Haier HDHP80E1 Questions & Answers

Have had the haier dryer less than 3 years its been great until a few months ago its has started to make a bad squeeling noise intermittedly throughout the cycle its very high pitched and im am not sure why this should or would be happening brought in 2019

I love my heatpump dryer, had it for 12 months and yes, it takes longer, but no moisture is in the air. However recently it has been releasing lint everywhere, all over the front and when I open the door it is hanging from the seal. The lint filter is empty when I start the dryer and nowhere near full when finished. Wondering if there is something I should be cleaning out? I have checked the little box at the front bottom.
