MDB9150AWQ Maytag Dishwasher - Instructions

I reversed the tub wheel, cut off the protruding flanges so that the end of the axel pin was exposed. Then using a small socket I placed a split washer over the end of the pin, used the socket to hold the washer in place and tapped it into place with a hammer. Note there is a grove around the circumference of the pin which holds the split washer. This locked the tub wheel onto the pin and it still rolled freely. Unconventional but it worked great.

Removed top retaining piece by turning clockwise to remove spinning spray arm from bottom assembly. Removed the 6 retaining screws from the primary screen pump cover and lifted up. Removed filter and the four pronged piece that spins with the filter. Removed the 3 hex head screws that held the secondary filter assembly & pump cover in place. Removed center screw that held the bottom black plastic piece just above the secondary filter bottom. Inspected the cutter, then started reassembly in reverse for the replacement of new parts and filters.

I discovered that, except for the central tower, all the spray holes were all plugged with I took to be calcium deposites . Using the parts diagram located on this web site, I removed parts. All parts can be removed either by hand, nutdriver or small wrench however you do need a star drive (simliar to an allen wrench) to remove the Pump Cover and Secondary Filter. The Lower Spray Arm unsnaps from the Pump Cover and Secondary Filter. I laboriously removed the deposits from each part down as far as the support filter. The upper spray arm can be removed by unsnapping the hub. the Pump Cover and Secondary Filter is a closed unit so. I purchased a new one. The process is very labor intensive. Next time I am going to consider purchasing all new parts or calling a repair man.

Had service man: stated I would need new motor/pump at $400 complete. I didn't like the interior of new dishwashers. Nothing to lose, so I verified that the motor was working; reviewed short PartSelect video. Ref: very helpful PartSelect assembly diagrams with parts list. THANKS PS! Removed two dish racks (top rack: extend fully and flip the roller-keeper clips. Pull rollers and rack-pins apart) Then I started taking the pump apart all the way down to the pump base (fits into tub with seal - did not replace that seal). Very intuitive - some parts are tight and must be encouraged to come apart; take care of seals and o-rings; take notes of sequence if necessary. Look for parts requiring replacement. Unscrew Spray Tower Lower Extension Nozzle and lift off Spray Arm and two lower spray arm seals - check seals for wear. Unscrew pencil-like Spray Arm Support Nut. Cause: I found a totally-clogged Pump Housing Filter, a bit of steel wool about the size of my thumb (same size as water supply opening in bottom), and small piece of broken glass. Cleaned all parts coated with lime; new Pump Housing Filter (could not clean adequately). Cleaned the screens underside of filter support (difficult) with brush and wire. Replaced o-rings for Wash Impeller and Drain Impeller as a matter of principle. Only alignment requirement is with bottom water supplly hole. Everything works like new now! Recommendation: clean Pump Housing Filter annually.

Excellent site. When the dishwasher started making a loud grinding sound, i thought "oh great -- now I'll have to buy a new one". After searching the internet (I just entered the model number of my Maytag dishwasher), Partsselect.com came up in the search results. I read several postings from previous customers which described the same problem I was having... followed their step-by-step instructions and was able to disassemble the lower washer arm and find the culprit -- a broken wash impeller. Ordered the parts, they arrived within a couple of days, spent 15 mins putting everything back together and I'm now good to go! THANKS PARTS SELECT!!!!! I owe somebody a free lunch!

had to fiddle around just a bit to look at the others and see how these fit in. No tools were required - just snapped into place once I figured them out.

i removed the strainer cover and then removed the discharge assembly. then repeated steps to finish.. parts select was very fast and cheap ordered ontuesday and arrived on thursday. I will recomend parts select to all

my husband took the bottom rack out, unscrewed it where there were screws, lifted up the unscrewed part, took the filter out,cleaned out any gunk, replaced the filter put the part back on, rescrewed it, put the rack back in and it works much better.

Took out the old basket,
Threw it away.
Popped in the new baskey,
filled it with forks and spoons.
Works great!

By the way, my order arrived in one day.
Phenomenal!

First you must understand that the end cap is not a solid piece. The plastic facing you is wrapped over the piece behind it. The separation may be obscured by age. Wedge thin bladed screwdriver into the outside edge of end cap at the bid point, a sturdy hunting knife will probably work better. When you hit the seam, pry it apart and fold it back. Unwrap the part and repeat on other side. The dishracks will easily slide out and in.

The most difficult part is learning how to unsnap the plastic retainers at each end of the steel sliders on each side of the dish rack. Push the end caps to the outside and the plastic inserts will snap open and slide off the ends of the rails in two pieces (note how they were oriented so you can replace them later). The caps must be removed from both ends of each rail. Slide out the basket. slide the rails out. Pull the old rollers off the pins. Place the new rollers into position. A smart rap with the palm of your hand should snap the rollers onto the pins. If you have done it correctly, the rollers will not pull off the mounting pins. You could also place a small block of wood against the roller and use your hand or a small hammer or weight to snap the pins into place. Assemble in reverse order.

I simply looked at the other side (which was still functioning) and put the new one on but in reverse (left side/right side) I also was missing the end stop to the slide and simply popped that in and snapped closed. Two simple parts and 15 mins. solved a whole lot of aggrivation,
without any aggravation! wish I had found this site sooner!

Snapped old ones off and snapped new ones on.

When I tried to remove the hold down screw for the impellar, the impellar broke in half. I actually did npt need to go this far with disassembly as the problem was with water being retained in the rinse arm assembly and stagnating. This was due to calcium buildup clogging the drain holes. Clearing the holes resolved the problem.

Removed 2 each screws from counter top. Pulled washer out 1'. Installed springs and linkage by hand with door closed. Push washer back reinstalled 2 screws.
