Ideal c24 when switching on the boiler it ignites for 8 to 10 seconds, then it cuts off and the lock out lamp comes on. pressing the reset button or turning on the hot water tap has the same effect. Any ideas?

Hello!

sounds like the control box for electronic ignition is locking out depending manufacture after 1 to 3 times tries! it's not sensing flame @ pilot or main burner or hsi (hot surface ignitor) fyi don't touch hsi ! oil from skin will damage it! or flame rod that needs to cleaned !! what brand of electronic ignition does it have??
i worked a gas utility servicing boilers & water heaters & warm air furnaces for 20 yrs!!

good luck!!

Happy to render my assistance.

This is your problem!

I need to get the make and model of your specific boiler to give you an accurate answer!
Waiting for your response.

Sounds like the gas valve to me you need to see if the appliance is sparking 1st if it is then u need to check wether there is the right voltage going to the gas valve according to mi manufactureres instructions normally 240 volts ac if there is voltage then the gas valve is sticking get back to me after your findings

Hi Harvey,
the make and model of the boiler is Ideal Mini C24
Thanks
