    Hi I'm no heating engineer. Anyway my problem is that my boiler will not ignite for either dhw or ch . Tried Reset green ,ignition led flashes for a few seconds cuts out then the red led boiler (shut down) comes on , it sounds like the fan/pump starts , no sign of any clicking noise . Any help would be appreciated before I have to bite the bullet and buy a new boiler.
    Planning on stripping PCB down once I get in to check for any dry solder connections and also the relays.
    Thanks for any help

    ( anyone recommend a good boiler around the £600 /£800 mark for a 3 bed house while I'm at it ) thanks

    Would be worth pulling pcb, and check for broken tracks, burning etc. i had no ch or dhw, but i did have ignition, turned out to be gas valve! Baxi duo tec is a cracking boiler.

    Can't find any dry solder joints , relays not sure what these are but the clear boxes have no sign of burnt marks,
    The boiler pilot light ignites for both ch & dhw but decides to turn off after about 6 sec's then on comes the permanent red led shut down :( .
    Still no wiser :((

    Thanks for gettin back to me , can't see any obvious signs of damage on the PCB , my pilot does also ignite but goes off after so many seconds .
    I put it down to a sensor at 1st as the problem happened a few times leading upto today but I was able to reset and the boiler worked fine for the rest of the day .
    Thanks for the tip on the new boiler I will look into that thanks mate

    I wonder if it could be a faulty air pressure switch.

    Not sure what I did if I did anything that is and screwed it back together and it fired up and is now working I'm not sure what that tells me because I didn't really do anything so I'm still baffled . I think I'm gonna look into that boiler you recommend .

    Back again , boiler still playin up this morning but what I did find is if I reset it and tried the ch it would shut down each time but when I turned ch off and tried the dhw a couple of times ,eventually the boiler would fire up and be ok then I could turn the ch and this then works fine also .
    Any ideas what this could be would it be a sensor or something totally different .
    Any help would be appreciated thanks


    Just ordered 2 new sensors for the ch/dhw not sure if this is the problem but once I've changed these that eliminates them

    Is it worth ordering a overheat thermostat 100c also ?
