MDB4409PAB1 Maytag Dishwasher - Instructions

Follow the u tube instruction. Replacing the pump was very simple and easy. The hard part was getting the dishwasher out of the cabinet and back in again.

Only one friction sleeve was broken. So I pulled out the dishwasher to see how the one on the other side went on. It was very easy to replace and I replaced both. Unit works fine now.

Husband watched your repair video. Everything went well and we are very pleased.

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!!!

Pull dishwasher out a few inches. Disconnect spring from plastic connector with long nose pliers. Remove connector. Replace friction sleeve. Replace connector.Reconnect spring to plastic connector. This completes repair.

removed kick panel with screwdriver, 90 degree turn of screw. Put towel under drain pump. Disconnect drain hose by loosening spring clip with pliers to provide access to pump. released spring clip on old motor while turning counterclockwise to separate pump from drain reservoir. inspect drain reservoir from inside machine to remove any foreign objects. Installed new pump by indexing attachment flanges to notches in reservoir and turning pump clockwise until locking tab makes audible click. reattach drain hose insuring hose is contacting "stop" ribs on drain hose pipe. Run wash cycle on machine to insure there are no leaks. Re-attached kick panel.

Disconnected the damaged hose extension from the dishwasher outlet drain hose and the connection to the sink drain. Removed two clamps. One a spring clamp and the other a screw clamps. Connected the new extension hose with a spring clamp to the dishwasher outlet drain hose. Connected the other end to the sink drain with a screw clamp. Checked for leaks. Good to go!

I took the valve off and actually hooked 110 volts to the vale and tried to blow through it and it would not let air pass through it. I replaced the the new valve in about 15 minutes and it works fine

Killed the power and shut off the water. Unhooked and unplugged power, hot water and drain connections to move washer to middle of floor for easy access to all sides. Taking out the the main pump/motor assembly (the "Assembly")required taking out the flat white hot water tube that feeds the upper and middle sprayers. So, I started by taking out the two trays. Then, took out the lower, middle and upper sprayers. Then, tipped the dishwasher onto its front and disconnected the hoses and several electrical connections from the Assembly. Also, unhooked the drain pump motor and impeller from the Assembly since these are not included with the new Assembly. Took out the three sliding retainers to release the Assembly from the bottom of the dishwasher. Took a little gentle coaxing to release the seal between the Assembly and the tub bottom. Took the Assembly apart and found that the problem was the shaft bearing (ball bearings) between the motor and the impeller had rusted and subsequently failed. Therefore, buying just a new motor would have not helped. Inserted the new Assembly into place from inside the tub. Because of the tight seal, the Assembly had to be carefully placed into the tub opening and the seal gently pushed into place by working all the way around in 1 inch intervals. Took about three trips around the seal of the Assembly to ensure a tight, even fit. Otherwise, working unevenly around the perimeter will bind the Assembly and you'll have to remove it and restart. Once in and seated evenly in its place, reconnected the hoses and electrical connections. Installed the drain pump motor and impeller onto the new Assembly. Tested the unit for proper operation and leaks. Found no problems. Then re-installed the water tube, sprayers and trays inside the machine. Helps to jot down steps taken to disassemble so you retrace steps to re-assemble.

Rather than just replacing the motor and seal, I figured it would be just as easy to replace the sump and pump assembly also. It makes sense because the extra cost is minimal and I have a completely new unit now. The repair is quite simple. Just three clips holding the sump and a few electrical connectors and the unit comes right out.

Removed dishwasher from cabinets replaced motor which was easy to do reinstalled in cabinets and ran cycle. All was good. No noise and no leaking.

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.

Did the repair, but needed one extra step not described in video:

I followed the directions on the PartSelect Youtube video - very helpful! I do believe the heating element was the original culprit, as it had a "burn" area about the size of a dime that caused it to almost break into two parts. Obviously a point of failure.

BUT - after replacement, it still did not solve the problem of the dishes not drying.

After much web searching, I tried the diagnostic mode on the dishwasher, and that did a hard reset of the logic board and FIXED the problem.

So in all, it required both a new heating element AND a hard reset via diagnostic mode.

The repair was straightforward. The hardest parts were pulling the dishwasher out from the counter and keeping the dishwasher from falling forward when I needed to reach inside. The instructions in the video were accurate. I was very glad I bought the rubber washers, because I could not reuse the washers from the original heating element. Easy enough repair to do on your own.
