What method have you employed with reguards filling the system.
Has the braided hose that comes off the expansion vessel been plugged in.????
I'll bet it's not.
I'll bet it's not.
Methinks you would have a fair bit of water pi33ing out if that was the case.
Obviously you have never fitted 1 of these you S M A R T A R S E !!!!
The jig has the expansion vessel attached to it.
Once you mount the boiler you then remove a blanking plug from the boiler and then put the braided hose in and then clip it.
If you dont do this you get the exact symptoms the o.p describes.
You are almost right, bar 1.
After that experience I decided to stick with CDI, or HE plus as the predecessor was called. Couldn't say jay or nay to the existence of a plug 5 years later. Fairly sure that if there was a plug on those models, it wasn't one that would withstand 3 bar at 80 degrees though.

would think either filling loop letting by or have known this on a potterton with a pin hole in the heat exchanger, condensate was running a lot on that though
many thanks, no i am an installer, this job was done spot on x100 the lot, what i was after finding out is if any other 28i juniors had this problem. the filling loop is disconnected. these have 2 year guarantee, and i think they are trying to pull a fast one at my expense. pin hole in plate to plate from new i suspect.
so you popped in a bottle of x100 inhibitor,
but did you clean system and be able to prove that after you fitted the new boiler the system water was ok.
cos if manufacturer has been out under warranty for a goosed plate hex
they just about always take a water sample,
if sample shows contaminated water they won`t do warranty repair

O.P states that it has been happening ever since it was installed.???
