Hi, I have one of the above said boilers and its flashing F which is meant low system pressure but i dont know how to fill with pressure?? can anyone help please as i need a bath and no hot water lol xxxxxx

Look for a flexible connection and you will find one maybe two black levers. Turn it or both 1/4 turn until pressure is at 1-1.5 bar.

its not flexible its a solid 10mm pipe that joins the return and cold pipe together (the 2 pipes furthest right) when looking under the boiler. It sometimes has black levers but at times has black knobs.

ferrolli tech help line last week for an optimax with faulty control panel "hit it 12 times, quite hard" (loosens jammed relay on circuit board), a common problem it would seem, works but doesnt fill one with a sense of how reliable this manufacturers kit is!!!!!!!!!!!!!!!!!!!!!!!

Reinforces my opinion that Ferolli's are a pile of poo.........

Mind you..... "hit it 12 times, quite hard"...... That's genius that is!
