How can I fix my Bosch Boiler?

It sounds like there is something wrong with the motor. The pilot light is not igniting and the red lights indicating that the heating/water is on are flashing. Also there is no pressure but that may just be because I've turned it off now. Any ideas?

agree you will need to pressurise the system, sounds like you have a CDI so you will need the special T shaped key to do this. Once you have done this reset the red button as it is likely to of overheated and this is causing your flashing light.
