Leaking Saunier Duval Thelia - but what's leaking??

[FrankieP]

My Saunier Duval Thelia has been leaking small amounts of water from underneath the boiler for a while now. I have had an engineer round 4 times and he has serviced it, replaced the pressure gauge (as this was faulty) and most recently he replaced the water pump in attempt to stop the leak. It's still leaking. The mystery is that neither he nor I can actually see where the water is coming from - it drips out the bottom of the boiler coming from a black metal rectangle bracket (sorry, don't know what the part is). It seems to pool there before dripping out.
It doesn't leak all day - only in the morning when the heat comes on. At midday and in the evening when the heat comes on, the metal bracket is bone dry. There is also no loss of pressure.
Any ideas? - I don't want to keep replacing parts randomly as it's getting expensive!

these are the only boiler we do not work on! Thats because they are so prone to leaks!

Better to replace the boiler!

Special feature sir. When they've stopped dripping, you know they must be empty.

Replace the reversing valve and hoses.

As no water pressure drop would suggest condense leaking back into chb from flue.

Do yourself a favour and scrap it, then invest in a quality boiler that will last.

Hi all

A friend has the same issue here, the boiler wasn't actually leaking until i noticed the pressure was low, so they put it back to 1 bar and now it drips every so often.

It seems as though it's every time the toilet is flushed....

I messed about with it and managed to get it to stop dripping by leaving the water intake valve open slightly, BUT then the pressure started creeping up...!!!!

Any ideas?
