Location Help

Where to find this

Use this as orientation before touching the machine. It is location help, not a repair instruction.

Power entry and lower service area

Start outside the machine at the outlet and cord, then identify the power entry area before any protected-compartment inspection.

  • Wall outlet, power cord, power entry, and terminal area
  • Controller enclosure, wiring harnesses, and door-hinge cable path

Do not open energized or protected electrical areas unless a qualified technician or licensed electrician is handling the work.
