My Baxi boiler needs a top up, something i can do?

[markbigears]

Afternoon all, I've recently moved and have a Baxi solo 3 PFL 80 fiited.
Since putting the heating on, i've noticed the boiler fires up for 20 secs, stops for 20 secs, then fires, stops, and so on. I looked at the pressure gauge and its .5 as apposed to 1.5-2. Had a look on tinternet and looks like the boiler / system needs topping up from the mains. Is this something I can do or do I need an expert to look at it? Is it safe to use the boiler in the mean time? Any advice welcome. Many thanks, Mark

Should have a filling point somewhere. This may help..........

Cheers Dickymint, i have looked at this before, but couldn't see anything?

This is a common issue with sealed systems (combi boilers mostly). There will be a tap near the boiler somewhere, sometimes just one that is operated by a screw driver. Turn this on and you will hear the water going in. Look at the pressure gauge until it os over 1bar say 1.5bar, then turn it off. If it drops again though you may have a leak and will need to look into this.

Hi Peter, so i'm looking for a tap near the boiler not actually on the boiler? As there are 4 pipes going into the bottom of it. Great taste in cars you have

Don't think the came with integral filling links, there may be one externally.

Should look like this.....



Open one tap fully, then slowly open the other until you've reached 1.5 bar than close them both.

Not all of them have two taps so may juts require opening the one slowly.

Thanks very much. Yes the tap is not on the boiler but usually near it underneath.

I was writing a reply at lunch about how to re-pressurise, but it didn't sound like it was the answer so I cleared it. Many boilers either work at .5 bar or don't, start stop didn't sound right.

Many thanks for all your help, really appreciate it. Will look for the pipe when I get home, really hoping it's not the PCB, replaced one in my Baxi in my previous house just before we moved!

That's not a water pressure problem, I'm fairly sure the Solo System boiler doesn't sense pressure. You'd have to have no pressure and air-locking for the thermostat to do that. As above, I reckon it's the famous Solo PCB.
