Hi guys,
I’m new to the forum and hope to have your advice on my Sab Nobel problem that probably due to overheating.
So brief info on the machine that I’m second owner and it’s about 2 years old. The machine has been in moderate use on 5-7 coffees a week and backflushed with chemical once a week.
The problem started when it automatically turned off then I have to let it cool down before I could turn it on again. As the shut down repeated, I brought it to EspressoWorks(Perth) to take a service before I bring it to Brisbane due to moving interstate. Machine underwent service with several replacements like group seal, anti-suction valve, inline water filter, obviously nothing related to heating components. Therefore, after I got it to Brisbane the problem reoccurred then one day it totally shut down, nothing seems working except the water source indicator lighting up.
I know I could bring it to repair shop again, but I would also want to learn a bit about machine. So I have multimeter maybe you guys could give me bits of advice/instruction on what components I could test to diagnose the machine problem to figure out the possibly broken parts.
Thank you in advance.
