Our Maytag dishwasher (E39927 type 779-0) stopped working properly. We ran it and not everything came out clean so i thought we didnt put enough soup in. so we ran it again and this time it didnt drain properly. There is still water sitting in the bottom of it and it's been over a week. How do i figure out how to drain it? Maybe it's clogged. Im not sure where to look to fix it tho
