Frigidaire FFCD2413US 24 in Built-In Dishwasher 60 dBA Er-02 Error Fix: Thermistor/Turbidity Sensor Failure

Error code Er-02 on the Frigidaire FFCD2413US 24 in Built-In Dishwasher 60 dBA means: Thermistor/Turbidity Sensor Failure. The thermistor (temperature sensor) or turbidity sensor has failed. The thermistor monitors water temperature during wash cycles, while the turbidity sensor measures water clarity. Check the wire harness connections to the sensor. Measure the thermistor resistance — it should change proportionally with temperature (typically around 50K ohms at room temperature). Replace the sensor assembly if readings are out of range or the sensor circuit is open/shorted.
