Maytag Dishwasher F3E1 Error Code
The temperature sensor is reading incorrectly, affecting wash cycles.
Common causes
- Faulty thermistor
- Loose connection to thermistor
- Wiring short or open
- Control board failure
How to fix it
- Check continuity of thermistor (resistance should change with temp).
- Reconnect or replace the thermistor wiring harness.
- Use a multimeter to test thermistor at room temp (approx 10k ohms).
⚠ When to call a pro: If thermistor tests bad, replace it; if check out good, the control board may need service.
