I have the ACS Vesuvius Espresso Machine, I have owned for around 7 months now.
Today I was unable to brew my normal espresso shot and found the screen displaying this error message.

"Coffee Temperature 1, and big triangle on the screen.
I went to the manual and they said that in this case we need to reset the red temperature stat button on the top of the brewer, I opened the to panel and found a button on the brewing boiler "Black though", I pressed it and it did not seem to press anyway.

I have made a video to show what's going on on the screen. Link is below

I'd appreciate any feedback on this. Thanks
After Pressing the restat button which I was not sure it it is pressed or not as it was "rigid" and did not give a feeling of press.

Hi Mustafa, welcome to HB.
In the second video i can see a crazy fluctuation in the displayed temp, so probably the problem is the coffee boiler temp probe, you better contact your vendor before do something wrong.

Thank you for your reply.

Yes I contacted the manufacturer and they confirmed that the brewing boiler probe needs replacement and they are sending me one.

I temporarily switched it with the steam boiler one and turned the steam off.
