Sound insulation

As far as I know, there wasn't much sound insulation on any KA until after WP bought them. Shortly thereafter (1987-88?) the WhisperQuiet system came out on Superba models which involved sound absorbing pads cemented to the top and sides of the tank and the inner door, thick fiberglass batts behind the toekick and motor panels, and a fiberglass blanket over the tank. The sales literature of the time also chatted about a redesigned wash impeller and the pump being isolated by a rubber ring, but I believe the pump had been isolated by a rubber ring since the KD-18 series. I don't believe any model other than Superba got much sound insulation at all (other than a thin fiberglass blanket) until the WP-based 24 series.

I remember that when we got our Superba Monterey KUDS21MS0 (note post-WP acquisition model number) in 1988 we were thrilled at how quiet it was--we no longer had to leave the room to have a conversation or talk on the phone. My parents still have it, and I think it would be considered somewhat noisy by today's standards.

Which Kitchen Aid?

Nice toy! Enjoy

Hey I LIKE those frigiluxes.. besides the huge waste of time (to get a cycle done).. LOL

Is this KA the one where to motor runs constantly and the fill and drain solenoids open and close..or is this a later one where the motor reverses to pump out used water?

 

[appnut]

Steve, this is one with the reversing motor.

 

[toggleswitch]

HOBART did the reversing motor?

I would have sworn that was a Whirly gig.

I can't believe WP dropped the fan-forced dry (later on, in general) Even if it ran for 3 minutes to purge the steam then went silent I'd be happy.

 

[appnut]

Yup, I have some friends from church who have this dishwasher of subject. Their house was built in 1983. A few years ago they were having some wash performance probs with it and I helped solve the issues to tell the repairman. And I particularly told this to keep the machine because it was made by Hobart, a tank. I've been there many times--yup it's noisy. But it pauses between wash & drain, no solenoid. Some other friends had a KDS19. That one still had the drain solenoid. And it did run all the time, except when it stopped to heat the water, which was very major event in the cycle.

Good Choice

I knew that with your fine collection you would replace the dishwasher with something of substance. Very nice machine. Michael

 

[westytoploader]

Wow Greg, that's a solid-looking DW!! I didn't realize KitchenAids had reversing motors either...thought that Whirlpool was the only one! I'd love to find one of these in a portable version!

Congratulations!

 

[gregm]

thanks all

yes, it does have a reversing motor, I will say one more time, it is the NOISIEST dishwasher I have EVER run or owned, but I love it !!!

reversing motors

Hi Austin!

Nice to "meet" you!

D&M dishwashers had reversing motors, too!
Sears, Caloric, Amana, Magic Chef were all D&Ms going back.

If it were not for the "Hobart" name on the nameplate, I would have sworn that WP had taken over this KA and imposed their reversing motor on it therby revising its engineering.

Or did they finally wise-up (at the end)and add filtation to recirculated water?

 

[appnut]

Steve, KA DWs did have a filter, a really good one that was quite big, underneath the hydro-sweep arm. Ya had to remove the wash arm and remove the filter to clean it. WP didn't put their power-clean module into KA dishwashers until the 23 series I believe.

 

[deeptub]

On at least the 15 through 20 series, KA claimed the filters to be self-cleaning "under normal circumstances". The inlet to the drain impeller on all of them is below the fine screen. On the 15-17 models, the any soil on the screen theoretically gets washed down with the downward movement of the draining water. On my KDS17A, I find the screen needs only occasional cleaning (every 6 mos or so), and at that point the screen is by no means clogged. On the 18-20 series, there was a single small jet on the underside of the lower wash arm that would "hose down" the screen and flush particles down toward the drain inlet. On this pump, the drain impeller was also a soft waste disposer. I've never cleaned the filter on my KDS-18 (though I continue to check it). The pump on the 21-22 series (which actually first appeared on the 20A series) had a reversing motor. While in wash mode, the drain impeller (which is also a hard food disposer) becomes part of a "bypass filter" system--it pumps water up from the drain inlet through a microfine filter at the top of the pump housing--water actually comes OUT of the microfilter in the pump top. The wash arm has a large hub with 12 or so needle jets which continuously backwash that micro filter, while a small jet out on one of the arms "hoses down" the main filter.

The micro filter on the 22 series is much much finer than that on the 20A-21 series, and can be retrofitted (its the only part they sell for all 20A-22 series).

Of course cycle sequences vary depending on the model, but after most wash segments finish draining (all wash segments, in the case of gregm's imperial), the machine fills with a small amount of water and briefly runs in "wash" mode to purge the micro filter's "soil collection chamber", then drains. Sometimes you can hear the drain impeller grinding something during this process.

Because of this micro filter, all cycles have only one rinse after the main wash, and that seems to be fine.

