baxi combi 80e105e?

By bleeding, your pressure may have dropped too much. Check the pressure in the boiler. It will have a filling 'loop' to take mains water into the system and repressurize. Take it up steadily to 1 Barr. if you don't know how to do it at least it should be your problem if the pressure is VERY low - say 0.25 barr or less. There is a safety switch or something which doesn't let the boiler operate if the pressure is too low.
I have a baxi 105 and my pressure guage is under the flap at the bottom of the boiler.
