I noticed my cistern is passing a bit af water into the bowl all the time.
I took the flush mechanism out to check it over and it all seems in good
order except that the sealing washer/diaphram has a small moulded bump on
it. I wondered if this is normal. Has anyone dealt with one and can
confirm?
If the clean I gave it does not give a fix then I guess I may be looking at
the seal between the mechanism and the cistern.

Sure it's not overflowing? Most modern cisterns overflow via the flush pipe.

Check the ballcock...

No - definately not reaching the top of the tube. Level gets lower over
time.

I have on that always does that unless you give it a full flush. I know I should replace the mechanism but haven't summoned up the energy.

See the little bump - it seems counter intuitive to me:

Our 5 year old bog did the same. Out comes British Gas, wife loves insurance
:-( and replaced the innards.
Now its doing it again and I can't be arsed picking up the phone.
I don't think that bump should be there.

I wonder if it's doing what ours is, something in the operating part of
the mechanism is "sticking"* and is lifting the sealing washer by a
fraction of a mm. Enough to let it trickle. Joggling the flush button
seats it until next time....I know, it's on the list

*Think it's where the white plastic arms lift the red plastic "float",
but there are no obvious signs of wear and silicon grease didn't help

I have contacted Wirquin. Mine sticks in the flush pisition very
ocassionally joggling the button fixes it - I suspect something doesn't
return fully.

Assuming you have a conventional syphon, they fail "safe" and won't pass
water.

So it's either overflowing (check float valve).

Or there is a leak at the point where the flush syphon passes through the
base of the tank.
Take tank off and remake/tighten this joint.
