I have a Vivi that I have had for a couple of years, bought used.
It has a couple of times now just sat there hissing steam, which I presume is the OPV. The pressure gauge was reading at the top of the gauge.
I am presuming pressure stat?
After a power down and open of valves to let off the pressure, it seems OK,
Am I righ in the idea that it's the pressure stat? If so where is the best/quickest place to get one? What is involved in replacing it?
Thanks,
Paul.
