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

I was ready to riot if I didn't see TC in the comments.

I was shocked that I had the opportunity to post it, to be honest.

It’s funny cause i was just talking about this video the other day with someone who didn’t know you have to run the tap hot before starting the machine. It’s just such a good video.

That was fantastic, thanks!

Some of the key things were to put separate powder in for the pre-wash (mine doesn't have a separate pre-wash section as far as I can tell), and to not put so much detergent in. We have soft water, and apparently that means if you fill the thing up (or use a tablet/pod) then you might be using too much detergent which means it might not all come off in the final rinsing stage.

Then you can just dump the pre-wash detergent directly in.

Tips I've learned that helped:

  • use detergent powder instead of pods. It let's you experiment with different amounts and dial in the right amount for a run. Generic is fine, they all do about the same amount of work.
  • Run your faucet till hot water comes out, it makes it so the pre-rinse has more ability to soften crud on the surface of the dishes.
  • pre-rinsing the dishes isn't necessary for cleanliness, but scraping food bits off will mean your debris filter fills up slower so you don't have to do the gross task of emptying it as often.
  • add detergent in the dip on the door. This gives the pre-wash yet again more ability to attack food bits on the first cycle.
  • USE RINSE AID. I helps the dishes dry at the end of the wash.

Running your faucet only makes sense if your dishwasher is also hooked up to warm water. (In Germany) I've only seen them connected to cold water.

[–] Bytemeister@lemmy.world 11 points 1 week ago (3 children)

It's an American thing. Our dishwashers get hot water from the line, there is a heating element, but it is not very powerful due to our lower output electrical sockets.

I've heard other countries have washers that are powerful enough to heat their own water, which is why they are attached to the cold water supply.

Do you run the water in your sink until it’s hot before turning on the dishwasher? Most kitchens are set up so they use the same water line, and starting with cold water if you don’t do it will make it clean worse.

[–] waigl@lemmy.world 42 points 1 week ago (4 children)

That's a thing with diswashers in North America, but not in Europe. In Europe, dishwasher are almost always connected to the cold water line only. OP seems to be posting from New Zealand, I don't know how they handle it.

[–] Ephera@lemmy.ml 32 points 1 week ago (3 children)

It's handled like that in North America, because their mains electricity doesn't output enough juice to operate a water boiler at a reasonable speed:

https://en.wikipedia.org/wiki/Mains_electricity_by_country

So I imagine, in pretty much the rest of the world, it works like you described for Europe...

[–] GreenCrunch@piefed.blahaj.zone 8 points 1 week ago (1 children)

We don't need high voltage actually. By pumping cold water through the block of an honest American diesel V8, it can be heated quickly. Every house includes one for this purpose. I love the sound of it starting in the morning to heat water for my shower.

Confirming, connected to cold water here in NZ.

Interestingly, where I live I have never, ever seen a dishwasher installed with a hot water line. Even the cheapest dishwashers heat their own water, and around here we apparently always plumb them to the cold water for some reason, even though I'm sure plumbing to hot water would at least save time if not get better results.

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

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.

[–] TrapRag@lemmy.world 27 points 1 week ago (4 children)

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 πŸ‘ˆπŸ‘ˆπŸ˜Ž and backed with science.

Lmao you right, I was being a little too casual. Gotta put some respec on his name πŸ˜‚

Also very fair point but happy to spread the word just in case

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!

Use prewash detergent

Powder detergent only for both washes

Stack the dishwasher according to the manual

Don't leave your dishes for a week before putting them in the dishwasher

[–] wreckedcarzz@lemmy.world 26 points 1 week ago (1 children)

You can only choose one of the four

  1. use powdered detergent, the cheapest available. NOT PODS
  2. Buy rinse aid.
  3. fill the rinse aid compartment
  4. 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.
  5. if theyre still coming out with residue, consider cleaning/descaling the jets, the filter, and try putting less dishes in.
  6. 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.

[–] FlexibleToast@lemmy.world 11 points 1 week ago (2 children)

Are you adding detergent to the pre rinse, or are you just throwing in one of those crappy packets?

[–] Dave@lemmy.nz 9 points 1 week ago (1 children)

Just watched the video someone else posted. My machine doesn't have a pre-wash section as far as I can tell, but I'll throw some extra powder into the bottom for the pre-wash cycle and see how it goes.

Yp, started doing that and it worked in mine. You'll need to do some trial and error to get the right amount, but TC is right.

I swapped $40 pods that gave me 80 loads for $8 powder that lasts hundreds

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.

[–] meejle@piefed.world 9 points 1 week ago (5 children)

This was on QI.

The enzymes in the dishwasher tablets need some dirt to glom onto, to be able to work. So pre-rinsing can make them less effective.

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.

Most dishwashers have a pre-rinse program, adds ~5min to the duration. It does get rid of lime residue.
