Your problem was that you have drained down the system, with no water in the system the boiler will light up and the boiler stat will sense the temp and shut down. What you did by draining the system and trying to fire/light the boiler up again was VERY DANGEROUS, as if you had a faulty stat, you will have had your boiler flying off the wall and passing through the window/wall. And ruin the seals on the boiler
A bit like turning a kettle on with no water in it and no trip cutoff switch.

Hmm,
As Plumb1 stated not a very good idea at all!
Don't use the boiler to heat your water if you are draining down parts of your sytem for maintanance! It is okay if you remove a radiator by isolating its valves but not when draining down either partially or completely! You obviously have air in the pipes and its not good for the pump or the boiler to run. Your boiler was shutting off on its "overtemperature" thermostat as the small amount of water in it wasn't moving anywhere and it boils in seconds!
Don't do this again as you could blow your boiler up!
