ariston microsystem 15 low pressure problem

Hi, I am having problems with my boiler. The pressure in it is only 0.5 bar. Just wondering if anyone has any ideas on how to increase the pressure. its sopposed to be over 1bar. I can't find the fill valve, any ideas what it would look like or where it might be.
Many thanks to anyone who can offer a little insight .

Is the boiler on a semi-sealed system? If so 0.5bar would be normal. The fill valve is mostly in the hotpress. It could be a silver braided hose with two valves on it one either end. Or a half inch pipe dropping out of the ceiling into the return connection on the coil of the cylinder.

Was the pressure higher on it before or was it always 0.5bar?

hi johnniek,
Thanks for the post, i have checked with one of my neighbours her pressure reading is the same. I had no luck finding the fill valve. Thanks for your help.
