Installation Of Dishwashers

The dishwasher is fast becoming one of Australia's most essential kitchen appliances. In fact, it is now the most common 'chore-aiding' home appliance after washing machines. Research shows that nearly half of all Australian homes now have the appliance.

Also, over half a million dishwashers have been installed annually across the country in the last five years. This figure is predicted to rise by 200,000 in the next four years. Washing by hand is fast declining; more homes are choosing to install a dishwasher now that they are easily available.

This article will examine the overall cost implication of installing a dishwasher, a few tips, and the installation process. So, how much does it cost to install a new one or replace an existing dishwasher, and what factors determine the costs? Uncover the answers to these questions and so much more in the sections that follow.

Cost Of Installing A Dishwasher

Many factors influence how much you can pay to get a dishwasher installed. However, the most crucial consideration is whether you are installing a new dishwasher or replacing an old one. It is usually less expensive to replace an old dishwasher than to install a new one.

A new dishwasher installation is more expensive since it requires some preliminary work, such as remodelling your kitchen. You may also need to engage a plumber and an electrician to work on drainpipes and power outlets.

On average, a basic installation will cost around AUD 150, while that of a semi-integrated dishwasher may cost around AUD 180. The following is a breakdown of typical dishwasher installation costs:

Installation of the dishwasher

Hiring a plumber to install a new dishwasher costs between AUD 100 and AUD 150 per hour.

Installation of pipes

When you hire a plumber, you will pay according to the length of the installation and the cost of the pipes that will be installed. The price ranges from AUD 500 to AUD 1500 but could be more depending on the type of material installed and shipment to your area.

Installation of power units

An electrician will charge between AUD 150 and AUD 200 to install a power socket. Simple installs take roughly 20 minutes, while more complex ones might take up to an hour. Some electricians demand a call-out fee ranging from AUD 60 to AUD 100. As a result, before choosing an electrician, find out the rate.

Installation of a dishwasher cabinet

Here, there are two options; either hire a cabinet maker to build a custom cabinet for you or buy a pre-made one. Generally, installing a custom-built cabinet is more expensive than buying pre-made cabinets. It is not guaranteed to find cabinets that fit your kitchen. However, this should not worry you too much. Dishwasher cabinets are not too expensive to build from scratch.

Cost Of Replacing An Existing Dishwasher

You can replace an old or existing dishwasher on your own. However, to ensure that nothing goes wrong, it is best to engage a professional. Replacing an existing dishwasher will take about 30 minutes to an hour, and hiring a plumber for an hour will cost between AUD 100 and AUD 150. You may also be required to pay an additional call-out fee of between AUD 60 and AUD 100.

Cost Of Installing A New Kitchen

If you have to remodel your kitchen to install a dishwasher, you could opt for a flatpack kitchen, which is less expensive but may require you to hire an expert or learn how to install them yourself. You may also need to engage specialists to install your benchtop and electricians and plumbers to fit power points, sinks, taps, and pipes.

This might seem expensive, but it is still cheaper than a custom-installed kitchen's second alternative. Flatpack kitchens cost between AUD 3000 and AUD 15,000, while a custom-installed kitchen might set you back at least AUD 35,000.

Factors Influencing Dishwasher Installation Costs

Hiring a professional to install a dishwasher typically costs between AUD 150 and AUD 300. Other factors, however, might have an impact on pricing. For example, if your kitchen lacks a hook-up, you will need to have one installed. A hook-up might cost anything from AUD 800 and AUD 2,000. Other factors that might affect the cost of installing a dishwasher include:

Hired Professional

Hiring a certified professional to install your dishwasher might be more expensive than doing it yourself. However, installing the dishwasher yourself is not recommended, especially if it is new. You might not do it properly, causing many problems for your water systems, such as leaking or a blocked drain. The best practice is to employ a professional who has the skill, experience, and tools to install it properly and get the job done quickly.

Dishwasher Size

You should expect to pay anywhere from a few hundred Australian dollars to several thousand dollars for your dishwasher installation, depending on the job's complexity. You must accurately measure the dishwasher's dimensions because even a 0.6 cm inaccuracy might increase installation expenses.

