How to instal washing machine: How to Install Washing Machine: Step-by-Step Guid
Thinking about installing a new washing machine yourself? It might seem straightforward (unplug the old one, plug in the new one), but a bit of prep work is what separates a smooth job from a weekend-long headache.

Getting it right from the start is the key to preventing leaks, floor damage, and performance issues later on.
Your Pre-Installation Game Plan
Before you even touch a tool, a solid plan is your best mate. We’ve seen countless DIY jobs go sideways because of a few simple missed steps. This checklist will help you avoid the common pitfalls we see out in the field.
First up, get out the tape measure. It sounds basic, but you’d be surprised how many people just measure the machine's footprint. You need at least 100mm of clearance behind it for the hoses and some breathing room for ventilation. Also, leave about 25mm on each side to stop the machine from rattling against walls or cupboards during a spin cycle. And, of course, make sure you can still open the laundry door!
Inspect Your Connections And Tools
Once you’ve confirmed the machine will fit, have a good look at your plumbing and power points. Can you turn the hot and cold water taps on and off easily? If they’re seized, rusted, or look heavily corroded, that’s a big red flag.
Check that your power point is a proper three-prong, earthed socket, and that it’s close enough. Never, ever use an extension cord. It’s a major fire hazard and simply not worth the risk.
Getting your tools together now saves a frustrating mid-job run to the hardware store. Here’s a quick list of what you'll need.
Essential Tools and Materials for Installation
| Item | Purpose | Pro Tip |
|---|---|---|
| Adjustable Wrench or Pliers | For tightening hose connections. | A quality wrench gives you better grip and less chance of stripping the plastic fittings. |
| Spirit Level | To make sure the machine is perfectly balanced. | A wobbly machine is a noisy machine. This is non-negotiable. |
| Bucket & Old Towels | To catch water from the old machine's hoses. | There’s always more water left in the hoses than you think. Have them ready! |
| Tape Measure | To confirm all your clearance measurements. | Measure twice, move the machine once. |
This small toolkit will handle most standard installations and keep you from getting stuck.
A common mistake we see in Sydney is people overlooking their home's water pressure. An installation that doesn't account for pressure can lead to burst hoses and serious water damage, a frequent call-out for us, especially in older homes around the North Shore.
High or fluctuating water pressure is a hidden enemy of appliance hoses. If you've had issues with pressure before, it’s worth understanding the risks of a burst water pipe and what to do. A simple pressure gauge can tell you if you're within Australian Standards, potentially saving you from a very costly and wet disaster.
Removing Your Old Washing Machine
Before you can welcome that shiny new washing machine, the old one has to go. And trust me, getting it out without a flood or a pulled muscle is half the battle. A bit of prep here goes a long, long way.
First, and I can't stress this enough, kill the power. Unplug the machine from the wall socket. No excuses. With that done, you'll need to shut off the water supply. Look for the two taps on the wall behind the machine, usually with red and blue indicators for hot and cold. Turn them clockwise until they're firmly off.
Now for the messy bit. There's always water left in the hoses, so grab a bucket and a few old towels before you start unscrewing anything. Position your bucket and slowly loosen the inlet hoses from both the wall taps and the back of the machine. Don’t be surprised by a bit of spillage. It’s totally normal.
Disconnecting and Draining
Next up is the drain hose. Gently pull it from the laundry sink or the standpipe it feeds into. Make sure to tip the end straight into your bucket to catch all that murky, leftover water. If you notice the water is draining really slowly or see a lot of sludge, it could be a clue that you've got a bigger blockage brewing in your pipes. It's something we see all the time; a professional drain camera inspection is the only way to know for sure what’s happening down there.
With all the hoses disconnected, you're ready for the big move. These things are surprisingly heavy and always awkward to wrestle with.
It’s worth taking a moment to learn how to safely move heavy furniture and appliances. A dolly or even just some appliance sliders can be a lifesaver, and so can a second pair of hands. Your back will thank you!
Once the old workhorse is out of the way, do yourself a favour and have a good clean-up. Get rid of the dust bunnies, lint, and any water spills. Starting the installation in a clean, dry space makes everything easier and stops you from trapping moisture and grime behind your brand-new appliance.

