Removal of spinner (it turns the spray arm) on top of pump housing.
I have removed every thing down to what I assume is covering the pump. The three bolts holding it in place have been removed. How do I remove the spinner that sits on top of the housing? It just turns around and I cannot see what holds it in place. There is a plastic cog that is in the middle but it won't unscrew. There are two round holes opposite each other on the spinners side as well as two square holes but I cannot see anything in the holes that would release the part. Once this spinner is removed the housing should lift off and hopefully I will be able to see the pump and what is causing the problem (which is a grinding noise at the end of the pump cycle). Thank you for any help you can give.
Re: Removal of spinner (it turns the spray arm) on top...
If your talking about removing the bottom, main spray arm for the MDB7100AWB, in the middle there's the little hole with a plastic cog, button, whatever you want to call it that you can grab in pull up and spin, but this is just a spray jet and has nothing to do with removing the arm. But, around that hole in the middle is a disc that is somewhat flat and only sticks up about an 1/8 of an inch from the arm, this is what you need to unscrew to remove the arm. It almost looks like part of the arm (especially if it's caked with detergent), but it's actually the screw fastener that holds the arm on. Just muscle that disc, turning counterclockwise, and it should unscrew, then you can remove the main arm unit.
For the top arm, it just pulls straight down and pops out. You feel like it's about to break, but then it just pops out. To put it back in, it just snaps in when you push it in.
Hope this helps.

Hello. The lower spray arm screws down onto the center, round, plastic part (spinner) that has threads on the center portion. It's very loose and spins easily because it uses the water spray to drive it. At the top of the threads, there will be a flat piece of plastic. Set the spray arm down onto the threads. Hold the flat plastic area that sticks out above the arm with pliers. Spin the spray arm counter-clockwise while holding the spinner. It will thread itself down about a turn or so. Snug firmly--DON'T OVER-TIGHTEN the spray arm onto the spinner. Remember, it only uses water pressure to spin so it doesn't have to be "gorilla tight"! I hope this helps you!
have an older dishwasher also and recently my wife also complained
about it not cleaning right... so me being the man I am tried in vain

Dishwasher SprayArms not Spinning
Hey- Two things could be wrong.- clog, or bad motor. Sump screen needs to be cleaned of debris. Removal of sump cover to access screen requires torx bits and some patience. Replacement of pump requires pulling out dishwasher to access bottom. Motors fail when seal between motor and pump fails. Will still operate, but become weaker over time. Parts available- motor about 100$ at appliance parts pros.appliancepartspros. Hopes this helps- Thanks- ED
sounds like the chopper is plugged or broken. remove the lower spray arm by holding tab with a set of plyers and turn spray arm counter clockwise. then where the middle spray arm attaches at the back of tub remove screw. turn the housing on pump to the right side of the machine( its easier to pull top rack out a bit so that whole housing can move) it will turn a little bit to be released from top of pump. then take out the torx screws that hold the housing and filter on. in the sump there will be one or two more smaller torx screws remove those and remove coverings to the chopper. check to see if the mesh is plugged with food and other things. clean. also check to see if blade turn with the motor impeller. if not then the chopper needs to be replaced. good luck
The top spinner part can simply be pulled off by grasping it near its hub and pulling downward. Push it back on and push in the locking clip in the center.
The bottom spinner can be removed, First unscrew the center column. Hold the spinner with one hand, turn the base of the center column counter clockwise. Then lift column off. Then the spinner should lift off of the keyed white plastic base. Underneath it, on the neck off of which you lifted it, are two plastic washers that form a seal (supposedly). Good to clean these to make spinner rotate freely, but be careful not to break them taking them off.
If you want to go farther in, there is the point of a strange shaped plastic nut sticking up into the base of the column. If you remove this, and the 6 torx screws holding the strainer cap, you can get it all out to clean it up (I had bits of plastic bag in the slots of a 4-armed thing that apparently sprays the filter screen), and scrub the washer in the bottom. Remarkably yucky down there in a 10 year old installation...
First, confirm that the holes are not blocked on these arms. (I did not want to assume you have done this.)
Then check the impeller on top of the motor stem for being loose or worn/damaged - to rule the impeller out. If it is fine, then the motor is failing and too weak to drive the spray arms. To answer your question, I think the answer is "They don't make them like they used too!"
These are the spray arms. If both are not operating - are you geting any water through them at all?
If no - then the fault is the circulating pump or control circuit. Not cheap I'm afraid.
Spray arms are usually ok.
If you are getting water throuh them, then remove them (2 clips or a large nut), and rinse them through. Oftem bits of food get past the filter, and end up blocking all the holes. Make sure they are all clear.
removed and disassembled inlet water valve - minature basket filter was clogged with white particulate which felt gritty. cleaned and reassembled and reinstalled. Works fine now. Idiot repairman never mentioned a filter but wanted to replace entire valve at cost of 140 dollars including service call.
sears sux bigtime. And, from my experience with Fixya, so does your service since I never heard a thing since July EXCEPT for an offer to upgrade. Thanks for nothing.
decrete, you want to get down to the chopper and screen. If the screen is plugged up with gunk there won't be enough pressure to reach the top spray arms. Check out the posted pics. Remove the lower spray arm. Rotate the rear feed arm to the right until it unsnaps from the tube going up the back. See the 4 torq screws holding the filter on. Remove them. Lift the filter up. Now you will see the chopper inlet cover. 1 torq screw holding it in. Lift it up and there's the chopper and screen. Catriver..post back
