch a reset clears | Occasional | Yes — power reset |
What you can try yourself
- Unplug the washer for five minutes, then restore power to rule out a momentary communication glitch.
- Start a short cycle and watch for E31 to return.
- If it comes back, leave it there — the sensor, its harness, and the board are internal parts that need a technician to test safely.
- Have your model number ready; the fix is usually a pressure-sensor or wiring-harness replacement, occasionally the control board.
When to call a technician
- E31 returns after a power reset.
- The washer won't advance past filling or stops early in the cycle.
- It pairs with overfilling or with the E35 code — get it serviced before running more loads.
Typical professional repair cost: A pressure-sensor or harness repair generally runs $130–$280 with labor; a control board pushes higher.
Frequently asked questions
Can I clean or reset the pressure sensor myself?
You can do a power reset, which clears the occasional glitch. The sensor sits inside the cabinet on low-voltage wiring you can't safely reach without dismantling the machine, so testing or replacing it is a technician's task.
Will my Frigidaire still run with an E31?
Usually not properly — without a water-level reading the control won't risk filling, so it stops. You may get it to start with a reset, but if the sensor link is truly down it will halt again.
Is E31 related to the E35 overfill code?
They are cousins — both involve the water-level pressure sensor. E31 means the board can't talk to the sensor at all; E35 means the sensor is reporting an overfill. A failing sensor can produce either.
Related Frigidaire codes
- Frigidaire Washer E11 Your Frigidaire front-load washer opened its fill valve but the water level didn't rise fast enough and timed out — almost always a restricted supply at the taps, hoses, or inlet screens rather than a dead valve.
- Frigidaire Washer E13 Your Frigidaire front-load washer has detected a leak — either water escaping the outer tub or, just as often, an air leak in the thin hose that lets the pressure sensor read the water level.
- Frigidaire Washer E20 Your Frigidaire front-load washer can't pump the water out, almost always because something is blocking the drain path — the pump filter, the drain hose, or the standpipe — rather than a failed pump.
- Frigidaire Washer E21 Your Frigidaire front-load washer is draining, but too slowly to satisfy the control within its time limit — usually a partial blockage in the pump filter or hose, or a drain pump that is losing strength.
