MDB4709PAW3 Maytag Dishwasher

Caviat: The actual repair is less than 15 minutes, but I spent a lot of time playing with it before I figured out it was that easy and fast. You don't need to remove the dishwasher from the counter to do this. And it will probably help to look at the new part closely so you can understand where the retainer clip is to press it and release ... Read more the old pump.

First remove the water from the dishwasher pan that would not drain with a wet/dry vac. Otherwise the water will all drain on the floor when you remove the pump. Then remove the two screws on the kickplate on the front of the unit below the door. Remove the kickplate/maintainence access cover. The drain pump is on the right about 8 inches in. Using two hands you grasp the drain pump with your right hand and use the left hand to push the retaining clip down. Then the drain pump will rotate 1/4 turn counterclockwise and can be removed without pulling the dishwasher out. There is likely to be some water leak out that was traped in the pump housing that you can not reach with the vac. Disconnect the wire. Connect the wire to the new pump, put it in place and 1/4 turn clockwise to install it. Replace the kickplate and you're done.

1) Remove top and bottom dish baskets from the dishwasher, this will give you room to work. To remove top basket there are clips at the end of the slide rails.
2) Remove lower spray arm by unscrewing plastic screw, it should only be hand tight.
3) In order to remove the strainer cover, you will need to remove the plastic tube th ... Read more at takes water to the middle and top spray arms. Unclip this tube from the top and middle clips and then work it out of the strainer assembly tube. Now you should be able to remove the tube at the bottom of the dishwasher by unscrewing it 1/4 turn.
4) Remove the strainer cover by unscrewing the 4 Torqs screws.
5) You will now see two smaller torqs screws that hold the hold the Chopper Assembly cover down. Take these two screws out and remove the two piece cover.
6) Pull out the broken Chopper Assembly, make sure you get all the pieces!
7) Install the new Chopper Assembly. Make sure that you install the Assembly with the small part of the screen towards the bottom of the housing. Also make sure you compress the spring as you install the part. I used a small pair of neddle nose pliers to compress the spring behind the screen in order to install the chopper assembly.
8) Put everything back together and make sure it works!

Rather than remove the pump assembly - as an earlier post had done - I pulled the entire dishwasher out and laid it down on the floor. This allowed easy, direct access to the motor (that was the hard, messy part). From this point it was easy. Unplug the wiring, remove the retaining bolt, rotate the motor off the mounting brackets and pull ... Read more it out. Then put the new one in. That was the easy part (about 15 minutes). The entire job took 2-and-a-half hours, most of which was taken in disconnecting, cleaning up and reconnecting the dishwasher. It's much quieter now.
