Can anyone point me in the right direction with this problem.
I have a Baxi Bahama 100 Combination boiler with an annoying intermittant fault.
Occasionally when the heating is working fine and I switch on the HW the flame light goes out and the water runs cold.
When HW tap is then turnd off the boiler clicks a bit but the heating doesn't fire up - I don't think there is any pump flow either
The boiler clicks when I tuen on the HW tap so it is sensing that so I think I can rule out the flow switch.
I am thinking it could be the CH flow switch but would appreciate any help from experts or people who have had this fault.
