i have a vaillant ecotec pro boiler. the hot water stopped working the other day so i checked the boiler to find the pressure had dropped to almost zero. so i topped it back up again but it wont switch on and has no power to it. i've checked the fuse in the pcb and changed the 3amp fuse but no joy, any ideas anyone?
thanks paul. i've found very small leak on one of my radiators. probably about a thimble full over a day. i've managed to fix this but i dont have a manual. do you know how to reset the boiler?

1st of all you have a leak somewhere causing pressure loss when you have found this check the manual for the reset procedure after pressure loss
