My vokera linear boiler constantly errors off with o3 error. The boiler seems to work ok. Can anyone tell me how I can fix this problem. 03 error is fan/flue problem so the book says.

You could start with checking to see if the fan is working and that the flue isnt blocked. Is the fan noisy or does it just buzz or not even move?
If the fan is working and the flue is clear then without looking in the book you could have a problem with the air pressure switch not sensing that the fan is working

Have not checked the fan but have not noticed any noise. The boiler errors off then restarts its self. No problems with heating or hot water. You may be correct with the air pressure switch I will check it out in the morning after work. Thanks for the help I will let you know how it goes.

Its to the right of the fan on the other end of those 'rubber' tubes that lead from the flue.
