To Rinse or Not Rinse - Dishwasher Story

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

It depends...

On the dishwasher. Machines without 1) good water distribution, 2) ample water use, 3) a long hot main wash, 4) a self cleaning fine filter, 5) maceration, and 6) ability to process reasonable quantities of food particles and flush them away; will always require various levels of pre-rinsing. There is no way around it.

 

 

There are only a handful of dishwashers that ever satisfactorily met all 6 of these categories. The Whirlpool Power Clean filter modules, Whirlpool built Kitchen-Aids, MOL/TOL Maytag Jet Clean dishwashers, *GE GSD1200-GSD2800 series dishwashers between 1984 and 1994, GE Profile model Z GSD4900Z-GSD3400Z, were the only dishwashers ever produced where dishware could be loaded without any pre-rinsing.  Whirlpool's point Voyager system could also fit these categories provided soil levels never went above moderate. 

 

*The 1984-1994 GSD1200-2800 series had an Achilles heel where the steal macerator would break off with time or a hard object like an olive pit went into the sump. GE specifically designed for such contingencies in that 1984-1994 sump boots had a dammed "pocket" to the left where an unpulverizable hard object would be kicked into the side holding dam and remain there until retrieved. Unfortunately the idea did not work out so well in that the pit would cause the steel macerator to break off in the process.

That leaves the majority of dishwashers past and present requiring various levels of pre-rinsing which defeats more than half the purpose of having a dishwasher. People just don't know any better to say or realize otherwise. People never saw the limitations of tall tubs when they arrived because they were pre-rinsing already, and many of those with Power Cleans and Jet Cleans were already conditioned to pre-rinsing. The few that made the switch from no pre-rinsing to tall tubs saw the light, grumbled about it, but when they found that tall tubs were the only machine available on the market they had no choice but to alter their habits while the rest of the world routinely gaslights their lived experiences.  

 

To live in modern humanity is to have both your sanity and intelligence invalidated. 

 

If everyone was like me the Whirlpool Power Clean Module with ample water use, time and heat would make up 95% of all residential dishwashers including those in apartments, condominiums and rental properties.

 

 
 
bosch

Chetlaham, my Bosch which is under the Kenmore fits all 6 requirements, with 7 being that it doesn't melt plastics when drying. Food and grease have nowhere to hide, especially with Finish products I use. I can tell you that mine cleans equal to the whirlpool power clean module. Water is constantly moving while the pump is running at all pressure levels.It can soak and/or blast the dishes. It does both at certain parts of the cycle. When I opened mine, I received a face full of water. If everyone were like me, I'd either update the dishwasher to a Bosch or Whirlpool power clean platform, even under the Kenmore label. I'd highly recommend use high quality detergents such as Electrasol (now Finish) and jet dry (now Finish jet dry). I found they work better than Cascade, especially after the experience of the dishwasher choking on suds. I'm running my second load of dishes for 2025 and the performance is night and day with Finish products compared to Cascade.[this post was last edited: 1/7/2025-10:52]
 
cascade against finish

Cascade and Finish claim you don't have to pre-rinse. While that may be true, I quit using all Cascade products due to excessive suds, causing my pump to choke and labor unlike Finish. Finish, on the other hand, just works so much better than any Cascade product. Finish Ultimate is my go to for the best results, and so does Finish jet dry which is a lot better than Cascade power dry circles around. My dishwasher is running right now.
 
pre-rinsing

If I have to pre-rinse and use a store brand of detergent that's the cheapest, I'll pass. I agree with norgeway. I. NEVER!!!! Pre-rinse anything. What's the purpose of having a dishwasher if I have to anyway? It wastes water, shortens cycle, and ends missing the food spots, let alone diminishes cleaning quality to the point where today's detergents eat away at the racks. I'm in the no pre-rinse camp. I've said it before, and I'll say it again until I turn blue in the face. I don't understand why people think dishwashers need to be babied. I've seen dishwasher racks fall apart because pre-washing dishes before the dishwasher, which contributes to detergent eating away at the parts. This could eventually damage the pumps. You are causing corrosion to occur if you don't have food stuck to the dishes, along with using a good detergent and rinse aid like Cascade or Finish. Like appnut, I get brilliant results from Finish in my Bosch built Kenmore.
Stop pre-washing your dishes before you put them in the dishwasher! You WILL ruin your racks! Quit![this post was last edited: 1/8/2025-18:20]
 
I dont care what you do with your dishwasher or use in and I will continue to pre
-rinse, use the cheapest detergent and pack my dishwasher full before operating and my method has worked fine for me, clean dishes and a dishwasher that still runs perfect after 31 years and for those who dont like it, I dont care.
 
