F3E1
Maytag Washer
Severity: ModerateWhat Does This Error Mean?
F3E1 means your Maytag washer's water temperature sensor is not reading correctly. The washer uses this sensor to control wash and rinse temperatures. The cycle may stop until the sensor issue is fixed.
Affected Models
- Maytag MVWB865GW
- Maytag MVWC465HW
- Maytag MVWB835DW
- Maytag Bravos XL
Common Causes
- Faulty or failed water temperature sensor (thermistor)
- Loose wiring connection to the temperature sensor
- Sensor damaged by scale or mineral buildup from hard water
- Control board unable to read the sensor's signal
- Extremely cold inlet water causing an out-of-range reading
How to Fix It
-
Check the water supply temperature.
Very cold water (below 40 F in winter) can trigger false sensor errors. Let the supply warm up slightly if possible.
-
Cancel the cycle and unplug the washer for 1 minute.
A reset clears temporary glitches in the sensor reading.
-
Plug the washer back in and start a warm-water cycle.
If F3E1 clears and does not return, it was likely a temporary reading issue.
-
Run a cleaning cycle to remove mineral buildup from the drum and sensors.
Use a washer cleaner tablet once a month if you have hard water.
-
If the error persists, call a technician to test and replace the thermistor.
The sensor is inexpensive but requires disassembly to access.
When to Call a Professional
If the error appears in normal room-temperature conditions, the sensor likely needs replacing. A technician can confirm with a quick resistance test before ordering parts.
Frequently Asked Questions
What does the temperature sensor do in a washer?
It measures the temperature of the water inside the drum. The washer uses this reading to heat or cool water to the setting you chose.
Can hard water damage the temperature sensor?
Yes — mineral deposits can coat the sensor and cause false readings. Running monthly cleaning cycles helps prevent this buildup.
How much does a washer thermistor cost to replace?
The part itself is usually $15 to $40. With a technician's labor, the total repair is typically $100 to $180.
