Something to note here is that my filling loop has always been rubbish and leaks water when you use it (have to put a bowl under it) - but usually it has always done it's job and filled the boiler when it has been needed every now and again. With the heating, the pressure will sometimes go up to 2 bar (from 1) and it heats up nicely, then the pressure will drop until the boiler stops working and the red light comes on. A quick top up via the (leaking) filling loop and it would work again. However, when I went to put the heating on, the boiler would lose pressure after about 30-60 mins and it would cut out and the red light would flash. I picked one up and he fitted it and the boiler came back to life again and seemed great, no more gremlins! He finished servicing the boiler (had to re-pressurise the expansion vessel during the service) and I thought everything was great. It was due for it's yearly boiler service anyway, so my boiler engineer came over and said it was down to a faulty circuit board. It was acting very strange when using hot water, struggling to get going, it would work for a bit and then and both bars on the display would flick all the way to the top and then it would cut out and the red light would flash on it. I was away for 5/6 days and when I got back, the boiler wasn't right (it worked perfectly before this, but the central heating hadn't been switched on for months). This boiler was already installed when I bought my house and it has served me well in the 7 years I have been here (it was installed 14 years ago) - I have had it serviced every year as I believe if you look after things, they will look after you. Quite a lot has happened to get to this point, so please bear with me. I am really hoping someone can help me here.