Making Secure Water and Drain Connections
Alright, with the old machine out of the way and the area cleaned up, you’re now at the most critical part of the job. This is where the magic happens. Getting the water and drain connections right is the difference between a perfectly running new appliance and a laundry room flood. Trust me, you want to get this right the first time.
Before you even think about connecting your shiny new machine, you need to flush the water lines. It's a simple step, but one we see DIYers skip all the time. Just grab a bucket, hold it under the hot and cold taps, and let them run for about 30 seconds. This clears out any gunk, rust, or sediment that’s been sitting in the pipes. If you don't, all that debris will head straight for your new machine's filters, causing blockages from day one.
Starting with clean lines sets you up for success. Now, let’s get those connections sorted.
Securing the Inlet Hoses
Your new washing machine came with new inlet hoses for a reason. Use them! It’s tempting to reuse the old ones if they look okay, but don't. The rubber washers inside have already been compressed and simply won't create a perfect, watertight seal a second time around. It's a leak waiting to happen.
First, connect the hoses to the back of the machine. It’s usually easier to do this before you push it fully into place. Match hot to hot (red) and cold to cold (blue). Just get them hand-tight for now. Then, connect the other ends to your wall taps.
Now it's time to tighten them properly. Using multigrips or an adjustable wrench, give each connection a gentle quarter-turn past hand-tight. That's it. One of the most common mistakes we see is overtightening, which can crack the plastic fittings or split the washer, causing the very leak you're trying to prevent.
Our Pro Tip: Once everything's connected, turn on the taps at the wall. Run your fingers over all four connection points, two on the machine and two on the wall. Check for even the slightest hint of moisture. Catching a tiny drip now will save you from the headache of a slow leak discovered days later behind the machine.
Positioning the Drain Hose Correctly
The drain hose is just as important as the water supply. Getting this wrong is a leading cause of machine faults and, you guessed it, water damage. In fact, we see issues with drain hoses all the time on jobs across Sydney. Data from the Plumbing Industry Climate Action Centre (PICAC) showed that a staggering 37% of washing machine failures in NSW during 2024 were linked to incorrect drain setups.
The Australian Standard for plumbing is very specific about the height of the drain outlet, and for good reason. It’s all about preventing two major problems:
- Siphoning: If the hose is too low, water can get sucked out of the machine during a wash cycle. This leads to poor cleaning results and can trigger error codes.
- Backflow: If the hose isn't secured in the drain, dirty water from the sink or standpipe can flow back into your machine, contaminating a fresh load of laundry.
To do it right, the top of your drain standpipe (or the entry point to the laundry sink's trap) must be between 600mm and 900mm from the floor. Your machine should have come with a U-shaped plastic guide. Use it to hook the hose into the drain. This creates the perfect arch and holds it securely.
Finally, make sure the hose has a smooth run with no kinks or tight bends. Any restrictions can put a real strain on the machine's pump. Paying attention to these plumbing basics is key, whether you're installing an appliance or figuring out how long hot water systems typically last.
Alright, with the tricky water connections sorted, it’s time to make sure your machine is rock-solid. This is a step people often rush, and it’s a massive mistake.
An unbalanced washing machine doesn’t just make a racket; it’s literally shaking itself to pieces. Getting it perfectly level is non-negotiable if you want to avoid that awful thumping and stop it from "walking" across your laundry during a spin cycle. This one thing will drastically cut down on premature wear and tear.
First Things First: Remove the Shipping Bolts
Before you even think about levelling, you have to remove the shipping bolts. Seriously, do not skip this.
These are long bolts, usually on the back of the machine, that lock the drum in place so it doesn't get damaged during transport. Forgetting to take them out is the fastest way to destroy a brand-new appliance. The drum needs to move freely; leaving it bolted down will create catastrophic vibrations that can wreck the suspension and motor in a single wash.
Getting the Balance Just Right
With the shipping bolts out, grab your spirit level. Place it on top of the machine and check it from front-to-back, and then side-to-side. Most laundry floors, especially in older Sydney homes, are far from perfect, so expect to make a few adjustments.
