Refrigerator is leaking water

A puddle by the fridge looks alarming, but the most common cause is a plugged drain you can often clear yourself in an afternoon — not a dead appliance.

Start here

In Canada, start by figuring out where the water is: open the freezer and look at the floor of the compartment. Ice or standing water pooling there, or dripping down inside the fridge, points to a clogged or frozen defrost drain — the most common cause by far. It's usually a DIY fix: thaw the drain and gently clear it, but unplug the fridge before you reach in near the coil.

visibilityHow to check

warning Unplug before you reach inYou'll be working with water inside a powered appliance, close to the defrost heater and wiring. Pull the plug (or switch off the breaker) before reaching into the compartment, and don't plug it back in until the area is dry. If the fridge is hard to move or the water is anywhere near the outlet, that's a sign to hand this off — see the escalation above.

Unplug the fridge before you reach inside near the coil — you'll be working close to electrical parts with water present.
Empty the freezer floor or lower compartment and look for a small drain hole, usually at the back near the base. Standing water, a puddle of ice, or a clogged opening around it points to a blocked defrost drain.
If you see an ice plug, the drain froze; if you see gunk or food debris in the hole, it's clogged. Either one backs water up into the fridge and onto the floor.

handymanHow to fix it

Unplug the fridge, thaw any ice in the drain, flush the drain line with warm water, gently clear the opening with a soft tube or pipe cleaner, and dry the area before restoring power.

Unplug the fridge and empty the freezer or lower compartment so you can reach the drain hole at the back.
If the drain is frozen, thaw it — a cup of warm (not boiling) water poured slowly into the drain, or letting the fridge sit unplugged with the doors open for a couple of hours, will melt the plug.
Flush the drain with warm water and gently work a soft plastic tube, turkey baster, or pipe cleaner through the opening to clear debris. Don't jam anything sharp or metal in — you can damage the drain or the heater near it.
Check the drip pan underneath is seated and empty, wipe everything dry, then plug the fridge back in. Watch over the next day to confirm the leak has stopped.

Clearing a refrigerator defrost drain is routine homeowner maintenance in every province.

handymanHow to fix it

Slide the fridge out, pull the drip pan from underneath, empty and clean it, check it for cracks, and slide it back squarely into position.

Ease the fridge out from the wall (or remove the front kick-plate on some models) to reach the shallow pan sitting under the compressor.
Slide the pan out, empty it, and wash it — a musty smell or slimy film is normal from standing water.
Inspect it for cracks; a cracked pan needs a matching replacement. Slide the clean pan back in squarely so drain water lands in it and can evaporate.

handymanHow to fix it

Close the water shut-off, dry the fittings, tighten or replace the leaking compression fitting or supply tube, then restore water and watch for drips. Call a plumber for the water connection if you're unsure.

Find the shut-off feeding the fridge — usually a small saddle or quarter-turn valve under the sink or behind the fridge — and close it. Dry everything so you can see the actual leak point.
Snug the leaking compression nut a quarter-turn; if the tube or fitting is cracked or a saddle valve is weeping, replace it with a matching line and fitting.
Reopen the water slowly and watch the fitting for several minutes. Any drip means shut off again and re-seat — and if the water connection is beyond a simple fitting, this is a fast, safe job for a plumber.

Homeowners may generally repair a fridge water-supply fitting themselves, but the actual water connection (saddle valve, house supply) is licensed plumbing work in some cases — call a plumber for the water line if the fix goes beyond a simple compression fitting.

verifiedWhy this one goes to a pro

The internal water reservoir and the electric inlet valve are wired and plumbed inside the cabinet, behind panels, close to live components. Diagnosing and replacing them safely means isolating power and water and reassembling watertight. In Canada this is a job for a licensed appliance technician — the part is inexpensive next to the cost of a shock or a hidden leak.

Your notes travel with the request — what you saw, what you ruled out, when it started — so the pro arrives with a head start instead of a mystery.

Why the list is in this order

We don’t sort by likelihood alone. We sort the way a good, honest tradesperson thinks: rule out the free, safe, common causes first. That’s why the cheap checks outrank the expensive repairs — and why anything dangerous gets a hard stop instead of a pep talk. The order exists to save you money, not to sell you anything.
