If your BUSCH Water Pump starts but runs noisily or rattles, check for loose connections in the drive motor terminal box, ensuring all motor coils are properly connected according to the connection diagram, especially on motors with six coils. Tighten or replace any loose connections. Also, verify the pump is running in the correct direction. If these steps don't resolve the issue, the pump may need repair.
