This is a few things that I would look at immediately - BEFORE TURNING ON CIRCUIT BREAKER!!!
power can shock, cause serious injury, damage property, and may result in death!
-find out how many appliances on same circuit, try a known good outlet with no load(s) if possible.
-check machine cord for damage, plug end, cord length, entry to machine.
-check underside of playfield for shorted power cord, transforms etc.
-use caution and care. GL
