What 1-1-3 means on a Bosch refrigerator
Error code 1-1-3 on a Bosch refrigerator indicates a fault within the ice maker system, specifically that the ice production cycle has been interrupted due to a failure of the ice tray to complete its rotation. During normal operation, the ice tray motor drives the tray through a timed rotational sequence to release formed ice cubes into the storage bin. When the control board detects that this rotation has not completed within the expected window, it logs the 1-1-3 fault and halts the cycle to prevent component damage.
The most direct cause of this code is a mechanical obstruction preventing the tray from rotating freely. Ice buildup around the tray or ejector mechanism, a foreign object in the bin, or a jam caused by misaligned or oversized ice cubes can all physically block rotation. The ice maker motor or its drive gear assembly may also be at fault if the obstruction has been cleared but the code persists.
The recommended first diagnostic step is to run the ice maker self-test mode, which commands the tray to rotate so you can observe its behavior in real time. If the tray does not move at all, inspect for physical blockages first, then evaluate the tray motor and wiring connections. If the tray moves partially but stalls, a stripped gear or worn motor is more likely the root cause. Checking the drive mechanism for wear or damage will help determine whether cleaning and clearing the blockage resolves the issue or whether component replacement is needed.

Common causes of 1-1-3
- 01
Ice buildup around the tray or ejector
Wiring / connectionFrost or fused ice accumulation around the ice tray or ejector arms can physically prevent rotation. Inspect the tray compartment for visible ice bridges or clumping and defrost the area if needed.
- 02
Foreign object or jammed ice cubes
Wiring / connectionOversized, irregularly shaped, or clumped ice cubes can wedge against the tray housing and block rotation. Check the ice bin and tray compartment for any obstruction and remove it before re-testing.
- 03
Worn or stripped tray drive gear
Part replacementThe plastic drive gear that connects the motor to the tray can wear or strip over time, causing the motor to spin without rotating the tray. If the motor runs but the tray does not move, inspect the gear assembly for damage.
- 04
Faulty ice tray motor
Part replacementIf no mechanical obstruction is found and the drive gear is intact, the tray motor itself may have failed. A motor that does not energize during the self-test cycle points to motor failure or a wiring fault at the motor connector.
- 05
Wiring or connector fault at the ice maker
Wiring / connectionA loose, corroded, or damaged wiring harness connection between the control board and the ice maker motor can interrupt the signal needed to drive tray rotation. Inspect connectors for corrosion or backed-out terminals.
