Bosch WAW285H1UC 2.2 cu ft 800 Series Compact Washer Er:22 Error Fix: Temperature Sensor Open / Short

The water temperature sensor (NTC thermistor) has an open or shorted circuit. Check the sensor wiring harness for damage. Measure the sensor resistance — approximately 10K-50K ohms at room temperature (varies by model). An infinite reading indicates an open circuit; a near-zero reading indicates a short. The NTC sensor is typically located in the outer tub near the heating element. Replace the sensor if readings are out of range.
