Ian. Also when using the old board we had hot water but no heating. We were getting fault A02, after several attempts to fix I decided to get a new pcb. But now no hot water. So flow rate must be ok as it we had hot water using old pcb.

Hi Ian Not sure what you mean?

Hi. Just fitted new pcb and heating works great however hot water is luke warm. Starts off very hot then runs cool at. Temp does not get any higher than 34 degrees. I have set the dhw temp to 50 degrees but still not get any higher than 34. Is there a engineer setting that I need to...

Well I brought a new pcb. Put it in set the boiler to come in on timed and it seemed to be working perfectly. That was until I put the boiler cover back on. Then within 5 minutes it had tripped out to A02 again. Took boiler cover off reset boiler and worked fine again. So put cover back on...

What shall I adjust them to. Instructions say min 0 max 100. Would 80 be ok? Or is that still to high? Thanks again

I press the override button on the clock. You can have it on timed, permanently on & there a override function. If you put it on timed it cuts out after 5 minutes. If you press the menu button so it's 'on' permanently again it cuts out after 5minutes but if I select override it stays on much...

Have just found if I put the boiler on override it works and has not tripped out in the last 3 hours. Where as on timed or permanently on it trips out every 5 minutes

Thanks ianmcd. I am fully aware of how crap this boiler is. I priced up a pcb for this boiler and it £180 +vat. So don't really want to spend that amount if it still don't resolve the problem. Might be worth saving up for a new boiler than waste £180 on this crap boiler. Thanks for...

Having some problems with my Ferroli domicondens he26c Theboiler keeps tripping out and fault A 02 flashes up with and boiler will not fire up for hot water or heating. Have to reset the boiler and it works for about 5 minutes. I have watched what happens, boiler fires up. Works for about...

Thanks Baldev I have put the program on to Eco and it been working ok since then but every now and then it trips out with fault A02 so have to reset it and it works again. So by changing ignition cable stopped your A02 fault? I already changed the clock so know that working. Thanks again

Could it be the boiler overheating? I turned the heating up yday. To 59 degrees and last night once I got it reset it cut off on code A 02. Since probs this morning I turned boiler back down to 48 degrees and boiler been on for about half an hour and working fine. So is there a sensor or...

My optimism about being fixed may have been short lived. The heating went off in the night and fault A 02 back. Pressed reset boile reset and fired up again for about 15 minutes and tripped again showing A 02 so pressed reset and code D04 this time. So I got over the boiler not firing up...

Thanks Leezer. Finally got it working again. Thanks got your link to the instructions. I looked at the clock wiring diagram and noticed that the room thermostat wiring block needed to be a closed circuit. Well when I took the old clock off today I noticed that there were 2 wires connected...

Thanks Leezer. Those links are very useful. I called the local boilere spare store today. They advised me that it was a simple unplug and reconnect process. They never mentioned anything about amending settings!! I had a look at the pcb. And I no electrician or heating engineer but there...

Problem is now there no fault codes, hot water works fine but boiler will not come on for the heating at all. It not even trying to start up.

Hi Tony. Agree with what you say, so Seems like the pcb now, prob a relay stuck or something. Now do I spend £200++ on a new pcb or buy a new boiler!!

I spoke to a plumber today and he said it more than likely the clock as we still have hot water and the problem with the timer. New clock purchased but now still have hot water but can't even get rads on even using override. No faults showing and no external thermostat Bled all rads...

Hi Tony I did have emergency insurance, which covered a boiler breakdown. So called the. And they sent out bg engineer. He came straight and straight away said it was pcb. He come to the conclusion as when he took all connections off it and put them back on again a different fault code...

I had a British gas engineer come and look at it, he said we need a new pcb. He removed the sensor wires and the connector from the pcb and when he put it back together another fault showed and nothing worked. He said it defiantly pcb. I took it apart after he left and reconnected it all and it...

Hi Tony Unsure we been moved in 12 months ago and it a relatively new boiler. But not under warranty as it was not registered with ferroli when it was installed and no instruction manual When we moved in. Just don't want to spend £200 on new pcb if it just a timer fault. Thanks
