Bosch Washer Error Code NTC interruption

NTC interruption means the washer's temperature sensor has an open or broken electrical circuit. The NTC thermistor is responsible for sending water temperature readings to the control board. Without this signal, the machine cannot regulate the heater and will stop operation. The fault is confirmed through the Bosch test programme.

You should not continue running the washer while the NTC interruption error is active. Without a functioning temperature sensor, the machine cannot monitor or control water heat, which creates a risk of overheating the water, damaging the heater element, or harming laundry. Stop using the machine until the fault is diagnosed and resolved.

A reset may temporarily clear the error display, but the fault will return as soon as the machine runs the test programme or attempts a wash cycle that requires temperature monitoring. The underlying open circuit in the NTC sensor or its wiring must be physically repaired or the component replaced before the error will stay resolved.

A knowledgeable DIYer can check the wiring connectors and harness for visible damage or loose connections without specialized tools. If the wiring is intact, the NTC thermistor itself will need to be tested and likely replaced, which requires locating the sensor inside the machine and disconnecting it safely. If you are not comfortable working inside an appliance, a qualified technician should handle the repair.

If only the NTC thermistor needs replacement, parts typically cost in the range of $15 to $50 depending on the model. If you hire a technician, total repair costs including labor can range from $80 to $200 or more. Wiring harness repairs or a control board replacement would push costs higher.
