Bosch Refrigerator Error Code 6-1-3

Error code 6-1-3 indicates that the ice maker's water tank temperature sensor (NTC thermistor) has been detected as faulty by the refrigerator's control system. The sensor is responsible for monitoring the water temperature in the tank that feeds the ice maker. When the sensor signal falls outside expected parameters, the refrigerator logs this code and ice maker operation is typically disrupted.

The refrigerator's main cooling and food preservation functions typically remain operational during a 6-1-3 fault, as the error is specific to the ice maker water tank sensor. However, ice production may stop or become unreliable. It is advisable to address the fault promptly to avoid any secondary issues from the ice maker operating without proper temperature monitoring.

A power reset may temporarily clear the error code from the display, but if the underlying sensor or wiring fault is still present, the code will return once the control system completes its diagnostic cycle. A lasting fix requires identifying and correcting the root cause, whether that is a failed sensor, a damaged harness, or a faulty door electronics board.

A knowledgeable DIYer can start by inspecting the sensor connector for corrosion or loose fit and checking the wiring harness for visible damage. Testing the NTC sensor with a multimeter requires some familiarity with resistance measurements. If the sensor and wiring are intact, replacing the door electronics board is a more advanced repair that some homeowners may prefer to leave to a technician.

If the fix is simply cleaning or reseating a corroded connector, out-of-pocket costs can be minimal. Replacing the NTC sensor itself generally costs in the range of $15 to $60 for the part. If the door electronics board requires replacement, parts alone can range from $80 to $200 or more, with professional labor adding additional cost depending on your location and the service provider.
