If the washer tub is leaning to the back a little, your rear spring where it attaches to the bottom of the frame has rusted off. Just check. I usually just drill a new hole.

I have had washer for 13 years with no problems, and around december 2008 It started leaking water under the bottom front panel intermittently. I put a towel down to adsorb the water. After the cycle is completed the clothes are still not clean. The leak has gotten worse. I have the washer open up and also you can see where water has been running down the back panel from the top plastic unit that let the water into the machine. I think I have sevral problems. I need some help please.
