Introduction: Demon Dishwasher for Cheap

Are you a maker who likes to cook? Are you tired of looking at all the cool food you'd like to make but don't want to wash the mounds of dishes it will inevitably require? This instructable is for YOU!

It came about because I want to make fantastical meals for my not-so-interested-in-cooking but very appreciative Le Boyfriend. I decided that since the only thing stopping me, essentially, was 1) I can't buy ALL the exotic food, much as I would like, and 2) I hate washing dishes.

So obviously the first step was to have a heart attack, not because of Fat, Sugar, and Salt from cooking, but because dishwashers are expensive. And they get crap reviews! There's $500 models for apartments that have crappy production, they don't drain, they don't wash dishes well. And they're bulky. I do not have enough space for a countertop model.

Let's make our own for 1/4 to less than 1/10 of the price you'd pay for a "real" dishwasher. I got the idea for this build by looking at the abstract for the original dishwasher patent filed in the 19th century- a rich housewife got her husband to make a "rack and water jet" system for washing dishes because she was tired of the servants chipping her fine china. 

Step 1: Collect Stuff

After your heart attack and resurrection, you need to get stuff. A lot of this stuff, you might have laying around. If not, well, it's not that expensive. I paid about thirty dollars for this project, out of pocket. Pretty good deal, I think. Everyone smiles when I show off this project, and that's priceless.

Here's what I recommend you get: (mostly but not all pictured)

-dish drying rack (a housewarming present from Le Boyfriend's mom, I'm pretty sure they can be cheaply had. We didn't use it before this so hooray it now has a purpose in our life!)
-Plastic storage bin big enough to fit the drying rack with ample wiggle room. Ours fit the rack and had abour 4-6 inches free which was perfect
-lawn sprinkler (I used a $6 Discovery Kids version I got from Rite Aide. Here it is on amazon. I have no idea how good it is as a lawn sprinkler, but it's a really fun dishwasher jet! The purple drum is all spinny, which is the type of sprinkler I was looking for, and originally I was nervous about the wiggly tubes but as it turns out, they reach the back pretty easily. They are also at fault whenever water seeps out the top. Someone should tell me how I OUGHT to do seals)
-gasket (I got this later)
-Aquarium silicone seal (because for some reason tub seal dissolves. I think they wanted me to buy a separate product to cure it. laaame.)
-hammer for tapping in brads
-hacksaw for cutting
-I used a cheap soldering iron to cut the drain hole because I was too impatient to go at it with a knife.
-utility hose
-hose end
-dishwasher hookup (take your aerator off the sink and take it to the hardware store and make sure the dishwasher hookup will match the hose and the aerator. )
-sharpie
-scissors
-tape, if you don't have an extra pair of hands

Step 2: Cut a Notch for Your Hose

Using the hack saw, cut out one of the corners of your plastic bin to admit the hose comfortably. There is water in the bin because I tested the lawn sprinkler before starting, to see if it worked. The whole floor got clean on that day!

Here's a video of the test, and another video of how I got the porch clean too.



Step 3: Cut a Hole for the Drain

The sharpie is to plan out how big your hole will be.

Don't do what I did. Don't try and be cute like "I'm going to have a hose for the drain, too!" It added a week of non-consecutive work time because the short version of the story is that utility hoses are heavy enough that unless you have a super drill bit and a drill (I do not have these things because I have to pay tuition) you are never going to make a seal that will withstand the force that the hose flexing will exert on the box. So don't even try, unless you do in fact have a super drill.

Just placidly, zen like, cut a hole instead. Mine was on the side to make a hose easier, but you could put yours on the bottom.

Also, if you have zero patience, do not use a steak knife because you will crack the plastic. Use something like a cheap soldering iron and a face mask for the fumes because you can mend cracks that you made because you're impatient and want to cut easily. If you are patient, unlike me, use a knife that is suited for the job. I'm getting a rotary tool for my birthday.

