How much does dishwasher installation cost?

Depending on the service you choose and the type of dishwasher you have, installing a dishwasher may cost $149 for a simple installation to $176 for a fully or semi-integrated dishwasher. Some services offer lower rates, so shop around before you hire an installer.

If you hire a plumber to install a dishwasher, it may or may not cost more. Plumbers generally charge between $100 and $150 per hour and if they are replacing an old dishwasher, they may charge a call-out rate of $60 to $100. It doesn't take long to install a dishwasher. It may take the plumber 20 minutes to an hour to install it. If it takes 20 minutes, they will charge in 15 minute increments, so their cost may not be higher, but it will depend on their call-out rate.

If you are installing a new dishwasher, there are many costs involved:

  • A plumber will have to install pipes
  • An electrician will need to install a power point
  • You may need to install a dishwasher cabinet
  • If you're replacing a cabinet with a dishwasher cabinet, you may need to find a place for the other cabinet if you use it often
  • You may need to have a new kitchen installed

The plumber will charge by the number of hours they have to work and the cost of the pipes will also be included in the final price. The cost may be between $500 and $1500 or more depending on how much piping they need to install and other costs.

An electrician can install a power point from between $140 and $180 depending on how much work they have to do. $140 is for a simple installation that takes only 20 minutes and $180 is for a more complicated installation that takes over an hour. On average, electricians charge around $150 to install a power point, but some electricians also charge call-out or service rates for simple jobs. A call-out rate can be between $60 and $100, so to find a lower rate, get quotes from electricians for the installation of a power point.

If you can find a flat pack dishwasher cabinet that matches your kitchen, it will cost less than having a dishwasher cabinet built and installed for you by a cabinet maker. However, you may not be able to find an exact match to your kitchen and will need to get quotes from cabinet makers for the cost of building a dishwasher cabinet. A dishwasher cabinet won't be too expensive, but the cabinet maker will need to take careful measurements for a built-in dishwasher and will take longer to install it.

If you’re having a kitchen renovation, you have two choices. Flat pack kitchens are far less expensive than kitchen renovations, but you will have to install a flat pack kitchen yourself or hire a handyman to install it for you. You will also need to have the benchtop professionally installed because all kitchens are not square and installers know how to install them seamlessly. You may also need to hire an electrician to install a power point and a plumber to install pipes, a sink and taps. Even with those additional expenses, you will still save, since flatpack kitchens cost between $2600 and $12,000 and a custom installed kitchen can cost $35,000 or more.

How to purchase a dishwasher

Before you have a dishwasher installed, you need to purchase a dishwasher. Some things to consider when purchasing a dishwasher are the Star rating and WELS rating of the dishwasher.

A good dishwasher will have adjustable shelves, a large spray head for cleaning pots and pans and a good drying function. Some drying functions include:

  • Residual heat drying is energy efficient, but may not dry your dishes completely
  • Fan and heat assisted drying is less energy efficient, but will dry your dishes
  • Zeolite uses crystals to absorb moisture and heating to dry dishes. These dishwashers tend to cost more than other dishwashers

The Star rating on a dishwasher is important. The more stars a dishwasher has, the more energy efficient it is. The WELS rating is a measurement of water consumption. A higher WELS rating means a dishwasher uses less water to get the job done, but less water doesn't mean a dishwasher will be less efficient. The water may come out at higher pressure to wash dishes.

Some other things to look for in a dishwasher may include:

  • Flood protection detects water at the base of the dishwasher and will shut off the dishwasher if it detects a problem
  • Sensor wash dishwashers can sense how dirty dishes are and make temperature adjustments depending on how dirty dishes are
  • A WiFi enabled dishwasher allows you to turn it on from a distance using a smartphone
  • Some dishwashers allow you to install a panel that matches your kitchen design.

These extra features will cost more, but you may want to have them. The most important things to look for are the Star rating and the WELS rating because they will save you money over time.

Dishwashers cost money and some dishwashers cost more than others. Rather than buy a cheap dishwasher, look at the length of the warranty and the quality of the machine. A more expensive dishwasher may serve you better than a cheap dishwasher. A moderately priced dishwasher may cost around $1000 and some of them are as good as more expensive dishwashers.

