I had a similar issue.
See my post here: Use your brains!
From what you’ve shared, looks like it is a minor issue that a little bit of TLC may fix. (Again see my post.)
OH and CLEAN your machine!!! Lots of debris in it (great casue for your issue), also a major fire hazard! Medium pressure from an air compressor, a vacuum or even a can of canned air, but watch out for moisture coming from the can.
