When I turn the valve and get the pressure dial up to bar 1, it switches itself back on and is fine. It keeps doing this every couple to three days. Why is my boiler losing pressure???

Check for leaks on your radiators/system. If there are no leaks, it will more than likely be that the expansion vessel on your boiler will have lost its charge. This will need repressurising. Unfortunately, this should only be tackled by a qualified engineer.
Good luck!

You most probably have a faulty Pressure Relief Valve, and causes the boiler to lose pressure. It is a job for an engineer unfortunately.

Combi boilers work on a closed pipe system all the water in the system is pumped in a circit from the boiler thru all radiators and back, pressure is lost when some of the water is leeked on the way around. Check for leeks in your system.

your boiler is most likely to be losing pressure because of a fault with the central heating pressure vessel which is either blocked with sludge or leaking,when this component fails pressure will build up in the central heating system when it warms up,this excess water pressure will be released by the pressure releif valve ,because of this you will eventually end up with low pressure.A competent diy,er could easily replace the pressure vessel but if you supply the component it probably won,t cost much to have it professionally fitted.

This happened to me and it was because I had a leak in the system.
I'm no expert though - you'd best get a good plumber in (preferably one recommended by someone you know).
There are a few guys on YA who are really good on this sort of thing, so maybe you'll get an answer from one of them.
Good luck.

Water leaking from somewhere. Check all the visible pipe connections for leaks, flush system and use leakstop.

there was something on watchdog a few days ago about boilers, maybe you should check it out see if its the same problem as other people were having, get it fixed for free?!
