Hi I am thinking what your tryig to say is the air pressure switch?
you can check this switch to see if the boiler works by removing one of the sensing tubes from it & by sucking on or blowing as this willactivate the switch you dont have to do it very hard, just gently as you will hear the switch clicking, if the boiler does fire when you click, in order for it to continue to ignite you may have to fold over the tube, when you release it the boiler should stop.if it does work then you will have to change the air pressure switch, but remember this can only be done by a Corgi Engineer

Kindly

Halstead 102 combi boiler dhw/ch run for 1second then goes off


You might try cleaning the flame detector. It sits in the combustion chamber and looks like a small bent nail fixed to the burmer [usually at the rear]. Use a medium emery cloth and make sure that the gas holes around it are clean and clear of debris

I have a halstead finest gold combi when I turn the boiler on the boiler goes into its ignition sequence when it comes to ignite the boiler fires but after the igniter stops the boiler cuts out completely...


Difficult to get too specific without knowing if you have gas or oil. Also, I am going under the assumption you mean the burner shuts down, not the whole heating system. That being said, all heating appliances have whats called a safety curcuit. Each control has the ability to shut down if certain critera are not met. There is a sensor that senses light down the blast tube. If no light is sensed in a predetermined time period, then the sensor cuts power to the burner. This stops delivery of fuel so if it does ignite you wont blow up.
(I suspect that the ignitor and burner shut down simultainously.)
It may be the sensor (cad cell eye) is doing its job, however why is the question. Could be a number of things including the fuel delivery, ignition, improper air adjustment, etc.
No qualified professional should diagnose a problem unless they are in front of the appliance. I recommend you find a licensed qualified heating techician. Hope this helps.

Halstead Finest Gold Combi Boiler water input temp


I know of no limitations on the temperature of the inlet water for any boiler. The warmer the water, the less energy it will take to heat it to desired temp and the colder the water, the more energy it will take. Extreme temps over an extended amout of time in either direction can stress a unit and could possibly, only possibly reduce service time.