My take

Pre-rinsing is done 50/50 in my current household. I have a Frigidaire Gallery dishwasher, model # FGID2466QF4A; it came with the house and has features such as an OrbitClean spray arm and Sahara Dry. This dishwasher works well for the most part; however there are certain dishes that won't come out fully clean: bowls in the bottom rack (particularly those with chili and hard, stuck-on food), overly oily items (like pots and pans), wooden spoons with stuck-on pasta bits (in the top rack) and forks with food trapped in between the tines. Plates, pasta bowls, knives and spoons on the other hand, DO get fully clean, along with just about everything in the top rack. And yes, I do use Finish Jet-Dry as my rinse aid.

I use Finish Powerball Quantum tabs; I was previously using the more basic Powerball tabs, but then upgraded in hopes of improving performance. Despite the company's claims that pre-rinsing is not necessary, the detergent still won't fully clean the aformentioned dishes, leaving hard food spots and oily residue on them. Even when I step up to the more heavy-duty wash settings, such as setting the wash pressure from "surge" to "scour," and the temperature from "heat" to "hi-temp," the dishwasher's performance is not any better.

As a result of its inadequate wash performance, I've developed trust issues with this Frigidaire; nowadays I just want to pre-rinse EVERYTHING before running the machine. As a matter of fact, my mom does the exact same thing, as she doesn't trust the GE dishwasher at her apartment. Even prior to my parents' divorce, she pre-rinsed everything before loading it into the Kenmore (GE) dishwasher at my old house.
 
It comes down to design, water hardness, and detergent.

I can go crazy with my modified KDS-18, a tiny bit less with the Powerclean Kenmore.

Less so with the Maytag reverse rack.

Even less with the Point Voyager, especially the top rack. The top rack has weak performance but the jet design/configuration is ridiculous. There's a really bad dead spot in the center of the rack which becomes obvious by looking at the wash arm. The engineer who configured those wash arm jets should be fired. Does anybody actually test their designs anymore before kicking it out to the public?
 
“Does anybody actually test their designs anymore before kicking it out to the public?”

Unfortunately, companies no longer care to work out the bugs since they let oblivious consumers, stupid over the top regulations (the feds get ever more drunk with their overreach), bean counters (to hell with bean counters) who don’t know anything.

Consumers really are anti-customer, make it difficult for us who want quality and such.

It always amazes me what was able to be done many years ago, but now it’s near next to impossible.
 
Putting to the side the fact that a certain individual obviously retrieved this ancient thread (seems to be a trend with said individual), I actually have first-hand experience that how much pre-rinsing you have to do definitely depends on external factors.

I had to pre-rinse everything in my old Frigidaire machine. I'm talking there couldn't be much more than a light smattering of soil on a plate or it wouldn't come clean. I tried everything, different detergents, rinse aids, etc. Then the door latch on the machine broke so that it ran while open. I knew it wasn't supposed to do that, but I took advantage of the problem to observe what was happening to create such miserable results. There was very little spray going on, I think one or both of the wash arms was broken, and also my soap pods weren't breaking open every time to release detergent. Mineral buildup had just gotten to a point where everything was rusted, clogged, and just gross.

I now have a new dishwasher, a GE/Haire/some Chinese-built contraption, but it doesn't much matter because boy howdie this thing runs circles around the old Frigidaire, even back when it worked properly. I've put everything from plates that had lasagna served on them to filthy baking dishes in this thing and they've come out perfectly using just the auto sense cycle. I just scrape large pieces of food into the garbage disposal or trash can and I will occasionally lightly rinse dishes that have large gobs of tomato sauce, sour cream, etc on them but mostly nope, in the machine they go as is and I don't even run it every day, more like every three days or so. I use Cascade platinum pods because they perform well in hard water, and Finish Jet Dry rinse aid. Near perfect results every time. It's amazing the difference a good, well-working dishwasher makes.
 
Yes, rinsed a plate that only had Bell Pepper Seeds--Naughty

no, don't rinse!

 

--my daughter sure got a lot of reprimanding from me because of her doubting the dishwasher would wash away pepper seeds, so I told her how we put even harder stuff through there and it all comes out super clean!

 

--end of story...
