These rarely pop up. I don't remember the Hobart model series for the 17 series KitchenAid counterpart off the top of my head, so I hope someone can fill this in.

I have way too much going on at the moment to swing by Des Moines, but someone else should!

I saw something quite similar just everywhere from a White Castle kitchen, to a small eatery from the view going down the escalator at the Hudson's, yet-to-turn-to Macy's department store at the mall...

That machine would be the WM series.

This replaced the UM series. Based on the 15 series machines, these were very good cleaners.

A workhorse with a 4 minute cycle (I'm pretty sure). The UM series had a 3 1/2 minute cycle but they had gravity drains. These WMs were pump drain machines and had a 30 second purge between the wash and rinse cycles.

This one in particular is a low temperature model known as a "Chlorotizer".

This is a single inlet that required 120-140 degree water and injected bleach in the final rinse so the standard 180 final rinse wasn't necessary.

Noisy as all get out these were generally found behind bars as a glasswasher.

They were also used in coffee shops and "Lunch Counter" type operations.

I would grab it. In a home setting, with 140-150 water, I would think it do a very good job.

A 4 minute Hurricane.

WM-1D Hobart

Thanks, Eddie! A wealth of knowledge, as always.

I was wondering if this was closer to 15 series vs. the 17 series, judging solely by the height of the wash arm support stem, and the depth of the tank around the pump housing. Everything was screaming 16/17 series on my end.

It would be interesting to bring this machine in and 'play' with the timer, and/or change out the timer for another variety. I have a 15 series timer from a convertible Electra that would be fun.

Jeff has done a lot of customizing on one of these. The thing about these and most Hobart-design machines is that they sort of depend on successive loads to keep the temperature of the tank up so not so much heat is lost heating it up with every load.

WM 1-D hi temp!

If you look closely at the picture of the fill solenoid, you will see another valve next to the one in the picture. This makes it a Dual fill machine where incoming water of 140-160 degrees was required for the wash and the second valve was to be supplied with min. 180 degree water for the rinse. These were actually based on the 16/17 machines and originally came with the same sani-guard filters as the 16 and 17 machines.
The wash arm support was later modified from the original style which actually cut down the water pressure out of the Hydro-Sweep arm by removing the brass sealing ring/bearing and let a decent amount of water to leak by and back down into the wash impeller. The plastic filters were replaced by a stainless steel filter. But still, the water hit the top of the tank like someone was inside playing the drums.

The drain was pump assisted in that it flowed into the overflow tee below the machine and was really a gravity drain as well.If it had to pump up to a wall drain, it ran the risk of simply pumping the water back into the tank and then the machine would overflow because there was no float to stop the flow. Overflow was handled by the drain as seen in the above photos.
They were good,hard working and good cleaning machines. The really early ones had an inner door like the 15's but then the later ones came with a door like the 16/17's. Pump motors were the same as the 15-17 designs. Original machines even had a single push button on the right side but that was very quickly eliminated and replaced by a simplified design which was actuated by the door latch.
They would still make a good home machine and being a stainless tank, would last forever. And it was not until the WM5 series that there were models that retained the rinse water for the following wash. They did also produce a WMES-3 which had multiple cycles and may have saved the rinse water but it did not have an element in it either. Short lived machine and problematic.
