Bosch Refrigerator Error Code 3-1-3

Error code 3-1-3 on a Bosch refrigerator indicates a fault with the water fill valve that supplies water to the ice maker. The control board has detected that the valve is not operating correctly, which can stop ice production entirely. The diagnostic process involves testing the valve electrically and mechanically, then replacing it or the ice maker if a fault is confirmed.

The refrigerator's cooling and food preservation functions typically remain unaffected by a 3-1-3 fault, so stored food is not at immediate risk. However, if the water valve is stuck open, there is a risk of water overflowing the ice maker tray and leaking inside the freezer or onto the floor. It is best to address the fault promptly, and if you notice any signs of water leakage, shut off the water supply to the refrigerator until the repair is completed.

Resetting the refrigerator by unplugging it or cycling the power may temporarily clear the displayed code, but if the underlying fault with the water valve or ice maker has not been resolved, the code will return once the appliance runs an ice fill cycle again. A reset is useful for confirming whether the fault is intermittent, but it is not a substitute for proper diagnosis and repair of the faulty component.

A knowledgeable DIYer can perform basic checks such as inspecting the water supply line, verifying the shutoff valve is fully open, and looking for obvious wiring damage. However, testing the solenoid valve for proper continuity and voltage requires a multimeter and some familiarity with appliance wiring. If the valve or ice maker needs replacement, the job is manageable for an experienced DIYer but a technician is recommended if you are not comfortable working with water supply connections and electrical components.

Repair costs vary depending on which component needs replacement. A replacement water fill valve typically costs between $20 and $80 for the part alone, while a full ice maker assembly can range from $80 to $200 or more depending on the model. Adding professional labor, total repair costs generally fall between $100 and $350. Getting a diagnostic visit from a technician first will help confirm which part is at fault before purchasing anything.