The following are installation cost estimates for dishwashers according to size:

  • Small size: The smallest dishwashers on the market today can fit directly on the surface of your kitchen counter. Because they're only about half the average size of a washer, they can help you reduce your installation expense. They're great if you're moving or have a tiny kitchen. However, they can't clean many dishes at once due to their small size. Installation cost ranges between AUD 450 and AUD 550.
  • Slim size: A slim-sized dishwasher is excellent for small spaces or families. You can also find many of the features and benefits of a traditional-sized model in this variety. However, because it is modest in size, it cannot hold that many dishes at once. On the plus side, their water and energy usage is lower than that of the small-sized model. Installing this model of dishwasher costs between AUD 450 and AUD 1,600.
  • Standard size: It is the most popular size found in most Australian households today. There is enough space for a complete table setting for up to 12 individuals. Many feature movable legs that allow them to suit different cabinets and surface heights. You could even slot it in where your washing machine used to be. Expect to pay anywhere between AUD 450 and AUD 2,000 for a standard-sized space.
  • Extra-sized: An extra-sized dishwasher is an excellent choice for a large household. They have nearly the exact same dimensions as the standard version above, except that their interior is much more spacious. They feature two light motors instead of one big one, which frees up space and makes it easy to move around. However, they are challenging to install because of their sophisticated design. This machine can wash up to 16 dishes at a time. Its installation cost is between AUD 550 and AUD 2,200.

Dishwasher Type

Different models of dishwashers have their unique installation processes, and this has implications on the installation cost. The following are some common types of dishwashers and their installation costs.

  • Built-in dishwasher: This is the most popular type of dishwasher. It comes with two racks and measures about 61 cm in width (some smaller versions are 48 cm wide). It requires a professional to install one, and it will cost you between AUD 350 and AUD 1,300.
  • Drawer dishwasher: The drawer dishwasher is best for small kitchens because it can easily fit into cabinets. This type has only one rack. It is an ideal pick for individuals who don't do a lot of dishes. Installing this dishwasher will cost you between AUD 300 and AUD 500.
  • Countertop dishwashers: This is a simple dishwasher that you can install on a countertop as you would a microwave. It is ideal for a kitchen that lacks a built-in dishwasher space. The dishwasher is relatively inexpensive but can only handle a few dishes at a time. With this dishwasher, no plumbing work is required, which means you won't need to change your hot water systems. After reading the installation manual, you should be able to set it up yourself. Installing one will cost you between AUD 240 and AUD 360.
  • Portable dishwashers are about the same size as built-in dishwashers, which makes them a fantastic solution for kitchens that don't have a designated space for dishwashers. You can also store them in a utility closet. There is no plumbing needed, so your water system remains the same. You just connect yours to a kitchen sink. They are simple to install, and you can do it yourself or hire a professional, which will cost between AUD 480 and AUD 800.

Kitchen Finishing

Choosing the best finish for your kitchen is critical to enhancing the room's look and feel. The following are some popular finishing options for your dishwasher installation.

  • Bisque: This finish has a slight orange undertone that distinguishes it from other white paint hues. Meaning it mixes well with the rest of your space. If you choose bisque, match the rest of your appliances because different tones of the same hue can seem chaotic. Dishwasher installation costs range from AUD 360 to AUD 720 with this finish.
  • Black stainless steel: Clean-up is a breeze with this finish. It's also less likely to get fingerprints on it. They make your space look stylish and sleek. This type of dishwasher will cost between AUD 800 and AUD 2500.
  • Slate: Slate looks like the perfect combination. It resembles natural stone, making it less monochromatic than stainless steel. It can give your kitchen a somewhat more welcoming feel, but it's easy to make it look out of place with more contemporary cabinetry. Installation expenses for a dishwasher with a slate finish range from AUD 700 to AUD 1,250.
  • White: The colour white is a timeless classic that will never go out of style. You can choose from various designs and sizes to fit your needs. The downside is that a yellowish shade may emerge over time, making your area appear shabby. A white finish will cost you anywhere from AUD 500 to AUD 1,600.

Process Involved In Dishwasher Installation

Step One: Gather your equipment and tools

Gather all the equipment and tools and keep them near the installation site for easy access. You will need the following:

  • Duct tape(optional)
  • A brass fitting
  • Braided steel water line.
  • A pair of rubber hand gloves (optional)
  • Wire nuts
  • Teflon tape
  • A screwdriver
  • A hose clamp
  • A pair of pliers
  • An adjustable wrench
  • A drill

Step Two: Take the necessary safety measures

Firstly, turn off the power at the circuit breaker and unplug the electrical cord if it is a plug-in dishwasher. Next, switch off the hot water shut-off valve beneath the kitchen sink. Now run the tap to ensure the water supply is turned off.

Step Three: Unhook and remove the old dishwasher

This step only applies if your kitchen has an old dishwasher that you want to replace. Skip this if you do not have an existing dishwasher. To begin, proceed to remove the cabinet door to access the old dishwasher. Now, remove the access panel cover located at the bottom front side of the dishwasher.

Locate the junction box inside the access panel. Next, unscrew the terminal screws keeping the wires in place at the junction box. Then, remove and gently tuck the wires out of the way with duct tape. Additionally, you will need to locate the dishwasher water inlet tube, undo the brass fitting and disconnect the water supply pipe from it.

