So far this year I sent that filter to get cooked twice, also the last code I had on the ECM was dpf face plugged.
Thanks in advance.

I removed the mandate otherwise I'd have been replacing it to the tune of $2,000. I think you're at that point. Remove the mandate or purchase a new (not cleaned) filter.

Sometimes when the emissions system faults out, you have to perform a "Maintenence Reset" to get it to regen again.

It also sounds like it had some fault that caused the regen to shut down. You should have taken a picture with your phone and posted the errors that it reported.
