Gotta love trying to diagnose problems by e-mail.
Fortunately a video came through earlier.

Fault reported - Both machines are faulty and no longer work.
After suggesting plugging a vacuum into the wall outlet and working back
from there I was informed that all points had been tested with a circuit
tester and the machines must be faulty.

Had a video through earlier showing testing.
Anyone else spot what I consider to be the cause of the problem(s)?
