Baxi duo tec 40 combi boiler

[Alison158]

Hi Guys, I'd really appreciate some help. My boiler a Baxi duo tec 40 combi has just decide to pack up and now I have hot water but no heating.
The pressure gauge was 0.5 so I repressurised hoping that would fix the problem but it's still the same; hot water zero heat.
I've tried resetting, turning the whole system off and on, checking the timer and everything in-between. I don't have a users manual to call on, I suspect the previous owners ditched it.
I have no idea what the problem could be or where to go from here. I'm a woman on my own and last time I had a problem with a boiler I was well and truly fleeced and ended up having to buy a new boiler when it turned out that all that was needed was a new pump so any help you can offer would be greatly appreciated.
Thank you.

Could be the diverter valve that was failed. You need a gas engineer to look at this issue.
If it is, it is not a difficult fix.

When you call for C/Heating is the wee radiator flashing on the front of the boiler Alison?

 

[Alison158]

Thank you PBOD, what sort of price am I looking at if it is a diverted valve?
Hi PG, nope, no lights at all when I turn the CH on.

What, there's no flashing Led when calling for heat?
Any 'E' error codes in the wee window?

 

[Alison158]

Lol, sorry PG, hypothermia is numbing my brain, yes there are display windows but when I turn on the CH they don't light up.
Thank you so much for the manuals PBOD.

Do you have a wireless thermostat ? Make/model would be helpfull. First try changing the batteries.

 

[Alison158]

Hi Gigz, I do have a wireless thermostat, it's a baxi and I've changed the batteries.

 

[gigz]

When you turn the thermostat up does the green light come on on the boiler display ? And do you have a condense pump ?

 

[Alison158]

No to lights and sorry I've no idea what a condense pump is

 

[PullerGas]

Have you got it switched to both HW & CH on the selector switch & have you tried to reset the boiler?

 

[Alison158]

PG, yep done all that. It just doesn't fire up.

Is there a receiver unit for the thermostat near the boiler?

 

[Alison158]

Thank you all for your help and input but I guess it's time to call British gas out and hope it's an easy fix that won't cost the earth or results in a new boiler. Thanks to you guys I can at least I can pretend I have a little knowledge so fingers crossed I won't get ripped off again.
Merry Christmas and a happy peaceful amd prosperous 2016.

Sounds like you're stat and reciever need re-marrying. It'll tell you how to do this in the instructions. Google them if you don't have them. You would know if you had a condense pump as you would hear it kicking in every now and again.
