MDB7749SAM1 Maytag Dishwasher - Instructions

Turned off water and disconnected line, then disconnected drain, turned off power and slid dishwasher out and turned turned upside down and removed hold down bolt ( it is a 3/8 head bolt) removed wire from motor and twisted motor assembly approximately 1/4 turn counter clock wise and removed old motor and seal assembly reinstalled new motor with new seal and rewired. Turned washer back upright and removed filter assembly and lower jet arm, removed cover for food disposal and reinstalled disposal blade back on pump drive reinstalled cover and filter assembly and jet arm. Slid unit back in place and anchored down to cabinet and turned water and power back on ran washer through a short cycle to clean any soap build up that was left inside and that was it, it all works just like new.

It was very easy to pry off the old wheel assemblies with a screwdriver and pop the new ones in place. Although the part is called "wheel" it is actually the plastic piece containing two wheels. I thought it was a little confusing to just call it "wheel" as each piece has two wheels. It was an easy repair.

Removed old gasket, cleaned track and replaced gasket-also quit using Cascade pellets and went back to using Cascade powder with a numerical "rating" of 6. The pellets of even 10 caused the washer to leak, obviously too much foam would not float the float to actuate the pump.

Removed the outside stainless, front panel, unplugged the control panel and plugged the new control panel into the ribbon cable. Replaced the front panel and unit works just like new.

Turn off power to unit. Remove all screws from back side of door, releasing the front door panel. There is an electric ribbon connecting the touchpad to the control computer. The release is on the left side of the connection between the ribbon and the computer. Release ribbon, then remove screw in middle bottom of control pad, removing it from unit. On the back of the old touchpad find the 3 to 4 inch plastic box in the middle that removes from touchpad and attaches to new one (the screw that was last removed to release touchpad from unit was on that attachment). Using the middle screw, loosely attach the new touchpad to unit. Connect the electric ribbon to the control computer. Put front of door back in position and put screws back in. Turn power back on. Note: screws require (*) adapter.

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

I cleaned the chopper and screen a few times and it continued to get blocked after a couple of cycles. Replaced the chopper assembly and now it works find.

Removed dishwasher from under the counter and took it to my shop. With the washer on its side, I removed the motor, then the impeller and seal. I then disassembled the motor and replaced the front bearing(purchased separately). This required an arbor press. I then reassembled the motor and installed the new seal and impeller. Reassembled in reverse order. Reinstalled under the counter and made conections. Checked for leaks and proper operation.

I had a repair guide for my dishwasher which helped. First I removed the water distribution system inside the dishwasher and then removed the door panel. Next I removed the front bottom access panel. I placed a pan under the pump and hoses to catch water when I removed the outlet hose. Very important here! One must remove the pressure switch from the outlet port or else you can't get the pump clear of the washer tub. Next I removed the drain pump by releasing the catch and turning the pump counter clockwise. Now for one of the hard steps. I had to remove three pins which hold the pump assy to the wash tub. Two of them are out of sight so you have to weave you hand past all the hardware and "feel" for the back two. At this point the pump assy just lifts out. Remove the motor /pump by removing one bolt and turning it counter clockwise and withdrawing. I put the new one in. Don't forget to put the pump screen in as I missed this and had to redo the job. Reverse all the previous steps being careful to keep the motor guard out of the pump seal area. Use lots of silicon seal grease and check for leaks on first power up. It took me a couple of adjustments to get a leak-free seal.

This was a fairly easy repair. It took me a little over an hour to complete. First I flipped the circuit breaker for the dishwasher; then I removed the dishwasher from the cabinet and disconnected the supply, and return lines. I removed both racks from dishwasher, the lower washer arm, and the plastic conduit that supplies water to the upper rack. I then turned the unit onto it's side, and pulled the three or so cables that went to the motor, along with the three plastic wedges that held the motor in place. I then pushed the old motor through, into the interior of the dishwasher. This required me to disconnect some additional components to get it to fit through the opening, including the large silver capacitor. I then compared the old motor to the new one, and transferred some of the parts from the old motor to the new one that weren't included with the new one. I then pushed the new motor through the opening. This required a second person, who replaced the plastic wedges, while I pushed on the motor. The cables, supply lines, drain lines, and components that wouldn't fit through the opening were then replaced; the interior of the dishwasher was also reassembled.

Followed a video, pretty straightforward. Be sure to clean all the area. My husband used cotton swabs to clean all the gunk.

First i remove upper rack held in by 2 clips at end of metal tracks. Compress inside clips and pull up then slide rack out of tracks.Then remove bottom rack just pick it up.Then i removed bottom sprayer by unscrewing center thumb screw. Then removed feeder tube for top sprayer held in place by 2 ea. phillips screws one on celin of tub and one at back of tub. Move tube to the right which unlocks it and remove. This has to be done to expose 4 ea. star screws. Remove screws and pop screen cover off. You have to take a towel and soak up water to expose bottom of inlets and outlets for water. You will then see the chopper blade with metal screen behind it. It is held in place with on star screw to the left of round top cover. Remove cover and pull on chopper blade which will release it from fingers mated from shaft to chopper blade .While pulling on chopper blade toward front of dishwasher pull up on metal screen it will come out. Clean all food particals out i used a shop vac worked well. Be careful not to drop screws in water inlets. The plastic shaft was broken in half by a piece of dental floss wrapped around shaft. I hope this helps it was not that diffacult just hard to work over door.

My husband pulled out the dishwasher and removed the faulty part and installed the new one. We found info on the parts source website to assist us. Dishwasher works great!!! Someone from the company we purchased it from had replaced it several years ago, and the seal at the bottom had leaked and the motor had siezed because of the water. We also discoved that the water line was severly kinked in 2 places, so we installed a flexable hose. Now my dishwasher is quiet, fills much faster and all this for a fraction of the price of a new appliance. Would recommend this website.

Remove two screws at top that fasten dishwasher to cabinet. Slide dishwasher out to expose the two links that attach the door to the springs. Fit the new links to the springs and door.

New latch assembly improved door closure. However, door latch did not solve problem. There appears to be another problem.
