I have seen two print heads in 6 years actually clogged. Both were from outside debris and it took at least 15 print hours for it to show up. I have never seen a clogged head from the factory. They test them before they are shipped, which is why there is filament in the head when you get it.
What I have seen is users who forgot to calibrate the head or had a problem with their printer hardware that lead to a bad calibration or a bad connection. So if your head was clogged from the factory it is the first one I have ever heard of. It would also have been covered under warranty, and if it lead to the later seal failure that would also have been covered.
So something doesn't add up for me. Some information is missing. CEL doesn't deny warranty coverage without reason.
I can't tell when your head was made unless you give the first set of four numbers in the serial number as I asked.
Where did you buy the print head?