You can also purchase drawer dishwashers and slimline dishwashers. Drawer dishwashers are smaller than normal dishwashers and you have to open a drawer to access the dishwasher. A slimline dishwasher may be a good choice if you have to alter or replace a cabinet. It will take up less space and you may have space left over for another cabinet.

How to install a dishwasher

Installing a dishwasher can be a DIY job, but it is always best to hire a professional plumber or handyman to install a dishwasher for you, to avoid any plumbing issues. Dishwashers can cause issues in the long run when they are not installed properly.

It’s also worth noting that newer dishwasher models come with a water flow sense meter as a safety device. This is pretty big and bulky and won’t fit in small holes that may have been installed in cupboards for older models. If you’re not handy, you might want to hire a tradie for this one.

Q: I live in a 1940s house with a kitchen that has never been updated. I’m tired of doing the dishes by hand and would really like to get a dishwasher. I don’t have a garbage disposal and don’t really want or need one. I compost all my organic food waste.

Is it possible to get a dishwasher or am I doomed to continue with washing dishes by hand. Do I have to spend big bucks to have the kitchen remodeled? I’m pretty handy so if possible I’d like to do this myself using the existing kitchen cabinets.

The counters are 25 inches deep with tile countertops, and the counter height is 35 inches. There are two side-by-side banks of drawers to one side of the sink measuring 26 inches between the stiles. This seems to be a perfect place for a dishwasher. What do you think?

A: Yes, you can have a dishwasher in your kitchen. Furthermore, you can do most of the work yourself and save a bunch of money. Four things are necessary for a built-in dishwasher: a place for it; a water supply line; a drain line; and power. We’ll take these in order.

Cabinet space: Standard under-counter dishwashers are 24 inches wide, 24 inches deep and approximately 35 inches high with adjustable legs. We’ve installed a dishwasher in an opening a little less than 34 inches tall. Based on your description, it sounds as if it’ll be a tight fit, but a fit nonetheless. There are narrower models and also single-drawer models with different dimensions available if the standard size won’t work. We’re sure that with a little research you can find one that will fit your space.

The drawer banks are an ideal location. It’s best to locate a dishwasher close to the sink for easy access to water and waste lines. Often 1940s vintage cabinets were built in place. Getting your opening should be as easy as removing the drawers, cutting out the cross rails and cutting out the bottom of the cabinet with a reciprocating saw.

Water supply: A dishwasher needs hot water. The closest source is the hot water supply under the sink. Replace the shutoff valve with a new one that connects both the sink and the dishwasher to the hot water line. The new valve, also known as an angle stop, will have a vertical outlet to be connected to the faucet and a horizontal outlet to supply hot water to the dishwasher. Use a long braided wire hose available at plumbing supply houses, hardware stores and home centers for the connection. You may need to drill a hole in the side of the cabinet to route the hose from the shutoff valve to the dishwasher opening.

Drain line: The dishwasher will come with a hose used to connect the dishwasher to the drain under the sink. Normally the hose is connected to an inlet in the garbage disposal. Because you don’t have one and don’t want one a little simple plumbing is in order. Water empties from the sink, through a strainer, into a tailpiece connected to a p-trap and then into the waste line. To connect the drain hose replace the straight tailpiece you have now with a tailpiece that looks like a “Y.” Secure the drainage hose to the “Y” with a hose clamp.

Depending on the local plumbing code, you may have to install an air gap in the countertop. This will entail cutting a hole in the tile with a diamond-tipped hole saw attached to a drill. An air gap is a backflow preventer, keeping dirty water from re-entering the dishwasher. If an air gap is not required, the same thing can be accomplished by securing the drain line with a clamp at the top of the sink cabinet.

Here’s a YouTube video on drain lines and air gaps that we think is worth watching: http://www.youtube.com/watch?v=t7dEkdHjR84.

Power: Local codes usually require a dishwasher to be on a separate circuit that may be shared with a garbage disposal. The size of the wire and the circuit breaker will depend on the load the dishwasher draws. To be safe, we use 12-gauge wire run to a duplex plug and protected by a 20-amp circuit breaker. If the electrical box is surface-mounted, use armored cable to run the line. This is the only part of the job that may not be appropriate for your do-it-yourself project. It depends on your experience and your level of comfort working with electrical wiring.

With the water, drainage and electrical in place, read the dishwasher manual for hookup instructions. In any case, because there is some question as to whether an air gap is required and there is new wiring involved, get a permit and have the job inspected.
