I think you need to clean the filter under the lower sprayer...I had to do that once and worked like a charm afterwords.

Dishes are always dirty, maybe even dirtier after running dishwasher. has hot water, lower arm moves.

Check the outlet holes on both spray arms for clogs. If necessary, remove the spray arms, clean out the holes and empty out any debris inside the spray arms. Verify that the upper arm is turning also.

If the machine does not drain completely at the end of the cycle, the pump drain outlet is partially blocked and you are retaining dirty water for the next load.

You may have a chemistry problem - inferior soap, empty rinse agent dispenser, or extremely hard water.

Improper arrangement of the dishes can prevent some from being washed. Make sure no dish blocks the spray to another.

Frigidaire Dishwasher Professional Series runs loud now and the dishes aren't clean when it finishes its cycle.

Check the water supply line for kinks, check bottom strainer/drain inside to remove particles/trash blocking water from exiting to pump washer motor, be sure no items block rotation of washer heads. Good luck.

The water is not pumping up for spray.....simply just runs in due to regular water pressure. It does pump out and drain.

Hi and welcome to FixYa, I am Kelly. (FYI there are 36 versions of this dishwasher.. the last digits on the model number are important when ordering parts.)
Dishes not getting clean is caused by either a restricted drain, (usually the problem) or larger than usual particulate under the lower wash arm tower.
The restricted drain can manifest itself:
- At the drain pump outlet, (remove hose and inspect drain port)
- At the air gap at the sink (remove cover by lifting straight up then unscrew the inner cap nut and remove the particulate) NOTE the installed position of the upper cap under the nut as it will only go back together in one position)
- At the Air Gap outlet hose connection (remove hose and inspect plastic tubing)
- At the sink connection. This can be either a direct plumbing connection or a garbage disposal connection. (remove the hose and inspect drain connection.)

As far as the lower wash arm tower
- Remove the lower wash arm.... NOTE the stack up of parts... it only goes together one way!!!!
See this link - Check item 4 above link for debris. - Ensure the o-ring item 3 of above link is in place.
- Remove the lower wash arm
- Clean the screen / fingered drain areas.
- Remove the accumulator cover and check in the pump impeller area for a broken impeller or damaged pump housing.
Your parts can be found here:

One more item to check is the Drain Pump (Item 17 of the above link) It should br running when in a drain cycle. If it is not running remove it and check for debris in the impeller and pump inlet. Also make sure the pump outlet is NOT clogged. Once your sure it is free of debris check winding resistance and then check input power to the motor in a drain cycle. Remember that your first checking winding resistance and then input POWER. (Meter switch position change required)

Thanks for choosing FixYa

Water does not drain from dishwasher

Hi and welcome to FixYa. I am Kelly.

I have a few things to recommend that you check.

1. Is the motor even running when it is in the drain cycle? Yes / No

2. Check the air gap assy for obstructions
a. Check the air gap (if installed)
1) Remove the cover (pull up and off)
2) Remove the upper nut (unscrews from the inside of the top)
3) Note the position of the diverter when you remove it.
4) Check for debris just under the diverter (clean as necessary)
5) If you suspect that the 2 hoses that connect to the air gap are obstructed remove them and clean the ports. (Reinstall hoses)

----Reassemble air gap

3. Remove the drain hose from the sink connection.
a. Clear any obstructions
1) most of the time the connection is into the throat of the garbage disposal and this connection port is what clogs from the garbage disposal food particulate build up in the ported hole.
---Reinstall hose.

4. Test drain cycle. (Pass / fail?)

5. If it fails:

A> Remove the drian hose from the motor pump assy
1) Clear any obstructions

---Reinstall hose

B> No obstructions...
1) You will need to remove the lower wash / spray arm and the arm tower in the bottom of the dishwasher and check for debris, a broken impeller housing or impeller.

--Reinstall the wash arm tower and spray arm.

Test drain cycle.

My Maytag Qriet Series 100 Dishwasher won't drain

Check the drain hose connection at the sink drain for local blockage. If ok, you may have to tear down the lower spray arm assembly down to the deck (noting orientation and position as you remove parts). Look for clogged screens and clogged openings in the deck. You can use a vacuum hooked to 'blow' to make sure these openings are clear. Wash the screens in hot water, detergent, and white vinegar to remove water and food deposits. Make sure upper and lower spray arms have open spray holes and no split seams. Hope this gets you running again!

My GE TRITON XL dishwasher doesn't drain completely when problem while running, but there is always some water in the bottom ....any suggestions>

I've had this problem too, and fixed it by cleaning the lower drain basket. But it could also be your pump or drain hose is clogged. To clean the drain basket, I removed the lower rack and spray arm. To remove the spray arm, turn it counter clockwise while gently lifting it up. There's a lock ring that will also need to be removed. (Remember how these parts come off and in what order.) There is a vertical tube that is attached to the upper and lower spray arms that is secured by a hex-screw that you will need to loosen and disengage from the lower spray arm. After this, you can remove the small protection grid then reach in and clean out the gunk from the basket. I ran a rinse cycle to see if it did the trick and sure enough, it now drains. By the way, I am NOT a professional.

