The results.

I would challenge any vintage or modern dishwasher to produce these results in 62 seconds.

What year?

Cool machine, is it installed in your home??

WOW

That machine is just Gorgeous and Pristine Shape for it's age. Even the lettering around the Temperature Gauges.

They are Fantastic Cleaners.

Beautiful machine!

Does it have the revolving wash & rinse arms above the dishes also?

Cool Old Hobart DW

I would challenge any modern DW to produce these results in 62 seconds.

 

Nick I sure you are going to win this one on time but you didn't show us the before  picture of the dishes.

Revolving Wash Arms

Yes there is an Upper Arm with Double Jets on the end but only 2 more jets on the Upper.

The Upper Rinse System is a Curved Pipe with 4 Stationary Fixed Spray Nozzles. The Later Machines switched to a Revolving Upper Rinse Arm.

Because the Wash Water is recirculated it's best to Spray the Rack off before sliding it in. But I can tell you, if you don't Pre Rinse the rack, the results are spotless.

Spraying off dishes

I agree it is important to spray off the dishes in this type of machine. I do this very thouroughly. If you look in the scrap trays you will see the machine is still clean and I had done about 40 racks since the last water change.

Is this machine installed in your home

No but I wish it was.  It is in the Prior Lake Mn.  VFW.  It has been there for over 40 years.

Hey Nick

Being that machine is in a VFW, it will probably last 100 more years. What is the usage on that machine ? Just Functions ???

Grandpa Hobie

Gets used for: Monday burger nite, Taco Tuesdays, Wednesday bar menu, Thursday Chix strip nite, Friday full menu(I run him for this), Steak fry(many of which I work the broiler)every 2nd and 4th Sat. of the month, 8 Pancake breakfasts a year, and many catered functions. This DW is still a daily driver. After 42 years he's only on his 3'rd motor, 4th set of heater coils, 2nd booster heater and original everything else.
I would bet this dishwasher has done millions of racks over his life. He just passed an inspection from the Minnesota Department of Health so he will do thousands more.
I doubt many dishwashers (commercial or domestic) could carry on the legacy that ths one has and clean as well with as few repairs.
LONG LIVE VINTAGE HOBARTS!

You are correct about the upper wash/rinse system in this machine. The Ni-resist wash arms continued through the AM-ll series before being replaced with the Ball Bearing hub SS arms of the AM-12 and 14. All single rack door type machines up through the AM-12 used some varient the 4 nozzle rinse system. The revolving full size upper rinse arm did not appear on Hobart door type dishwashers until the AM-14 was introduced in 1983.

Fact Check

Just a quick update on the revolving upper rinse arm on the AM Series. Since I am actually in the office today, I went back into the old manuals to check on the rinse arms.
The AM12 actually had both styles of arms. Initial production had the stationary piping with 4 nozzles in the piping parallel to the doors kind of like one in each corner and a single nozzle in the center of the hub casting for the wash arm. That was replaced with the revolving arm style we have become used to since that time. This would go back to the late 70's early 80's.
