baxi bahama ch not reaching set temperature

[fdead]

hi can anyone help me please by the way i,ve read the posts about this boiler but im perservering for now. losing hair at same time
i have a baxi bahama combi boiler
how exactly does the burner cycle work

my boiler will fire fire up and provide some CH warmth but will not reach set temp on stat
the burners will cut out even though its not reached set temp
pump runs continuosally whether burners firing or not.
i have shorted out flow switch so have ruled that one out.
surely the burners should keep on and heating until set temp is reached .
The stat is calling for heat all the time but the burners seem to fire for a while and then stop, wait probablty 5-10 minutes and start firing again
this is a continuous cycle without actually achieving heating set poinT
no error indication on boiler
Any help kindly appreciated.

As with a lot of boilers these suffer wth PCB problems & theres a couple in there. Bahamas were made in france by Chaufatux I believe, so there best in a skip . built to go wrong . Even baxi say so. ASK gazthepotertonengineer.

Why are you running two threads on this? It get's confusing.
