leak inside boiler?

[competentnovice]

Good morning all.

Last night I heard a drip coming from the boiler (SIME ecomfort 30HE). There were no visible leaks externally.
About 4 months ago, I repaired an aquafilter leak with new gaskets, and assumed it was something to do with this, so took the cover off to inspect.
Nothing that i can see. No sign of water where it shouldnt be!
I can still hear this drip though. its DEFINITELEY coming from inside. I can only imagine its in the part of the boiler where the heat exchanger and gas burner live. My question is am I allowed to remove the cover to this part of the boiler to inspect for a leak, or does this have to be inspected by a gas safe engineer?
Better to be safe than sorry!
Thanks
Matt

Sorry forgot to add that the system appears to be holding its pressure, and still operates correctly.

Could be a leak on the hot water side. Time to get a gassafe reg plumber or heating engineer in.

If the cover is not part of the combustion chamber, you can remove it. The M.I. will show you.
