This thermistor is the dishwasher's temperature sensor. It reports water temperature to the control so the heater and cycle timing are managed correctly, helping restore reliable wash performance and more consistent drying.

• Monitors water temperature in the tub/sump and sends readings to the control board
• Helps the control regulate heater operation and determine cycle progress/timing
• Failure can result in no heat or poor drying
• May cause unusually long/short cycles or temperature-related fault codes

• Disconnect power at the breaker and shut off the water supply before servicing
• Access is typically from the toe-kick/base area or sump; remove the lower access panel as needed
• Release the locking tab/clip, remove the sensor, and ensure the existing seal/O-ring is properly seated; install the new sensor fully to prevent leaks
