A dishwasher "senses" how dirty dishes are? How?

Your friend is my spirit animal.

I have tried so many ways to clean out the inside of those flat spray arms and if I get a piece of sliced almond in there it refuses to come out. Hock!

The dishwasher in this apartment is lucky to sense that the “on” button has been pushed.

I took it off the machine, and tried to back blow it with water. I also had a large pipe cleaner and cleaned the jets.

It’s a Hobart LXiH ML-130017 installed in 2007, however I can’t see anywhere where it says you don’t need detergent (as you state you don’t use rinse agent, but could). I guess we might be doing it wrong, though at least they are sanitized and do come out looking clean.

Psssss! I’m pretty sure that you’re supposed to be using detergent, de-spotting agent, and weak sanitiser for hot water machines…

Also you should be running a De-limeing cycle every month or two…. And don’t forget to take the time to clean the inside… instructions in the pdf linked to above.

In your case you can get the correct chemicals at an Acemart or other local restaurant/ bar supply place.

:grin: I do this with just one dish washer… dirty gets pre washed in sink and once the machine is less than 1/8 full; I’ll put up whatever is left in there… then refill it and run accordingly…

Commercial dishwashers usually have a built-in reservoir of detergent which you may not have been aware of.

The ones my employers used to manufacture had a space for a (5-gallon?) container at the bottom. When it ran out, it was replaced.

Slight extension / correction here if I may …

When it ran out it was should be replaced. If the employees are trained to know to do that.

When I encountered my first dishwasher about 30 years ago (before then, my family lived in old houses that didn’t have such things), I was quite surprised to learn that the very name “dishwasher” is 90% a misnomer. It would be far more accurate to call them “dishrinsers,” because unless you pre-wash the dishes, they simply don’t get clean in the machine.

That might have been true of old machines in old houses 30 years ago. It’s certainly not true of modern machines now.

Yeah, as I said above, they’re almost miraculous in how well they work. I can stick an encrusted casserole dish in my dishwasher and it comes out looking brand new, cleaner than even if I hand washed it.
