Vaillant boiler issues F28 on ecotec 430 not the normal culprit

[Harvest Fields]

I would say your boilers are oversized and your gas is undersized.

So they need a Gas safe engineer to go back do they not?

Also I hope op is not testing the mbar

As @Craig Watson says. If they are under two years of age then they are definitely within warranty. I would suggest you get the installer to come back and deal with this or book a visit from Vaillant.
If you choose the latter, there is a charge if the fault is not Vaillant product related.

This is of course assuming they have been fitted by a registered engineer and have had the warranty set up.

Definitely and thats the last advice I'm giving op on the subject

Not withstanding the F28, it would appear you have a you have 2 oversized boilers on a poorly designed system, I take it from the single large pump that there is no low loss header installed? (60kW through 28mm what were they thinking !!!)

Why haven't you gone back to the installer / manufacturer before now?

When you go down to reset, is it both that show the F28 ??

Why if it still does it with just the one switched on ?

Where does he say this still happens when only one is switched on?
