Well a 6 month old one of these followed me home today.
The ad said, "we just want it gone", because, as I later found out, the dishwasher along with a number of other items filling the garage were the sad reminders of a failed attempt at a new career as a wine bar proprietor. "Burnered through 100k in one year", he said. The gentleman in question was going back to his old paycheck earning day job and keep the wine making as more of a hobby.

So turns out the price was EXTREMELY fair...couldn't be more so at free.
I'll clean it up and replace the power receptacle he removed when they hard wired it, and try to sell it.
Probably will take awhile but I can come way way down from msrp and it will still be well worth the effort.

MY honest opinion...

Keep it! I would give anything for one of these. With some modification you can get a resi style wash sequences. I have long considered getting one and then adapting a resi DW timer or hooking one of these up to a computer like Robert's magic Unimatic.

With the right cycle settings you can turn one of these into the ultimate Kitchenaid, and if not they are still cool to have. They clean well for normal loads after meals.

*Only thing that has stopped me is the price. The ones online just start at $1000. If you do decide to sell it you will get a really good return on investment.

If you need a project, you could easily run one of those of an Arduino and a self-made relais board.

You could probably even make one with several cycles.

Tell me more about this :) If I don't do it to a commercial machine, there is always the resi host.

Well, coding on an Arduino is simple, lots of tutorials. You would probably only use one sensor input if at all, maybe 3 for a waterlevel and door switch, though doorswitch could just be handled by cutting power to the Arduino and filling could be timed.

Use an NTC as an analog input, heating would then be represented as a while-loop in the programming (activate heater while analog input is above certain value).

All other operations would be timed, so with wait-operators.

Then you'd need some kind of input-device, a cycle selector switch or a simple start button. Preferebly run as digital input, but don't remember how many of those you have avaible.

All other operators of the machine (wash motor, drain motor, fill valve, heater, detergent dispenser, rinse aid dispenser) would be digital outputs. Each run via a relais, though you'd have to find matching ones (activating and switching current will be vastly different).

Then your program would first check which cycle is selected (determined by which digital input is closed).
The sequence would either activate or deactivate power to the digital outputs, which would trigger the relais which in turn deliver power to the parts.

The Arduino it self could be run via a USB-powersupply that's just hooked into the main powerconection, or just with a second supply.

Insinger would not be a good investment.

A Hobart WM-1 or WM-5 would be more worth your while.

Insinger is pretty much a Government tied up company. They have had a contract with the US Government for ever. Army, Navy (in particular for fitting ships and destroyers)

Although they are very well built, They lack cleaning ability that Hobart exceeds in.

Hobart always has said " Either the water has to move or the dishes).

Insinger always has had Stationary Wash arms in all their designs. They are very well constructed though.

All good points, I saw the static spray tubes/nozzles in the manual.

I've always wanted a Hobart myself.  If I ever find one near me at a good price I'll bite.

The biggest drawback of having a commercial Hobart or any other machine is hot water and utilities.

If the machine does not have a at least 150-160 water source they will not perform well due to the short cycle time. Then properly, they need 180 degrees for the final sanitizing rinse required by the NSF in a commercial application. If the machine does not have a self contained booster... then you need to find a way to get the water hot.

I am temporarily involved with a restaurant with a low temp (chemical sanitizing) machine.
The results are for the most part dreadful. It's hard to wash egg yolks off a plate with tepid water. Then there is always a "fear" factor that if the Sanitizing agent is not injected into the machine, you do not have sanitized wares.

I just find these Low Temp (Chemical Sanitizers) wretched machines that should not be allowed in any Food Service establishments. There is too much room for operator errors. Forgetting to check the Detergent, Sanitizer and Rinse Agent. The dishes for the most part are wet as there is not enough heat to flash dry the dishes.

Sorry... way off topic. Too much coffee...

Low temp machines

They make low temps machines with sump heaters where the water can be heated to ( I think up to 150, but still checking things out) so a 120 fill temp is ok. Hobart's LXEC-PR models have an adjustable main wash time which can go all the way up to 3.6 minutes.

But I do agree, I think low temp machines should not be allowed for many reasons. Its possible to never sanitize the dishware, and most models end up leaving chemical residue on everything which to me is a health risk people ought not to be gambling with.

The only plus side to low temp machines are the need for only a 120 volt supply, but in all honesty if you own a restaurant other will force beefed up electrical.

I just sold it for $750.
I had it on Craigslist at $900 and got the offer the next day or so.
I accepted as it's 100% profit for me regardless of what I sold it for.
When the guy saw it he was so happy on the condition of the machine he was beaming...I made his day, as he did mine.
It's new life will be in a Thai eatery near the local university.
