If the arm is rotating freely when you give it a push by hand, then the problem is blockage in the jets in the arm - the arm only rotates with water coming out of angled jets at the end. take arm out, spray water in centre hole and whatever is blocking the jets should become visible. prize out with a paperclip or similiar

My hotpoint aquarius is leaving dirty residue after the full cycle - do I need a new dishwasher?


The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.

Remove the bottom strainers plates and make sure that the outlet pipe is not kinked, that there is nothing obstructing the pipe or the pump or selector valve. If possible back flush through the outlet pipe and try draining the machine once more before using it again.

Top spray arm does not turn during wash or turns slightly..it is free of clogs and spins freely by hand


It will spin freely by hand, but needs to spray water out of the jets at the trailing edge of the arm. Check inside the arm for blockage and make sure that water is getting to the upper arm from the pump.

Kitchenaid dishwasher KUDP01IL upper spray arm not spinning although water supply appears to be adequate (water sprays from jets but the arm remains stationary).


Just had the same problem, and fixed it. Spray arms turn with proper water pressure in the pipes. 3 reasons can lower the water pressure. 1-pump motor losing power (wasn't my case) 2- cracked pipe (wasn't my case either, pipes, although plastics, seem to be very solid) and 3- debris in the pipes/filters. (It was my case) At first, it looks difficult to reach de filters, but it isn't.
1- Remove both baskets, the top one by removing the front plastic cap on the rails.
2- Remove the "+" bottom spray arm, by unscrewing counterclockwise (if I remember well...) the plastic screw dead center of it (use your fingers.)
3- Remove the three screws you see, but don't try to remove the filter part right away because there is a 4th screw under the leading water pipe, the one leading water to the top spray arms.
4-To remove the 4th screw, you must remove the plastic pipe that connect with the top spray arms. Easy. It's beeing held there by two clips, one on the back wall and one on the top wall. Just spread them with your fingers (or screwdriver) and turn the pipe toward the right side, to free the bottom part of the pipe from the middle/bottom spray arm holder, you'll have to bent it a little so it passes over the heating element.
5- Remove the last screw. Now there's nothing holding the bottom part anymore. just remove by moving it back and forth left and right (to loose it up), be carefull not to lose the clear plastic washers on the main shaft when removing. Now if your dishwasher is like mine (should be) you should see a lot of debris that couldn't reach the chopping device. In fact, the water couldn't flow properly because of all the debris stocked there by the bottom drain filter. Patio screws (?) small chicken bones, etc...
6- If you can find something to pump the water resting at bottom there, (I used a Prestone coolant tester!) you'd have a better view, and could remove the single screw holding the chopping device cap in place. That's the last step. Notice that the chopping device cap, even after the screw is removed, still look like firmly attached, like "glued", but there's absolutely nothing else holding the cap. Just shake it with your hand and it will eventually come off. Now you remove all the dirt/debris you see there, and then follow thw step back the rebuild the washing machine. On my part, it brought it back like if it was brand new..., but, now I'm being a little more carefull about the stuff I'm putting in there...
I hope it can help, English is not my first language.
Good luck

Dishes constantly come out dirty.. What temp should the water be while the dishwasher is running?


