the dryer rotates only one direction causing the items to tangle and twisted into a huge ball/round  shape each time when we try to dry something.   it doesn't matter whether there was only little stuff or many stuff in the dryer.  it was never completely dry.  it got worse when we tried to dry bedding stuff.  the sheets never  got to dry because the sheets always  turns into a big ball  so the inner side  was always wet.  each time, we had to take the big twisted ball shape out of the dryer to untangle it and put it back to continue drying.  often times,  i have to repeat it at times 2-3  times to have my clothes or sheets completely dry.
