As a homeowner, it can be a frustrating moment when the second you see that there’s water pooling underneath your fridge or leaking inside the shelves. What makes it even worse is that it all happens suddenly and you’re not sure what causes it.
Today, our experts are back with another helpful guide to help you out. This time, we will walk you through the most common reasons a fridge starts leaking, how to troubleshoot each issue, and when you definitely have to call in a plumber professional in Melbourne for leak detection service.
Pinpoint the Source of Your Fridge Leak
Before you’re thinking of pulling your fridge apart, it’s better to pinpoint where the water is actually coming from. This way, you will be able to confirm if there’s any underlying issue.
Here are a few spots you can check for early diagnosis:
- Water pooling inside the fridge or crisper drawers. You might deal with a clogged defrost drain.
- Water underneath the fridge. There could be a drain pan, a loose water line, or an unlevel fridge.
- Water leaking from the back of your fridge. This can be a cue for you to let a professional inspect the water supply line or ice maker connection.
- Excess condensation around the doors. You can check for any signs of worn or damaged door seals.
Common Causes of a Leaking Fridge

First off, we want to assure you that it doesn’t always mean that you need a new fridge.
So, whenever one of the parts in your refrigerator fails or gets blocked, that’s when things start to leak. And yep, even the tiniest issue in your fridge plumbing can lead to that dreaded puddle.
Here are the most common culprits behind a fridge leaking water:
1) Clogged Defrost Drain
This is the number one reason for water pooling underneath a fridge. Your fridge regularly defrosts itself, and that melted water usually drains into a small pan underneath.
But when the defrost drain gets clogged usually with food debris or ice, the water will simply go straight onto your floor.
2) Cracked or Loose Water Line
If your fridge has a water dispenser or ice maker, it’s connected to your home’s water supply via a small hose.
Over time, that hose can crack, loosen, or even pop out of place, especially if the fridge gets bumped or moved.
3) Faulty Door Seals
If the door seals are cracked, loose, or dirty, warm air can sneak into your fridge or freezer. That moisture builds up and eventually drips out as water under the fridge.
4) Tilted Fridge
Even something as simple as a slightly tilted fridge can cause drainage issues. If the appliance isn’t level, the defrost water might not make it to the drain pan.
5) Faulty Door Seal (Gasket)
If your existing fridge has a worn-out or damaged door seal (especially if you have an older fridge), this is where warm air can create excess condensation inside the appliance. This eventually can turn into dripping water or puddles underneath.
To test the seal’s quality, try closing the fridge door on a piece of paper or a dollar bill. Now, does it slide out easily without any resistance? If yes, that means the gasket may not be sealing properly.
You can purchase replacement gaskets that are widely available through appliance parts suppliers. and can usually be installed without professional help.
How to fix it:
- Clean the rubber gasket using warm water with soap.
- Look for any cracks, warping, or loose sections.
- Then, replace the damaged gasket. You can install the replacement without the help of a professional.
6) Blocked or Incorrectly Fitted Water Filter
Now, if you own fridges that come with built-in water dispensers or ice makers, did you know that the water filter itself can actually trigger a leak?
That is because the filter is not installed correctly or simply it’s overdue for replacement, which makes the water leak from the filter housing.
How to fix it:
- Remove the filter and check for any possible cracks or damage.
- Read the manufacturer’s instructions and reinstall it firmly.
- Replace the old or clogged filter. .
If replacing the filter does not seem to solve the issue, we recommend you call for an expert leak detection service to address the issue properly.
5 Ways to Fix Leaking Refrigerator
So, you’ve figured out where that water’s coming from—now let’s get into how to actually stop the leak.
With just a few basic tools (and maybe a towel), you can often sort out the issue yourself before it turns into a full-blown mess.
Here are five fixes you can try:
1) Clear a Clogged Defrost Drain

A clogged defrost drain is behind a ton of fridge leaking water complaints—and it’s a pretty straightforward fix.
How to do it:
- Unplug your fridge.
- Find the drain hole (usually at the back of the freezer section).
- Use a turkey baster or small funnel to flush warm water through the hole.
- If the clog is stubborn, carefully use a pipe cleaner or soft wire to dislodge it.
- Plug the fridge back in and monitor for leaks over the next day or two.
2) Inspect and Reconnect the Water Line

If you have a fridge with a built-in water dispenser or ice maker, your leak could be coming from the back—especially if the fridge plumbing connection has come loose.
How to do it:
- Carefully pull the fridge away from the wall and inspect the water lineCheck the thin plastic or braided line connected to your home’s water supply.
- Look for cracks, wet spots, or a loose connection.
- Tighten the fittings or replace the hose if it’s damaged.
3) Replace or Clean the Door Seals

Damaged seals can cause excess condensation—so if your water leaking from the refrigerator seems like more of a drip than a gush, check those rubber gaskets.
How to do it:
- Inspect the door gaskets for tears or gaps.
- Clean them with warm soapy water and a cloth—sometimes gunk is the only thing causing the issue.
- If they’re damaged or not sticking, order replacements and swap them out (most pop right into place).
4) Level Your Fridge

This might sound silly, but a poorly balanced fridge can mess with how water flows during defrost cycles—and cause it to puddle underneath.
How to do it:
- Grab a spirit level and place it on top of the fridge.
- Adjust the feet underneath (they usually twist) until the fridge tilts ever so slightly backward.
- This helps ensure melted water flows toward the drain pan instead of the floor.
5) Empty and Clean the Drain Pan

If your drain pan is cracked, full, or overflowing, you might be seeing water leaking from under your refrigerator.
How to do it:
- Unplug your fridge.
- Locate the drain pan (usually underneath the fridge, accessible from the back or front grill).
- Slide it out carefully, empty it, and clean it with mild detergent.
- If the pan is damaged, you’ll need to replace it.

FAQ about Leaking Fridge
Let’s walk through more common questions we get from homeowners who are trying to figure out why their fridge is leaking:
1) How to unclog a fridge’s defrost drain?
Unclogging a defrost drain is actually one of the easiest fixes for a leaking fridge.
Just unplug your fridge, locate the drain hole (usually near the back inside the freezer), and flush it with warm water. You can use a turkey baster or funnel for this.
2) What happens if a fridge drain hole is blocked?
If the drain hole is blocked, melted ice from the defrost cycle can’t escape to the drain pan underneath.
Instead, it builds up and eventually spills out onto your floor and causes water leaking from fridge complaints.
3) Where can I find the defrost drain on my refrigerator?
Most fridges have the defrost drain located at the very back of the fridge or freezer compartment.
You might need to remove a plastic panel or cover to access it. If you’re not sure where it is, your fridge’s manual (or a quick model-specific Google search) can point you in the right direction.
4) Why is my fridge leaking water from the bottom?
A leaking fridge from the bottom is usually caused by a clogged defrost drain, a cracked drain pan, or an unlevel appliance. Clearing the drain or adjusting the fridge’s position can fix the issue quickly.
5) Why is my fridge leaking water inside?
If water is pooling inside the fridge, like around the crisper drawers, the defrost drain is likely blocked. This is because instead of draining away properly, the melted water backs up into the fridge compartment.
6) Is a leaking fridge dangerous?
It can be dangerous if water on kitchen floors creates a slip hazard and moisture near electrical outlets or power cords increases the risk of electrical shock. The moment you notice water near electrical components, unplug the fridge right away and seek professional help.
7) How much does it cost to fix a leaking fridge in Australia?
Basic DIY fixes usually cost very little beyond your time. However, if a plumber is needed to repair a damaged water line or connection, costs in Australia typically range from $100–$250 depending on the leak’s complexity.
