Bosch Refrigerator Error Code 3-3-4

Error code 3-3-4 on a Bosch refrigerator signals an internal ice maker fault. This means the refrigerator's control system has detected a problem originating inside the ice maker assembly itself. The first step is to power cycle the appliance, and if the fault persists after restarting, the ice maker unit needs to be replaced.

The 3-3-4 fault is specific to the ice maker and does not affect the refrigerator or freezer cooling functions. The rest of the appliance should continue to operate safely and keep food at proper temperatures. However, the ice maker will not produce ice while this fault is active, so you should plan to have it repaired or replaced to restore ice production.

If the fix requires replacing the ice maker assembly, parts alone typically range from roughly $80 to $250 depending on the specific Bosch model. Adding professional labor, the total repair cost generally falls in the range of $150 to $400. If the error clears with a simple power cycle or a reseated harness connection, there may be no parts cost at all.

A power cycle, turning the appliance off and back on, can clear the code if the fault was caused by a temporary glitch in communication between the control board and the ice maker. If the 3-3-4 code returns after the reset, the fault is a genuine internal failure within the ice maker and a reset alone will not resolve it. In that case, the ice maker unit requires replacement.

Start by turning the refrigerator off and unplugging it for a few minutes, then power it back on to see if the code clears. If the code returns, inspect the wiring harness connector at the ice maker to ensure it is fully seated and free of corrosion. If the connection looks sound and the fault persists, the ice maker assembly will need to be replaced, as the internal components are not individually serviceable.
