I have a three year old Hobart. I am not sure

This is a low temperature machine. So detegent and sanitizer go in together and the rinse aid goes in at the rinse cycle. At the lines in the right containers. It is pulling sanitizer at the rinse cycle?

Page 11 of the manual leads me to belive it may be priming. Do you have non return valves in the lines of all the product? Your lines should be full of chemical all the time with no air spaces.

Your detergent supplier, Hobart, Ecolab, Diversey will often help with issues like this for no charge. Don't let them play with metering though. That is an old trick to get the salemen more sales. ;>)

That's a bargain if it works. Apparently the date is hidden in the last three digits of the serial number, so February 1998 seems likely. The only sure way is to contact Hobart themselves. They have a great service department. I have used many Hobart mixers in my catering career.

I found this;

As the previous poster mentions, you can't decipher Hobart serial or ML numbers. I have about 30 pieces of Hobart equipment ranging from mixers to slicers to reach-ins to dishwashers and I couldn't make heads or tails of the numbers. Finally, I got hold of someone at Hobart who I emailed all the model numbers, serial numbers and ML numbers to and they emailed me back the month and year of manufacture. Even after I got the information, I still couldn't figure out where in the serial and ML numbers the manufacture dates were buried.

Im a tech for hobart and have seen old mixers but not that old.Hobart wont have parts but you could goto an electrical supply place,take the switch and ask them for something universal.

You can use a heavy weight gear oil or call the local hobart branch for it.To remove oil----Look under the mixer where the beater shaft is in the back and you will see a three quarter inch nut,remove this nut and drain the oil then put nut back in.To fill the unit remove the top cover screws and remove the top,you will see a long hexagon nut in length,remove this and grab a funnel then add the oil---be patient it takes time to fill as the oil is heavy.

Some of the N50's were packed with a white grease. It tends to seperate. So the oil portion finds it's way out. It sounds like it is getting into the motor case, and is running down the inside of the column. Hobart now uses a brown clay based grease --- Darina 2.

If the amounts are small, and the mixer is not excessively noisy, I wouldn't be concerned. If you wanted to fix it, the transmission would need to be removed, cleaned, and repacked. For a Hobart tech, 3 hours labor, $45 grease, plus parts.

Its a hobart correct?The data plate is on the bottom right front or on the door when opened on the left.If you dont see it then its been removed.Regardless does the display show a wash then rinse cycle?If so and it doesnt drain you either have a clogged drain hose or the drain valve is bad or stuck.If you use this just to wash glasses your model is probably a lxigc.If glasses are broken in the dishwasher which they probably are the glass has gotten into the drain body and is obstructing the valve from opening and closing.I work for hobart and services dishwashers alot.let me know.
