The filament can get stuck in the bowden when it's grinded for a reason or another. The feeder can flatten the filament also causing more friction in the bowden tube, i guess it can be increased if the surrounding temperature is high.
Not sure if this was asked already but what is the brand of the filament? Are you sure it's 2.85mm?
I did get a stuck filament in the bowden so I cut the bowden (50mm)... After that I installed all back (bowden, feeder and performed the atomic method as I could see the end tip of the filament got black) and had no problem in my next print.
I am using the PLA that came with the machine. It is the light blue colour.

Maybe heat is not the real problem.
