Want to clean out hard H20 deposits -how do bottom element?
I unscrewed abut 8 screws to remove the top round thing, but can't figure out what hold bottom circular thing on. I can feel all he muck and disgusting stuff under there with my finger, so I know it need to come off to clean under there so water can circulate.
I can't seem to remove the piece that looks similar to a rulette wheel (which is full of slimy food debri) either. There is a gray plastic bolt that looks like it turns with a metal 1/4" bolt in the middle of it but these parts are not moving either way and it very difficult to hold onto the gray plastic bolt as the whole unit spins while trying to remove the metal one. It looks like this piece needs to come off to access the underneath to clean it.

The arm spins on a tube that is held by a round screw that should only be finger tight. That tube is screwed into a boss on the bottom of the dishwasher. You can do two things.
1. remove the whole lot and then unscrew the top screw by holding the tube with grips and another set of grips on the top screw.
2. Tighten the screw on top until it becomes firm, and then unscrew it.
If the dishes are not coming clean it may be that the jets in the spray bar are clogged with fluff and debris.
If you have hard water, it is likely that the sprayer in the bottom of the dishwasher has become clogged with hard water deposits. This may be the case, even with soft water.
On most models, the sprayer looks like a propellor, and can be removed by carefully unscrewing the fastener at the top and carefully removing the sprayer. If you have a digital camera, I recommend taking pictures at each disassembly step, so you know how to put things back together (in the reverse order that they were removed). It should not be too difficult to remove it, but you may have to gently work with the fastener at the top to get it to budge.
You will need to clean all the spray holes and ensure that none are clogged. I used an ice pick and toothpicks to clean out the holes recently on my dishwasher. (We have hard water).
You may need to soak the sprayer in vinegar overnight if you're not able to completely clean out all the holes.
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
to clean the things... Bought new spray arms online and installed
them in minutes...now the thing works like new... However I have also
found that if the heating element goes bad then that also can mess
things up bad... So I would buy new spray arms, and also check out
the heating element to make sure it is working... Here is a tip that
will help you with the online buying...
We have been having issues with our model where there is dirty sand deposited inside of glasses and dishes. You need a torque wrench for a triple square torque screw to unscrew in the bottom filter to take it off. I would say about 4-5 layers of items to remove- but remove these and clean them out as well as the top blade which should pop right out. Food particles can get stuck in there also.
i have an lx 30
i think its called a breaker fill valve
hobart sells a rebuild kit thats pretty easy
1str unscrew 2 screws that hold cap on and save
with pair of plyers or channel locks unscrew top where 2 screws were screwed into,counterclockwise,
should be a plastic plunger, with rubber seal, rermove and replace with new one from kit, use grease to grease shaft
make sure you have kit before you attempt this.
if you have hard water deposits, clean those areas best you can,on top nut, also if your lx has a booster heater, hard water will cause havic and expensive repairs, a water softner from the yellow pages , will be your lx s best friend, and their not expensive
Top: Remove the upper tray by releasing the clips on the ends of the runners. (Squeeze the top of the clip and pull upwards). Remove the spray arm by holding the round plastic clip that holds the arm and turning the arm. It will unscrew.
Bottom: Grab spray arm in centre and pull sharply upwards to unclip.
You may think this is strange, but I am 99% certain that your main problem is a failed heating element in your dishwasher. Pretty bold statement when I don't even know the Make or model of your dishwasher.
After you pull the lower basket out, as you look beneath the wash arm, you will see screws holding down the top of the filter shroud. Take a picture of it with your snazzy cell phone camera as you remove those screws and as you lift things out - for reference when you go to put it all back. While you are down there, feel the entire heating element "circle" Note any breaks and "bubbles." Remove all the debris but watch out for (sharp) broken glass! If you do not see obvious damage to the heating element, reassemble the filter and test. When you see the poor results, a heating element is the root cause. A replacement element cn be ordered and changing it ~may~ require you to pull the DW out (or not) depending on the make and model.
If you are not up to changing the element youself, the service guy can do this.
Good Luck! Please report back with what you find, OK?
time for a cleaning.. dont worry.. its pretty easy (but gross and probably full of broken glass)..
1) switch the breaker off at the panel
2) remove the baskets and unscrew the plastic thing holding on the bottom wash arm (remove the wash arm and check it for debris)
3) remove the top washer water feeder (there should be little clips that unclip it from the inside of the dishwasher).. and then it twists clockwise and pops out
4) you'll need a med flat head or better yet a star screwdriver set for the next part
5) unscrew the screw(s) holding down the plastic cover that covers the water pump intake inside the dishwasher.. this should expose a 'trap' at the front.. BE CAREFUL
6) start cleaning that out.. there should be everything from GLASS, to olive pits to cherry pits etc etc down there.. get it all!
7) while you're in there, there is another (delicate) cleaning task with the food grater/processor inside.. there is another screw that once removed, allows you to gain access to the food grinder.. there's probably debris in here as well.
8) once you've cleaned that out, take care to line up the grater into the right channel before you reinstall everything..
9) put everything back together, and run an empty load on hot with hot dry and it should be waayy quieter.. (and you'll be surprised at how clean the glassware is).
you should have two filters. one you can unscrew .its a smaller round looking filter right under the bottom spray arm .once removed you just pull up on the flat filter that lying on top of the sump area
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.
