Understanding the Kenmore Dishwasher F10 Error Code
The F10 error code on your Kenmore dishwasher signals that the water temperature has exceeded safe operating limits during a wash or rinse cycle. When the control board detects temperatures above the designed threshold, it halts the cycle to protect both the appliance and your dishes from heat damage.
What Causes the F10 Error?
The F10 error typically occurs when the heating element is malfunctioning and staying energized longer than it should, or when the thermistor (temperature sensor) provides an inaccurate reading. Limescale buildup on the heating element can also cause uneven heat distribution and false temperature spikes.
Symptoms to Watch For
- Dishwasher stops mid-cycle with F10 displayed
- Dishes are extremely hot or show heat damage after wash
- Steam releasing excessively from door vents
- Cycle takes much longer than normal before stopping
Step-by-Step Troubleshooting
- Cancel the cycle and let the dishwasher cool for 30 minutes with the door slightly ajar.
- Run a diagnostic cycle: press Heated Dry + Normal simultaneously five times.
- Check the thermistor: it should read approximately 50,000 ohms at room temperature. Replace if outside range.
- Inspect the heating element for visible burning, cracks, or limescale buildup.
- Clean the element with citric acid descaler if buildup is present.
When to Call a Technician
If the F10 error persists after cleaning and a thermistor check, the heating element or control board likely needs replacement. Our certified Kenmore technicians carry genuine OEM parts and can diagnose the exact component causing overheating, typically completing the repair in a single visit with a 90-day warranty.
