Water leaking from under your fridge is often caused by a blocked defrost drain, a damaged water line, a cracked drain pan or excess condensation. While some causes are simple to resolve, others require professional attention to prevent damage to your flooring and the refrigerator itself. Selective Fridges provides expert mobile fridge repairs across Perth, quickly identifying the source of leaks and restoring your appliance to proper working order.
Why Is Water Leaking From Under My Fridge?
Finding a puddle of water beneath your refrigerator is never something you should ignore.
Although it may seem like a minor inconvenience, water leaks are often the first sign that something inside the refrigerator isn’t functioning correctly. Left untreated, even a small leak can damage flooring, cabinetry and internal refrigerator components.
At Selective Fridges, leaking refrigerators are among the most common service calls we attend across Perth. Fortunately, many of these faults can be repaired quickly when diagnosed early.
What Causes Water to Leak From Under a Fridge?
Several different components can cause water to escape from your refrigerator.
The most common causes include:
- A blocked defrost drain
- A frozen defrost drain
- A cracked or overflowing drain pan
- Damaged or loose water supply lines
- A leaking water filter
- Excess condensation caused by faulty door seals
- Ice build-up affecting the defrost system
- An uneven refrigerator preventing proper drainage
Because several different faults can produce the same symptom, identifying the true cause is important before attempting repairs.
Before You Call for a Repair
Not every leak requires immediate repair. There are several simple checks you can perform first.
A Five-Minute Check You Can Try
Before booking a technician:
- Check whether the water is clean or discoloured.
- Inspect the water dispenser or ice maker supply line for obvious leaks.
- Ensure the refrigerator is sitting level.
- Look inside the freezer for excessive ice build-up.
- Check whether the door seals are closing properly.
- Remove any items blocking the internal drain channel if visible.
If water continues to appear after these checks, professional diagnosis is recommended.
What We Found This Week
A recent customer in Perth noticed a small puddle forming under their fridge every morning. They initially thought the appliance had a cracked water line.
After inspecting the refrigerator, we found the real cause was a blocked defrost drain. During each automatic defrost cycle, the melted frost had nowhere to drain, eventually overflowing onto the kitchen floor.
After clearing the blockage and confirming the drainage system was operating correctly, the leak was completely resolved without requiring major repairs.
It’s a good example of why the visible symptom isn’t always the actual problem.
Can Ice Build-Up Cause Water Leaks?
Absolutely.
One of the most common causes of water leaks is excessive ice forming inside the freezer.
As the ice melts during the defrost cycle, water can overflow if the drain is frozen or blocked.
If you’ve also noticed frost accumulating inside your freezer, it’s worth reading our guide on What Causes Ice Build-Up Inside a Frost-Free Fridge?, as the two problems are often related.
When Should You Be Concerned?
Water leaking from under a fridge should be inspected promptly if you notice:
- Water appearing every day
- Water inside the fresh food compartment
- Ice forming on the freezer floor
- Warm temperatures inside the fridge
- Electrical tripping
- Unusual noises developing at the same time
These symptoms often indicate an underlying cooling or defrost issue rather than a simple blocked drain.
Why Early Repairs Matter
Many homeowners simply wipe up the water and continue using the fridge.
Unfortunately, the leak usually returns because the underlying fault hasn’t been addressed.
Ignoring a persistent leak may lead to:
- Damaged flooring
- Swollen kitchen cabinetry
- Mould growth
- Reduced cooling efficiency
- More expensive repairs later
Early diagnosis is usually the most economical solution.

Frequently Asked Questions
Why is my fridge leaking water onto the floor?
The most common causes include a blocked defrost drain, frozen drain tube, damaged water line or excessive condensation caused by faulty door seals.
Can a blocked drain cause water under my fridge?
Yes. A blocked defrost drain prevents melted frost from draining correctly, allowing water to overflow onto the floor.
Is it safe to keep using a leaking fridge?
Small leaks may not be immediately dangerous, but persistent leaks should be inspected to prevent electrical issues, floor damage and further appliance faults.
Can ice build-up cause water leaks?
Yes. Excess ice can block the defrost drainage system, leading to water overflowing during the automatic defrost cycle.
Is repairing a leaking fridge worth it?
In many cases, yes. Most leaking fridge faults are considerably less expensive to repair than replacing the appliance or repairing water-damaged flooring.
