Baxi Bahama 100 No CH and cold water only

[dalepearson]

Hiya Guys,

I have searched the threads but not sure i see a matching post. Basically everything was fine this morning. The this evening only cold water, try CH rads remain cold. I checked the boiler and everything seems fine as normal, pressure seems fine, green light is on, orange flame light on, pump running, just nothings getting hot?

Any ideas guys. Thanks

the flame detection light is on but is the boiler firing

Thats what i am thinking? But how do you check? I took the cover off and see a small window? Should I see something in there?

Thanks for your help.

flames would be a start

 

[dalepearson]

In that case i am seeing no flames in the little window near the top of the boiler. Any suggestions? You familiar with this boiler?

 

[kevplumb]

if the window is at the top the combustion chamber cover is on upside down

Ok so its about in the middle i guess, when u look at it there is a round black thing behind the window? Should I see a flame in there?

What steps can I take to get a flame?

 

[kevplumb]

you should
is the pressure ok ?
is the fan running ?
is the pump running ?

 

[dalepearson]

Pressure fine
Fan going
Pump running

But all is cold.

 

[kevplumb]

first thought is
aip pressure switch
this tells the control if the fan is running
by your posts (nothing personal)
you dont know enough to be playing
get a corgi fitter in

I wanted to get an idea of the possibilities to access the cost.
As I hear so many stories about people getting ripped off.

Thanks though.

could check the primary flow switch isnt open curcit
do you have the installation instructions

 

[dalepearson]

Yeah I have all tha manuals.


Strangely everything is working again this morning

 

[kevplumb]

intermittent faults are the worst kind
if you have the book there is a fault finding section in the back of the installation instructions
might give you a pointer
