Apparently pre-rinsing confuses the dishwasher or something. Not doing it leaves me with residue all over the other dishes though 🤷

- use powdered detergent, the cheapest available. NOT PODS
- Buy rinse aid.
- fill the rinse aid compartment
- fill the given soap cup all the way AND the prewash. Sometimes the prewash is just an indention in the little door flap for the soap cup. If you dont have one, just sprinkle like 30% of the amount of powder you put in the cup.
- if theyre still coming out with residue, consider cleaning/descaling the jets, the filter, and try putting less dishes in.
- if that all fails, read the manual. The dishwasher company wants it to work. They know how it works. They wrote a guide. Look up something like “whirlpool washomatic manual” or whatever is printed on the front of it/inside the door. Mine has a sticker with instructions.
Ive dealt with 5 dishwashers that “dont work” and after kindly instructimg the owner over the course of maybe 15 minutes, they save 30 mins a day washing dishes. Still less water/energy (water heater) to run twice than handwash once.
Also run the tap on your sink until the water turns hot, then start the dishwasher.
A majority of the gunk removal happens during the pre-wash cycle. Hot water greatly helps with this.
fill the given soap cup all the way
One thing I’ve learnt from this thread is that this isn’t necessarily right. Its size allows for people with hard water, but if your water is soft then by filling it all rhe way you are likely using too much, which can lead to residue on your dishes. For soft water, half filling is apparently often plenty. Which is another reason to use powder not pods.
Powdered dish detergent and running the water until it gets hot before starting the dishwasher seem to make a difference for me
My dishwasher somehow checks how dirty the water is after the first rinse and adjust ms the washing time accordingly, so getting ketchup and sauces from the plates before makes it run shorter.
That may save some time but I don’t think it’d save water. Dishwashers don’t constantly add new water. Itll add water for a rinse, wash it out, and then more water for the clean. I’m sure some dishwashers do a third cycle as well
i always, always set my dirties in the sink, drizzle some dawn in/on and soak them in hot water mostly overnight but a minimum of five hours. rinse and load and they come out spotless every time
That sounds like almost as much work as washing by hand!
its not, though. takes less than a minute per dish
So does washing by hand 😆
It’s also basically doubling the water usage.
It has a purpose when cleaning by hand
I, uh, have to hand wash all of mine so
i rent a house that does not have a dishwasher and i hand washed everything for a while.
i bought a small countertop dish washer, it’s like 2x2 foot or so. you have a house that you stick on the sink tap.
it’s large enough to handle like 3-4 days of dishes, uses less water then hand washing by a lot, and saves so much time, takes not much power.
i just load it up, put some soap inside the trap and some outside, run the water through the pass through until hot and let it run. it cost me about $250 when i got it. it’s been running well for 5 years now
Residue is a sign of too much soap in the dishwasher. Try reducing the amount of soap. Also, it massively helps to put a little bit inside the chamber and not just the soap compartment. The dishwasher has two washes, pre-wash and main wash, and without soap, pre-wash will be almost useless. With soap, it will drastically reduce the necessary amount of soap in the main wash, meaning no more residue for you.
You mean detergent right?
Apologies for the youtube link but this guy fits in nicely with the lemmy crowd and made a 40min video about optimal use of dishwashers and detergent. He does promote a specific powder detergent… but its from a good company 👈👈😎 and backed with science.

You mean detergent right?
Without double-checking your pedantry (or language barrier) via web search, isn’t “detergent” a type of soap?
That is excellent question of semantics. I dont mean to argue semantics but rather clarify dish “soap” vs dish washer “detergent” as that could be the difference between a successful wash that doesn’t leave residue vs any alternative result.
Hmmm I wonder who it could be.
On an unrelated note, down with blue Christmas lights.
“This guy”!? How dare you disrespect Alec like that! :P
If you’re nerdy enough to be on Lemmy, you’re likely nerdy enough to already be a fan of Technology Connections; just sayin’.
