Why does the system power input fuse (20A, 25A or 30A) keep blowing?

  • Chances are it is a bad pump or blower.
  • Make sure to replace any blown fuse with a fuse of the exact same type and rating.
  • Unplug all the pumps and blower.
  • If the fuse blows again, verify proper internal system wiring and check wires and connectors for cuts and burns.
  • Replace the device that blows the fuse.
