hi i am dan, i can help you with this. what is the full model number of the boiler?

HiOptimal he plus 31 c
Expert:  Daniel Plourde replied 1 year ago.

this is where the flue sensor is, are you getting an f7 and f14 error code?

Customer: replied 1 year ago.
Hi it's giving fault codes f7 and a4 would you think this would be to do with the flue sensor?
Expert:  Daniel Plourde replied 1 year ago.

i would not think a bad sensor at first, there is a separate fault code for a faulty sensor. that error code is due to too high of a flue temp. what temperature is the boiler set to, what is the return water temperature?

Hi Dan,
It's set to 55 but on screen it says fh at the moment ?

The water does get really hot tho then it will bring up code once been running for a while. If I was to run a bath I would need to reset this 2-3 times

ok about how long is the vent pipe? i would also recomend turning it down to 48 and see if that helps it

Customer: replied 1 year ago.
Sorry what is the vent pipe I know a little about plumbing no expert ?
Expert:  Daniel Plourde replied 1 year ago.

the exhaust pipe where the flue gases come out. how long is it from the boiler to outside termination did you check to make sure there are no obstructions in it?

Customer: replied 1 year ago.
Yeah Iv checked for obstructions all clear it must be 350mm long goes through 250mm wall and sticks out 100mm.
I will try turning it down tomorrow to 48 and I may just order the stat as i assume it won't be exspensive , you wouldn't know the part number would you?