Lmao you right, I was being a little too casual. Gotta put some respec on his name 😂
Alec Watson puts out some top notch content
Also very fair point but happy to spread the word just in case
lol fair enough
Someone else posted a video that covered this. Some dishwashers (not mine) have a pre-wash spot for putting the soap. In the video, the guy had his spot actually on top of the soap door, so it would be measured but falls straight in with the dishes when you close the door for the pre-wash. He said in the video to just add a tablespoon of dishwashing powder on the door or in the bottom if yours doesn’t have a prewash spot.
I have learnt a lot from that video and all the comments here!
It’s also worth seeing if the dishwasher you have heats up the water or if it just pulls hot water from the boiler.
You’ll be able to tell by seeing which pipe connected to, if it’s connected to cold water then you’re okay, you’re not American and you can relax.
Some things you can just put in, some things need a long soak and a steel wool scrub.
Fond on stainless? Baked on protein? Ancient debris? You might need to do it manually.
I don’t know, man, just put it through and if it doesn’t come off, LEARN what you can and can’t like a normal human being, jesus.
A good way to start, if you’re an infant, is to soak all your dishes for like 6-12 hours, and inspect to see what comes off easily and what doesn’t.
All this talk about soaking or not soaking is like mormon young adults trying to bend the walls that skydaddy built.
I have an old (must be 20yo) budget bench dishwasher and never have any issue with anything not being clean. Never done pre-wash and often overpack it.
My dishwasher literally doesn’t have a pre-rinse cycle, the first wash is the main one with the powder, so I get to avoid this whole conundrum! By which I mean, I do quickly wash them by hand if there’s any obvious gunk, and no one would realistically tell me not to.
To those curious, it’s this countertop one: https://www.midea.co.il/product/mdwmt030sw-w-il (couldn’t find a product page in any other language)
The compartment for the detergent has no lid, so the powder drops as soon as you close it.
It also does not have anywhere to put rinse aid, but a bottle of some was included when I bought it new. Great attention to details.

The whole point of this topic is that you’re not supposed to have to do that 😅
I know, but for my dishwasher specifically, you kinda do :D
I never pre-rinse and I never have any problems. Not using pods and adding soap to the pre-wash cup as per the manufacturer instructions made the real difference.
Used to have issues. Alec has solved them all for me. Great video.
Using regular dish soap for this will end up in a disaster.
I can report back since my ex did it once. Suds came out of the dishwasher while it was running, otherwise no big deal. Worked fine afterwards, didn’t develop any leaks or anything.
She also used liquid hand soap for laundry once, smelled a bit funny and might not have gotten as clean as otherwise, but otherwise nothing bad happened
That’s not a typical reaction. Either there was only a non existent amount of dish soap or the thing wasn’t left running long enough for it to be really bad.
It almost always results in suds being EVERYWHERE and the same thing happening over and over again if the dish washer isn’t cleaned properly afterwards.
I suspect it was a fairly small amount since, despite being an idiot in general, she at least knows that dish soap suds a lot. She’s washed dishes by hand at least 5 or 6 times in her life I know for sure (mostly she has her men do things like that, she’s got no time or energy for chores (or a job for that matter)).
I overfilled with regular dishwasher detergent once and triggered the overflow sensor. The dishwasher drained itself correctly, but bubbles in the little tube kept the float locked in the overflow position until they all popped, hours later. The soap residue left in the sensor bubbled up for several cycles afterward, repeating the problem. You can, theoretically, unscrew it from its mount and tip it forward to make the bubbles pop faster but that sounded like a recipe for disaster.
I cannot imagine what dumping regular-ass dishsoap would do to my dishwasher, but based on the above I’d probably just put a round in it and look for a new one.
Detergent = soap but you’re right, regular dish soap does not belong in the dishwasher and will result in a huge mess.
My dispenser door is permanently jammed Open,so i had to reluctantly Switch to pods for the Timed Release. Powder is better imo.