Lower spray arm will not spray water

I just had a simliar problem with all spray arms and solved the problem by cleaning the food screen. Basically, it takes water pressure to make the spray arms rotate. Before assuming there is a failed part, make sure the spray arms are getting max water pressure by checking the food screen. Here's how I serviced my Kenmore dishwasher.

The lower arm assembley is removable by twisting the center plastic piece. It's not very tight and should come off easily by twist with a pliers (but gently). Then remove the tubing to the upper arms (Two screws). Then remove the bottom drain cover (4 star screws).

Under the drain cover are two more things to remove. One, a plastic plate over the bottom of the water drain (1 screw). Two cover to the food screen (1 screw). After removng the screw to the cover of the food screen, it will be a little difficult to remove that cover. The side opposite the screw requires releasing a catch with a screw driver. It's hard tell which way it releases, just keep trying different ways until it pops up. The cover may stick a little beacuse of the food stuck in the screen.

Once you have access to the screen, the screen can be removed by pulling on the center shaft (spring loaded) with a needle nose pliers and lifting the screen straight up. (Note: there maybe a blade next to the screen used to braek up the food.)

After removing the screen, clean it (I used a plastic scrub brush).

Reassembly is performaing these steps in the reverse order.

Hope this helps!

I assume you are having spray issues, or a grinding noise. If odor is your issue, go to the bottom of the message.
For the dishwasher pictured above, Open the door. Remove the lower rack.
Push in the tabs holding the upper basket rail end caps and slide the caps up and out. Remove the upper rack. Clean the holes in the upper (or middle) spray arm.
Hold the lower spray arm still and rotote the thumb tab clockwise. Remove the lower spray arm. Clean the holes in the lower spray arm.
Use a small flat screwdriver to release the tabs holding the upper spray tube from the dishwasher inner wall and ceiling. Rotate the spray tube to the right and remove the tube.
Using a # 20 Torx bit, remove the (about 10) small screws holding in the top of the sump assembly. Remove the top section with the fingers all around it.
Using a # 15 Torx bit, remove the screw holding the round cover over the pump suction. Remove the cover (grab the tab sticking off the corner with a pliers and pull up.)
Anything stuck in the sump will now be visible. If the screen is completely clogged up, then the blade isn't wiping the screen clean. In this case, the screen should be replaced.
The screen is removable, but difficult to re-install. If you need to re-place it, put an open end wrench between the screen and the rotating blade to hold the spring compressed. Also, notice the screen isn't round. The flat edges fit only in the slots they came from.

If it's odor or white powder you want to clean out, use a dishwasher cleaning product such as Dishwasher Magic.

I tell every dishwasher customer: "You do not need to rinse your dishes before washing. But you do need to scrape them off."

Good luck!

Good luck!

Whining noise with Kenmore 16032 dishwasher

I had a similar issue, I removed the lower spray arm (had to hold center plastic tab with pliers and then unscrewed and lifted up the arm). Then I removed the cover with the screen filter(4 screws) and then removed the top half of the stainless chopper housing (1 screw). Found that things like cherry pits, elastic bands, bread plastic ties had blocked the water inlet to the chopper and the area around the chopper blade. Cleaned it all up, reassembled and machine works great! Mine was so blocked that I was hardly getting any water pressure to the upper rack.

To clean the drain on the inside of the tub area you must take the upper and lower racks out first. The lower just slides out and the upper needs the plastic end caps removed from the guides. Next are the two Phillip head screws from the water tube that distributes water to the middle and upper spray arms. This just snaps into the tube behind the lower spray arm. Removal of the lower spray arm is a little tricky. Hold the spray arm and with a pair of needle nose pliers turn the spayed sticking up in the middle of the top of the lower spray arm clock wise. Careful, the spayed piece is plastic. Yes you will think it is the other way but it is not. Remove the lower spray arm. There are (4) four # 20 Torx™ head screws that need to be removed. This will remove the water shed cover. Then there is a #15 Torx™ head screw that covers the waste disposal auger and disposal screen. That is where the clog usually is on the inside of the machine making it not drain properly. I would clean all of the pieces and reassemble in reverse. After that you should run the machine twice and listen to make sure that the water is filling and draining properly. This will also remove all the built up soap residue from it not draining properly.

I had the paper from tea bags, a couple of pieces of un-popped pop corn, a tooth pick, two twist ties from bread and a Barbie necklace clogging my machine. Imagine that!