Your machine will have four adjustable feet. Some you can turn by hand, others need a wrench. Here’s how we do it on the job:
- Find the Low Point: The bubble in your spirit level always drifts towards the high side. The corner opposite that is where you need to start.
- Adjust the Foot: Get a helper to tilt the machine back slightly, taking the weight off the corner you're adjusting. Turn the foot counter-clockwise to extend it and raise that corner up.
- Check and Repeat: Gently lower the machine and put the level back on top. Keep making small, patient adjustments to each foot until that bubble is dead centre, both ways.
Once you think you've got it, give the machine a firm push on each top corner. It should feel completely solid. No rocking, no wobbling, nothing. That stability is your best friend against noise and vibration.
A 2024 study from CHOICE found that a shocking 68% of washing machines that weren't properly levelled suffered from premature seal failure within just two years. Taking five minutes here really can add years to your appliance's life.
The Final Step: Power and Safety Checks
With the plumbing done and the machine perfectly stable, the very last connection is the power. This is where you need to be extra careful.
According to 2024 data from Fire & Rescue NSW, electrical faults contribute to 19% of appliance-related fire risks on the North Shore alone. Don't become a statistic.
Your machine must be plugged directly into a three-prong, grounded wall outlet. Never, ever use an extension cord. They aren't designed for the high power draw, can easily overheat, and are linked to 33% of appliance-related electrical shocks in Australia. Make sure the power point is within reach of the machine's cord, which is typically about 1.5m long.
Once it's plugged in, you’re on the home stretch. All that's left is to run a quick test cycle to make sure everything is working just as it should.
Alright, the machine is in place, but don't start throwing your laundry in just yet. The job isn’t truly done until you’ve seen it run flawlessly with your own eyes.
This last part is your quality control. A quick test cycle is the best way to spot a tiny issue before it decides to become a massive, floor-soaking headache.
What to Watch and Listen For
With everything connected, it's time for a quick, empty test run. Just choose a short program. Most modern machines have a "Quick Wash" or "Rinse and Spin" setting that's perfect for this. No need for detergent or clothes; this is all about the mechanics.
As soon as the machine starts to fill, grab a torch. This is your first chance to catch a leak. Get a good look at the inlet hose connections, both at the taps on the wall and where they connect to the back of the machine. I always run my fingers over the fittings; you're feeling for even the smallest drop of moisture. A single bead of water means the connection needs another quarter-turn.
Now, listen. A properly installed machine should be surprisingly quiet, just a steady hum. Any loud clanking, banging, or grinding sounds are red flags that something isn't right.
Keep an eye on the machine's body, too. Does it stay put?
- Excessive Shaking: If it's vibrating like a jackhammer, your first move is to re-check that it’s perfectly level. Even a slight wobble can cause a lot of movement.
- "Walking": Is the machine trying to dance its way across your laundry? This is a classic symptom. It could mean it's not level, but nine times out of ten, it's because the shipping bolts are still in.
When the cycle finishes and the water starts to drain, shift your focus to the waste hose. Water should flow out smoothly into the tub or standpipe without any nasty gurgling or backing up. Make sure the hose hasn't jiggled loose during the spin cycle.
A successful test run is your ultimate peace of mind. It’s the moment you know for sure that the hoses are tight, the drum is balanced, and the drain is clear. This is when you can confidently say the job is done right.
The Final Inspection Checklist
Once the cycle is complete and the machine powers down, it's time for one last look-over. This just ensures everything is 100% safe and ready for the family's laundry.
Final Checkpoints:
- Hose Connections: Go back and double-check all four water connection points. Dry fingers are your best tool here. Feel for any dampness.
- Machine Position: Confirm the appliance hasn't budged an inch and is still rock-solid.
- Power Cord: Make sure the cord isn't pinched, stretched tight, or kinked behind the machine.
- Clearance: Check that you've still got that essential gap around the machine for proper air circulation.
If everything on this list gets a tick, congratulations! You've successfully installed your new washing machine.
