Dishwasher Installation Guide

So… You Got a New Dishwasher?

First off — congrats! That shiny new dishwasher means no more dish mountain in the sink and definitely fewer arguments over whose turn it is to wash up. But here’s the thing: before you can kick back and let the machine do the dirty work, you’ve gotta install it. And yes, that part can feel a little intimidating at first.

Don’t worry though — it’s totally doable. Whether you’re replacing an old one or installing a brand-new unit in a fresh space, I’ve got you covered. Let’s take it step by step, no tech jargon, no pressure.


Step 1: Prep Like a Pro

Alright, before you even unbox that dishwasher, you’ll wanna make sure you have a few key things handy. Nothing’s worse than being elbow-deep in installation only to realize you’re missing a hose or the right screwdriver. So here’s your quick checklist:

  • ✅ Adjustable wrench
  • ✅ Screwdriver (usually Phillips)
  • ✅ Dishwasher installation kit (comes with most new units or can be bought cheap online)
  • ✅ Teflon tape (for sealing water line threads)
  • ✅ Bucket and towel (because water will happen)
  • ✅ Buddy to help lift it (unless you’re feeling like Hercules today)

Oh, and this one’s big — turn off the water and electricity to the dishwasher area. You don’t wanna find out the hard way why that matters.


Step 2: Out With the Old (If You’re Replacing)

Already have a dishwasher? Cool, let’s take it out. First, disconnect the power supply, water line, and drain hose. If you’re unsure how, snap a quick photo of everything before unplugging — future you will thank you.

Gently slide the dishwasher out. Might need a little wiggling or someone to hold the cabinet door open. Lay down a towel underneath to avoid scratching the floor or spilling any leftover water.

Now give the space a quick wipe. When else are you gonna clean behind your dishwasher, right?


Step 3: Hooking Up the New One

This is where it gets real. Ready?

1. Connect the water supply line

Use that Teflon tape on the threads of the elbow fitting (comes with the install kit), then connect the water line. Tight, but don’t overdo it — no Hulk strength needed here.

2. Attach the drain hose

Make sure it loops upward before going into the sink drain or garbage disposal — this prevents nasty backflow (gross, but important).

3. Plug in the power

Some dishwashers hardwire, some use a standard plug. If you’re not sure what yours does, check the manual (yes, the paper thing you tossed aside earlier).


Step 4: Slide It In (Carefully!)

Once everything’s hooked up, it’s time to slide the unit back into place. Go slow — you don’t wanna kink the water line or crush the drain hose. Keep your eye on the cords and tubes underneath.

Once it’s snug in the space, use the mounting brackets to secure it to the cabinet or countertop so it doesn’t wobble when it’s running.


Step 5: Test Time!

Almost there! Turn the power and water back on, and run a short cycle to check for leaks or weird noises. Stand by with that towel, just in case something’s not sealed right.

No leaks? Quiet hum? Nice. You nailed it.


Finally: Look at You, DIY Star 🌟

Seriously — give yourself a high five. You just installed a dishwasher. That’s adulting at its finest. From here on out, it’s sparkling dishes and way less arguing about “who left the fork in the sink.”

And if things didn’t go perfectly? No biggie. That’s what adjustable wrenches and YouTube videos are for. You’re learning. Next time, you’ll be the one showing someone else how it’s done.