Many diesel engines filter their oil on the same bypass principle--diverting a portion of the oil through a much finer filter and back to the oil pan (to filter out soot) while the oil going to lubrication points goes through a regular oil filter at maximum pressure.

I think the WP/KM/KA dishwashers today (except the BOL WPs with the "sewer grate" filtration and "hit-or-miss" wash action) use a similar type of system, with a microfilter in the top of the pump and a large wash arm hub with backwash jets.

WHew, sorry this was so chatty.

T.

PS: the link is to the microfilter pump top of the 20A-22 machines. Gregm--lift off the bottom wash arm and check yours. I've come across many 21-series models with torn microfilters. It would be a great excuse to upgrade to the finer filter.

Kitchenaid KDP-18 Patrician when made & parts available?

Wow this site is cooool!
I have an old Hobart/KA KDP-18 "Patrician" dishwasher s/n 201055303 and I wanted to know how old it was.

It still runs but makes a god awful sound when taking on water. I'm thinking its maybe the inlet valve?? Any ideas? Also, cleaning quality has gone down so Hubby wants to trash the old girl and I'm trying to save her. I'm fairly handy but work as a tile setter, thanks! Colleen

 

[gregm]

fill valve noise

You could take the fill valve apart and remove and/or clean any debris ....... for what it is worth mine when filling is rather noisey (whistling sound) too. I also have a WP made "In-Sink-Erator" DW EXACTLY like this one and everything is literally identical .......... except for some very few subtle differences.

 

[Geometrictile]

Gregm, mine sounds like it's gonna explode when it takes on water!! The pipes vibrate something fierce and I'm afraid it's going to blow. I have an old house (1896) and would hate to have a pipe burst because of this old dishwasher. But I'dd love to fix it and keep it going.

What year do you think this KDP-18 is and where could I get a fill valve if cleaning it out doesn't do the trick??

Thanks so much!!! Colleen

 

[fixerman]

Call or go to Sundberg Appliance parts. 964 Rice St. Saint Paul.
Tel 651-489-8004. The PN is A116152 but there is a replacement number. Sundberg can help you with the new part no. It is a redundant valve meaning it has 2 solenoids on it. I think the replacement has only one. Call me and I can get the valve at cost. I think the retail is about 40.00. 763-788-0778

 

[mrcleanjeans]

and now, let us SPRAY

the KD-18 series introduced the upper level power wash which was suprisingly short,not extending fully to the ends.In 1980,KA introduced this wider arm with the angled jets for the upper rack corners,and also announced you could now turn your water heater down to 120 degrees.

 

[frigilux]

Congrats on your new vintage find, gregm! I was fortunate enough to have a Hobart-built KA for a few years---around '84, as I recall. When I moved to a different town, I purchased a new KA and by that time they must have been Whirlpool-built, because the water heating prior to the first wash was gone....

I am a proponent of Frigilux appliances, but having said that, anything less than their TOL dishwashers SUCK. I don't know why, but it's true. I don't blame you for wanting to be rid of that plastic piece-of-crap!

 

[appnut]

David, the 18 series didn't last all that long. The new 19 series that allowed you to turn you water heater down to 120 degrees came out in 1980. I THINK this was called the Energy Saver IV. Had friends that had the Superba of this 19 series. What really bugged me was on some cycles it would fill/spray at the same time and once the water filling time was complete, the pump turned off and it sat until the water was heated to 140 degrees. I heard a couple of people tell me they didn't have very clean dishes because of that sequence. The debrib kinda baked on. The 19 series Superbas would take forever to run a cycle because each major "event" in a cycle had the water heated and a couple of the "rinses" just had tap temp fills. And this mahcine dind't have a heat/no heat dry option, it was no heat always. This was a short lived series. I believe the next series had the reversing motor which filled first without circulating and heated before it circulated. Someone graciously correct me if I"ve got some a bit out of "sequence".

 

[DADoES]

As you know, my Superba has the 'idle water heat' periods. It's either a 22 or 23, LOL, I don't even remember which. Didn't have any specific trouble with debris getting baked on, but I have to agree that it'd be better if circulation continued during heating.

kitchenaid kds19 series

My mother had the 19 series that lasted her until last year. It actually came out in 1979. Now she has a GE tall tub like mine. In the 19 series the water heated in the 1st and last rinse to 150 degrees with 1400 watt heater going and the cycle was completly still no pump action while heating. In the main wash the water was heated by 700 watts to maintain the tempature, but the cycle was actually in progress. The cycle was relativly long compared to the 18 series kitchenaid. Drying was always no heat. You realy needed to use jet dry to have completly dry dishes. The machine was a very good cleaner but noisy. The 20 series looked almost identical that came out in 1981 put back the drying heater.
