Bosch Refrigerator Error Code 3-1-9

Error code 3-1-9 on a Bosch refrigerator indicates a fault with the ice maker's crusher solenoid. The control board has detected an abnormal electrical condition at this solenoid, which is the component responsible for switching the ice maker between crushed and cubed ice modes. The crushed ice function will typically be disabled until the fault is resolved. Repair involves testing the solenoid and replacing either the solenoid or the full ice maker assembly depending on the diagnosis.

Error code 3-1-9 is not a safety hazard. It is a component-level fault specific to the ice maker's crusher solenoid and does not affect the refrigerator's cooling performance or food safety. Your refrigerator will continue to run normally, though the crushed ice feature may be unavailable until the issue is repaired.

A power reset may temporarily clear the error code from the display, but the code will return if the underlying fault with the crusher solenoid or wiring has not been corrected. Resetting the unit without addressing the cause is not a long-term solution. Proper diagnosis and repair of the solenoid or ice maker assembly is required to permanently resolve the fault.

A knowledgeable DIYer comfortable with basic electrical testing can diagnose this fault by using a multimeter to check solenoid coil resistance and inspecting the wiring harness and connectors for damage or corrosion. If the solenoid tests faulty, replacing it is a straightforward part swap. However, if the diagnosis points to the ice maker assembly, that replacement is more involved and some homeowners prefer to have a technician handle it.

Repair costs vary depending on whether only the solenoid needs replacement or the entire ice maker assembly is required. Solenoid replacement parts typically range from around $20 to $60, while a full ice maker assembly can range from $100 to $300 or more for parts alone. Adding professional labor, total repair costs generally fall between $150 and $450 depending on the extent of the repair and your location.
