Dishes weren't getting cleaned

1) Lower Spray Arm and Pump Housing Filter:
1a) Unscrewed lower spray arm cap. Removed lower spray arm. Removed metal radiant shields from lower spray arm, cleaned them, and snapped them onto the new lower spray arm.
1b) Removed Torx screws from pump cover, then removed pump cover.
1c) Curled new filter into circular shape, interlocking the tabs to connect the ends together, then replaced the old pump housing filter by removing the old filter and then pushing the new one into place in the pump cover. Old O-ring was fine, so didn't really need to replace it.
1d) Re-installed pump cover by aligning the water ports on the cover with those in the dishwasher, then pushing cover down into place, then installing and tightening the Torx screws. If I were to do this repair again, I would replace the pump cover with a new one.
1e) Installed the spray arm by placing the new lower spray arm into position over pump cover, then screwing in the lower spray arm cap.
2) Upper Spray Arm
2a) Removed upper spray arm by unscrewing the snap outlet nut, then removing the spray arm retainer. This way, the retainer is undamaged and can be re-used.
2b) Attached new upper spray arm to snap outlet nut by pushing old retainer through new upper spray arm and into snap outlet nut.
2c) Installed new upper spray arm by screwing snap outlet nut back into the dishwasher.

Grinding noise during wash and rinse

First off, I must give thanks to Partselect.com for excellent service. They had the parts I needed, a Diagram of how the parts should go into the Dishwasher, and shipping was very quick and reasonable priced. Thank you Partselect.com.

After dinner we heard our Maytag MDB5100AWW dishwasher start grinding during its wash cycle. Needless to say we found this quite concerning, as this is not what a healthy dishwasher should sound like. After fiddling around with it, I started researching the issue and found Partselect.com where it was stated the “Discharge Housing Assembly (Discharge Pump Housing)” was a common failure point. After disassembling the “Pump and Motor” section of the dishwasher, it was confirmed that the Discharge Housing was indeed broken. Since this Dishwasher is over 8 years old, I figured that I might as well replace a few other parts as well, since I'm in there working on it.

Following the blow-up image of the Pump and Motor picture;

Unscrew part 34

Pull out part 1

Lift Part 2, which is attached to part 36

Unscrew part 5 (6 of them) from part 4, be careful not to loose part 3, sitting inside part 4

Lift out part 6 and 7

Unscrew part 8 and lift out part 9

Unscrew part 27 (three of them) and lift out part 11

The bottom plate of this part is the broken part.

Now, since we are in here replacing a part, we might as well replace a few other parts and give this dishwasher a little longer life. I opted to replace the following parts as well, being that my dishwasher was over 8 years old and the gaskets were showing some age.

Part 4 – Pump Cover and Secondary Filter Assembly; I replaced this part because food often gets caught inside the filters and will throw off the balance during a wash or rinse, thus putting premature wear on bearings and o-rings. My filter had a bunch of food on one side, and the only way to remove the food was to slit open a section of the filter, thus damaging the filter screen.

Part 37 – O-Ring that goes inside the Pump Cover and Secondary Filter Assembly. O-rings are rubber and do wear with age. My dishwasher didn't even have this o-ring; now it does.

Part 3 – Lower Spray Arm Seal; I noticed when pulling these parts out that the hard water in our living area was making these somewhat brittle. When ordering these, get two of them, as the picture indicates. If you order one, the package only contains one, and not two was the image shows it should have.

Part 11 – Discharge Housing Assembly (Discharge Pump Housing). This is the part that is making all the grinding noise. The new part will show that it is built a little differently. It appears that Maytag figured out the weak design of this part and made the replacements stronger.

Part 17 – Even though I ordered this, you don't need to order this part if you order the Part 10 kit. The part 10 kit will include this o-ring. Because its an O-ring, I replaced it; as stated above, o-rings do breakdown.

Part 25 – Pump Gasket; This part should really be called the Pump Housing Gasket, as it isolates the Pump Housing bucket and the Dishwasher tub. I bought this because my original gasket was looking pretty nasty and was coming apart.

Part 10 – Seal Kit (Motor/Pump) (Motor/Pump Impeller and Seal Assembly), this kit includes several components that if purchased separately would easily be twice the cost of this kit. Again, seals and Motor Pump seals are a good thing to replace when needing to do work inside the dishwasher.

Continuing on from the previous dis-assembly list;

Unscrew part 12 and remove part 14, 15 and 16.

Unroll part 17 (o-ring) and remove part 18.

Unscrew parts 19 and carefully remove part 20, being VERY careful to not loose part 39.

Lift out part 22, which will include the bearing inside of part 22.

Pry out part 24 with a pick (the replacement is in the kit of part 10).

To remove part 25, you must Remove part 12 of the Door Assembly (see the Door image) to reach the motor element.

Next unscrew part 14 of the “TUB” i

Dishwasher had weak drainingf pressure, turned out to be the drain impeller.

After I ruled out a hose blockage I looked in the washer.

Took the washer assembly apart, pretty straight forward, used the parts diagrams on this site for help. Found the drain impellor was jammed with glass and had lost a lot of its fins.

Found exactly what I needed here. Had it back together in less than an hour, and it seems to be working like new.

Diswasher would not drain

1) turned off power to dishwasher
2) removed each piece of pump assembly (one at a time) from inside the dishwasher. I had no repair manual and didn't know that by rotating the lock lever under the dishwasher, I could have easily removed the entire pump assembly as a unit.
3) Reassmebled the pump assembly using new parts and installed in dishwasher.
4) Reconnected hoses and electrical connection
5) Turned power back on
6) Washed dishes... it's as good as new!!!!

Noise after water disharge.

Using the part list (on your web site)as a guide to remove the parts,Part 32 remove by hand turning counter clockwise,remove screws #5,remove parts(33,34,31,2).
Remove #36 remove 4,3,,6,7,,8,9,remove screws#27 then remove #11 which has a plate part of it but broke on the underside (you can't see it in the picture)it will rub on the fins of part#14 during the cycle when dishes are being washed creating a grinding noise.
i Do suggest to replace the seals,38,37,you may coat the new seals with liquid hand soap for easier installation.
