Funny story. An owner of a nearby bistro brought his La Pavoni commercial 1 group 'Pub' model espresso machine in for a service - which turned out to be a fried Pressure stat. I noticed the machine did not have an internally installed motor & pump & assumed he had it mounted under his counter at his shop... On completion of the repair I mentioned the missing motor... nope... he had no idea that he had been running his espresso service on line pressure for months!
This week had an on-site repair of an Astra Mega 2 with yet another burnt out Presure Stat
At the shop we had an overheating La Spaziale Vivaldi. It needed a new thermostat probe & a good cleaning and tune up. The 2 boilers in the Vivaldi do not use pressure stats to control temp - they each have probes with leads to the cpu.
