just had same problem. this apprently happens if the power supply has been interrupted or you switch the power on and off.
• The boiler runs for 15 minutes at minimum heat output to fill the condensate trap, the display (K) alternates between -II-” and the boiler flow temperature. This occurs every time the mains supply has been interrupted.

Hi, you are having a problem with your add on cards, try to pull out everything that you have add on to you PC, then try to put 1 by 1 and try to turn on. If it beep once its OK, but if it's continue then the add on cards are the defective.
