An ice maker that stops while water shows up on the kitchen floor is a specific signal: the water side of your fridge has a problem. The trick is figuring out which side. Is it the ice maker and its supply line, or the fridge’s defrost drain backing up? From across the room they look the same. They aren’t the same repair, and they don’t cost the same either.

Read Where the Water Lands
Location does most of the work here.
Back or side of the fridge, down low. That’s the supply-line zone. The line, the shutoff, and the inlet valve all live at the rear. A puddle creeping out from behind the unit points here. Pull the fridge out a foot and look for a wet line or a damp valve body.
Freezer floor or under the crisper drawers. That’s a defrost-drain problem, not an ice maker one. Frost melts on the defrost cycle and is supposed to run to a pan underneath. When the drain clogs with ice or sludge, the meltwater backs up and spills inside. We walk that path in our refrigerator leaking water diagnosis guide.
Around the door seal. Beads on the gasket are a seal issue, not a leak. It drips, but it won’t build a real puddle.
Empty ice bin and water at the back at the same time? You’re on the water line. Keep reading.
The Four Usual Suspects on the Supply Side
When ice stops and the leak is on the supply side, it almost always traces to one of these. This is common on every brand we run, Samsung, LG, Whirlpool, GE, Frigidaire.
1. The plastic supply line. Older fridges shipped with a thin plastic line that turns brittle and cracks at the bends. A hairline crack drips slow and starves the maker at the same time. We swap it for braided stainless, which outlasts the fridge.
2. The saddle valve. The little piercing tap older installs used. The gasket dries and weeps, or the pierced hole clogs to a trickle. Low flow means a half-frozen maker and a slow leak at the valve. A proper quarter-turn shutoff fixes both, but it needs the water off and the right fittings.
3. The inlet valve. The electrically driven valve at the back that fills the mold and the dispenser. When the solenoid sticks or the body cracks, you get drips and weak fill. Wiring is involved, so it’s a tech job.
4. A frozen fill tube. The small tube dropping water into the mold freezes solid if the freezer runs too cold or the seal is weak. Water overflows the tube and refreezes outside the mold, and no fresh cubes drop. Keep-refreezing means the cause behind it, thermostat, seal, or airflow, needs a diagnosis.
Off-tasting ice or small cloudy cubes alongside slow fill can also be a tired filter mimicking a flow problem. Our refrigerator water filter replacement guide covers that check.

Before You Call
Shut the water off behind the fridge or under the sink, then pull the unit out. Note which connection looks wet and where the puddle starts. Check whether the filter is past its change date, since a clogged one can look like a flow problem.
That’s the useful end of the visual check. From here it’s wiring on the inlet valve, live fittings under pressure on the line and saddle valve, or working out why a fill tube keeps freezing. Grab the wrong part off a shelf and you don’t just miss the leak, you can make it worse.

FAQ
Ice maker not working and leaking? Together those point at the water side: supply line, inlet valve, or fill tube. A crack or a slow-leaking valve kills ice and drops water at once.
How do I tell an ice-maker leak from a fridge leak? Water at the back near the connection, plus no ice, means the supply line. Water on the freezer floor or under the crispers means the defrost drain.
Should I fix it myself? The filter check and a visual are worth doing. Past that it’s tools and live water or wiring, and getting it wrong usually means a second call.
