A fridge leaking water is usually sending defrost meltwater the wrong way, or losing it from its supply line. The defrost drain is the most common cause: when it clogs or freezes, the water spills inside the refrigerator or onto the floor. Frigidaire names the other big one plainly: "Loose connections could cause water to leak to the floor." Most leaks are a drain or a water fitting, not a major part. If yours isn't, our fridge and freezer repair service covers every major brand.
Key Takeaways
- Water on the floor in front of the fridge, or under the crisper drawers, usually means a blocked defrost drain.
- Water at the back, or under the door on a dispenser model, points to the water line, valve or filter.
- Turn off the supply valve first and unplug the refrigerator before you clean anything.
- Flush a blocked drain with hot tap water, never boiling.
- Refrigerant never leaks as water. A puddle is not a Freon leak.
First, stop the water
If it's still dripping, turn off the supply valve that feeds the ice maker and dispenser. It is usually behind or under the refrigerator, or under the kitchen sink. Wipe the floor dry to protect your home and see where the leak starts. GE advises you to "unplug this appliance from the power supply" before cleaning, and Beko warns that "the compressor can be very hot" if you reach behind it.
Why is my fridge leaking water? Find the source
Where the puddle shows up tells you the cause of the issue. Match it to this table.
| Where the water is | Likely cause | What to do |
|---|---|---|
| Under the crisper drawers, inside the fridge | Blocked defrost drain, or a cracked water filter inside the cabinet | Steps 2 and 4 |
| Ice on the freezer floor | Frozen or clogged drain tube | Step 2, often a technician |
| On the floor in front, once or twice a day | Clogged defrost drain | Step 2 |
| On the floor at the back | Water line, connection or inlet valve; drain pan | Steps 3 and 4 |
| Under the door on a dispenser model | Dispenser water line or melted ice in the chute | Step 4 |
| Drops along the door edge | Door not closing, or a worn seal | Step 5 |
GE's clue for poor drainage: "water appears on the floor in front of the Refrigerator once or twice a day". When we reviewed the notes on 41 of our fridge leak calls, about 13 were a blocked or frozen defrost drain and about 13 were the supply side: a cracked line, dispenser tube, inlet valve, filter housing or ice-maker tray. Only 3 came down to the door gasket or the drip pan; the rest were other faults.
How to fix a fridge leaking water
- Check the fridge is level and the doors close. Samsung says to make sure the fridge is "tipped slightly backwards", so water runs to the drain. Frigidaire adds that a door left open lets the evaporator ice up, causing "water to leak from the bottom".
- Unclog the defrost drain. Unplug the fridge. Samsung says the drain is "a small hole that is usually located at the bottom of the freezer". GE's recipe is "1 tablespoon of baking soda and 2 cups of hot tap water", squeezed into the hole with a turkey baster. "When clear, you will hear water running down into the drain pan below." If the drain is frozen solid, a full manual defrost comes first; our guide to frost building up in a fridge walks through it.
Photo from one of our service calls in Vancouver: the defrost drain trough from a Frigidaire with condensation inside the cabinet. The drain line was blocked, so defrost water backed up into the fridge. Cleaning the drain line got it draining properly again. - Clean the drain pan. Samsung notes "The drip pan can become dirty and accumulate a build-up of debris." Check it isn't cracked or knocked out of place. To prevent a repeat, GE suggests flushing the drain with baking soda and hot (not boiling) water once or twice a year.
- Inspect the water line and filter. Shut off the supply valve, pull the refrigerator out and wipe each fitting with a dry paper towel to find the wet one. Frigidaire says to tighten connections and adds "Cracks in the water filter can cause leaking in the cabinet". Whirlpool says "Water found under the door could be from the dispenser water line." For drips at the dispenser itself, see our fridge water dispenser guide; for leaks around the ice bin, our ice maker guide.
- Test the door seal. Samsung warns "If the door isn't closing properly your appliance will heat up and water will begin to form." See our guide to a loose fridge door seal.
When a leak needs a technician, and what it costs
Call us if the drain refreezes within days or sits behind the freezer's back panel, or if the back of the fridge keeps leaking after you've checked the fittings. GE is direct: "If there is ice on the rear wall, or if cleaning the drain tube does not help, we recommend service."
On our Vancouver calls, we clear most drain leaks with steam or hot water and a manual defrost. Built-ins can take longer, because some need a full defrost before we can reach the drain. One built-in Sub-Zero had its drain hole plugged with grease and food. A dripping dispenser or a puddle under the unit was often a cracked water line, and replacing the line stopped it.
In Vancouver and the Lower Mainland, the diagnostic is $100, and it comes off the labour if you go ahead. Most repairs run $225 to $300 in labour with that diagnostic included. Parts are quoted before we order them. Built-in and high-end units cost more, because the repair starts with an uninstall. Our appliance repair cost page has the full breakdown. On an older fridge with several faults, our repair or replace guide helps you decide.
Fridge leak questions
What does a Freon leak look like in a fridge?
You usually won't see it. Refrigerant stays inside a sealed loop and escapes as a gas, so it never leaves a puddle of water. A leak shows up as a fridge that slowly stops cooling while the compressor keeps running. That takes a licensed sealed system repair; we hold Technical Safety BC licence BC30591 for refrigerant work.
Can leaking Freon from a refrigerator make you sick?
We can't give medical advice. Modern refrigerators use R134a or R600a. R600a is isobutane, and the hazard there is fire. LG's manual says: "When gas is leaked, do not touch the refrigerator or the outlet and ventilate the room immediately." If anyone feels unwell, call HealthLink BC at 8-1-1, or 911 in an emergency.
Where is the most common place for a Freon leak?
We haven't counted leak points across every sealed-system job, but the evaporator comes up again and again in our notes. On several Fulgor and Blomberg built-ins that stopped freezing, we found the sealed-system leak in the evaporator, and some were declared not repairable.
How long do refrigerators usually last?
We tell customers 12 to 17 years for a well-kept refrigerator. BC Hydro puts the typical lifespan at "about 10 to 15 years." A leak by itself rarely ends a fridge's life.
Still leaking? Call 604-265-3852 or book a visit online. We're open 8AM to 8PM, seven days a week, with weekend visits at the same price, across Vancouver and the Lower Mainland.
