What 3-2-6 means on a Bosch refrigerator
Error code 3-2-6 on a Bosch refrigerator indicates a fault detected in the ice maker's crusher motor. The crusher motor is the component responsible for breaking whole ice cubes into crushed ice before dispensing. When the control system detects that this motor is not operating within expected parameters, whether due to a failure to start, a stall condition, or an open circuit, it logs this code and may disable the crush function or the entire ice dispenser.
The diagnostic process begins with a direct inspection and test of the crusher motor itself. A faulty motor may show signs of physical damage, seized bearings, or an open winding that prevents it from drawing current and completing its rotation cycle. If the motor tests within acceptable operating parameters and no electrical fault is found at the motor terminals, the issue may lie within the ice maker assembly's internal control logic, in which case the full ice maker unit requires replacement.
Common triggers for this fault include a motor that has seized due to ice jamming the crusher mechanism, worn motor windings that cause intermittent or complete failure, and wiring harness issues between the control board and the motor. Because the diagnostic path branches between replacing just the crusher motor or replacing the entire ice maker assembly, accurate component-level testing before ordering parts is important to avoid unnecessary repairs.

Common causes of 3-2-6
- 01
Seized crusher motor due to ice jam
Wiring / connectionIce buildup around the crusher mechanism can physically block the motor, causing it to stall and trigger the fault. Inspect the crusher area for compacted or bridged ice that may be preventing rotation.
- 02
Failed crusher motor windings
Part replacementThe motor's internal windings can open or short over time, preventing the motor from running. Testing the motor for continuity and proper resistance at its terminals will confirm this failure.
- 03
Wiring harness fault between control board and motor
Wiring / connectionA damaged, corroded, or disconnected wire in the harness supplying the crusher motor can interrupt power or signal, mimicking a motor failure. Inspect connectors and wiring for visible damage or poor contact.
- 04
Faulty ice maker assembly control
Part replacementIf the crusher motor itself tests as functional, the fault may originate in the ice maker assembly's internal electronics. In this case, the full ice maker unit requires replacement.
