How To Install A Dishwasher

As we mentioned on Monday, before we hopped on a plane yesterday, we tackled our bisque colored dishwasher. And let’s just say the stainless one is a crowd pleaser (we like it, but Clara loves it). We’ll get to that in a moment.

We had been telling ourselves that it would be better to do this once the new floors went in (so we didn’t accidentally trap it behind the new cork boards or something). But then we realized that was a dumb excuse because we could just slide it on top of a few cork planks so it would be the same height as the rest of the floor once it goes in. Plus if the new dishwasher box stayed in the office any longer we’d risk it becoming a permanent side table substitute in there. It does have a large surface area after all (so things tend to pile up on top of it)…

We have never installed a dishwasher. It freaked me out a little bit because it was plumbing + electrical + tight space. Not to mention that I didn’t want to ruin a $380 appliance in the process. But after watching a few videos on YouTube, I was feeling a bit more confident about it (this one and this one were particularly reassuring). So when Clara went down for a nap on Sunday we gave ourselves a little pep talk and dove in.

First up, we turned off the hot water supply and electricity to the dishwasher. Embarrassingly enough, this step alone took us a good 15 minutes because our breaker boxes (we have two) weren’t labelled correctly and it took us lots of trial and error (and trips to the basement while on our cell phones to communicate) to make sure I wasn’t going to electrocute myself.

With the water and power off, I unscrewed the access panel along the base of the old dishwasher. Prepare yourself for some less than clean floor photos. Sorry. (There’s been a lot of DIY action going on in here, so the old vinyl floors aren’t exactly pristine).

Here’s the view behind the panel. Looks like a party, right?

Using a wrench I unscrewed the water supply, keeping a rag handy to catch some leftover H20. This too took longer than expected because of the cramped space.

With the water supply off, my next step would’ve been detaching the drain hose from the disposal under the sink. I didn’t do this (yet) because I had already detached it under the dishwasher just because it was in the way of my wrench. And at this point I was trying to undo as little as possible just in case I needed to retreat (i.e. give up).

All of the plumbing was disconnected, so next up was electrical. The wiring is all encased in a little metal box that was removed pretty quickly with a little screwdriver action.

From there I just unscrewed the wire nuts and, just like that, I was done with the electrical parts of the old dishwasher.

Now I just had to focus on getting the dishwasher out of its home. First up, lowering the little adjustable feet so that it wasn’t so tight against the bottom of the countertop. Don’t mind the dinged up baseboard – we’re waiting to caulk/putty/touch that up until we install the new cork floors and add new quarter-round. Then it’ll all get gussied up.

Next I had to remove where it was screwed in. In most cases I think dishwashers are actually screwed into the underside of the counter. But ours was screwed into the cabinets on either side (maybe because we used to have granite counters?). I just popped off a little plastic plug and unscrewed away.

A shimmy and a shake later, and our bisque buddy was no longer clashing with our cabinets and counters. Oh, and even though these aren’t the new floors, I still pulled it out on a piece of cardboard for added protection and easier sliding around.

So we were left with an empty hole full of new dishwashery potential.

Before the new dishwasher could go in, though, I wanted to make sure to prepare for the new floor. So I roughly cut some pieces of our new cork and slid them in there so that the new dishwasher would sit at the height of the new floor, not the old one. Because if it sat behind the new floor boards it could make getting it out for repair or replacement very difficult (or impossible) down the line.

With the floor boards ready, out came the new energy efficient dishwasher (which we bought among a bunch of other on-sale appliances back in October).

It was at this point after reading the (very confusing) directions for the new dishwasher, that we realized that we needed to swipe a piece from the old one – a 90-degree elbow – to help route the water supply line into the dishwasher.

I’m not sure why these just don’t come in the box (I would’ve been super annoyed if I had had to go to the store just to buy one), but whatever. At least it gave me the opportunity to learn it’s WAY easier to work on a dishwasher when it’s pulled out and accessible on all sides. See – even the lighting for photos is better!

With the elbow attached, I could reattach the water supply line. Lucky for me, it was long enough to do this with the dishwasher still pulled out. Sure made maneuvering the wrench easier!

Here’s the point where I had to disconnect the old drain hose from the disposal and reattach the new one. Theoretically I could’ve just attached the old hose to the back of the dishwasher. But if one of my new connections were to leak, I wanted it to be the one under the sink (where I can see it) and not the one hidden in the back of my dishwasher.

