Combi boiler advice

[dc1203]

Hi,
Sorry this is probably a dumb question but we have just moved to a new house with a combi boiler. One radiator is fairly cold so I thought I would bleed it. so far so good. it hissed and expelled loads of air as I expected but then the boiler started flashing its warning light ... the pressure gauge dropped right down to zero and nothing would work. I pressed the reset and exentually all came back on. I am confused how bleeding a radiator could cause such mayhem. Any advice would be greatly appreciated as if I do that again my wife will beat me to death with a large rolling pin

Thanks.
