Icemaker

Bosch codesBosch refrigerator codes

Icemaker: Ice production cycle is interrupted (mechanical blockage or icemaker fault).

First step from the service manual

Start icemaker self test and observe if ice tray rotates; check for mechanical blockage, if none replace icemaker.

What 1-1-1 means on a Bosch refrigerator

Error code 1-1-1 on a Bosch refrigerator indicates that the icemaker has experienced an interrupted ice production cycle. This fault is generated when the icemaker control detects that the ice tray has failed to complete its normal rotation sequence, which is required to eject finished ice cubes and reset the tray for the next fill cycle. The icemaker module monitors the movement of the tray through its full rotation arc, and if that movement is blocked or not detected within the expected time window, the unit logs this fault and halts further ice production to prevent component damage.

The two primary failure categories for this code are mechanical blockage and icemaker module failure. Mechanical blockages are the most frequent cause and can result from ice bridging inside the tray, a frozen water fill that has overflowed and locked the tray in place, or a foreign object obstructing the ejector arms or rotation path. These blockages prevent the drive motor inside the icemaker from completing its cycle, triggering the fault.

If no mechanical blockage is present, the fault points to a failed icemaker assembly itself. This includes internal failures of the drive motor, the cycle cam, the thermostat that controls freeze detection, or the control board within the icemaker module. The recommended diagnostic approach is to initiate the icemaker self-test and observe whether the ice tray rotates through its cycle. If the tray does not rotate and no obstruction is found, the icemaker unit requires replacement.

Common causes of 1-1-1

  1. 01

    Ice blockage in the tray or ejector

    Wiring / connection

    Ice can bridge or clump inside the tray or around the ejector arms, physically preventing the tray from rotating. Inspect the tray and ejector mechanism for fused or lodged ice and clear any obstructions before running the self-test.

  2. 02

    Frozen overfill locking the tray

    Wiring / connection

    If the water inlet valve delivered too much water during a fill cycle, the overflow can freeze and bind the tray in place. Look for ice accumulated around the base or sides of the tray that extends beyond the normal fill area.

  3. 03

    Failed icemaker drive motor or internal module

    Part replacement

    If the tray is clear of obstructions but still does not rotate during the self-test, the drive motor or internal cycle cam within the icemaker assembly has likely failed. In this case the entire icemaker unit requires replacement.

  4. 04

    Icemaker thermostat failure

    Part replacement

    The icemaker contains an internal thermostat that signals when the ice has frozen sufficiently to begin the ejection cycle. A failed thermostat can prevent the cycle from initiating, causing the tray rotation to never start and triggering the fault.

  5. 05

    Foreign object obstructing rotation path

    Wiring / connection

    Small items that have fallen into the ice bin area can block the tray's rotation arc or jam the ejector arms. Visually inspect the full rotation path of the tray and remove any obstructions before proceeding with further diagnostics.

Frequently asked questions about 1-1-1

What does 1-1-1 mean on a Bosch refrigerator?
Error code 1-1-1 on a Bosch refrigerator means the icemaker's ice production cycle was interrupted before it could complete. The refrigerator detected that the ice tray did not finish its rotation sequence, which is needed to eject ice and refill for the next batch. The cause is either a mechanical blockage preventing the tray from turning or an internal icemaker component failure. Ice production will remain halted until the issue is resolved.
How do I fix error code 1-1-1 on my Bosch refrigerator?
Start by initiating the icemaker self-test and watching whether the ice tray rotates through its full cycle. If the tray does not move, inspect the tray, ejector arms, and rotation path for any ice buildup, frozen overflow, or foreign objects and clear any blockages you find. If the tray is unobstructed but still fails to rotate during the self-test, the icemaker assembly itself has failed and needs to be replaced. Do not attempt to force the tray manually, as this can damage the drive mechanism.
Is error code 1-1-1 on a Bosch refrigerator a safety concern?
Error code 1-1-1 is not a food safety concern because it only affects the icemaker function and does not impact the refrigerator or freezer temperature control. Your food will remain safely stored while this fault is present. However, you should address the error promptly because a jammed icemaker motor running against a blockage can generate heat and shorten the life of the icemaker components.
Will resetting my Bosch refrigerator clear the 1-1-1 error code?
A reset alone will not permanently clear error code 1-1-1 if the underlying cause has not been resolved. You may be able to temporarily clear the fault by power cycling the refrigerator, but the code will return as soon as the icemaker attempts another production cycle and encounters the same blockage or mechanical failure. The fault must be corrected at the source, either by removing a blockage or replacing the icemaker, before the error will stay cleared.
How much does it cost to repair a Bosch refrigerator showing error code 1-1-1?
If the fault is caused by an ice blockage, the repair may cost nothing beyond your time to clear the obstruction. If the icemaker assembly itself has failed and needs replacement, parts typically range from roughly 80 to 200 dollars depending on the specific model, with professional labor adding another 100 to 200 dollars in most markets. Diagnosing the fault yourself using the icemaker self-test before calling a technician can help you understand whether you are facing a simple blockage or a parts replacement scenario.
