stuck pressure guage on ferroli f30

[coocumber]

i have a ferroli f30 with a stuck pressure gauge.
no matter what happens the gauge only shows about half a bar.
this is still the case even the system is drained out. the prv was dripping the other day as it's a little difficult to fill it right pressure without that gauge.

am i right in thinking a new pressure gauge is the solution? or is there separate sender unit (if it's not all in one)?

is it hard to change?

many thanks in advance.

f30 has a two year warranty get the installer who filled out the benchmark book to contact ferrolli who will be more than happy to replace the component

Chances are that it's actually the entry to the capillary tube leading to the pressure gauge that's the problem - probably it will be blocked with the crud that the installer failed to flush out of the system when the boiler was installed.
