Ok thanks. So what would you suggest doing. Because it will work and run say for an hour and then it won’t fire up usually until the following day. But as I say it will run fine in service mode.

I don’t mean 5 bar pressure. Just 5 bars on the screen meaning it’s burning the full amount of gas. I think it’s called being in service mode.

But if it was the hoses why would it run fine as soon as I put it in service mode. Service mode runs it on 5 bar gas and it runs fine. I'm puzzled

I have a viessman vitodens 100 and the heating will work and all of a sudden it will turn off. It is not a set time when it turns off. But it seems when the gas burner is not needed it will not re-ignite. Its usually when it hits 69c. Once it cuts out the heating will not come back on. either...
