How do you remove the spray arm to get to the impeller in the pump. model HDA150X66WA I found some cherry pits floating in the bottom and assuming that a pit got in the impeller. Thanks for your help

USUALLY, there is a knob that holds the spray arm on the shaft coming up from the pump. Hold the spray arm and turn the knob the opposite direction than what the arm rotates. there might be a blockage in the shaft which can be seen when the spray arm is removed. the other blockage might be in the inlet to the pump which is on the bottom of the pan where there is a removable screen below which you can see the food/ debris grinder and below that the impeller to the pump. clean out both if you can. Caution - dont leave any screws/ hard items in the impeller cavity.

The first thing to check is whether the spray arms are clogged up. Small, hard food particles such as pepper seeds can block the holes. Some spray arms can be removed very easily for cleaning. Our old Kenmore spray arm needed a star-shaped bit. Check the overhead spray arm as well as the ones under the racks. You might also try running Lime-Away through if the inside looks clogged up with calcium deposits.

In our old Kenmore, we had food residue on the top rack when the grinder blade was chipped, broken or obstructed by an olive pit, a date pit or a cherry stone. Don't know why the top was worse than the bottom. A new one cost about $25 at that time and was not to hard to replace, but it is a poor design, since it is nearly impossible to keep such things out of the dishwasher. We replaced the grinder three times in 5 years.

Even though modern dishwashers brag that you don't have to rinse first, it is helpful to knock off seeds and pits that can cause trouble. To save water, have a small vessel of water--perhaps a pan you are soaking--and use a brush to quickly swipe each plate or bowl before loading.

The first thing I would do is unplug pump and disconnect discharge pipe. Then remove pump from pit and check float switch to see if there is anything catching on it that would stop pump from running. While you have pump out of the pit you can wash it off and spray water around base to clean inlet to impeller, also clean float assembly. Install pump and hook up discharge pipe and plug it in. When you put the pump back in the pit make sure that it is sitting so that the float is free to move. If you don't want to remove and clean pump then make sure that float is free to move where it's at. I hope this helps you. Thanks

Hi there,

Well some small fruit pits, toothpicks, and fragments of glass sometimes get stuck in the pump. When this happens, open the pump and remove the debris. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. 
To get to the pump, you usually need to remove the lower rack, the spray arms, and the spray arm support from the inside of your dishwasher. A dishwasher pump isn't obvious. Look for an impeller a round, plastic fan blade-type device that spins around and pushes the water toward the drain. When you can see the drain impeller, you should be able to see the clogging debris. Post comments if further you have the same problem.......

Good Luck!!

Very possible that it is a fin off the impellers or could be a bushing

Hello, sounds like you either have a blockage in the pump or check valve. Remove the spray arm, the 4 screws on the filter and check for a blockage. If you find nothing inside the machine remove the panel at the bottom below the door. Behind this you will see the outlet pipe which is hooked up to the check valve. remove the outlet pipe and then unscrew the check valve from the dishwasher. has one the other day with a cherry pit stuck in the check valve. If you have any other questions please feel free to comment again. Also remember to turn off the breaker before working on your dishwasher. Thanks! Mike

Either a piece of tableware has penetrated the intake screen at the bottom under the lower spray arm, and the pump impeller is damaged, or the pump motor underneath the deck has a bad bearing and must be replaced. Remove all components including the lower spray arm down to the bottom deck. Note the position and orientation of each piece as it is removed. When you get to the bottom, there should be a pump impeller that is connected to the motor underneath the deck. Turn the impeller by hand and see if it is noisy, or moves side to side indicating a bad motor bearing.

Hi


If the water doesn't drain from your dishwasher, check these---

Drain line/air gap -- Clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.


Pump-- Dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.


Look for an impeller--It is a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.


Drain valve and/or solenoid--Dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly.

Please do rate this solution as FixYa if found helpful and revert for further assistance.

Good luck...

This has happened a few times to me as well.(VERY VERY LOUD NOISE AT THE BOTTOM)I have the same model It did stop.I did a little reading and came to the conclusion that it was the built in food disposer chopping blades were chopping up something like a cherry pit or peach pit and once an end of a wooden spoon that dropped down.If you look at your USE and care Guide on page 12 under trouble shooting "Dishwasher seems noisy"..I went through the same thing taking things apart.Its got to be it. Mine is 2 1/2 years as well. Hope this helps. [email protected]
