Vailant Ecomax 828 problem

[matpol]

Hi

We have recently had the above boiler installed - it works fine apart it's annoying problem of loosing pressure from the CH. It throws a fault code which is F.25 - i have checked the manual and this fault is not listed - anyone know what this means?

It's easy enough to refill the system but slightly annoying when you want a shower first thing in the morning.

I have told the plumber who installed about the problem and he should be paying us a visit soon but I thought it would be good to find out what this fault might be before hand.

Cheers

Somethings leaking.

methinks you may have a point

thats kind of what I think but I would expect to see wet patches around the place which I am not at the moment.

Is there some way I can try and trace the leak if there is one?