You can now put the disconnected end of the water supply line pipe into a bucket or bowl to drain any remaining water. Once this is done, you can then reach beneath the sink to disconnect the drain hose. Loosen, then clamp and take off the drain hose of the dishwasher from the sink's tailpiece.

Next, put the disconnected end of the drain hose into a bucket to collect the water and waste. Once the water has sufficiently drained, you can remove the screws holding the dishwasher in place with a screwdriver, gently pull the dishwasher out from the cabinet and set it aside.

Step Four: Install the new dishwasher unit

Place your new dishwasher unit close to the area where you will carry out the installation. Remove it from its packaging and go through the user manual.

Connect the water supply line

Wrap Teflon tape securely around the tip of the water inlet pipe located at the base of the dishwasher. Screw on the 90-degree brass fitting to the taped inlet pipe and secure it with an adjustable wrench.

Note: Most dishwasher units do not include a brass fitting, but they are available at hardware stores.

Once you have the fitting, connect the new water supply line to the elbow of the brass fitting. Pass the other end of the waterline through one of the cabinet holes and place it on the floor beneath the kitchen sink.

Connect the drain line

Locate the dishwasher drain standout pipe and connect the drain line to the dishwasher before securing the connection with a hose clamp. Pass the other end of the drain line through the cabinet hole and place it towards the sink drain tailpiece.

Slide the dishwasher into its designated place

Attach the adjustable legs to the base of the dishwasher. Next, carefully slide the dishwasher beneath the countertop into the cabinet. Stop halfway to ensure everything is in a good position before sliding it in completely. Finish hooking up the water line by connecting the other end to the dual shut-off valve found beneath the kitchen sink.

You can now proceed to connect the drain hose through an air gap to your garbage disposer, if you have one, or to the drain tailpiece of your sink. If you don't have an air gap, form a high loop with the drain hose prior to connecting it to the garbage disposal or the sink drain tailpiece.

Hook up the electrical wires

First, remove the cover of the access panel and unscrew the cover plate of the junction box. Next, connect the circuit breaker's wire to the junction box's wire. Following this, connect the white wire to the white wire, the black to black, and the green to ground wire at the junction box.

Use wire nuts to secure the connection tightly in the junction box. Place the cover plate back and screw it back onto the junction box and close the access panel. Skip this step if your new dishwasher has a power cord wired to it at the manufacturing factory.

Step Five: Finish the installation

  • Give the dishwasher a test run to see if it is working correctly.
  • Keep an eye out for water leaks at the water lines and drain line. In addition, check for leaks around the dishwasher.
  • Screw the metal brackets to the underside of the countertop with a screwdriver. Doing this will keep the dishwasher in place and prevent it from tipping forward.
  • Finally, pack up your tools and clean up the floor.

Tips For Installing A Dishwasher

Installing or replacing a dishwasher is a delicate task that you should handle with all forms of care, and that is why you need the services of a professional to assist you. However, it is not impossible to handle the installation yourself. If you decide to do the installation to maybe save some money, you need to take note of the following:

  • Read the installation manual carefully and make sure you understand every step before beginning. If you are unsure of what to do at any stage, speak to a professional before you proceed with the installation.
  • Consult someone more knowledgeable than you about installing your specific type of dishwasher. There might be a slight variation in the installation process of your particular model.
  • Instead of nails, use cable ties to secure your shelving units to the walls. Cable ties provide stability and protect the machine from damage.
  • Remove dust carefully using gloves as finger oils can cause lime scaling, making future repairs difficult. If you are replacing a pre-existing dishwasher, check that the water (cold and hot water system) and power supply connections are in the proper location.
  • For first-time installations, you need to make holes in the cabinet for the water supply, the electrical wiring, and the drain hose. The dimensions of the hole and where to drill will be specified in your manual.
  • If your countertops are made of wood, apply moisture barrier tape on the sides along the front edge of the counter.
  • Your dishwasher should have a dedicated circuit. You should connect other appliances to the circuit.
  • Confirm that there are no blocked drains, and if there are, make sure you unblock them before installing the new dishwasher.
  • Follow standard safety practices when connecting the dishwasher's cold-water supply line to that of the home's hot water heater.

Hire A Reputable Plumbing Company

Although you may be tempted to install a dishwasher yourself to save money, hiring a professional to handle the installation is best. A professional will guide you through the costing, material selection, and aesthetic considerations. These three steps require extensive skills that you may not have, which may affect the planning and installation of your kitchen appliance.

So, next time you decide to conduct an installation of a dishwasher in your home, office, or restaurant, make sure you hire a reputable plumbing company with the skills, experience, and tools to do the job!
