Pressure and temperature go too high
My machine pressure overshoots to 2.5 bar or more. I took off the lid and unplugged and re-plugged all the push on connectors (cleaning contacts) this may have fixed the problem or it may have been a coincidence that the problem went away, but now it is back.
Anybody else have this problem and found a solution?

Pressostate need replacing. membrane is always OK but Cherry (red) microswithc has given up (60C spec do last for a year +, but no longer) /// Olev
I replaced the pressurestat with a Sirai one which is supposed to be much more reliable than the original. That did it.
