Bosch Refrigerator Error Code 2-2-1

Error code 2-2-1 on a Bosch refrigerator signals a sensor fault within the ice maker unit. The ice maker contains an integrated temperature sensor that the control board monitors continuously. When that sensor produces a reading outside its acceptable range, or no reading at all, the 2-2-1 code is triggered and ice production may stop. Because the sensor is built into the ice maker assembly, it cannot be replaced on its own.

The refrigerator's cooling system for fresh food and freezer compartments typically continues to operate normally during a 2-2-1 fault, so food safety is generally not an immediate concern. However, the ice maker may stop producing ice until the fault is resolved. It is best to address the issue promptly to avoid extended disruption to ice production and to prevent any underlying wiring issue from worsening.

If only a power reset or a wiring connector reseating is needed, there may be no parts cost at all. If the ice maker assembly must be replaced, parts alone typically range from $80 to $250 depending on the specific Bosch model. Adding professional labor, most repair visits run between $150 and $400 in total, though prices vary by region and service provider.

A power reset is always the recommended first step for a 2-2-1 fault. Turn the refrigerator off, wait a few minutes, and turn it back on to allow the control board to re-initialize. If the error clears and does not return, a transient glitch was likely the cause. If the code comes back after the reset, a physical component failure is present and the ice maker assembly will need to be replaced.

No. The temperature sensor that triggers the 2-2-1 code is integrated directly into the ice maker module and is not available as a standalone replacement part. If the fault persists after a power cycle and the wiring connections are confirmed to be secure and undamaged, the complete ice maker assembly must be replaced to resolve the error.
