Do you check for tissues in pockets or anything fluffy or similar on clothes which could be causing it?
Give the drum a good clean then do an empty cycle, a very hot one with a bit of bleach, white vinegar or anti limescale stuff. Lemon juice if it smells.
Make sure you regularly clean out the filter, especially if it has a tumble dryer in.
Get any lint out of the fabric softener drawer and give it a good clean, getting any gunk out with cotton buds.
Try not to overfill the machine, do more smaller loads so the fluff has more chance of getting drained off in the rinse cycle.
