Something isnt right for food redepositing on dishes. As far as a drain loop - you certainly dont want water siphoning out but this isnt usually an issue unless your drain is under the machine or in basement. Can you raise the drain hose above the discharge point to prevent siphoning?
Also, directly under the lower spray arm is the SELF cleaning mesh filter but im wondering if the top rack spray arm is having issues? -as ive seen the feed tube to the top wash arm disintegrate. -its usually the part attached to the upper rack that will disintegrate.. Any particular location on dish placement where your seeing food bits? | ||

 My KUDI23OBO dishwasher owner's manual says to have a drain loop, but that isn't what's causing food to be on your dishes. Since my drain connection is in the floor directly in the middle/back of the cabinet I used CPVC pipe and made a loop fastened to the wall. Works like a charm. But a loop in the hose would work fine. These KA's are known for leaving yibbles on the bottoms of inverted cups and glasses because it doesn't have a constant rinse sprayer in the top of the tub anymore like the old ones did. Mine does it occasionally too. I wish I could fit a full-sized arm from the roof of an old Maytag in there...that would take care of it! | ||

TSP (trisodium phosphate) is the wrong additive for dishwashers. It generates a precipitate (basically dust particles in the water) when combining with minerals in hard water, which is not a desired effect for the dishwasher/dishware environment. STPP (sodium tripolyphosphate) is the correct additive. It is non-precipitating. | ||

Our Whirlpool PowerClean has a rinse sprayer at the top of the tub, but until I switched back to a good detergent (Bubble Bandit and Cascade fryer boil) it left yibbles on things too. Adding TSP helped, but didn’t solve the problem. Now with the STPP detergent I don’t have this issue, and I load the dishes with plenty of food chunks still on them.

Thank y'all so much! I didn't know I need STPP, not TSP. Looks like I'll have to order the stuff off the internet. If the top sprayer tube is bad, can I replace it? | ||

 Yes, you can replace the top wash arm's supply tube (the flat portion attached to the rack bottom) if that part is still available. KA used it for many years, so maybe it won't be tough to find a replacement. If the tube is cracked, that decreases the amount of water going to the spray arm, and that could be the source of the trouble.
Another suspect is the check valve underneath the machine. It's located where the drain hose connects to the pump. There's a little rubber flap inside the plastic housing that serves as the valve, and if it's stuck in the open position, not all of the water that's being pumped to the wash arms is making it there. When this valve is stuck open, while the machine is running you'll hear an "urping" sound from either the air gap on the top of the sink or if there's no air gap, from the sink drain that the dishwasher empties into.
There's a GE valve that fits if you need a new one, but I don't know the part number off hand. I tossed a lot of my KA-related notes after I got rid of all of my vintage dishwashers when I moved 18 months ago. | ||

Yes, the bottom arm should lift right off easily by grabbing the center. It's not fastened down with anything. Be sure none of the wash arm tips are blocked by the bulb-outs in the tub's side walls (for the lower rack's wheels) when you lift the assembly up and off.
Your KUDI23 has an improved Whirlpool pump and filter system compared to older (22 series and lower) KitchenAid models. It's a good choice for a vintage machine. If you don't mind the more dated look of the control panels on earlier models, the KD(C,I,P,S) 18 through 20 are considered by many to be the best that Hobart ever produced. | ||

Is this machine better than a GE Powerscrubber? I've seen a couple of them for sale. I don't mind outdated or downright ugly as long as it works. I got over "ooooh, pretty!" a long time ago. | ||

Is this machine better than a GE Powerscrubber? Well, I had a GE GSD1200 Potscrubber with the Multi-Orbit Wash Arm. I think it out-washed KitchenAids at the time in 1987. I loved my GE that I had from 1987 to 2006. I often wished I had another one. Since the KitchenAid you have is based on the Whirlpool PowerClean pump, it kicks ass too.
But my answer is also, it depends upon which model GE Potscrubbers you're seeing for sale. If you have craiglist or facebook listings, post the ads here and I can help you decide it they are the "good kind" of GE Potscrubbers. | ||

How much of the Cascade fry boiler detergent should I use per load? I just got it delivered and don't want to use too much. | ||

1tsp per grain of hardness
I have to balk at this.
My water is 25gpg.....and there's no way I would go and use 25tsp lol. Especially when most dishwashers today fill with 1gal of water or less. Your glasses would dissolve in weeks. I have to imagine a water charge variable has to be involved in that equation. When your water is over 15gpg, it's pretty much a toss-up if your dishwasher will "wash" at all. | ||

With all the chatter about not needing to rinse dishes, my dad told me the dishwasher is mainly a sinitizer, and that's why it was invented. A guy from Kowloon Alberta, or used to be, at least agrees with me. He siad rinse your dishes off. It wasn't on here, but it was in one of his online comments. | ||

The first successful dishwashing machine was invented by wealthy socialite Josephine Cochran/e in an effort to avoid the troubles of her household staff breaking her china and crystal and get the job done quicker then handwashing. Sanitization isn't stated as a primary reason for her effort, although of course a machine can douse the dishware with water hotter than is safe for hands and with more aggressive chemical cleaners.

I have no idea as to the actual hardness of my water. I found a map that said I have moderately hard water. | ||

The fill period is timed, usually 2 mins. Normal fill level is *not* controlled by the float. The float is for overfill protection ... for example in the event that the wash water doesn't fully drain, the next fill of 2 mins for rinse would overfill the tub so the float shuts the water off before that happens. Normal fill level should touch the heating element, if not slightly cover it. There is no adjustment screw for the water pressure or fill level. You may be confusing that with some models of washing machines. | ||

I've checked the water and it seems to be getting plenty of water. I'll check the spray arms next and the manifold thingee next to make sure they aren't clogged. I do appreciate all yalls help & advice. Thank you. | ||

Probably something amiss in the filtration.
Check that every thing filter-wise is seated properly, with no gaps. Also you might try this link: CLICK HERE TO GO TO SudsMaster's LINK | ||
