Hi all,
My 10 year old Puma brought up the low system pressure light the other day, shutting it all down. The gauge on the manifold showed 1.5bar. I drained the boiler down and the gauge followed the pressure down. Thinking it was the pressure switch, I replaced it and all was fine for a few days. The light then came on again and stayed on. Tested the switch and it is OK. Taken the system pressure up to 2.5bar and back down again and the light won't clear.
If I link out the switch all works well.
Appreciate any suggestions
thanks
