Washer leaks only when washing towels

I have a top load high capacity Maytag Bravo HE washing machine model MTW6700tQ1. It has been leaking for around two years, but only when I wash towels. It has a specific towel settling that I use. I have tried full loads of towels and as little as two bath sheet size towels. It will still leak. With one bath sheet it does not. It does not leak with sheets or if I wash a large load of clothing. The leak comes from underneath on the bottom middle left side (if facing the machine). One load will leak enough to make one kitchen towel completely wet when wiping it up, but not soaked. Is this an easy or inexpensive fix or should I just continue wiping it up?
