This error usually requires removing the dishwasher from the cabinet to access the sump area underneath.
Locate the thermistor (temperature sensor), which is inserted into the sump assembly.
Measure resistance with a multimeter if possible (should be ~11k ohms at room temp); if open or shorted, replace the thermistor.
Ensure wiring connections to the thermistor are tight and free of corrosion.
