any other lights flash?? what is your system pressure?? should be betwenn 1 and 1.5 bar
 
Can you hear the fan spinning?

What are the 2 clicks? Could they sound like a spark, or are they more 'heavy duty' clicks like a valve trying to open?

If it is the bottom light flashing, I would suspect the primary ntc (the only one on this model) depending on the answers to the above questions.
