Hi, I have an 05 Artesian Dove Canyon. After draining, cleaning and refilling my circ. pump was not working. I was getting the dreaded 3 dots error code. So I called Artesian and talked to Victor who stated there might be an air lock. I did what he said and got the air out, but still no circ. pump. So he stated I probably needed another pump. 
So I ordered one, installed, refilled , bled the air, I think,  and still not working. 
Can anyone on this board help me please!!