Plumbing attached? Check. On to the electrical. I learned through this that I was missing a strain reliever on my wire, so I did have to run out to the store to grab one. It basically holds the wire in place at the dishwasher’s electrical box, removing any strain on the actual wire connections (since we don’t want those pulling apart!).

I attached the strain reliever, screwed the wire nuts back on to attach the wall wire to the dishwasher wire, and reattached the box cover. Then I held my breath as I went back down to the basement to turn the power back on and make sure my electrical work actually, well, worked.

Houston, we have liftoff.

I also turned the water back on and watched all my plumbing connections to make sure I didn’t have any leaks. Good thing I checked. I did have a small one around that 90-degree elbow. I had to detach the hot water supply, give the elbow another 360-degree spin and reattach everything. Then – after another leak check – I was good to attach this baby to the underside of our counters. Whew.

And just like that my friends (and by “just like that” I mean “three hours later”) – we had a new dishwasher! As Sherry mentioned in her post on Monday, it’s really nice to have something stainless on that side of the kitchen because it makes for some nice balance (the old fridge was almost right next to the old dishwasher, but our new arrangement makes for a better work triangle and looks better too).

And speaking of washing things, Clara got a hold of a paper towel while we were snapping these pics and went on a “wiping” spree. I don’t think she managed to wash any dishes but, well, you’ll see how much ground she covered…

Balance has finally been brought to our appliance triangle, and our dishwasher no longer looks dingy next to our white cabinets. Good stuff.

And the installation process wasn’t nearly as bad as I had prepped myself for. Sure, it did take a bit longer than I had hoped (though it did include one unplanned trip to get that strain reliever), but what project doesn’t?

Here’s the view from the office. You can’t really tell in this picture, but it’s also nice in person how the stainless finish plays off of the sink, faucet, and our new mercury glass pendant light.

And it’s worth mentioning that this has the same protective finish that keeps fingerprints off of it (more on that here). It’s very helpful in our household, since a certain someone’s cleaning techniques still leave a bit to be desired.

Functionally the dishwasher is pretty much the same as our old one. But I do love the added timer countdown on the front of the machine and the note that actually says “clean” when they’re clean (no more calling to each other across the house to ask if they’re dirty or not).

Oh, and you may have also noticed in these pictures that we’re sporting a new dish towel. It’s from Target, and we thought it was a fun addition. Clara agrees.

Who doesn’t love a little black and white chevron? Especially with soft penny tiles in the background to set it off.

Again, Clara’s on board with the decision. Can you tell someone recently learned to smile for the camera on command? “Can you show me your teeth?” has become a very handy phrase around here lately.

Has anyone else ever tackled a dishwasher installation? Did you have smooth sailing? Was there that obligatory unplanned trip to the hardware store? Did it take longer than you thought? Was there a tiny but correctable leak? Did you just learn how to smile on command?

    My husband is a great DIYer who no longer has time to do these fun house projects for me since starting his own business. (I mourn the loss of his skills in the home!). Now he’s an entrepreneurial DIYer in the technology world. He’s installed dishwashers before, and I suspect there are days when he as a captain of industry would prefer to be doing just that! Way to go, Jon! Your kitchen looks gorgeous!

    This is perfect timing! I just installed a dishwasher (or rather watched my boyfriend do it). The whole project turned out to be a little tough because the dishwasher sat on the concrete slab. Apparently the floors were installed after the dishwasher! Now I’m having a bit of a hard time making sure it sits level on the floor. Your post has definitely given me a few things to consider. Thanks! :)

    I kept wondering about the dishwasher. It looks great, just like the rest of the kitchen. But, I must admit, nothing compares to that smiling face of Clara’s at the end of the post!

    Ahhh, we installed the exact same dishwasher in our house on Saturday! It was very easy to install, but then again, my husband is a pipefitter…the hardest part was making it even on the floor and with the cupboards. My husband laughs because I admire the new dishwasher everytime I go in the kitchen now and I say “oh, you’re so pretty.”

    The dishwasher that came with our house died last year and we bought a replacement. Unfortunately, the prior owners had tiled the kitchen and the old dishwasher was VERY difficult to get out, since as you described in this post, it was pretty barricaded in. My husband had to use a hacksaw to saw the feet off the old one to get enough clearance to haul it out and in the process it damaged our counters.
    I wish I would have thought to put tiles in the empty space before our new one went in….

    Glad to see you’re training Clara to clean so young. Isn’t that why we have kids, to clean our house and fix us breakfast?!
    Can’t wait to hear all about the show!
