MDB7949SDM2 Whirlpool Dishwasher - Instructions

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.

Unplug dishwasher and slide it out from under cabinet. Remove old broken link (a heavy string between two plastic parts) and replace with new one. Slide dishwasher back and plug it in. Very easy and no tools required.

Searched internet found a YouTube video not quite the same model but close enough to get me going and the steps were the same

I did not relize that the drain hose was in two parts. Naturally I ordered the wrong half. So after I relized my mistake, I re-ordered the correct part. Once the correct part was received the repair was easy and went well.

The old tine row came out easily and the new one was easy to pop into place. I was pleased that it was so easy to order a replacement part.

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.

put new hose on, very easy.

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!!

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

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.

Remove the mounting screws that hold the dishwasher under the counter top. Remove dust cover plates at the bottom of the machine. The machine will have to be pulled out, so turn off the water to the machine. Usually under the kitchen sink. Disconnect water supply and push it out of the way so the dishwasher can be pulled out. Pull machine out enough so you have access to the door cables and springs. The door will have to be in the closed(up) position to do the repair. Usually only one side is broken. Start with the broken side and copy the working side when installing new parts. Then repair the working side. To get the working side apart just pull on the spring and disconnect it from the cable. Do the reverse to reinstall.

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

Pulled off old seal. Pressed into groove the new door seal. No parts required.

There was a small tear in the mesh in the accumulator as well as a noticeable buildup of Detritus in the spray arm. I was able to remove the defective parts and install the new items easily. Total time was less than 30 minutes
