Greetings!
This is my first post here. I've been lurking for a while as a non-member and finally got around to creating an account. This site is an invaluable resource for old appliance nerds. I work for a commercial dishwasher supply/repair company, and recently we swapped out a well-worn old rolltop dishwasher for a modern machine for one of our customers. The parts situation for those machines can safely be described as "hopeless", but it's a very rare instance that I come across one, and I couldn't bear to see the scrap man take it away. So I cleaned it up enough to not reek of decades of diner dishwasher stank, and brought it home with me, custom table and all. Gonna use it as a work bench and a parts washer out in the garage, once I finish nursing it back to health. The table was the easy part; that's all cleaned up, and I sprayed the legs black for a minimum-effort finish over the three coats of paint (and rust) already on them. Unfortunately I had to chop off the control handle to pull the machine off the table, but it'll go back together with some love and adhesives when it's time. The heater is burnt out (and unavailable) and will need a clever solution. But it will rise again. It's a timer controlled high temperature machine (180-degree water supplied from an external source), 1/2hp Hobart motor. Heat on a separate circuit, though they are both 120v. Sure glad I got to spend my quality time with this one at the warehouse instead of at the account; it was filthy beyond compare when we picked it up. I have no idea how old it is, other than a couple clues: it has the newer block logo, and regulated heat. I'll finish cleaning it over the course of this week and then start piecing it back together, I think. We'll see how it goes! ian | ||

That would be a SM6T-2 I. None the less it is a SM series. That model uses a 16X16 Rack. The adult version of that machine is the LM. The LM roll tops uses a 193/4X193/4 Rack.
The SM tank was filled by pulling the Knob/Lock/Control lever toward you and held it for about a minute. That machine has a 73 second wash, 3 second Dwell, and a 12 second rinse. One small revolving Wash Arm did all the work. A separate revolving rinse arm mounted on top of the lower arm rinsed from the bottom and the upper rack got rinsed by 4 wing type stationary sprays. These were popular at Lunch Counters, Diners and Church Kitchens. Amazingly enough these were offered with electric or gas wash tank heat Your machine was in tough shape. Actually down right nasty. Nice of you to save that little guy. Attached are the Spec sheets of the SM and the Big Brother LM. stevet will be chiming in on this baby as he is the Resident Hobart Guy. | ||

I always heard these referred to at "turtle-backs." I always tried to sit near one in a diner-type restaurant. | ||

Hi Tom.
Never heard that term. Makes sense though. Insinger still makes the Ensign Model that my Dad had in his restaurant back in the 60's. insingermachine.com/insinger-pro... | ||

That Ensign is interesting, and moreso that I've never heard of Insinger before! Must be an east side thing. Most of the commercial stuff around here is single tank low temps, Jackson and American Dish and so forth. Smattering of Hobart AM's, though it seems like the AM-15 isn't all that popular, not like the near-universality of the 14.
That scan of the cut sheet is fascinating, too. Do you happen to have a scan of the back side of it also? Seems like they moved to a bigger motor (1/4 up to 1/2) and a bigger heater (600w unregulated up to 1000w regulated, Chromalox) by the time mine was built. | ||

Insinger...
Is I think only surviving because they build for the Navy. All as far as I know, Destroyers, ACCarriers, and anything Navy, they have had a contract with them for almost ever. I don't care for their designs as far as the Wash and Rinse patterns. Their machines all have stationary Wash arms and Rinse Jets. I believe Hobart coined the phrase " Either the water has to move or the Dishes". | ||

Scan of the Backside
This is the other side of the Spec Sheet for the SM.
I hope this helps.

Ian,
Here is a thread I did years ago on Hobart Dish Machines. Enjoy. www.automaticwasher.org/cgi-bin/T... | ||

It was hotter than blazes here today, but I found some time to make a bucket of detergent water (a few cups of commercial dish detergent, 30% sodium hydroxide and some phosphates) and dump the small parts in to soak. The state of this thing! But she's shiny underneath: the whole wash arm looked like the top half, and the bottom half got the soak for a few hours, no scrubbing (not that you'd wanna put your hands in that alkaline muck anyway).
Gonna let it soak til tomorrow with the other ends facing down, then spray and rinse and hit what's left with a scrubby and some delimer. She will rise again.

Eh, good enough.
All the grease is scrubbed off and it's up and running.

Thanks, WK! It needs some polish and the handle reattached but I'm pretty happy with it. :) Dunno where I'll find a heater for it though.
Naw, it wasn't out of water, though toward the end I must have covered the mic with my thumb, so it sounds muffled. It lost maybe a pint of water in the cycle (which is pretty normal, there's no real cover on the overflow pipe like an AM series has.) The customer ended up with an ADS AF-ES, I think. Not my favorite machine, but at least they don't remember to have to put soap in it! The AM-15 is really nice, but good luck convincing someone to spend an extra $6500 over an ADS or CMA low temp. | ||
