I still miss my old 90's era dishwasher. I ran the numbers that thing was more effeceint end to end than modern ones. Because you didn't need to prerinse dishes. Prerinsing with warm water completely wipes out the modern ones energy and water savings.

As for machines with plastic parts, there should be a standard that machines need to last ten years. And if one shows up at the dump before then the manufacturer has to buy it back from dump for the prorated list price.

Modern dishwashers don't need prerinsing and aren't tested with prerinsing, you're just using it wrong.

"You're just holding it wrong"

It's (potentially mandated) poor design if it's so easy to misuse.

The point is the old lamented machine you couldn't not do it right. Pan encrusted with 3 day old spaghetti sauce? Toss it in and it came out clean. Roommate burned rice in a pot? toss that in after. Comes out clean. Wife's pot and dish with dried mac and cheeze? Yeah also come clean.

And yeah if it was just a light wash you could set it to 'low'

Also that machine I installed in 1995 and it finally died in 2006. Friends buy expensive European machines and invariably some plastic part dies after 6-8 years. Low end machines are worse.

> On two occasions I have been asked, — "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" In one case a member of the Upper, and in the other a member of the Lower, House put this question. I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

How can a dishwasher possibly be designed to discourage people from doing things to the dishes before they put them into the dishwasher?

I have not pre-rinsed for a dishwasher ever. Have had Two in the last 15 years, current one is less than 5 years old and made by Siemens. They’ve always worked fine.

Have you cleaned your dishwasher's filters? Manufacturers tend not to recommend 'prerinsing' and many actively discourage it. Most dishwasher performance problems are down to the filters.
