Hi everyone I have a KDS18 / Kitchenaid Superba that I have been using for about 1.5 years and I love it. A couple days ago though it started making this loud buzzing noise, and seems to be happening whenever there is rinsing or draining action happening. The sound seems to be coming from below, behind the kick panel somewhere, and is pretty steady although today it did not sound quite as loud. It sounds a lot like a timer alarm from an old stove - just a simple loud buzz. Everything else seems to be working fine. It seems I read somewhere about a timer below the tub behind the kick panel but I cannot find that post now. Any insights/guidance would be greatly appreciated!

Hi thank you - yes it seems to be during the entire washing/rinsing operation. I took the lower panel off today and just watched and tried to listen with an automotive stethescope. The buzzing seems to occur at all times the pump is spinning as far as I can tell by looking. Using the stethescope I was not able to hear it any louder from the solenoid. I did take off the lower support assembly, down to the impeller and took off the impeller but did not find anything down there, however, I did find some broken clear glass up against the strainers. I guess I should check again for debris. Is it possible that something has lodged into the motor as far down as below the impeller? Of course I have also wondering if it is the pump bearings, but the sound is not a whining or squealing like bearings going out, and it seemed to start so suddenly.

Just a quick update, I took it down to the impeller again, and in fact went down to the "cover - inlet" (part no c115681 on parts diagram) and found a couple piece of what appeared to be porcelain from a plate or bowl. At first I thought it was just dried soap scum but it is a glass of some type. Anyway I put it back together, started it, and in the prewash cycle it immediately made the buzzing sound again, and then a knocking sound that seemed to come from the flexible drain hose on right side of pump (as you face the pump.) I immediately stopped the cycle. I also noticed some leaking on the left side of the pump but could not tell where it was coming from exactly. This stopped when I stopped the cycle. It's never leaked before. Maybe I just didn't tighten something correctly or I put it back together incorrectly. I did notice the impeller did not spin this time when I reinstalled it, and I thought it had before because I had to hold it with a counter before.
Anyway enough for tonight, it is way past my bed time lol. I'll tear into it again tomorrow. | ||

Tear-down with pics!
Okay I finally got around to this again after taking a day off lol. Here is the tear-down, I took a pic of each step. First one is just with the wash arm and large metal strainer lifted off. Second is with the lower support arm off, next is a closer-up, next is with pump impeller off and a few pics of the wash pump impeller. Between the top retaining screw and the top of the wash pump impeller are two thin washers, then a thicker spacer. I just kept all this together. I saw no other washers or etc with the wash impeller. I took a few closeups of the impeller. For the last few pieces I am a bit unclear from my diagram manual what they are called, but my very last picture has everything I removed lined up.
One thing I noticed, and hopefully you can see it from the next-to-the-last pic, is the soft rubberish out ring, which does not appear to be in good shape. There is also some corrosion around it that I picked at a little and hopefully that is not what caused the leak. Either way I am thinking I should replace that part and use some refinishing underneath it (the marine stuff or por15 etc) but am not sure what part the rubberish ring is on the diagram. Oh I am using diagram PL-13843. I do have a kit 240366, and I notice it has a larger strainer-type blue part than I presently have. The kit does not come with any instructions but seems to have things I am missing from my machine, although it also seems to be the kit for the drain impeller, which I have not removed. Next I am going to check all the hoses for debris, but also any guidance on what parts I might need greatly appreciated. | ||

Shaft seal kit Ok, I found the kit # you referred to. The part # I referenced above is the new part number (see info below)
Part Number 4162139 (AP3102067) replaces 240366 | ||

Update
Just a quick update - I think I found the culprit in the drain solenoid valve after all. Pic attached of the piece of debris next to what is left of my retirement account for visual reference. It's metal and I think it was a clip from packaging I opened near some dirty dishes apparently. I'm guessing it was making the buzzing noise and then the rattle/knock as it worked forward to the solenoid where it lodged. All seems well for now (quiet and no leak), but I still want to sort out the seals and etc.

Thanks bigalsf and everyone for your help! Bigalsf you asked if I removed the O-ring at the top of the drain impeller and I did not. In fact I didn't mess with anything that fits onto the drain impeller shaft.
In kit 240366, at least according to the parts diagram, I have the "washer spring (impeller)," the O ring that goes on top of the drain impeller, and shims 20-23. What I actually have in my kit 240366 (see pics) seems a bit different, as it includes the coarse strainer (which I installed already), a spring washer that looks more like it would fit the drain impeller, a drain impeller with what looks like a carbon ring already attached at the bottom, and two conical washers, perhaps they are two of the shims? I actually have two 240366 kits and they both have the same parts. As a result I am quite confused as to what I need but if I am taking everything out to POR15 the corrosion, I figure I might as well replace these things too. I think I have found the larger pump gasket (d115716), but it seems I am still missing other parts including the gauges for the shims. Is there another kit that includes the gauge and other small parts? | ||
