How to Install a Dishwasher - Whirlpool WDF530PLYM (WDF530PAYM)

I recently bought a new Whirlpool Dishwasher from Lowes after my old GE dishwasher washed it's last dish.  The Whirlpool dishwasher model I bought was WDF530PLYM, which is very similiar to the more common Whirlpool model WDF530PAYM that is found at other retailers. 

I decided to install the new dishwasher myself, and in the process learned a few things that would have made the dishwasher installation go much smoother and quicker.  So if you decide to install a dishwasher yourself, here's my recommendations:

1. After deciding on the Dishwasher model you are going to buy and install, make sure you first find and download the Dishwasher's Installation manual.  Usually, you can find the installation manuals at the manufacturers website. For instance, here is where you can find Whirlpools WDF530PLYM installation manual.
2. The reason to download and read through the installation manual before getting your dishwasher, is that you will want to read the Installation requirements needed to install the new dishwasher and find the parts that DO NOT come with your dishwasher, but are needed in order to install the new dishwasher.  You'll also want to see if there are any tools that you might need to make the installation quick and easy.  Reading through the installation manual first, will help save countless trips to the hardware store.
3. For the WDF530PLYM dishwasher and probably most new dishwashers, you DO need to buy seperately a 3/8" Compression x 3/4" hose fitting (Whirlpool 3/4" Swivel Gooseneck Hose Fitting), which surprisingly does not come with the new dishwasher, in order to attach a water line to the dishwasher.  You may also need to buy a new water line.  In my case, the old dishwasher that was installed had a copper tube for the water line, and before the new installation I thought I could reuse it without having to buy a new flexible water line or adjust the copper tubing.  However, I discovered that the compression fitting on the copper line would not fit on the 3/8" Compr. x 3/4" hose fitting. Considering that copper tubing is a pain to work with, I decided to just buy a flexible water line.
4. But because I didn't read the installation manual before getting my dishwasher, I had already went ahead and blindly purchased a Whirlpool Dishwasher Installation Kit at when I bought the new dishwasher that does include a flexible water line, but I soon realized once I started installing the dishwasher that it didn't have all the fittings I needed to connect the flexible water line to the water line underneath my sink.  After starting to install my dishwasher and realizing I needed it, I purchased the required Whirlpool 3/4" Swivel Gooseneck Hose Fitting thinking this would connect to the copper tubing and/ or Whirlpool flexible water line, but quickly found out I still needed a 1/2" adapter compression fitting in order to get the water line connected properly under my sink. 
5. So I finally ended up buying the Watts D60U Universal Dishwasher Kit for only $12 and included everything I needed (flexible stainless steel hose, 3/4" FGH hose fitting, and the needed 1/2" compression fitting) and returned the overpriced Whirlpool Kit and Whirlpool Gooseneck hose fitting, saving me over $20.
6. When I installed the new Flexible water line, I did not use any compression (teflon) PTFE tape or any sealant. I just hand tightened the rubber compression fittings and then screwed them down just enough so they were snug.  DO NOT over tighten a compression fitting or else it will fail.  As long as, you tighten the compression fittings correctly you should not need to use any sealant (but keep in mind I'm not a plumber).  I think some plumbers will use sealant and some don't.  I believe the sealant is used more to help make the fitting unscrew easier if you need to take it off later.

Once you have all the correct fittings, hose(s) and tools, installing a new dishwasher in place of an old dishwasher is pretty straightforward if you follow the installation manual. Just be sure you do the following:

1. Make sure you Turn OFF the water supply to your dishwasher under the sink (and it can't hurt to turn off your main water line to your house as well just to be safe). 
2. Make sure you Turn OFF the electric to your dishwasher and any surrounding outlets. Be sure the electric is completely off.
3. Then just use your dishwaher's installation instructions to install your dishwasher.

Once you have everything installed and the dishwasher is running properly make sure you check for any possible water leaks.

Lastly, just for reference here's how to attach the mounting bracket to the top of the dishwaser (It was unclear to me in the installation manual, as to how they attached. It's pretty simple once you see how in the video).
