TT vs ST (Tall Tub dishwashers vs Standard Tub dishwashers)

[washerdude]

What are your guys opinons on these 2 kinds of dishwasher tub sizes. We only had a maytag standard tub dishwasher (mdb7100aww) which works well still and it is 14 years old. Its being replaced by a kenmore tall tub in 2 days. So do you guys think about the TT dishwashers and ST dishwashers?

the big difference is in motor size

the standard tub models,  have at least  a 1/3 HP motor that is used for re circulation and draining.

 

the tall tubs  have 2 small motors 1/6 HP or less that function separately for re circulation and draining.   Less HP=less water force=much longer cycle times

Tall-Tubs

From what I gather on this forum, the Tall-Tub machines have a lot less space to deal with when it comes to sump capacity and motor size, being quite constrained "Under the skirt," so to speak.

 

Due to the lack of sump space, you can move less water.

Due to the lack of space beneath the sump (i.e. under the machine), you need a smaller pump.

Due to those two factors - you may not get dual-arm washing, and results *may* suffer from a lack of water.

And, to top it off, you probably won't get a grinder.

 

I've not seen or had the chance to use the "Tall-Tub" DishDrawer. I imagine those still work quite nicely, as would the "wide" models.

 

However - one member, our resident Bob-Loader, "Appnut," has a Kenmore TT from several years back with the disposer. Machine is frugal, has a sensor, grinder and still performs well, from what I understand.

Another big difference

You'll have to stoop down further when loading the bottom rack.  I noticed this when I switched to a Miele from an ISE Classic Supreme (KA 22 clone).

 

I'm used to it now, but in the beginning the longer reach was very noticeable.

 

Over all, the Miele does a better job than the ISE.  Apparently the components located in the smaller space below my machine are quite capable of doing as good a job or better than those on a standard tub model.

I've had three tall tub dishwashers (Maytag, LG, GE) and all were excellent cleaners. Appreciated the extra capacity, especially for large/odd-shaped items. As others mentioned, you'll notice the door nearly touches the floor when opened.

Enjoy your new Kenmore, and post a few photos if possible!

From what I understand from another post -

Tall Tub dishwashers that have a FILTER that you have to periodically clean have the smallest, least powerful motors - while the tall tub dishwashers that have a grinder/chopper/disposal have somewhat larger motors - none of which are as large as the standard tub dishwashers. But once you get used to a tall tub, and then go back and look at a ST years later, you'll feel like it's so freaking small and wonder how you were able to get by with such a small dishwasher. At least that's what happened to me when I was at someone's house with an OLD ST dishwasher and I had to check it out.

From a loading standpoint, tall-tubs are great for people who wash a lot of large or odd shaped pieces, like baking sheets and stock pots and the like. Until recently, Whirlpool and it's sister dishwashers under KitchenAid, Maytag, and Kenmore used pretty powerful motors with disposals built in and fully functioning wash arms, and while having slightly longer cycles than its standard tub predecessors, they work quite well under heavy use. However, for those like myself who wash pots, pans, and bakeware by hand to reduce wear on the dishes themselves, there's a good bit of vertical "head space" that is wasted. All the plates, bowls, cups, silverware, etc. go into the dishwasher, but because these items aren't too tall, theres a good 6-7 inches between the top of the plates on the lower rack and the upper rack's wash arm. Not that it would matter to most, but to me it doesn't seem like the machine is packed to its potential, although it technically is.

Well...

as long as I don't have reach under to install and/or repair it, give me a tall tub.
