Hi All, Im having issues with my boiler heatslave 18/25 over the last few days the CH will not work (boiler not firing up) when i press button for it to switch on i can here what sounds like a solenoid or something click from inside the boiler but nothing else happerns, the hot water seems to work as normal, i have managed to get the boiler to fire up by pressing the reset button but cant get it to fire up very easily or very often. There is the usual power light on the boiler and lock out isnt lit up, when i did manage to get the boiler to fire up i pressed the large lockout reset button behind the front panel and also the two little reset buttons but nothing happerend straight away i just faffed and eventually it fired up but now ive tried that again and cant get it to work? also the two little reset buttons don't feel like a physical switch? what do they press onto? also i tried bleeding rads but no air present, pressure is at 1.5bar. any help would be really appriciated and as you can probably tell i dont know much about boilers im a car mechanic by trade so should be ok with them?? Thanks guys..
