Dishwasher Installation Sydney

Installing a dishwasher seems simple, but if you want to do it yourself, you must have some plumbing knowledge to avoid problems. It’s better to seek professional help as these problems could harm your home and/or kitchen.

Installing a dishwasher in Sydney might raise a common question: How much does it cost to install a dishwasher? This is because you will have to bear a high cost for dishwasher installation if you choose the wrong plumber. Therefore, knowing the cost of installing a dishwasher in Sydney is crucial.

Simple dishwasher installations are cheap. You might spend $500 or less. For more complex installations, prices rise above $5000.

In this blog, we’ll take you through the prices of dishwashers, do-it-yourself installations, and how to know if you need a new installation.

The Types of Dishwashers

Types of Dishwasher

Here are the different types of dishwashers you can purchase:

1. Freestanding Dishwasher

$400 to $2000

Freestanding washers are connected to your kitchen tap and drain into your sink.

2. Benchtop Dishwasher

$250 to $1000

These are dishwashers installed on the counter.

3. Built-In Dishwasher


This dishwasher is installed under your kitchen countertops and is connected to your home’s plumbing.

4. Semi-Integrated Dishwasher


These are dishwashers with an exposed control panel, unlike fully integrated dishwashers.

5. Fully-integrated Dishwasher 


This type of dishwasher is installed behind a cabinet. They blend seamlessly into your kitchen layout.

Signs Your Dishwasher Needs Replacing

Signs Your Dishwasher Needs Replacing

Do you need a plumber to install a dishwasher or not? Here are signs indicating whether your dishwasher needs a replacement:

  • Age: Experts recommend replacing if your dishwasher is 10 years or older. Also, outdated appliances are inefficient and tend to clog up your pipes.
  • Rust: A small rust spot here and there isn’t a cause for alarm. However, when you see rust inside your dishwasher, it’s time to install a new one. Rust can contaminate your dishes and lead to water leakage.
  • Water Retention: When your dishwasher pools at the bottom, you need to replace it. It means there’s a drain issue.
  • Broken Latch: A broken lock prevents a dishwasher from cleaning utensils. Before you buy a replacement, check whether repairs are possible.
  • Cracks: Whether through wear and tear or damage from a utensil, a cracked dishwasher leads to water damage.
  • Dishes Remain Dirty: Your dishwasher needs replacement if your dishes remain dirty after ruling out soap, incorrect dish placement, and caked-on food.

How to Install a Dishwasher: DIY

How to Install a Dishwasher

If you know how to install a dishwasher yourself, you will no longer be asked, “Do you need a plumber to install your dishwasher”.

Here’s how you can install your dishwasher:

  1. Check your new dishwasher. It should have no scratches or dents, and check that it came with a warranty and manual.
  2. Turn off the water supply and electricity in the room.
  3. Cover the floor with a cover sheet. This is to protect your floor and to make clean-up easier.
  4. If you already have a dishwasher, turn it off and disconnect its water hose, electrical head, and waste hose. Now, remove it.
  5. Clean where you plan to put the new dishwasher.
  6. Put the dishwasher close to where it will go. You need some space to connect it again, but the cable and hoses should have some slack.
  7. Once it’s in place, reconnect the water and electricity supply. Tip: Hand-tighten the water hose to the isolation valve.
  8. Connect the waste hose. Loop the waste hose in an upside-down ‘U’ to avoid siphonage. Hang the waste hose high and clamp it in place with the clamper provided with the dishwasher.
  9. Slide the dishwasher in its final position.
  10. Turn on the water and electricity.
  11. Run a full cycle and observe the machine. In particular, watch out for leaks.
