Likely Causes
  1. NTC thermistor has failed open circuit (infinite resistance) or shorted (near zero resistance)
  2. Thermistor wiring has been damaged by heat or steam exposure inside the dishwasher
  3. Thermistor connector pins are corroded from the humid dishwasher environment
  4. Thermistor has become physically dislodged from its mounting in the sump
How to Fix It
1
Disconnect power and access the thermistor, typically located in the sump area or attached to the tub
2
Disconnect the thermistor and measure its resistance (should be approximately 50k ohms at room temperature; 0 or infinite indicates failure)
3
Check the thermistor mounting to ensure it is securely positioned in the sump for accurate water temperature measurement
4
Inspect the connector and wiring for corrosion, moisture intrusion, or heat damage
5
Replace the thermistor if the resistance reading is out of specification

This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
