Bosch 00165281 Dishwasher Temperature Sensor with High-Limit Thermistor

Dishwasher Temperature Sensor with High-Limit Thermistor – Bosch

The dishwasher temperature sensor with high-limit thermistor monitors the wash water temperature throughout the cycle and provides the control board with real-time temperature data. This is an NTC (negative temperature coefficient) sensor — its resistance decreases as temperature increases. The high-limit thermistor also acts as a safety device, protecting the dishwasher from overheating. When the sensor fails, the dishwasher may not heat water correctly, may display error codes, or may shut down to prevent damage. This direct-replacement sensor restores accurate temperature monitoring and safety protection.
