Does this model heat the water to sanitize
How will this stack up to my kds 18?
Are the wash times the same?

This should answer your questions.

Spec sheet for the 19 series:
These units, all models, heat the water in the tank to 150 degrees in the first rinse or pre-wash of all complete cycles, during the 2 soak periods of the Soak and Scrub cycle and also the final rinse of all complete wash and dry cycles.
Sani rinse temp is also 150 degrees. Quite a let down from the 180 degrees of the older 15 thru 18 series! But they didn't preheat the first fill!

The wash and dry cycles are key here as the Superba has a "Fast Wash" with no dry so no heating occurs in the final rinse and the wash only has a 700 watt boost during the wash period.

Thanks steve i picked it up for 25 bucks and now im kinda disappointed sani is only 150 not 180. My kdi 18 needs a timer so i will install the
19 for now. Do you know if both machine s use the same washer support arm?

18-19-20 parts

Great deal for 25 bucks. Deals like that can make for good donor machines or quick turn arounds and sales if in good shape and easily repairable.
The pumps in the 18,19 and 20 are all the same and share all the same parts including the wash arm support and washarms.
Just about all the mechanical parts are the same as well save for the timers and program switches.
For the record, the 18 was the last unit to use the solenoid activated rinse aid dispenser so it can't be used in the 19 and up to 23 series.

Cool ill post picks tommrow of my new girl
Lots of hard water buildup . I could not remove tge hydrosweep at the sellers house but it spun freely. My 18 has almost a new support if needed.i wish i could just fix the 18 but not in the budjet.
On my 18 the last finger is bent in the timer so it wont advance to reset and i have to manully
Advance it one click to get it to run again. Kinda annoying to remove all the panels to do a load each time.

The 19 series was a disappointment, not only for Hobart, but for many owners. The cycles were long with the water heating and the drying was not too great without an air heater. The other thing was that with all of the water heating, the machines aged rapidly. Owners learned to hit cancel after the last rinse and open the machine to let things flash dry in their own heat, a step back to the earlier dishwshers that popped the lid for drying. The elimination of the constant rinse was another boo-boo.

Steve can a 19 series thermostat be switched out with a older 18 series thernostat. 180 degree preheat monster would be born.

Nothing is impossible but...

First of all, if you switch the thermostats so you get 180 degrees, you will need to take both of them out if the 18 because the hi limit thermostat(87) will be set to a higher temp than in the 19. If you don't, you will have the 19 tripping the hi limit and shutting down the whole machine.

Also, you have to realize that once you go over the 150, then any protein based foods left on your dishes will likely cook right back on to the dishes and you may have some problems with washing results. But then again, you are only heating a small amount of water and it cools down as soon as it get pumped around the colder tank and dishware so maybe not such a big deal. Just be ready for longer warmup times and longer delay for the final rinse. Remember. it heats the final rinse up in all complete wash and dry cycles. You should get somewhat better drying with the dishes at 180 instead of 150.

If you want to experiment, have at it at your own risk.

Nice DW - my family had the kds19 - it worked very well. Even though a lot of people complained about the drying, if you used the jetdry it was no problem and worked perfectly!

Follow up on your Tstat question,Eric

Eric, I just looked at the parts manual and your machine has the preheat/sani thermostat on the right side of the sump. On the left side is the hi limit protector.
If you experiment with the 180 degree setup, like I said, you will need to remove the sensor assembly from the left side of the 18 with the 2 thermostats on it and install it in the 19. The wires from the old tstat on the 19 get connected to the "87" thermostat and the ones from the right hand probe in the 19 go to the "86" thermostat. You will have to make up a longer pair of wires from the right side to go to the left side. The wires on the 18 are marked 86 and 87 so you will know which tstat is which.
So just leave the old thermostat in the sump on the right side and transfer the wiring to the left side and you will get you higher temp heating and sanitizing.

And no matter what, follow what Pete mentioned. Use a rinse agent so the water drains off the dishes while drying.

Inspection time

Check and see if the cooling fan on the top of the motor is still securely fastened to the motor shaft. These had a tendency to break or crack and would not spin at the same speed as the motor itself. Also, these motors do sometimes have a weird sounding whine to them that does come and go. Since you cleaned out the tank of all its limescale and such, there may be a piece or pieces of scale large enough to be caught by the drain impeller and is making the noise.

Years ago, my Mom's machine was screaming and it turned out to be a small piece of grizzle had worked its way under the drain impeller and was making the noise.

Bad bearings will make a much worse noise but are not that hard to remove and replace. They are readily available at any bearing supply house. If you want to go ahead and do that, contact me and I can walk you thru it.
