MDB4709AWB2 Maytag Dishwasher - Instructions

Used bowls in upright position in upper shelf determining no water to upper shelf after running in rinse cycle. Added a cup of Vinegar in rinse cycle. Performed bowl test in upper rack & still no water in bowls. Dismantled inside of unit by removing both spray arms & found lower seal deteriorated & upper seal in need of replacing. Replaced seals & redid bowl test & found no water getting to top rack still. Found utube vid showing removing garbage disposal portion of unit. Requires removing screen in bottom of dishwasher. One screw attaches garbage disposal cover. Found non food items & food by broken garbage disposal. Repaired disposal, removed debri & reinstalled all components. Redid bowl test in upper shelf & bowls were overflowing!!????Dishwasher works GREAT now & can hear garbage disposal operating along with massive water being sprayed!!!

At first, I figured the noise was coming from underneath, and took off the bottom front plate. I noticed there was a leak from the center of what I later learned was the "pump" assembly. So I unplugged the dishwasher, disconnected the water and drain from under the sink, unscrewed the screws holding it under the counter, and pulled it out from under the cabinet. Then I laid it on its back, and realized where the leak was coming from. At this point, I thought the noise had been coming from the motor. So I detached the motor (required use of a socket, and realized it was "free", so thought the problem must be further up inside. Reached my fingers in where the motor mounts and found part of the chopper assembly. The "chopper" had torn itself free from the screen. Realized at that moment I needed to disassemble the pump from the top. Took off water distribution system, bottom water rotor, pump plate (required use of "star" screwdrivers, two different sizes), foreign object plate, and chopper assembly cover. Getting the chopper assembly cover off was hard; had to pry it with sharp l-shaped poker; it was adhered with calcium deposits. Finally got it off, found rest of chopper assembly (screen with hole in the middle where chopper had been), ordered chopper from PartSelect, took 3 days, installation was easy, the reverse of removing it. (It is not necessary to remove motor to replace chopper assembly.) However, it is still leaking from the bottom, and I'm at a loss as to how to fix that.

Long story short, noticed one of two leaks and came to conclusion there is no workaround since sump pump gasket seems to be hermetically sealed to sump pump. Which is understandable because of water in area. Wife helped by soaking other parts that were removed and replaced, because of calcium buildup. Which we hope will extend life of dishwasher. I put 1 to 2 hours because I took my time and made sure all parts fit correctly and were back in their original place. Didn't want to take any chances in not covering bases. I am no expert, but definitely a diy'er. I believed I saved myself anywhere from $200 to $300 in labor costs by repairman. By the way, thanks Parts Select your info and site are awesome!!! The second part I had to order was the water inlet valve and your phone representative was a big help over the phone, please don't eliminate those positions. Overall total price of parts approximately $130 w/delivery. Well worth it, since a brand new halfway decent dishwasher starts at $550.

Very simple just remove the rakes and then unscrew the covers and pop out the old chopper assembly and replace with the new and then just put all cover back and it works great.

The cause of the problem was that the chopper was worn out. As a result, the chopper screen was clogged with unchopped food bits. This severely reduced the amount of water getting to the circulation pump/impeller. This was what caused the spray arms not to spray. As a result of replacing the chopper, the dishwasher now works like new.

As far as how I did the repair, I followed the excellent how-to video provided by PartSelect that you can access when you click on the Chopper Assembly from the Pump and Motor Parts diagram for this dishwasher.

Followed the YouTube video linked with the part ordered and it was an absolute dream

All parts were really easy to replace. I just followed the video for each part.

Removed bottom sprayer by turning thumbscrew clockwise approximately 2 turns. Disconnected pipe that feeds upper sprayer by twisting approx. 1/4 turn in CW direction. Removed 4 screws that hold the bottom plastic plate. Removed 2 screws that hold plate on bottom of unit that also holds the choper assembly cover down. Pried off chopper assembly cover and removed broken chopper assembly and replaced with new. Reassembled all parts in reverse over described above.

Just pulled the old gasket off and started on the bottom of both sides of the door installing the new gasket and finished at the top in the middle.

Followed the repair video supplied by the site

removed old door gasket, cleaned gasket groove, and than started new gasket in both corners working my way to middle top of door, made sure gasket was in groove properly w/my fingers. problem solved

Could not take apart the upper rack on my whirlpool dishwasher to replace its wheels to transport its upper rack. The received parts did not match the old ones. Called parts and they suggested these new parts remanufactured and changed from the old ones but they had not been notified. Brought to professional mechanics and they figured it out. Bullshit parts company!!
