The short answer
Water on the floor under a 51W396 refrigerator is nearly always one of three things: a blocked defrost drain, a supply connection, or condensate that never made it to the pan. None of the three is expensive, and two are owner work.
What you observe
- Water pools inside, under the crisper drawers — The classic blocked defrost drain: meltwater that should have run to the pan backs up into the lowest point of the cabinet instead.
- A sheet of ice forms on the floor of the freezer — Same blocked drain, caught earlier. The water freezes where it stands before it can reach the drawers below.
- Water appears at the back of the cabinet — That is the supply side — a fitting, the line to the ice maker or the dispenser — or a drain pan that has cracked or been knocked out of position.
- Water runs from the door or the dispenser — A dispenser line, or condensation running off a seal that is no longer sealing. Both leave a narrow trail rather than a pool.
- NEAR MISS — the leak only appears after an ice harvest — That points at the fill valve or the fill tube rather than the drain, and it belongs with the ice-maker checks instead.
Causes, most likely first on the 51W396 models
- The drain pan in the machine compartment has overflowed or cracked — Ranked first on this build: the pan is right behind the front grille, so when it fails the water arrives on the floor at the front immediately and obviously.
- The defrost drain is blocked — Second: the same meltwater, stopped further upstream, which pools inside the cabinet instead of reaching the pan.
- A supply or dispenser line at the back — Third: a slow weep that takes its time crossing the floor, which is why the front-grille causes outrank it here.
- The door seal — Last: real, but it produces damp and drips rather than the puddle that brings people to this page.
Check in this order, and why
- Pull the front grille and look at the drain pan — First on this build: it is the most likely cause and it is visible without moving the cabinet at all.
- Find where the water starts before you mop — Second: a pan that is dry means the water came from inside, and that sends you to the drain instead.
- Clear the defrost drain from inside the compartment — Third, and the repair for most of what the first two checks send you to.
- Check the supply fittings at the back — Last, because it is the slowest cause to show itself and the one that needs the cabinet moved.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Water and an energised appliance do not belong in the same job: dry the floor before you pull the cabinet out, and turn the supply off at the shut-off before touching any line fitting. Get a second person before you pull the cabinet out or tilt it. Never clear a drain with a wire or a metal probe.

When to call a technician
Call when the drain is clear, the seal is good and the water keeps coming back, or when the leak is at a fitting you cannot reach without disconnecting the supply. On the 51W396 models the line is the machine compartment: flushing a drain and tightening nothing is owner work, and anything that means separating a supply line under pressure is not. Call at once if water is reaching an outlet or a cord — kill the breaker first and do not plug it back in to test.
