Load laundry into washer
Load garments in loose heaps evenly around basket wall.
For best results, do not pack the load tightly. Do not wrap large
items such as sheets around the agitator; load them in loose
piles around the sides of the basket. Try mixing different sized
items to reduce tangling.
IMPORTANT: Do not tightly pack or force items into washer.
Items need to move freely for best cleaning and to reduce
wrinkling and tangling.
