Water in boiler cupboard?

hotcookie101

I have a Halsted quattro gold combi boiler that is in a cupboard
in the bottom of the cupboard I keep pans/roasting trays etc. The pipes for boiler (where can top up pressure etc) are not boxed in.
taking a roasting tray out today I noticed that the pans at the back seem to have a small amount of water in them. I cannot see an actual leak from the pipes. Could it just be condensation?

Pssst

Unlikely though it depends on volume ! Saying that,if it was condensation then it would be apparent in other pans and in the cupboard generally.
It is likely to be either

Leakage from primary or secondary circuit
Rainwater getting in via boiler flue or other opening
pressure relief valve leakage

I'd tend to think it was the first of the three

Monitor the boiler system pressure guage and check if it has dropped or does drop over the next few weeks. Do take care to note the pressure when system is cold to ensure accuracy. How often if at all,do you have to top uo the pressure?

I topped it up yesterday from 1 to 1.5 (when cold, we don't have heating on at moment, only hot water, haven't topped up since march time) but then today it has shot up to 3 and is leaking from the overflow outside
Very confused-how can it go up without me adding anything?

pressure in the system will rise with heat, 3 bar sounds excessive, therefore probably some fault is causing temp to rise too far...
..or....
tap/s on filling loop not fully closed/faulty and allowing in water, you should be able to completely uncouple the filling connection if not allready done so.

hope this helps.
