MDB7749SAM1 Maytag Dishwasher - Instructions

Prepared by watching the video. Great instructions. Great.

Disassembled easily as per video. Removed the old latch and installed the new.

Began the reassembly and learned that after ten or more years the small plastic parts used to keep the dishwasher steady had slowly deteriorated to the point that I was breaking these necessary items faster than I was putting the appliance back together.

What was a half hour task became over two hours and the end result was for me to put my tools away and buy a new dishwasher the next day. I learned that if your appliance is over ten years old BUY A NEW ONE!

Great job by the people who make and sell the latch parts for you who own a dishwasher that is only a few years old.

Thank you Part Select.

1) clear out the dishwasher
2) remove unit securing screws from top or sides of DW and cabinetry near the top or under the counter top
3) gently pull the dishwasher from the cabinetry about 20" is plenty, mind the connecting hoses and electrical connection
4) close the door! pull back the insulation from the area of the hinge and photograph both sides - this will save you the pain of going online
5) you will see the cord, the tensioning wheel assembly and the door balance spring on both sides
6) with the door closed to relieve tension on the cord, remove the cord from the balance spring - this can be done w/o tools at this point
7) remove the 5/16" screw from the plastic tensioning wheels and remove the tensioners, cord - leave the springs in place if not replacing them
8) install the door end of the cord to its hook on the hinge, install the new tensioning wheel assembly, install the old 5/16" self tapping screw through the lower wheel and into the outer hole in the frame
9) thread the cord from the door over the upper wheel and lower wheel. the lower wheel has cord retaining tabs to hold the cord on the assembly
10) hook the eye end of the cord to the balance spring and you are finished with the first side - repeat operations for the other side, reposition the insulation and slide the washer back in its cavity - do not forget to reinstall the stabilizing screws in the upper washer frame
11) you've done it!
12) have a cuppa and do your second washer that hasn't failed yet - it will soon.

put new hose on, very easy.

Removed required hardware and dishwasher from undercounter mount. Turned dishwasher on its front and removed the old motor. Installed the new motor and tested for function. Installed once test was successful.

I took the unit apart to find out what was making the loud noise and found the seal on the main pump had been leaking ito the bearing on the motor.

I removed and reinstalled the new gasket per the video instructions, but I found the corners to be much harder to install than indicated. I finally used a large, flat, dull screwdriver to carefully push the gasket all the way in, and used my fingers to feel whether the gasket was all the way in. I figured if the gasket wasn't all the way in, I would have a leak at the bottom of the door because the top of the gasket would stick out farther than the bottom, which is exactly what the original symptoms were. Perhaps I didn't need a new gasket? There was no visible damage. Pushing in the corners of the original gasket may have fixed it, but the new gasket worked perfectly! Thanks, Part Select!!

Remove 2 screws on lower baseplate. Remove 2 screws that hold dishwasher inside cabinet( may be attached to counter top or side cabinets). Turn off water supply to dishwasher. Remove any connections such as water supply, electrical connection, or waste water line that prevent dishwasher from being pulled out about 3/4 of the way. With the dishwasher door closed, remove broken parts and replace with new parts. Pull on spring to make final connection of nylon cable. Reverse the above instructions for re-installing the machine.

Turn off breaker to dishwasher.
Remove lower basket.
Drain any water using a wet vac.
Remove bottom cover plate. Should be 2 plastic screws using flat head screwdriver.
Should be able to reach pump. Turn counter clockwise to remove.
Disconnect plug wire on pump.
Install new pump by turning clock wise.
Reattach wire plug.
Run a wash cycle with empty dishwasher and check for leaks.
Replace cover plate.
Done.

Removed the old hose, after loosing metal looking rings. Installed new hose ad finally tight firmly the looking rings, using wrench and socket.

Hardest part was pulling dishwasher away from cabinet, making sure to not disturb water and drain line. I replaced both door springs which are on the two sides and attached to the dishwasher frame towards the back. This necessiatated pulling the dishwasher about 2/3 out of cabinet. After attaching both springs to frame, replacing the balance kit was a breeze .One screw to remove and then replace with new pulley unit. Attach the supplied cord with attached fittings to spring and then around two pulleys and mounting point on frame. Done . Push dishwasher back into cabinet, reattach two screws to underside of counter. Probably did not require new springs as they seem heavy duty and were not broken upon examination but ordered them also and replaced just in case. Most problem would be with broken cord in balance link kit

disconect water supply and drain hose, unscrew 2 screws hoding front of dishwasher to countertop, slide dischwasher out so you can tip on its door and remove 1 screw hidden behind plastic shield and pull motor out install in reverse order.

Be sure to shut off power at circuit breaker and disconnect drain and water supply. Remove the dishwasher from the cabinet, lower it on its side. Remove three electrical connections from motor to various sensors. Remove three plastic wedges that secure the motor gasket to make a tight seal. The motor pops into the body of the dishwasher for removal. The replacement motor goes in just as you took it out. It took two people to set the motor right to ensure the good seal on the gasket for re-installation. Then turn it back upright and secure it in place. Couple suggestions, be sure to have ample towels around for leakage from water and drain lines. Be sure to cover the bottom of the dishwasher during disassembly and reassembly of the wash manifold. I dropped a screw in there and it took me some time to fish it out.
All in all, it went well. Don't pay a plumber for this job. I'm a clod and if I did it, you can.

Removed old part and replaced with new part

The video included with this part is perfect. Unplug the dishwasher, take off the front trim piece, remove the drain hose from the pump, unclip the power, press the little clip that holds the pump in while turning it counter clockwise to remove. Then just do that in the opposite order to put the new one in. Just make sure you hear it click when you twist the new one on so you know the clip has engaged. Super easy.
