Bosch Refrigerator Error Code 3-4-6
Ice maker
What the 3-4-6 error code actually means
Your Bosch refrigerator has detected a problem with the motor that crushes ice into smaller pieces when you select the crushed ice setting. This means crushed ice dispensing may not work, though other refrigerator functions should be unaffected. A technician will need to test the motor and possibly replace either the motor or the ice maker unit.
