Ariston Microgenus error code

[barbituran]

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

Boilers under guarantee aslong as it was installed by corgi. Installers should come back to have quick look. Doesnt take long to determine a genuine boiler fault.

Then call ariston.

Sounds like your pump is kaput!

Get on the blower to Ariston!
