I have a continued problem with my boiler that just won't go away! About once a week the heating & hot water go off & code 'A02' appears on the boiler display. After pressing the reset button it fires up and all is well until it happens again. I've had a Ferroli engineer to have a look at it twice now, first time he placed it in test mode which took the temperature right up to clear any oil, debris etc. The problem continued & 2nd visit he replaced the circuit board. The problem hasn't disappeared. Before I call them for another visit (& possible charge) I'd be grateful of any suggestions that I can put to the engineer that might help resolve this issue. many thanks

Hot water is fine ... but continually the rads do not work. Timer is on, thermostat turned up boiler burns and heats water (I think) but does not appear to pump around system. Have checked a few rads they are bled ... any ideas, seem to be using gas but not getting heat - help before the winter would be appreciated!

David thanks for your advice. I will try the leak sealant and let you know how I get on. Thanks again.

From what you write, I understand that you have to fill the boiler up with water once a week, (why) if you have a small leak some where, and the presser gos down the low water switch will cut the boiler off, You re fill the boiler and re set (yes??) If this is what is happening you need to find the leaking water (where!)The cheapest way is to put in leak sealant in a rad, Please let me know how you get on David