But what if you ran into a problem? If you’ve got a leak that won't quit, a noise you can't diagnose, or any other issue that’s giving you grief, don't keep struggling. Sometimes the smartest DIY move is knowing when to call in a professional. For any installation headaches in Sydney, you can always get in touch with our expert plumbers at Voyager Plumbing for a fast, reliable solution.
When You Should Call a Professional Plumber
While this guide gives you the confidence to tackle a straightforward washer replacement, the smartest DIY-er knows when to put the tools down. Sometimes, the best and most affordable move is to call in a licensed plumber.
Knowing your limits can be the difference between a smooth installation and a frantic call to fix a sudden flood. A professional plumber from Voyager ensures the job is done right, compliant with all regulations, and won't leave you with any nasty surprises.
Red Flags That Scream "Call a Pro"
Certain situations can quickly turn a simple swap-out into a job for the experts. If you come across any of these warning signs, it’s time to pick up the phone instead of the wrench.
Imagine this: your water taps look ancient, are caked in rust, or just won't budge. Trying to force them can snap the connection right off the pipe, leading to an uncontrollable water leak inside your walls or laundry. A plumber has the right gear and experience to handle this without causing a disaster.
Here are a few other clear signs you need professional help:
- Non-Compliant Plumbing: If your pipes or drainage look like they haven’t been touched in decades, they probably don't meet current Australian Standards. A licensed plumber is legally required to perform the necessary upgrades.
- New Connections Needed: Thinking of moving your laundry to another room? Running completely new water and drain lines is a major job that is absolutely not for amateurs.
- Dodgy Electricals: Is the power point old, loose, or not a proper three-prong grounded outlet? Don’t risk it. We can help coordinate with a licensed electrician to get it sorted safely.
- Strict Strata Rules: Many Sydney apartment buildings have by-laws that demand all plumbing work be handled by a licensed and insured professional. This is to protect the entire building from the risk of water damage.
A Voyager Plumbing professional does more than just connect two hoses. We assess your whole setup: checking water pressure, making sure everything is up to code, and ensuring every component is sound for a leak-free installation that will last.
If you hit a snag or just don't feel 100% confident, it's always better to be safe than sorry. There are some clear indicators that you should stop and call in an expert.

Your Washing Machine Questions, Answered
Even with the best guide, a new appliance install can throw a few curveballs. We get calls about washing machine setups all the time, so we've put together answers to the questions our plumbers hear most often from Sydney homeowners.
Do I Really Need a Plumber to Install My Washing Machine?
Honestly, it depends. If you're just swapping an old machine for a new one and the taps and pipes are in good nick, you can often tackle it yourself.
However, we strongly recommend calling a professional if you're dealing with:
- New water lines: Running new plumbing requires a licensed plumber to meet Australian Standards.
- Old, seized, or leaking taps: Trying to force old taps is a fast way to cause a flood. We can replace them properly.
- Strata properties: Many apartment buildings in Sydney have specific by-laws about plumbing work to protect other units. A licensed plumber ensures everything is compliant.
What are the Must-Have Tools for a DIY Install?
You don't need a whole workshop, but a few key items will make the job much smoother. At a bare minimum, you'll want:
- An adjustable wrench or a pair of channel-lock pliers for the hoses.
- A spirit level to get the machine perfectly balanced (this stops it from rattling your house apart during the spin cycle!).
- A bucket and some old towels for the inevitable drips when you disconnect the old machine.
A Pro Tip From Our Plumbers: Never, ever reuse old inlet hoses. The rubber washers inside perish over time, and they're one of the biggest culprits for those sneaky, slow leaks that cause serious water damage behind your machine. Always start fresh.
How High Does the Drain Hose Need to Be?
This one is crucial for making sure your machine doesn't flood or fail to drain properly.
According to Aussie plumbing standards, the top of the drainpipe (the standpipe) or the bend where the hose connects to your laundry sink trap must be between 600mm and 900mm from the floor. This specific height creates the right pressure to stop water from siphoning back into your machine or flowing out when it shouldn't.
If you’ve hit a snag, those old taps won’t budge, or you’d just rather have the peace of mind that comes with a professional installation, the team at Voyager Plumbing is always ready to help.
