little bit when the washer is not in use. If you don't it will grow mold and smell terrible. I bought 2 quarter size suction cup and I wrapped a small peice of wire around the top of each cup. Next a attached a piece of twine about 5 inchs long to the wire on one of the cups and a put a loop on the other end. I put one suction cup on the door and the other on the the front of the machine. I made a loop in the wire without the string. Now when I finish using my washer I loop the string over the wire . It allows me to keep the door open about 4 inches, just enough to keep the air moving but yet the door is not all the way open where it would be hit every time someone passed it.P>S> I live in Arkansas where the humidity is high.
