Hello people! just as the title says our exobar coffeemachine is tripping our eletrical circuit
So what happened first? The coffee machine was just working fine since four weeks ago. After it kept tripping our electrical circuits. At the time I didn’t had the time to troubleshoot the issue.
The machine itself has some been repaired once or twice. I think it was the same issue as right now. Last time they replaced the motherboard to solve this current issue. But to me the motherboard looks just fine.
The condition of the machine: it is operating in a clean working environment, the machine is 8 year old, and it only received light maintenance.
So last week I did some research about our machine, so I turned it on and it just worked fine (somehow). My aunt told me that the coffee machine was shutting itself down while it was building the pressure and heat. What I did was lower the amounts of bar to 1 (with the pressurestat) and replaced the pressure valve (because it made an irregular sound, the ‘sst ssstt’ sound). After that I seems to be working. After that I dropped my screwdriver into the machine ( didn’t hit anything) and I turned off the machine, to safely get my screwdriver out. When I turned our machine on again, it was tripping our electricity circuit again….
The troubleshooting I worked on:
I tried a different a different wall socket but no luck
checked the conductivity of the heater elements, they all looked fine (all around 31 ohm orsomething).
i also turned the machine on while the heating elements were plugged off, and the result was that the circuit got tripped
unplugged the motherboard still a circuit trip
I checked for unplugged cables, but everything looked fine.
i measured the connectivity through some cables, seems fine
I did not checked any relais
wet spots, no electrical components were wet at the time.
hmm maybe I just need to buy a new circuit motherboard… idunno haha

if you guys know something i would like to hear it!
P.S. sorry for my bad english
