Vailant ecotec pro 28 pressure

[Johns23]

Hello.

I’ve lived in the property for 4 years and anytime the pressure got low (0.8 bar) I would use the fill taps to release more water into the system. Ever since British Gas did their annual boiler check about 3 months ago, I’ve had to do this too up method more and more. My pressure is now 1.8 bar which is too high but seems to lose pressure and need topping up every other day. I can’t see any leaks and the pressure reading isn’t changing so any ideas why I’m losing my hot water and heating until I let some more water into the system and then it fires straight back up?

If you have British Gas cover you may need to use it and call them out

Thanks for the reply. We don’t have that but considering using their repair and cover service.

Check all radiators and visible pipes including the small copper pipe that goes to outside form your boiler

For leaks? I can’t see anything wrong with any of them.

run your heating for an hour then check what the pressure gone to.

It actually went up to 2.0 now it has the f.75 code again and all off. I’m not going to fill the loop again and call out BG I think.

Tbh better off calling a local gas safe engy out repair I think would be around £40 plus vat etc

its the pump or your flow senser thats playing up. with the sound of things.

Thank you. British Gas are coming to look at it tomorrow so hopefully will be easy to sort.

BG - Don’t count on it. I hope you get it sorted, but would have gone local independent familiar with this boiler.

So BG came round today and said 2.9 bar is ok!??!! I called back afterwards as that’s not what it says anywhere else and they are sending someone else tomorrow.

I drained the radiators and the reading was stuck at 1.7 bar so turned on the boiler without refilling as didn’t want to add more pressure. It made a lot of strange noises and smelled a bit funny but not of gas. I then checked the dial and it had zero pressure at all. I quickly filled it with some water from the full loop and it’s working again but worried I’ve done damage.

standard bg least they turned up I wouldn’t go off the digi guage go off a mechanical one

As the digi pressure sensor is fecked / blocked

 

[Johns23]

Thanks, definitely a lesson learnt. Is it possible I’ve done damage starting it up with low pressure/hardly any water as believed it was at 1.7 bar? It made a real racket as though trying to flush water through and had a funny smell, not burning or gas though. I then filled with water but still not enough so made the same noise then I ended up filling up and seems ok now but worried it could have caused damage?

I’ve just turned it off now until BG come tomorrow.

Short term you are fine long term eg overheating sounds like an aircraft going over thumping and banging etc it would cause damage
