I have a Maytag Quiet series 300 dishwasher. Only one of the control buttons works and lights up, and there is water always left at the bottom after it completes the draining. I am guessing that could be caused by it not being level. I need to know why all of the options for different cycles of washing don't light up or work. A guess is that they may have gotten unplugged or if there are fuses inside then maybe they have blown. Any help would be appreciated. Thank you
