Bosch Refrigerator Error Code 3-1-6

Error code 3-1-6 indicates that the ice maker's crusher motor has been detected as faulty. The crusher motor is the component that breaks whole ice cubes into crushed ice for dispensing. The refrigerator's control system was unable to confirm proper operation of this motor, so it logged the fault and may disable the crushed ice function.

Yes, error 3-1-6 is specific to the crusher motor within the ice maker system and does not affect the refrigerator's cooling or food preservation functions. You can continue using the refrigerator normally. However, avoid repeatedly selecting crushed ice mode while the fault is active, as this could stress or further damage the motor or assembly.

A reset may temporarily clear the fault code from the display, but if the underlying crusher motor problem has not been resolved, the code will return once the control board attempts to operate the crusher again. A reset is useful for confirming whether the fault is intermittent, but it is not a fix for a mechanically or electrically failed motor or ice maker assembly.

A knowledgeable DIYer can start by checking for ice jams in the crusher mechanism and clearing any blockages, which sometimes resolves the fault without parts. If a jam is not the issue, testing and replacing the crusher motor or ice maker assembly requires basic electrical testing skills and sourcing the correct replacement parts. If you are not comfortable with appliance electrical work, a certified technician is recommended.

Repair costs vary depending on the root cause. If only the crusher motor needs replacement, parts typically range from around $30 to $100 depending on the model, plus labor if a technician is hired. If the full ice maker assembly requires replacement, parts costs generally range from $100 to $300 or more, with additional labor costs on top of that.
