How do I top up the pressure on my Sime 100e bolier?

I have one of these boilers. There should be a little valve near the boiler. Mine is blue. Its on a bit of flexible hose. You turn it to the right to let water in then back to 12 o clock to stop the water once the gauge on your boiler is back into the blue (safe). Hope this helps.

Your boiler has something called a 'filling loop' which effectively allows mains pressure water to be bled into your boiler. You'll have to find this filling loop, and turn it on slowly until you get the correct pressure. Don't overdo it though as you'll have to get the water out again if you do.
