Hi again,
OK, so I can use a scope to check the power coming in. I have an old PHILIPS Pm 3231 scope with leads. Will this work?

And again, even if I find a problem how do I reasonably protect the circuit?
I cannot sell my customer on a surge protector if it has to be reset constantly; this is a high volume cafe.
I cannot even find anything on a "slow turn on" on a google search that isn't related to relatively low-amp stereophonic and electronic equipment. This is a 2 group espresso machine with a 3500W element.
My client isnt going to invest in a Liebert/Emmerson UPS with batteries and inverters just to keep the espresso machine I sold them from frying the card? In any reasonable client's POV it is my problem. Especially when pretty much every other installation I've seen has been running volumetric machines for years with absolutely no special protection of any kind.
Unfortunately the live music events taking place several times a week at this place make up a significant portion of the cafe's revenue, and a lot of the bands playing there bring their own equipment, so rather than chasing sources of noise or asking them to give up hosting out of town bands, I need to find a cost effective way to protect the circuit. The 2-group Simonelli that this machine replaced worked there for years and the autofill box never fried. Their perception going into this purchase as well, was that volumetric machines were to be avoided because the brain boxes tend to fry and hamstring the machine. 3 months in, and that's exactly what has happened.
