After finding out that the impeller shaft was stripped (plastic) I quickly found the correct replacement on partselect.com by using my model number.
You do not have to remove the dishwasher, if you know what is wrong. But, throw the breaker switch and turn off the water! After removing the spin washer arm, Undo all of the torx screws and pull out the plastic filter looking plates along with the center plastic water jet. This jet provides water for the upper washer assembly. You may have to pop that upper assembly out to protect it from damage.
The black impeller should just pull out if the plastic shaft is stripped. Otherwise, unscrew the small torx head and remove the impeller. You can remove the blade at this time and unscrew the plastic shaft by unthreading it while keeping the motor from spinning. (I shoved a screw driver underneath the dishwasher through the motor. Also the motor is just floating on the rubber gasket and can easily pulled out to accomplish this task. It's heavy and has a plug attached to it. You'll see where you can shove the screw driver. This comes in handy while installing the new shaft, because it is metal. Which is a great, long awaited upgrade for the Maytag Quiet Series. Once you find which shaft to use, (which correct inner thread, course or fine), install it with the great directions that come with the part. Putting all the stuff together is not as bad as one would think, there is only one way for it to go back together. After installation is complete, turn water and breaker switch back on. Run a cycle and listen for the washing cycle against the wall of the washer. If you cannot tell the difference, you can unscrew the white lock arm and insert it into the door. Turn it on and watch how a dishwasher works. Get ready to get a little wet. Towels!
