MDB7949SDM3 Whirlpool Dishwasher - Instructions

All you do is pop out the old wheel unit at two (2) points on the plastic wheel housing and pop in the new one. Easy fix. Less than a 5 minute fix.

First off, this part does not look like a seal. It seems more like a trim piece. It is the only part along the bottom of the DW door so it is indeed a seal, and the DW was leaking after I replaced the seal around the tub and the door. First take off the inner panel of the door by removing the Torx screws on the edge and the hinges. Pay attention to which hole each screw came out because they are different lengths. Gently separate the inner panel being careful with the wires going to the detergent dispenser. The seal is held on by 5 small hex head screws on the bottom of the door panel. Remove the old one and install the new one. Put the door panel back together and on the hinges. Good luck.

Simply snap the old one off and snap the new one on. Simple as that less than 15 seconds.

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 bad wheel sets using screw driver to help pry broken part loose. Then just snapped in replacement. Took less than 5 mins. Now it works great.

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

followed video instruction

saw big hole in first (main) hose - got replacement at local hardware thinking it was the only problem - it wasn't - turned on the water and noticed another leak so ordered hose from parts select - fast delivery - installed 2nd hose but still a leak so ordered grommet from parts select - again prompt delivery - installed it and voila no more leak -
also checked for rat entry points, plugged those and put down bait - bait wasn't being taken under dishwasher even tho rat reappeared so put a snap trap in back - no luck so far - teachable moment: might have been cheaper to just get another dishwasher as parts are expensive and its difficult to tell extent of damage - luckily i only needed 3 parts = $150

Very easy to repair with the replacement wheel assembly. Popped out the broken one, popped in the new one. Price was nothing compared to having an professional repair person come to the home. Glad I found you on line!

all 4 wheel units needed to be replaced, popped them off and installed need wheel units in roughly 10 minutes, no tools needed.

I simply had to hook up the power cord to the dishwasher so i could plug it into the outlet rather than direct wire the appliance. Everything went very smoothly. Everything needed for installation other than tools was provided. Easy to follow instructions if you know a little about electrical wiring.

watched video took less than 5 min to replace veeeery easy to do

With a little pressure, I was able to push off the broken wheel pieces with my thumbs. I was able to snap on the new wheel pieces really easily.
This job took less than 15 minutes to replace all 4 wheel pieces.

I opened the package took out the replacement part and installed it with no tools. Easy, done in 10 minutes.

These wheel assembly that came on the lower rack of my dishwasher were junk! They started falling off within 6 months. I put them back on to the point that the pin in the center of the wheels would no long stay in place, thus the frustrating situation of the wheels falling off often.

Assembly was easy peasy!
