Hi all,
I have a 1999 pub E single group which has just started going over-pressure (about 2bar) and was hissing constantly while switched on after warming up. Im assuming the hissing is the pressure relief valve, which Im used to hearing, but not constantly.
Where do I start looking for the cause? I had thought maybe the element wasnt switching off, so a thermostat might be the problem.
Any ideas??? [smiley=undecided.gif]
thanks,
Mark
