Boiler loosing pressure

[Eastlincs89]

The pressure in my boiler seems to keep dropping. I can't see a leak anywhere and the boiler keeps make like a boiling bubbling sound? Any ideas?

Yes, you need a gsr in to check it over.

Thanks, the Worcester engineer is booked for the 14th as it's only a month old so under warranty obviously. Just wanted to ask in the mean time

ive finally managed to bleed all the rads in my house, a stupid amount of air came out of all of them. Could this of been reducing the pressure in the boiler some how?
