Vokera compact 35 he problems.

[Russell]

Can anyone help me with this. Was getting no heating and hot water. Spoke to Vokera and explained symptoms and they said clean Venturi which I did . The beige part at Venturi was broken which don't know if this is cause because boiler fired after a cleaned Venturi for about half an hour then went to pick daughter up from school and boiler off again. Won't come on at all and is now flashing green in the off position on the control knob in front which it never done before. Has a look at Venturi kit to buy and it looks a bit different and more parts than needed to replace existing. Any help guys?

Check fan blades, might be full of dust. Check differential pressure on fan about 2.5 mb. Flue blockages, correct restrictor on flue, air pressure switch in no and nc positions.
