valliant boiler problem

[draz]

Running out of gas doesn't cause your pressure gauge to go to zero period.

It may be that he only time you look at your pressure gauge is when you run out of gas. But it's not the cause. If what Steelmasons says is correct then you would get F28 before you run out of gas and every time the pressure drops. I doubt this is the case.

thats is exactly what seems to be happening

No, the pressure was above zero, it was 1.25...a little low maybe, but not at zero..

But in your opening post you stated:

I finally got my gas on, went to start the boiler, and got the f.28 error, over and over n over.. The pressure I noticed was down to 0.

Forgive me for being confused.
