MDB7949SDE2 Dishwasher - Instructions

followed video instruction

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.

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.

Removed old part and replaced with new 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.

Replaced the detergent dispenser module by first unscrewing the front outer cover from the dishwasher and removing it, then by unplugging the old detergent dispenser, then by bending the metal latch clips outward to remove the old detergent dispenser, then by bending the metal latch clips inward before inserting the new detergent dispenser, plugging the new one into the wiring harness then re-securing the front outer cover of the dishwasher door.

This repair could be done in under 15 minutes but my dishwasher is so old that there was a lot of gunk built-up around the screws that hold the front cover on that I wanted to take my time cleaning up real nice.

The detergent dispenser is VITAL for getting dishes clean. Without it working properly, the detergent will be removed from the wash during the pre-wash/soak function and your dishes will not come out clean. I HIGHLY recommend doing this repair if your detergent dispenser is not working, and I had a great experience with www.PartSelect.com

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 old rack and and removed old rollers and installed old rollers on new rack as they work better than the new rollers sent with new rack

I was constantly seeing small bits of food blocking the spray holes in the upper and lower wash arms. After a bit of troubleshooting, thanks to the included schematic, the only possible thing left which could introduce particles was the under-unit disposal unit. The dishwasher had to be fully disconnected, removed, and tipped-over to access the pump and motor.

After removing the entire pump and motor assembly, it was obvious what the problem was - the filter screen (which is not accessible normally) was totally destroyed. The motor had ripped the mesh screen up, and sent shards of sharp metal throughout the unit. What a terrible design - a non-user-accessible filter which requires disassembly of the entire product to clean.

I replaced the entire pump and motor assembly which was pretty simple. Just use a very small amount of dish soap to lube the rubber o-ring up to make it slide into place easy. Reconnect all the cables in the same place you removed them from.

If you don't mind using some stainless hose clamps, you could maybe get away with replacing a lesser expensive subassembly - but for me it wasn't worth the hassle.

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 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!!

repair went smooth for the grommet. suggest a small of vasoline to ease installation of grommet

Installation was very easy. The online video was excellent and clear.
Thanks

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.

put new hose on, very easy.
