My Aquabalance boiler does not reach set temp of 190°. It had a code of AO1. Had to reset boiler.
I did change the Iten 140 ignitor.
What should I be looking for now?

  Hello @rafaelb1961,
  Maybe condensate trap blocked ?

  After you make that expensive repair and you still have the same problem, What will you check next?
