My dispenser door is permanently jammed Open,so i had to reluctantly Switch to pods for the Timed Release. Powder is better imo.

Don't bother. Delayed release is bullshit. Just dumping powder in there should get the same result.

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. Why would this matter? Dishwashers aren’t connected to the hot water line.

Seems like some American dishwashers are connected to the hot water line. Probably because the power available from a standard electrical outlet can't heat fast enough.

"It's probably not it"? After 30 years of dishwater experience I am convinced that it's always the filter.

Ok fair, it's almost certainly a factor here, but may not be the only cause

I used powder for years and it worked okay. However I was always cleaning my filter and the inside of my dishwasher seemed a bit grungy. On a whim I decided to try one of the most expensive pods. The difference was night and day. My dishwasher looks much better, and now when I clean the filter there's barely any gunk. Some of the pods definitely have more effective product (enzymes?) that the p...

Were you using the expensive powder?

How often do you use your dishwasher? I use mine about 2-3 times a week, so if we go with 3 that's saving like 40 bucks a year, assuming perfect measurements and no spilling of the powder. That's not enough of a difference to fret over.

Daily, occasionally twice a day

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 ...

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.

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.

Using regular dish soap for this will end up in a disaster. Edit: Lol, what kind of idiot downvoted this. Go ahead, use regular dish soap in a dish washer, and PLEASE report back. XD

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

Pre-rinsing is the hill I'm willing to die on.

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

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

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.

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.

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.

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.

You could spend that saved $40 on the powder, and now you're sitting on ~4 years worth of detergent.

Do the same for washing clothes.

Buy foodstuffs in bulk when able.

Same with personal soap/shampoo/etc.

Now you're sitting on few hundred $ in savings a year.

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.

Electricity in the usa is not weaker than Europe. Since the voltage is half as high, it just takes double the current to do the same work. A heater running 220v at 5 amps and a heater running 110v 10 amps will work exactly the same.

That is actually a perfect example of what I'm saying. You immediately assumed that we're talking about a "rated" "appliance" and not, for example, a "screw" "driver"

I don't need 4 years' worth of detergent taking up space. I'm happy to have a little box of pods I replace occasionally when I go to Costco.

Yeah, I could spend a bunch of time and effort maximizing my savings. But I spend 50 hours a week plus a commute earning money, and that's all the time I'm devoting to it. When I'm off the clock I'm done trying to make or maximize income. I spend that time living. It's worth $40 a year to me to not deal with powder.

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.

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!

We have 230VAC (on all outlets) instead of your guys' puny 120V, so our dishwashers aren't handicapped out of the box and can heat their own water properly. I feel like having to run the tap before doing dishes is an L for the US, not Germany/Europe?

Wat? We have 230v also. We have both 120v and 220/240.

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.

Not for washing. Usually there will be settings like quick wash, normal, heavy and "pots and pans". There is a high temp and low temp option, but that is for drying the dishes.

It can be for anything you like. Dishwashers, dryers, heaters, hot water tanks, ac units, ovens, stoves, welders, car chargers, air compressors, hell, I've seen 220v coffee makers. If an appliance needs 220 it can be supplied.
