Duetto heater problem

Hi folks, new on the scene today having just registered on the forum.
I've just acquired a 2000 Duetto and I have problems with the P4 heater. (I note similar issues from another newbie last evening, is there a common theme here?!!!)
When switched on I get a green flashing light at the (top) fan position. When I select the low or high heat positions I get a flashing (6) red light at each of those positions. My manual troubleshooting section says " seek service attention". As I am a complete beginner with all this paraphernalia is there something I am doing wrong or should I seek service attention from other than this forum?!!!
Any info / advice gratefully received.

6 lights means control fault. These are the guys you need to sort it...

Perhaps I can get it fixed through the 3 month warranty? 
£125 is a lot to shell out before I've got the vehicle off the drive!
