Hi can anybody help me, i have a baxi 105e combi boiler everything was working fine till yesterday suddenly the pressure dropped, so i pressurized it back up to about 2 bar, now i cant seem to get heating on and whenever i turn the hot tap the pressure drops straight away. I've tried resetting it etc, and all lights seem to come on along with the gas firing up for about 10 seconds, it's driving me mad!!
