Bosch Refrigerator Error Code 4-1-1

The 4-1-1 code on a Bosch refrigerator indicates an internal ice maker fault. This means the ice maker assembly has detected a failure within its own internal components or circuitry. The code is specific to the ice maker module and does not indicate a problem with the main refrigerator control board, water line, or freezer temperature. Ice production will stop while this fault is active.

A power cycle reset may clear the 4-1-1 code if the fault was caused by a temporary voltage irregularity or signal glitch. To reset, turn the appliance off and back on. However, if the fault is due to a physical failure inside the ice maker module, such as a failed motor or control board, the code will return after the reset and the ice maker will need to be replaced.

If the ice maker assembly needs to be replaced, part costs typically range from around $100 to $300 depending on the specific Bosch model. If you hire a technician, expect to add $100 to $200 or more for labor, bringing the total repair cost to roughly $200 to $500. A power cycle that resolves the error costs nothing.

The first step you can try yourself is a full power cycle: turn the refrigerator off at the control panel or unplug it, wait a minute, then restore power. If the 4-1-1 code clears and does not return, no further action is needed. If the code comes back, the ice maker assembly needs to be replaced, which is a repair most experienced DIYers can handle but may be better left to a technician if you are unfamiliar with refrigerator disassembly.

No, the 4-1-1 fault is not a safety concern. It is specific to the ice maker module and does not affect the refrigerator or freezer compartment temperatures. Your food will remain safe while this code is active. The only impact is that the ice maker will not produce ice until the fault is resolved.
