Has your filling loop been removed? They are really supposed to be removed
once you've topped up the system. There will still be a connection point on
the coldwater pipe and the CH return ( or flow? ). Some combis have built in
filling loops: my Vaillant has two valves built into the underside of the
casing, it takes two special little keys to open or shut the valves. It's
all very inconspicuous.

You must have a Eco/Turbomax/Thermocompact Plus model. About 5 years old
or less.
The OP has something from about 10-20 years ago.
