Kenmore Washer F10 Error — Water Temperature Too High
The F10 error code on Kenmore washers indicates the water temperature during a wash cycle has exceeded a safe maximum. This is a protective shutdown to prevent damage to clothing fabrics and internal components. It is less common than drain errors but occurs in specific model lines.
Likely Causes
- Thermostat or thermistor reporting inaccurate temperature readings
- Heating element failing in the “on” state and not shutting off
- Hot water supply at an unusually high temperature (over 140°F)
Checking Your Hot Water Supply
Use a thermometer at the nearest hot water tap. If water exceeds 120°F, adjust your water heater thermostat down — this is both a safety measure and will resolve F10 in many cases.
Component Diagnosis
If the supply temperature is normal, test the thermistor resistance at various water temperatures to ensure readings are within specification. An open or short circuit in the thermistor requires replacement. Our certified Kenmore technicians carry thermistors for common Kenmore washer models.