Watch the video someone else posted in this thread. It briefly touches on timed release pods. They tested and the whole thing disolves at once, within seconds.
Don’t bother. Delayed release is bullshit. Just dumping powder in there should get the same result.
People who saw the TC video reading this:
Gotta run that water till its hot, and use the powder, brother.
Again with this America-centric view
Ah yes, Dishwashers and their operation. The quintessential americana. Surely no one else in the world has dishwashers but America.
Username checks out.
My dishwasher doesn’t use hot water, it’s got an heating element.
He’s poking fun at our anemic half phase electrical system. In places with 220/240V electrical is the norm, electrical heating elements are more powerful so there’s no need to get the water warm using the kitchen tap before running the dishwasher.
Oh you (rest of the world), with your 220vac everywhere and your “yeah electricity can heat that up” attitude.
I’ll give you the gift of super advanced technology!
I think the 220vac is just Europe, isn’t it?
Just a note: Australia and NZ are ‘officially’ 230v but are in reality 240v.
We were historically 240v and nothing actually changed at an infrastructure level, just the standard which says we’re at 230v -6%/+10% (which allows for up to 252v, ie. 240v +5%, the old standard)
Pre-rinsing is the hill I’m willing to die on.
I’d rather pre rinse then always be cleaning all that rotting food out of the filter.
If I don’t pre-rinse, no matter how clean my filter is, I end up with little bumps of gunk on all my plates and bowls. You can’t see them, but you sure as shit can feel them. There’s no way I will ever stop pre-rinsing
Look up the turbidity sensor
If you haven’t cleaned your filter recently I will recommend you double check it. It’s probably not it, but it’s an easy thing to check
Also refill the dishwasher salt!
Another tip is to pop out the spray arms in the machine, and clean and decalcify them.
(If you wondered “what’s dishwasher salt”, you probably have a lot of blockage in the spray arms, and get less pressure as a result)
Not all machines can use dishwasher salt and not all areas need it. It’s apparently for built in water softening. In the US for example areas with hard water typically have whole home water softeners.
I live somewhere with soft water so dishwasher salt isn’t needed. I used to live in Ohio where the water is generally fairly hard, and there every house had a water softener. That said if you don’t have a water softener or soft water (or you just get mineral buildup in places with water) check if your dishwasher has a salt compartment
As someone who never reads manuals. This.
That dishwasher isn’t designed to be self-cleaning – it needs help. Clean the filter regularly. Maybe every other load depending on how you pre-wash.
Same vibe for a lint filter in your washing machine. I think many people check the dryer lint trap, but the washer also has one. And the dryer vent hose will collect lint.
There are air filters in your furnace, probably, that need to be checked too, not just the intakes in a few rooms; and the AC drain line needs to be cleaned occasionally or it will back up and make a water mess.
There are just a thousand maintenance tasks that we are presumably supposed to just know, but no one told us, and can become serious problems when they are ignored. As the world becomes more complicated, there are only more of these.
lint filter in your washing machine
TIL… where would this be?
My front-load washer had a panel on the bottom that exposed the filter. It got clogged with a hair tie and pet hair - the washer wouldn’t drain and I had to do it manually. Was quite a pain.
I found this article showing common places, but also TIL that maybe not all washing machines will have one.
TY for the link! I looked all over on my unit and couldn’t find jack. Just the normal fabric softener and bleach receptacles. will check out the link.
“It’s probably not it”? After 30 years of dishwater experience I am convinced that it’s always the filter.
Yeah right like if my dishes aren’t coming out right that’s the first place I look.
It’s pretty simple, really…if it’s draining too slow and the dishwasher doesn’t realize it, it’s gonna spray dirty water far later than it should band.
Where my washer seems to struggle is shit that dries on real good. Parfait is probably the worst. Which is funny, because e’rybody loves parfait.
Ok fair, it’s almost certainly a factor here, but may not be the only cause
Most dishwashers have a pre-rinse program, adds ~5min to the duration. It does get rid of lime residue.
