Hi all, everybody knows what the Lever does when the Portalfilter is not correctly locked in the brew group 😉.
In principle the same can happen when the valve, which is used for feature automatic release, is erroneous. When you feel safe, because you have locked the portalfilter correctly, standing close to the lever during preinfusion, what did ACS foresee to mitigate the safety risk that a broken valve releases the pressure accidently.
I heard from this safety feature, but this seems to be optional.
Best Regards
