Ok so I fit a few boilers, I can handle it. So this lady rings me to say the pilot wont light on her heating. I have studied the book but I cant figure out the flow chart for this beast. This is the notorious Baxi Bahama 100. The damn thing will only show me a green light and does nothing else at all, no fan running, no pump, I have checked the circuit boards as the book says and the flow switches for operation and all seem ok. So if you boys have any ideas they would be appreciated.

Is there power going to the pump?
Has a fuse blown?
I'm assuming theres no HW or CH

There is no CH or HW there dosen't appear to be power to the pressure switch or pump. I cannot see any fuse on either board to check.

The fact that your pump isnt running wth a call for CH indicates
basic wiring fault / fuse
pcb or OH stat needs resetting
pcb knackered.
Try turning the power off on the wall for a few minutes and then turn it back on.
These boilers are a PITA so dont waste too much time fixing it.
Find out if yours is a SIT or a Honeywell before buying parts for it.
Please remember I cant see your boiler from here so don't blame me if you lash out on a pcb and it does happen to be something else.
My official advice is to get a competent CORGI to see it. Last one I saw like that the APS had melted into a black plastic mess. Thats inside the combustion chamber - Corgi only

get back in yer box it will be daylight soon 
Well this morning she rings to say it's working again??? Could it be one of those flow switches playing up??
Cadiz is CORGI registered but not familiar with fixing modern boilers.
The problem is that the Bahama is certainly NOT the boiler to practice learning on.
It was probably not the flow switches because the pump was not running. But just possibly if the system flow was stuck on it might inhibit the pump?
Its probably a boiler to call Baxi for a fixed price repair on. Even the Baxi guys seem to be absent at the mention of a Bahama!

Thanx Agile I will take your advice to customer. I really must get my answering machine to ask exactly what appliance it is before it agrees for me to go look.
I always insist on the exact make and model before i go to see any boiler.
We charge a fixed price diagnostic fee and to get that to work we have to avoid second visits by taking likely parts with us on the first visit.
Its not cost effective if we have to make two visits although that does happen on the uncommon boilers like Keston, Viessmann or Geminox etc. if spare parts are needed. We expect to get over 95% of boilers working on the first visit.
