You have what sounds like a fault on your boiler.
Water coming out of the pipe outside when you turn the red knob which is the pressure relief valve, and the pressure in the system has gone down, your boiler will have a pressure switch which will stop the boiler coming on with low pressure to stop any damage to the boiler. Try topping up the system see what happens, should be between 1.5 bar and 2 bar.
It could be a number of things, and without knowing the make and model it would be difficult to make any suggestions.
Best to have a look on Corgi’s website and look for an engineer near you.

Hi,mine has a re set button if yours does too ,just press it. then you should get heat very soon.Usually the re set button is orange,so if the orange light is on then that is the problem.

Assuming the pilot light has just gone out, you just need to re-ignite it. There should be a switch or button (probably piezo electric), just turn or push this button and you should be back in business.
You should check to see that there is power to the boiler in the first place so check your fuses!
If you are still stuck, check the instruction manual for your boiler. If you no longer have it, check on the Internet for the model number.
