Water is leaking under the bottom?

Normally when you have low water pressure and/or cleaning issues, this an indication of a clog in your main wash pump. You will need to remove the lower spray arm and the coarse screen to get to the main wash pump sump. Inspect the impeller area of the pump. This area is usually where accumulations of debris collect and keep the pump from pulling enough water. Things like orange seeds, lemon seeds, bottle cap liners, chicken bones, and jar labels are just a few of the items I have personally found. Although, dishwashers do a good job at removing most food particles, they are not garbage disposals. I bet you will find a clog in the sump somewhere. Let me know if this helps.

I've been having similar issues, and finally realized how to get the arm off (at least for my Maytag Jetclean EQ Plus). It doesn't look like you can turn it, but the "disk" in the center of the lower arm can actually be spun/unscrewed. Take that off and magically everything comes off!
