Bosch Refrigerator Error Code 3-1-2

The 3-1-2 code on a Bosch refrigerator indicates that the ice maker motor has been detected as faulty. The control board monitors the motor that drives the ice ejection mechanism, and when the motor fails to operate correctly, ice production stops and this code is logged. The first step is to power cycle the appliance. If the code returns, the ice maker assembly requires replacement.

A power cycle reset is the recommended first step and may clear the code if the fault was caused by a transient motor stall or a temporary communication error. However, if the ice maker motor has failed mechanically or electrically, the 3-1-2 code will return after the reset. In that case, resetting alone will not resolve the underlying problem.

Because the ice maker motor is not individually replaceable, the cost centers on a complete ice maker assembly replacement. Parts costs for a Bosch ice maker assembly typically range from around 100 dollars to over 250 dollars depending on the specific model. Professional labor to install the assembly generally adds another 75 to 200 dollars, bringing total repair costs to a range of roughly 175 to 450 dollars or more depending on your location and service provider.

You can perform the first diagnostic step yourself by switching the refrigerator off and back on to see if the fault clears. If the 3-1-2 code returns after the reset, the ice maker assembly needs to be replaced. Because the motor is not separately replaceable, the repair involves swapping out the entire ice maker unit, which is a task many experienced DIYers can handle with basic tools and the correct replacement part.

The 3-1-2 fault is specific to the ice maker motor and does not affect the refrigerator's primary cooling or freezing functions. Your food will remain safely stored while this code is active. However, the ice maker will not produce ice until the fault is resolved, so you should plan to address the repair if ice production is needed.
