Kitchenaid Dishwasher Error Code 6-6 or F6E6

If your KitchenAid dishwasher displays the error code 6-6 or F6E6, it indicates an issue with the incoming water temperature being too cold. The dishwasher requires a certain water temperature for optimal performance, and if the temperature falls below the specified range, it can lead to problems in the cleaning and washing cycles.

Possible Causes:

1. Low Water Temperature: The water entering the dishwasher is colder than the recommended range.
2. Faulty Thermistor/OWI (Optical Water Indicator): The sensor responsible for measuring water temperature may be malfunctioning.
3. Electronic Control Board Issue: The dishwasher’s control board, which regulates various functions, might be faulty.

Troubleshooting Steps:

1. Check Water Temperature:

   • Use an accurate thermometer to measure the temperature of the water entering the dishwasher.
   • If the water temperature is below 110 degrees Fahrenheit, inspect your water heater for issues.

2. Inspect the Water Heater:

   • Ensure that the water heater is functioning correctly.
   • If the water heater is the culprit, address any issues or consider adjusting its settings to achieve the desired temperature.

3. Verify Normal Water Temperature:

   • If the water temperature is within the normal range (110 to 120 degrees Fahrenheit), the problem may lie with the thermistor/OWI or the electronic control board.

4. Replace Thermistor/OWI or Electronic Control Board:

   • Consult the dishwasher’s tech sheet for a diagnostic test specific to the thermistor.
   • If the thermistor is found to be defective, replace it.
   • If the issue persists, or if the diagnostic test points to a problem with the electronic control board, consider replacing it.

Addressing the KitchenAid Dishwasher Error Code 6-6 or F6E6 promptly will help restore your dishwasher’s performance and ensure that it operates efficiently for the optimal cleaning of your dishes.
