not sure how to check system pressure/ air bleeding
 
Turn the boiler back off an on again. You want it to stay in status 5 at least until things start to get hot.

Status 1 means the boiler knows it is supposed to be working, but is too hot internally. Lack of circulation being the principal cause at this stage of the job.
 
Press the boiler's power button.

The numbers in the display are the system pressure - should be between 1 and 2.

There is a radiator style bleed key on the top left of the boiler.
