Amana Dishwasher F8 Error Code
The temperature sensor (thermistor) is reading incorrectly or has failed.
Common causes
- Faulty thermistor
- Wiring issue
- Loose connection
How to fix it
- Check thermistor resistance at room temperature (should be around 50-80 k ohms).
- Inspect wiring for damage.
⚠ When to call a pro: If resistance is out of range, replace the thermistor; if wiring is fine, control board may be faulty.
