The portable Imperial 21 appears to be a true Hobart machine. That could be the reason why it kicks ass and why you like it so much. You may be able to use parts from the machine you're using now, a Superba 22, to fix whatever is wrong with the Imperial.
If that's not possible, machine #1, the white Superba 23 with "Sure Temp" would be my next choice. It's has more Whirlpool influence, but in a good way according to some of the experts here. If noise is an issue, the 23 will be quieter than the 21.
The Imperial 19 "Energy Saver IV" is all Hobart but does not offer a heated dry cycle. If you're OK with that, it should perform at least as well as the Imperial 21.
That's my $.02, but I know just enough to be dangerous. Steve T. is our resident Hobart SME so let's see what he has to say. |

If replacing the seal or whatever component is causing the leak on the Imperial 21 seems like too big a job, the Imperial 19 "Energy Saver" would be the closest match to use as a replacement machine. You may be happiest with that one.
If it's not too much trouble, you can test out the other machines outdoors or in a garage by filling them with water, either from a bucket or garden hose, and if necessary, using a bucket to catch the water as its pumped out during the drain function.
The first test is the easiest and requires no water. Just give the wash arm a spin and see how it behaves. If it spins freely and quietly, great. If it chatters its way around, you're looking at worn components.
A deciding factor for you may be the number of rinses. The Superba "Sure Temp" only provides a single rinse after the main wash. I've owned a couple of single rinse models and it has never been a major issue. Your current dishwasher is a single rinse model. The Imperial 19 (and I think the 21) provides two rinses after the main wash.
If you're dealing with hard water, you may want to take into consideration which machines have rinse aid dispensers and which (if any) do not.

I don't know if the wash arms are interchangeable on the two Imperials (there's an outside chance since the 21 is a Hobart), but you can determine that with just a visual check. If the hubs look the same, try taking the arm from the 21 and putting it on the 19 and see if the chattering still happens -- that's if you first determine the arm on the 21 doesn't chatter where it is now.
The arms lift right off. Just be sure the tips of them clear the bumps on the sides of the tubs that support the lower racks, and lift straight up.
If you still have chattering on the 19, the wash arm support likely needs some new components which others here can elaborate on. |

Hi again. Yes I was referring to the white "top of line" model. IIRC it has the porcelain tub and racking just like the Hobart design. I have heard the Whirlpool pump & motor was a fine combination with this design. I think it is a pretty machine.
My Classic 21 Superba KDSC21A 223328700 was purchased by it's original owners in 5/1986. I bought it in 2007 for $40. The only reason it was removed from it's home was the owners were selling the house and they thought a brand new dishwasher would help sell the house (LOL) The normal cycle sequence is wash - purge - rinse - wash - purge - rinse - dry These machines used 2gal per fill (not sure how much the purge uses; the water runs for maybe 15-20 sec). It does a wonderful job. Whirlpool bought KA in 1986. Hobart was using a motor from Emerson at the time. |

It could be that a plastic/neoprene washer belongs there. If all three of those machines have interchangeable wash arm and support components, you should be able use the best ones to get at least one machine working properly.
This is where things get sketchy for me and I'll have to turn it over to the experts for further coaching.
If Steve T doesn't check in here soon, try to e-mail him directly. |

Thank you for getting back to me. Just wanted to make sure you didn't think I was the dumb-bunny that I sounded like from that first response I gave you. It's my bedtime now, but will continue tomorrow. Christine. |

The white Superba has only one rinse after the main wash.
Reversing motors appeared beginning with the 21 series, as did the single final rinse. The Imperial 19 has a non-reversing motor. You can hear the distinct snapping sound of a solenoid when machines with non-reversing motors go into drain mode.
There's definitely something amiss with your current machine if it can't clean a load like the one pictured in reply #20. That should be a cinch for a properly functioning KitchenAid.
I think you'd be satisfied with the results from the white Superba if that turns out to be the easiest option for replacing your current machine. If you decide to go that route, there is a check valve you should examine for proper operation. It's located at the end of the drain hose under the machine where it comes off the pump, and is fairly easy to remove. It's just a rubber flap inside a plastic housing, but it's important that it's not stuck in the open position, otherwise spray from the upper wash arm could be compromised.

I didn't post the picture of the Superba Classic 21, but am thinking it would be missing one or two of the buttons that the white Superba has. I don't think I've seen the "Quick/Glass" option on machines older than the 23 series.
The "garburetor" wouldn't be a new feature. It's just a way of capturing and pulverizing solid food waste before sending it down the drain when the machine empties. KA's made before the white Superba had this capability, but on the white machine the pump is a new and improved "power module" type that (some experts will say) performs better than its predecessors. A visual check of the white Superba's sump area shows the obvious difference from your other, older KA machines.
I did have a leak issue with my In-Sink-Erator Classic Supreme dishwasher (identical to the KA 22 series you're currently using) after I installed it. I couldn't find the source down below and I don't remember how I finally isolated it, but it turned out to be a loose screw on the exterior that helped secure the glide for the top rack assembly. An easy fix.
I hope yours is something as simple to repair. If not, install the white Superba which should give you good results, and then you can take your time trying to fix the Imperial 21. |

If you have access to the "Shoppers Square" forum, that's where to post. If you don't, you can post it in the forum appropriate for the age and/or type of the item.
Copy the URL off the page you want to provide a link to, and paste it in the "URL Link to share" field directly below the "Message" field where you type the verbiage for your post.
Then hit "Preview," then "POST this to Discuss-o-Mat"
Good idea to give the white Superba a whirl before installing it. If you do decide to use it, run the machine empty of dishes with a cup or two of white vinegar added after it fills for the main wash, or you can buy Lemishine powder at the grocery store or Target, which can also be used for cleaning the machine (more convenient than vinegar since you can use the dispenser) as well as for glassware loads. It's usually found on the same shelves with the dishwasher detergents. |

Yes, I've read here and other places about that vinegar idea. But once it's all rigged up for it's test-drive, what is it I should look/listen for? |

Before you start the machine, check the filter assembly under the bottom wash arm and make sure it's clean. Examine the wash arms and check for any clogged holes.
After you start the machine, just listen for the sound of wash action -- there should be a bit of a rhythmic sound of water jets spraying the sides of the tub. If you want to be sure both wash arms are rotating, after washing starts open the door and check the position of both upper and lower arms. Close the door, re-start and run for about 10 seconds, then open the door and check the arms again. They should be in different positions.
Do this with racks in place. The upper arm is incorporated into the upper rack, and the lower rack has tabs up front on each corner to deflect strong spray jets that could otherwise force water past the door gasket.
Let the machine run until it drains, so you can be sure that function is working as well.
Check all around the machine for leaks while it's running and during the drain process.
If it passes this inspection, one part of the cleaning process is to wipe out the lip at the bottom of the door. With door open flat, feel down in the area between the door and tub. It'll probably have some gooey crud built up in there. |