Step 4: It's Hard to Hold a Lid On

So this is actually the part that I had/have the most trouble with. Anyone who has any suggestions are free to tell me what's up. Also, I'm going to do this, you ought to do this: get a hot glue gun or some wire cutters or something. I don't have these things yet, but I'm going to explain why it's a good idea to have them for this step.

I tried a LOT of different ways to seal the lid and right now I'm on the one that is most effective, aquarium seal all over a gasket that's been tapped into place with a hammer by included wire brads. Ignore the drain hose, I was still under the impression that was a good idea when I took this picture.

As you can see, wire brads extend down beneath the lip. Where everyone wants to hold the box. They've bitten me, so I recommend cutting them down and covering them with hot glue. I'm going to do this. You should too. It hurts like a piece of hot wire has been shoved into your finger, which if it happened while the dishwasher was running, it would be. Yep. Right under your left thumbnail. When you're left handed. Don't be an idiot, like me. (My thumb healed in a couple days. It wasn't that deep, but I have an appreciation for why the Chinese Bamboo Torture chooses this place for insertion.)

Also, aquarium silicone seal will get everywhere and it's hard to get off. It'll rub off after it's cured, though. I have an old hanky that it peels off of, and I managed to get it off my hands. The floor, for some reason, was really slippy though for a few days.

Step 5: Put the Whole Thing Together!

After waiting an excruciatingly long day for the silicone to cure, it's ready to be run.

Replace the aerator of the sink with your hookup (I've taken to holding a dishrag in between my hand and the hookup when I do this as I discovered the hard way that it's possible to cut yourself on the threads. That was my right thumb, it's still healing, just like a really bad papercut. That runs along the side of the knuckle.) and attach the utility hose.

Put the sprinkler, the rack, and any dishes you want to wash in the box. Everyone has their own way of stacking the dishes, so we'll leave that part up to personal interpretation. Do a line of normal dishwashing liquid down the long way, and if you have a lot of silverware that needs to be washed, you can do another horizontal line, but you really don't need a whole lot of soap.

Especially if your water is not temperature capped. My water is not temperature capped, so I use the soap more to get any food I missed wiping off. The water kills any buggers.

(The story behind the tiny bottle is that I stayed at a hotel once that had a kitchenette and a little sample sized dishwashing liquid bottle. If you've ever read Mindless Eating, by Dr. Brian Wansink, you've seen how he proved that if there is more, we pour more, and since dishwashing liquid is expensive, I just keep the little bottle stocked with dishwashing liquid and keep the big bottle hidden. In this way, I only have to buy dishwashing liquid every two and a half months.)

What are the dimensions of the storage bin used?

author
PikeMinnow (author)TotalBalance2015-08-31

probably around 18" w X 24" l X 12" h

It needs to admit a dish rack and a sprinkler

I really like this concept, gives room for a lot of other ideas to implemented with it.

Does this dishwasher actually work in an objective sense? I understand that it probably works about as well as any other apartment-sized dishwasher. But, does it actually clean anything more than the exposed surfaces of the closest dishes?

That really depends on how I stack it. I've been experimenting, and it cleans the exposed surfaces of the closest dishes most effectively, and it'll get cups pretty well, (a lot of times air will get trapped under them and if the water level raises high enough, they overturn and rinsing takes a bit then), but for the most part, if it's in the main area, it'll get clean. The problem is mostly with the flatware rack. The flatware rack in the larger dish rack only has drainholes in the bottom, so it very effectively protects the flatware from getting cleaned. I plan on cutting slits in it with my new rotary tool and stacking it such that all the in-mouth/food-touching ends are towards the top.

The biggest problem I find I have is that I'll run it, only to find that either I or le boyfriend absent-mindedly stacked something that hadn't been wiped, such as greasy spaghetty sauce plate or cream-cheese bagel cutting board. The dishwasher isn't very good at removing chunks of dried-on food. IIRC this is a problem most dishwashers share.
