Occaisionally the pressure will build beyond beyond one bar. It is intermittent, and when it happens the machine will make hissing noises and then the pressure can build beyond 2. Today it went above 2 and created a lot of steam all on its own before I realized it and shut it off.After it is shut off and then I turn it on again, it generally only goes to 1 bar again and is fine for a couple of days.
