/diy/ - Do It Yourself

I am working on a coffee machine that is having trouble producing milk foam. Looking at the hydraulic schematic, I have determined that the culprit responsible for the problem is most likely a solenoid valve. What would be the best way to test this valve outside of the machine be? I'm thinking that since it's 120V 60HZ, the best way would be to use a cheater cord to hook it up to my isolation transformer, but I decided that it would be best to ask before I do it just in case I do something retarded. If this valve is bad, is this valve here a suitable replacement (https://www.ebay.com/itm/solenoid-valve-coil-120V-60-for-Jura-F9-Jura-F90-coffee-machine/383457242639?hash=item5947d52e0f:g:nhcAAMXQVT9SrdlM)?
