It may just be a loose fitting that might just need tighting up . you will have to check the fittings to find the leak .

can be anything from no flame to no fuel etc can try reset or need to have serviced

Isconnect from the hive ,it has been known the hive thrmostat fails on ideal boilers.

Lockout is a safety feature. Usually a latching condition and needs to be investigated rather than blindly reset. (The Combi has a bit more intelligence.) With the ignition locked out, you can't hi-fire the boiler, so no hot water of either type. The 'L' should also show a code number - check your user manual (google) for more guidance.

I've had a lockout on a non-combi: it was caused by lack of circulation of central heating water through the boiler.... The system boiled and the trip tripped. The pump WAS running, but wear in a valve actuator resulted in the valve feedback saying valve open while it was physically shut.

Replace pcb (circuit board)

your boiler needs a minimum gas pressure of 16 mb to light successfully. if your gas pipe has been extended it has to be able to flow enough gas. it may need upgrading to 28mm for even as little as a metre from the gas meter. if your central heating works ok when the fire is off then this is your problem

most have an overrun built in for a few minutes. if much longer have you got a room thermostat anywhere to turn down
If it never turns off check the switch which controls ON/TIMED/OFF and turn to timed or off. if it still continues on timed then it's the timer

Hi Jurgie,
I'm Harvey, the Master Plumber,
Happy to render my assistance.

This is your problem!
When you are 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.

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