How To Install a Dishwasher Safely at Home

A dishwasher is an excellent investment in everyone's day-to-day life for home improvement. It offers an efficient, reliable and smooth partner through those crazy work weeks or weekends. The large-capacity and programmable dishwasher can make quite the difference in managing a home.

They come in an array including portable, energy-efficient and built-in dishwashers. Purchasing a new dishwasher from a speciality outlet gives you the option of having the delivery team set it all up for you, and it may also include hailing away your old one.

However, if you purchase it online or from a general home appliances store, setting it up is not usually included. In this case, it might cost you an additional fee to have it done. For the most part, installing a new one is such an uncomplicated process that it could take a few hours and the use of some essential tools.

Once unboxed, you'll find a dishwasher installation manual on installing a new dishwasher in the dishwasher sink cabinet in your kitchen. If you have an old dishwasher, you'll need to remove it first to hook up the new dishwasher. Prior dishwasher owners don't have to go through the mystery of trying to figure out where best to install the new dishwasher or how to install a dishwasher.

Here is a simple Do-It-Yourself project guide that DIYers can follow if they know and understand what is required. You'll need these tools:

  • Screwdriver and a driver drill
  • Adjustable wrench
  • A drop sheet of cardboard (optional)
  • Hose clamp
  • Tape
  • A mop and bucket
  • The inlet and outlet hoses that came with your dishwasher and the mounting hardware included

Guide on Installing a Dishwasher

1. Replace the Old Dishwasher and Install a New Dishwasher

After you've measured that your new dishwasher fits in the cabinet space under your kitchen, replacing an old one is relatively easy. With the power cord, water supply pipe line, drain line and play in place, you need to slide the dishwasher out. Follow the instructions to connect the new one to the drain having connected to the inlet tap, then plug it in, and your dishwasher is good to go.

2. The 3 Mechanical Connections

Three connections make up a dishwasher installation: the power-cord connection, a water supply line connection, and a dishwasher drain line. As a DIYer, this little project is manageable if you understand what is required, especially in step 1. 

a) Power cord connection: If you don't have electrical wiring experience, it might be the most sensitive. You can 'hard wire' the dishwasher with an NM circuit cable that goes directly into the wire connection box on the dishwasher.

Alternatively, use a standard appliance cord plugged into a wall outlet. Make sure the dishwasher has a dedicated circuit for a complete electrical code supply line.

If yours doesn't include this, make sure to have a new power cord installed before installing a dishwasher.

The latter is a better strategy since it's easier to disconnect for servicing in the future. Both hard-wired connections and appliance cord connections have the same installation process, but wire connections are produced inside an access panel at the appliance base.

b) The water-supply valve connection - involves connecting the end of the water supply line tube to the inlet valve of the dishwasher and the other end to a shutoff valve on the hot water supply line pipe for water line installation.

This water supply tube hooks up to the dishwasher require fixing a dishwasher 90. This brass elbow fitting allows the supply valve to connect to the dishwasher easily. It's through the holes in the sidewall of the cabinet that you can do this.

c) Connect the drain tube hose- The dishwasher drain hose connects to the sink drain cabinets under your kitchen sink. The drain hose is plugged into the countertop's underside under the house sink to pass dirty water and food waste.

The proper method of doing this depends on the local codes in your area. As the drain hose loops back down, it is attached to a little part on the garbage disposal or directly to the sink drain tailpiece.

3. Position the Dishwasher

Turn the dishwasher the right side up and then slide it into place. Through the holes in the cabinet's sidewall, you can feed the cord, the water supply tube, and the drain hose. Line the appliance up to the centre of the opening without pushing it too far back.

4. Attach the Electric Cord

Most electrical hookups and plumbing connections are behind the access panel, which is mounted on the dishwasher's front bottom. The easiest way is to carefully lay the dishwasher on its back to check on the access panel and make the preliminary connections.

First, remove the bottom access panel on the dishwasher. Then identify the power connection fittings, the water inlet solenoid valve, and the drain fitting. 

5. Anchor the Dishwasher

After the placement of the dishwasher, fasten everything into place. Open the dishwasher door to access the mounting brackets. Use the screws provided and a power drill to attach the brackets to the cabinet frame under the lip of the counter.

6. Test the Dishwasher

Plug in the dishwasher’s electric cord. By running the dishwasher through a full cycle, you can test whether it can drain water out properly. And it has no leaks at any of the connections in the sink cabinet before putting the face-plate on the front of the dishwasher opening.

7.Put the Face-plate

The last step involves putting the face-plate back on the bottom front of the dishwasher.

Frequently Asked Questions on How to Install a Dishwasher

1. How does it work?

Through water fills and drains, dishwashers clean your dishes by spraying them with hot water and dish detergent through water fills, followed by drying. They may differ in size, shape, and placement.

Then using the drain trap, move soil and food residues, and then rinse your dishes clean. A cycle heats your plates so they dry more quickly and with less water spotting.

2. What is the correct way of loading dishes?

Every dishwasher is different, but the general principles of loading a dishwasher are typically the same. Face dishes inwards towards the centre of your machine.

3. Are there items I should not place in it?

Leave out the wood, iron, aluminium, crystal plates. There is a manufacturer’s recommendation on what is dishwasher-safe. Silver and steel can be placed in the dishwasher but do not put them in the same compartment with rest since it will lead to tarnishing.
