A refrigerator ice maker that stops making ice while water shows up on the kitchen floor is a specific signal. The water side of your fridge has a problem, and the trick is figuring out which side. Is the leak coming from the ice maker and its water line, or from the refrigerator’s drain and defrost system? They look similar from across the room. They are not the same repair.
Here’s how to read the symptoms before you grab a towel and a flashlight.
Start With Where the Water Lands
Location tells you most of the story.
Back or side of the fridge, near the floor: This is the water-line zone. The supply line, the shutoff valve, and the water inlet valve all live at the rear of the unit. A puddle that creeps out from behind the fridge points here. Pull the unit out a foot and look for a wet supply line or a damp valve body.
Inside the freezer floor or under the crisper drawers: This is a defrost-drain problem, not an ice-maker problem. Frost builds up, melts during the defrost cycle, and the meltwater is supposed to run down a drain to a pan underneath. When that drain clogs with ice or gunk, water backs up and overflows inside. We cover that path in detail in our refrigerator leaking water diagnosis guide.
Around the door seal: Condensation beading on the gasket is a seal issue, not a leak. It drips, but it won’t make a real puddle.
If the ice maker is empty AND the water is at the back, you are looking at the water line. Read on.
The Four Usual Suspects on the Water Line
When ice production stops and the leak is on the supply side, it almost always traces to one of these.
1. The plastic supply line. Old fridges came with a thin plastic line that turns brittle and cracks, especially at the bends. A hairline crack drips slowly and starves the ice maker at the same time. A tech will replace it with a braided stainless line that lasts far longer.
2. The saddle valve. This is the little piercing tap on your home water line that older installs used. The internal gasket dries and weeps, or the pierced hole clogs and chokes water flow to a trickle. Low flow means a half-frozen ice maker and a slow leak at the valve. Replacing it with a proper quarter-turn shutoff fixes both problems, but it’s a plumbing job that needs the water off and the right fittings.
3. The water inlet valve. This electrically controlled valve at the back of the fridge opens to fill the ice mold and the dispenser. When the solenoid sticks or the valve body cracks, you get drips and weak fill. This one involves wiring, so it is a technician job.
4. A frozen fill tube. The small tube that drops water into the ice mold can freeze solid if the freezer runs too cold or the door seal is weak. Water then overflows the tube and refreezes outside the mold, and no fresh cubes drop. If it keeps refreezing after a thaw, the underlying cause (thermostat, seal, airflow) needs a proper diagnosis.
If your ice tastes off or the cubes are small and cloudy alongside slow fill, a clogged filter can mimic a flow problem. Our refrigerator water filter replacement guide walks through that check.

Before You Call
Turn the water off at the shutoff behind the fridge or under the sink, then pull the unit out. Note which connection looks wet and where the puddle is coming from. Check whether the water filter is past its change date, since a clogged filter can look like a flow problem.
That’s the useful part of the visual check. From here the repairs involve wiring (inlet valve), live water fittings under pressure (supply line and saddle valve), or diagnosing why a fill tube keeps refreezing, which usually points to a thermostat or door seal issue. Getting the wrong part off the shelf doesn’t just fail to fix the leak; it can make the situation worse and complicate the actual repair.

FAQ
Why is my refrigerator ice maker not working and leaking water? Together those symptoms point at the water side: the supply line, water inlet valve, or fill tube. A cracked line or a slow-leaking valve stops ice and drops water at the same time.
How do I tell an ice-maker leak from a fridge leak? Water at the back or side near the supply connection, plus no ice, means the water line. Water inside the freezer floor or under the crispers means the defrost drain.
Should I try to fix it myself? The filter check and a visual inspection are worth doing. Anything past that involves tools and live water or electrical connections. Getting it wrong usually means a second call. We’re the faster path.
