US made DW : how do these work ?

The food grinders/disposers work during recirculation (washes/rinses).
One of the reasons I bought my LG dishwasher is that is extremely quiet, yet still has a food disposer. I don't always scrape dishes very thoroughly, so I'd be cleaning a manual filter constantly.

Which model do you have? I'm looking at getting an LG Dishwasher this weekend, but I don't believe they all have disposer, and I want one that does.

I have a discontinued model; 9810. It was their TOL model when I purchased it.
The current TOL model is 9932. I believe the new model doesn't have a soak cycle, but it does have steam and a third rack at the top for silverware (although the machine comes with a generous, standard flatware basket for the bottom rack.)
LG's TOL machine scored near the top at Consumer Reports, but lower end models didn't fare as well. LG's dishwashers are also reported to be prone to needing service. I've had mine about 1-1/2 years, and so far no trouble with very heavy use.
Others who frequent this site have already had breakdowns with their relatively new LG's, so buyer beware.
Having said that, this is an awesome dishwasher. Capacity is enormous, loading is very flexible, the steam option strips pots/pans of gunk and it's very quiet and water/energy efficient. Having had KitchenAids, Frigidaires, a Maytag and a Whirlpool, this is the best-performing of the lot. My main concern is with reliability.

I believe that all KitchenAid DW have the food disposer. Bosch DW do NOT have them. So Bosch owners here generally scrape the plates/dishes before washing them, though pre-rinsing is not necessary, even if the dishes have dried pesto, marinara, bolognese, alfredo, al'arabiatta, or polpetti on them!! (I didn't cover every pasta sauce but I covered some of them).
Who is Alfredo ? 
Jim,
as i have never heard about a "pasta all' alfredo" I googled it and discovered that's a 100% american fake italian recipe
I ran into this blog owned by an italian woman livin' in CA
She says it would be easier to convince Californians that the Pope is a woman rather than pasta all' Alfredo doesn't exist in Italy
PS aRRaBBiata is the right spelling. Anyway in Rome you'll hear "arrabbbbbbbiata" and in Bologna "aarraabbiaaaaaaataa"
apart of Al, guess your DW with grinder have filters to avoid nozzles clogging. How often do you clean these ones ?

Pasta Alfredo
Qui lo dico e qui lo ripeto e pure a viva voce: LA PASTA ALFREDO IN ITALIA NON ESISTE!!!! Ogni italiano negli States prima o poi verrà a con...
I don't think it is so much a fake Italian recipe as much as it is a dish created by a chef in an American restaurant. There was a column in the New Yorker magazine in the mid 70s about what was in and what was out of fashion and I remember that one of the things that was "out" was Pasta Alfredo at Alfredo's (restaurant).

Personally I HATE fetuccini alfredo but I did add it to the list in the mistaken belief it was authentic Italian.
I grow my own basil and make pesto with it. Mangia beni!!
(No I do not have a reproduction of Michaelangelo's "Last Supper" in a gold frame on the dining room wall....growing up in the 1960s, nothing said "ITALIAN-AMERICAN" more than the Last Supper in a gold frame hung on the dining room wall...besides, I'm 100% German-American).
To answer your question: there is a removable filter in the bottom surface of the tub in the Bosch. You simply unscrew it counter-clockwise and it lifts out for rinsing. I inspect it regularly, but only four or five times in eight years did I actually find any material in it. Put it back in place and rotate clockwise and it locks into place.

sorry Jim, my question was made in a ambiguous way.
I wasn't referring to your own Bosch, but was wondering if those american made dishwasher with a grinding disposer even have a filter to prevent nozzles clogging.
I suppose this filter is self cleaning, otherwise one'd prefer scrapin' plates rather than cleaning this filter after each cycle. Are there some nozzles just to keep it clean ?
BTW Leonardo da Vinci painted the Last Supper. It's close to me, in Milan :

An interesting thread
I clearly remember the Sears and otherD&M machines that had the macerator blade located in the pump which would grind up food particles and such, though glass and cherry/olive pits usually jammed the motor! And I clearly remember what alr2093 mentions about the wash arm nozzles getting clogged up in these units. It wasn't just the top arm as the bottom ones would clog too.
I would say that the primary reason for this was that there was no filtering system in the machine to catch the larger debris and the upper arms were supplied with water that was pumped by the actual drain impeller which sat below the macerator blade so all that chopped up stuff went right back up into the machine.
Kitchenaids always had the fine and coarse flters but didnt have any type of grinder of sorts until the 18 series which had a stationary plate which would grind up particles as the unit drained the water out of the tank. And it would grind whatever got past the two other filters. The drain impeller was just that, it was only used to drain the water and not used in pumping water back on to the dishes.
When the 21 series came out it had the "disposer" drain impeller as well as the reversing motor in it. It would take the water and use the drain impeller to circulate water into the soil chamber that was part of the wash arm support and the water was forced thru that very fine mesh filter and back into the washtank to be circulated over the dishes. Once again this was after the water passed thru the fine and coarse filters. The motor would then reverse and the impeller would drain out the tank. While doing this the small nozzles under the wash arm would flush any debris out of that chamber and down the drain. Seemed to be winning design as nearly every other manufacturer adapted the same concept in one form or another. This system was used on the 21 and 22 series. The 23 series went over to the Whirlpool designed Power Module pump with a larger soil chamber and basically performed the same function. It would be up to all the other members to decide if the K/A system was better or not. What say ye?
I too have a Bosch older model from the 90's with the removeable screens as well as an Electrolux with the screen setup without grinders of any sort and they both seem to do an excellent job with very little debris left to remove that is truly food. Harder items, of course are trapped and eaisly removed. Much of that I am sure is due to the formulation of today's detergents with the emzymes that eat up the food so I suppose it comes down to personal preference.
One last thing, is that I would not compare the grinding blades in the current tall tub Whirlkenkittags to what they used to produce or even their Power Modules. There is no way they do as good a job and they leave some serious residue in the tanks, in the pumps themselves and sometimes on the dishware. But again, that is just my opinion.

thanks Steve.
So the disposer system works better in those "old school"/"niagara-falls-like" DW because of higher pressue and more water
I'm curious about commercial DW too. Here in europe the tank system commercial DW -even Hobart ones- haven't any grinder.
Does any commercial DW in the US have an internal disposer ?

commercial dishwashers
As far as I know, there are no commercial dishwashers that utilize any kind of grinding apparatus, though for what some users throw into the machines, they could use one!
All the undercounter machines from all manufacturers, use a series of filters which will trap large objects and again, as far as I know, only the Hobart WM5 and SR24 series have the small metal drain top which would aid in breaking up small particles as the water is pumped out of the machine. These machines use the same pumping system as the 18-20 series Kitchenaids used.
The WM 5 is obsolete and no longer made and the SR24 series replaced it and is still currently produced.
Larger, free standing machines use strainer pans and scrap buckets to catch the large debris and have a separate final rinse section of the machine or portion of the wash/ rinse cycle to rinse away any debris left on the dishware as well as sanitize it chemically or with hi temp rinse water.
Hope this helps.

The Maytag JetClean of yore had a three stage self-cleaning filter as well as a stainless steal grinder. You could put corn meal in the DW and not have it redeposit on the dishes.
