The F3 error on your Maytag Washer means the control board isn’t getting a proper reading from the water level sensor (pressure switch). This usually points to a wiring or sensor fault rather than a serious mechanical failure, and many owners can check it themselves before calling a technician.
| Error code | F3 |
|---|---|
| Meaning | Water level pressure switch / sensor fault or bad reading |
| Severity | Medium — washer usually won’t complete a cycle until fixed |
| Time to fix | 15–45 minutes |
| Tools needed | Multimeter, screwdriver (Phillips and flathead) |
What the F3 error means
Maytag washers use a pressure switch (sometimes called a water level sensor) to tell the control board how much water is in the tub. The F3 code appears when the board receives a signal outside the expected range, either because the switch has failed, the sensor tube is blocked, or a wire connection has come loose. It’s related to but distinct from other sensor faults like the Maytag Washer F1 Error Code, which points to the main control board itself.
In most cases this is a fixable issue at home, especially if the cause is a kinked tube or loose connector rather than a failed part.
Common causes
- Faulty or worn pressure switch that no longer sends an accurate signal
- Blocked, kinked, or disconnected air pressure tube leading to the switch
- Loose or corroded wiring connector at the switch or control board
- Small amount of water or debris trapped in the pressure tube
- Control board failure (less common, but possible if other fixes don’t work)
- Overfilled tub triggering an out-of-range pressure reading
How to fix the F3 error
- Unplug the washer: Disconnect power for at least one minute before doing any inspection to avoid electric shock and to reset the control board.
- Locate the pressure switch: Depending on your model, this is usually behind the control panel or accessible from the top of the machine. Check your model’s manual for exact placement.
- Inspect the pressure tube: Look for kinks, cracks, or trapped water in the small hose connecting the tub to the switch. Straighten or clear it, then reconnect firmly.
- Check wiring connections: Make sure the connector at the pressure switch and at the control board is firmly seated and free of corrosion.
- Test the switch with a multimeter: With the washer unplugged, test for continuity across the switch terminals while gently blowing into the tube. No change in reading usually means the switch needs replacing.
- Restart and monitor: Plug the washer back in and run a short cycle to see if the F3 code returns. If it does, and the switch and wiring test fine, the control board may need replacing.
FAQ
Can I keep using my washer with an F3 error?
It’s best not to. The washer may not fill or drain correctly, which can lead to incomplete cycles or water damage over time.
Is the F3 error the same as F2?
No. F3 relates to the water level pressure switch, while the Maytag Washer F2 Error Code usually points to a motor speed sensor fault. They have different causes and fixes.
Do I need a technician to fix this?
Not always. If the cause is a kinked tube or loose wire, most homeowners can fix it themselves in under an hour. If the pressure switch or control board needs replacing, a technician may be safer, especially if you’re not comfortable with basic electrical testing.
