[Material always stops extruding]

Halo the community,

 

I am on an urgent job and i am trying to print PLA or ABS with my Ultimaker 2+. The problem is that, after a certain time the material stops extruding because a hole has been digged in the filament as shown on the attached picture. Most of the time the material even gets break inside the tube.  I have tried changing the thightening in the feeder setting it on the two extremes but the result is same. 

 

can some one advice, please.

[Nylon model is not sliced on Ultimaker2+]
