My boiler pressure has dropped off on a baxi platinum 33 and when i turned on both valves to open the filler loop the pressure didnt seem to increase,it must have a little as the boiler started up as it was already calling for radiators but once the gauge got to 1.1 it didnt matter how long i leave the filler loop open no more pressure would go in. it's done this before in the past and when i disconnected each end of the filler loop there was lots of water coming out so it wasnt blocked.
Also there is nothing coming from the pressure relief vavle so its not just a stuck gauge
