- With caution
What the washer is detecting
A thermistor in the water inlet changes resistance with temperature. If the control reads a value that could only come from a broken or shorted sensor circuit, it stores F3E2 and may fall back to default temperatures.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A failed inlet temperature sensor (thermistor).
- Possible A loose connector or damaged wire between the sensor and the main control.
Safe checks you can make
- Unplug the washer for one minute, plug it back in and start a new cycle. If the code comes straight back, the condition is persistent and needs diagnosis.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Runs the temperature sensor test.
- Checks the sensor harness and connection at the main control.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Washer water temperature sensor replacement | $180–$310 | Light |
| Washer main control board replacement | $300–$720 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The washer can usually still wash, but water temperature control may be off. Schedule a repair.

Repair or replace?
A fault code alone rarely justifies replacing a washer. Most F3E2 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 10–13-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
