Kenmore Dishwasher Error Code F6E6

F6E6 indicates that the dishwasher's control board has detected incoming water temperature below 18°C (65°F). The dishwasher monitors water temperature through a sensor in the inlet circuit, and this code triggers when that reading falls under the minimum threshold. The issue can be caused by a cold water supply, a low water heater setting, or a faulty temperature sensor.

A reset may temporarily clear the code, but it will return if the underlying cause is not corrected. If incoming water temperature remains below 18°C (65°F) or the temperature sensor is still faulty, the control board will detect the fault again during the next fill cycle. Address the root cause before relying on a reset.

If the fix is simply adjusting the water heater temperature or confirming the supply line connection, there is no parts cost involved. If the water temperature sensor or thermistor needs replacement, parts typically range from $15 to $60 depending on the specific model, with professional labor adding $80 to $200 depending on your area and service provider.

Start by confirming the dishwasher is connected to your home's hot water supply line. Run the kitchen sink on hot for about 60 seconds before starting the dishwasher to ensure hot water is already in the line. Verify your water heater is set to approximately 49°C (120°F). If the code persists with adequate hot water supply, the temperature sensor or its wiring circuit should be tested for proper resistance values.

Running the dishwasher with this fault active means it is filling with water that is too cool for effective cleaning and sanitization. Dishes may not be properly cleaned, and detergent may not dissolve or activate correctly. It is best to resolve the water supply or sensor issue before continuing regular use.
