Hi.
My boiler display shows me all the time A 03 code. I checked the Ariston Microgenus manual and this code says "The heating flow temperature exceeds 103 C degrees during operation" . What does it mean? I tried to reset the boiler but then it works only half a minute and start showing error code again. Boiler has worked non-stop since November 2007 on maximum central heating power.Do I need to call for boiler engineer or maybe I can repair it myself?
Thank you for answers. regards PEter