Supply water temperature should be above 120 degrees F for effective cleaning. Run hot water from your kitchen sink (your dishwasher should be tapped off the hot water line near your sink faucet) right before you start a dishwashing cycle to make sure it's as hot as it can be when the dishwasher begins filling. Also, during the wash cycle the heating elements at the bottom of the tub may turn on and warm the water further even if you select a "No Heat Dry" option causing a noticeable shot of steam to escape if you open the door during a cycle.
Note: I recently had a problem with our dishwasher (Frigidaire FDB834RFS0) causing dishes to come out dirty and the detergent dispenser to be left with undissolved detergent. Our problem happened to be caused by a partially clogged strainer in the water supply valve. (I would imagine Whirlpool most likely has some kind of filter/strainer in its water valve as well.) When the supply valve was commanded to open for some time, I noticed the water level in the tub would barely be visible below the lower spray arm. After cleaning out the strainer (required removing and disassembling the water supply valve) the water level was noticeably higher -- almost at the bottom of the float or about an inch below the heating elements. Our dishes and the detergent dispenser are now clean.
If your water supply is ok, I would next check to make sure your spray arms do not have any plugged holes and that they rotate freely. Also, use a good quality detergent and a rinse aid. We prefer liquid Cascade and Jet Dry. We have had problems with old, stale, or really thick liquid detergents and by getting a fresh jug have solved the dirty dish dilemma.
Make sure to clean out the filter basket at the bottom of the basin below the lower spray arm occasionally as it can clog and cause the pump to starve due to lack of water. If the pump can't get a supply of water to pump to the spray arms and nozzles, your dishes will not get sprayed evenly and you will end up with them being poorly cleaned.
Hope this helps you out...good luck!

The top two water water arms do not spin


These spray arm will only get water several times in the wash and rinse cycle. They do not turn at the same time the lower (bottom large spray arm under the bottom rack).
There is a chamber that diverts water either to the bottom sprayer or to the top sprayers, not to both at the same time.
If your top spray arms never get water, then there must be an issue with that chamber motor to divert the water. A new sump assembly that has all the new parts.
Good luck.

Water coming out of bottom during run cycle


Your lower spray arm is broken, allowing the water the hit the door where it shouldn't thus causing the water to blow out of the door gasket. To remove you turn the center plastic screw in the middle of the spray arm clockwise while holding the spray arm stationary. You can obtain the spray arm either at you local appliance dealer or at repair clinic dot com.

Kenmore Elite Ultra Wash Dishwasher - top rack arm not spinning


Hi: I just posted a similar problem, but found a solution. After taking the arm, etc. apart (and verifying no blockages), I thought maybe the lack of water pressure was being caused by the fact that there are TWO holes for the top spray arm (higher and lower rack setting) on my model. ie. that water was being forced out of both holes, causing a drop in water pressure, which was causing the top spray arm to stop spinning. I plugged the unused hole with a wine bottle cork (to keep the water from spraying out the unused hole), and voila, it now works.

I wish all appliance fixes were this easy...!

Bottom rotating arm doesnt spray water but top arm does


i have a similar problem. water is not reaching the bottom spray arm. there. i have an underwater case for my digital camera, so i'm going to put a torch or 2 in some waterproof bags and remove the bottom spray arm and run the dishwasher to see if there's water coming out of the bottom pipe, if not, i need to try and see if there's a blockage in the system, or a dodgy valve, could be that the soldering's or the control panel's buggered.

arms should turn freely. spray arms are only rotated by water spraying out from angled jets at end. check for blockage in spray arms - sweet corn and rice are the worst offenders. take spray arms off and run water in centre hole and see it runs out of all the jets freely

Dishes not getting clean


Yes I had the same problem and just fixed it for $7.00. Did not even had to take anything apart. This is what you will have to do. If this dosen't work then try what these experts are suggesting. Please follow these steps for optimal results. #1 Break off a plastic Tea spoon. #2 Put it in place of a LATCH to by pass so you can watch the operation of the dishwasher.(put down some towels for water spill) #3 start the dishwasher on normal cycle. #4 Pour in Gallon of White Vinegar($2.00) while the Dishwasher is being filled. #5 Let it run through its cycle. After the cycle is complete water will drain out and then actual cleaning cycle will start. Then #6 while the dishwasher is being filled again pour in 48 OZ or bigger bottle of CLR (Calciam Lime Rust) it is available at Meijer, walmart, Rite Aid, Home Depot Ace Menard's etc. for $5.00. sit by the dishwasher and listen for it. if you hear water draining pull and push the water plunger so it won't drain so you don't loose your CLR down the drain. since you have the spoon in the LATCH your dishwasher will always be on so BE CAREFUL when you stick your hand in it. And after the cycle is complete enjoy your NEW DISHWASHER.
Thanks
