Ok, sorry to be dumb. If they both come on, what will that tell me? Thanks again for your help

I'll give the green wires a go, not at the boiler now but are there only the two sets of green wires?

ok, struggling. Do you know if there any other bits i might or would need to look at? Could there be a blockage somewhere??

i only tested the dhw microswitch for continuity and it was ok, didn't think to test the primary microswitch???

Hi, My Mums Alpha 280p is fine with heating but won't give out any hot water. I have stripped down the front diaphragm and primary diaphragm and lubriacted/cleaned and they seem to move fine in and out and make contact with the microswitches, but when put back together it has made no...

thanks for that, wasn't sure as reading different posts you can get a bit confused!! Appreciate your help

Hi, We are making a doorway from our kitchen wall through into an old coal shed, which will be made into another room. House walls are solid brick (9" i think), as is the coal shed....two storey house. The opening is going to be about 1.3m, and we have been advised that x2 concrete lintels...

Thanks Burnerman, I did assume a nozzle change would need to be done. I suppose the pump pressure is higher with gas oil due to the viscosity. The tank is empty apart from any dregs left on the bottom, so i'll change the filter and take a new nozzle. Appreciate the advice.

Hi, Wondered if anyone can give me a bit of advice. I am Oftec registered but have not come across this situation before. A boiler (Trianco Eurostar 90) i was at has been run using Gas oil and was wondering how simple it would be to switch to Kerosene? Would the old steel tank and oil line...

I got your back Bloo, i appreciate any advice but i understand that you were ensuring everything was checked beforehand as you never know! And you did mention in your first reply that the work (gas pressures) would need to be done by someone qualified Thanks again fellas!

Thanks for advice guys. mrgas..... I don't think that Blooflame mentioned at any point for me to check the gas pressures myself and i feel most responsible people wouldn't just give it a go. I'll have a read on the heat exchangers - presume it's the secondary that i have to look at. Whats...

I'm in Lincolnshire near Skegness, probably a bit too far for you. I rang the chap who serviced the boiler that is now living in London (he proffessed from the start not to be any good at boiler repairs) and said that he had set the minimum and maximum pressures fro CH and DHW. Have had...

Hi Blooflame, i did have it serviced recently (2months ago) and funnily enough i did take some notice when the fella put his test gauge on the burner? anyway, he said there was 21 mbar and if i remember rightly 8mbar working pressure. The model is a Vokera compact he25 combination boiler...

My boiler keeps firing in and out constantly when we try and use the hot water. It will light for approx 4 or 5 seconds at best and then cut out, then relight, then cut out and so on...... The boiler also bangs whilst doing this, like there is air in the pipes or something. It is a combi...

Hi all, I have a Vokera Compact HE (25kw?) combi boiler which has been fine for the last 18 months since we moved in. All of a sudden we are getting hot water problems - Our hot water will start hot then go cold and then hot again and so on. The boiler also sounds like it kettles when i...

hello, I've noticed that a substantial piece of felt has ripped in the loft, the bedroom below has a built in cupboard with mildew in it and the windows are always wet with condensation not to mention the coldest room in the house. Moved in recently and not sure what can be...
