There is no separate drain pump. KDS19's use a one directional motor. When it's ready to drain, a solenoid opens a valve and the dirty water is pumped out. Sometimes solenoids get noisy. Try spraying some WD-40 into the solenoid and all around the valve lever. Hold a paper towel under the area to collect the excess WD-40. Use compressed air, to blow the excess around and then wipe off the valve and hoses. Operate the valve by hand a few times to see if it works easier and see if that helps. All KitchenAids' with non-reversible motors have this solenoid valve, unless they are the really old ones, with gravity drain.
A little Zoom Spout Oil, used around the solenoid lever, and then operated by hand, a few times, might make it quieter, too. Use a paper towel to wipe up any excess. These drain solenoids are often noisy. If you do these things and it's still noisy and bothering you, you can try and replace it. They're probably pretty expensive. As long as it drains properly and you can stand the sound, leave it alone. A lot of ours have made this noise for years. Hope that helps. |

Thanks Brian, will try the WD-40 on the valve. Where would I get an o-ring to fit the pump housing? Thanks again -Tom |

My KDI 21's motor made a seriously raspy sound when it drained. I had only had the machine a few months and had a tech out to listen. He agreed it was a bit noisy and changed out the motor. It helped some, but basically that's just how they sound. 18 years later it sounded the same. Your machine probably just sounds that way and it's normal.

There's probably an appliance parts store somewhere in Birmingham that would have that part. If not, you can search the internet. I went through Whirlpool, several years ago, and it was quite a hassle then. I'm sure it's not getting any better. They're phasing out those parts. You have to look for after market parts, most of the time. It might come in a pump rebuild kit, though. If you get into it that far, you might as well do the whole thing, provided everything else is working properly. As you're taking it apart, watch for small washers in unexpected places. There's spring washers, a spacer, and a locking key, under the first screw, that holds the whole impeller together. When you take the gray wash impeller off, make a mental note of the number of s. washers there are, and where they go in comparison to the spacer. Then put the parts back together in the same order they came off and put a piece of scotch tape over the screw to hold it on the impeller until it's ready to go back together. You can use bowels to put things in to keep them in the right order until you're ready to reassemble. And use post-its in the bottom, to help you remember. What ever works for you. There's a blue plastic ring under the wash housing, that comes out after the wash housing screws come out. Then there's another blue plastic piece that's held in with 4 screws(sorry I can't remember the names of these pieces. My service manual is at my Mom and Dad's). Under that is a round metal piece with teeth on it(food grinder, I think)and then there's the pump out impeller. Be careful with that. It has a couple of washers on the top and a couple of washers on the bottom of it, between the pump impeller and the motor shaft seal.The one I'm working on right now has two washers, a thick one and a thin one. The thin one goes next to the seal and the thick one sets on top of it, next to the impeller. All of these washers keep the spacing right, so the impellers don't rub the housing and keep them in the best position for moving water. Then comes the motor shaft seal. It's pushed down inside the very bottom of the sump around the motor shaft, and if you don't look carefully, you might think it's part of the rubber sump lining. IF THE MACHINE IS NOT LEAKING AND YOU DON'T HAVE A NEW SHAFT SEAL, DON'T TAKE THIS OUT. The chances of getting it back in again, without it leaking, are slim. If it is leaking, you shouldn't use the machine. I consider this part one of the most important parts to replace when rebuilding a dishwasher pump. If installed correctly, it should keep the machine running well for a very long time. What I do is clean the shaft well with some 000 or 0000 steal wool and a little dish liquid and then wipe it off well. Make sure the sump is clean and dry also. Then with a little pair of needle nose pliers, reach in between the motor shaft and the rubber top of the seal and pull up on the top of the rubber all the way around, without touching the motor shaft. It must be kept smooth. If you're worried about it, wrap some layers of paper towels or a cloth around it to protect it. If that doesn't work, reach farther back into the seal and grab the metal spring on the inside and pull up. Hold down on the bottom of the rubber sump cover while doing this. You don't want it to come up too. When you get it loose, start turning it around in a circular motion, while holding the top of the motor shaft. Put a little dish soap on the shaft and when it gets to the soap it should slide right off. Then polish up the shaft well with some soap or Zoom Spout oil on the OOOO steal wool until it shines. Clean out the rubber hole where the old seal was sitting with a little dish soap and a lint free cloth. Don't use too much water when cleaning or it will run down and get on the slinger and when you turn it on it will sling soapy dirty water out under the dishwasher. The slinger protects the motor. Run you finger on the inside of the motor shaft seal seat and make sure it feels smooth and clean. Then wipe out the seat and wipe off the shaft until it's all clean. Make sure it all feels nice and smooth. No burrs at the top of the shaft or anything that's rough any where. Now put a tiny bit of Zoom Spout oil(turbine oil)on your thumb and index finger and oil the shaft, the seal seat, and the outside edge of the seal(just enough so it's slick). You can't use any oil with detergent in it. Only Zoom Spout Oil. The new seal is rubber on the outside with a spring and a carbon ring on the inside. You have to be sure to not damage the carbon ring in any way. Carefully start sliding the new seal evenly down the motor shaft. It should be tight, but slide very smoothly. After it's started down the shaft, use both hands and push evenly all the way around the seal with your finger tips. When it gets to the bottom of the sump, a slight push and it should pop into it's seat. They used to make a tool for this, but I've found this technique works pretty well. Give the shaft a turn and see how it feels. It should feel snug, but not binding. Then start reassembling you pump in the order you took it apart. If you bought a kit and you have some new parts you'd like to put in that will make a good replacement, go ahead. Clean as you go along so it will be nice when you're finished. Don't under tighten or over tighten and when you're screwing down something circular, jump across from one screw to the next. When you get to the top of the wash impeller, the spring screws should be rounded up toward you. The hole in the middle should be higher, I guess I should say. When you tighten down the top screw on the wash impeller, give the impeller a turn. You should hear no dragging anywhere. When I did my first one, I put the washers and spacers back like I found them, and I had no trouble at all. But if you buy a kit and you do have trouble, they send extra washers of different thicknesses to help fix the trouble. I'm sending you a link to a site that shows an exploded view of your pump. Bye.
