The short answer
On the HD family a leak that does not follow the defrost cycle is a plumbing leak, and that is the first thing to establish. A supply leak and a drain leak look identical on the floor and are completely different repairs. The timing tells them apart before anything is moved.
What you observe on these models
- Water pooling under the front edge of the cabinet — Water running forward along the floor of the compartment and out under the door is the classic blocked-drain pattern.
- A sheet of ice under the bottom drawer or on the compartment floor — Melt water that refreezes before it reaches the drain, which is the same blockage seen earlier in its life.
- Water at the back of the cabinet or under the compressor — That is the drain pan overflowing or a dislodged drain hose, and it is a different repair from the one above.
- NEAR MISS - a steady puddle that grows while the machine is idle — Water that keeps coming when the cabinet is not running is a supply-line leak, and that is a plumbing fault rather than a defrost one.
Causes, most likely first on this family
- Supply line, shut-off or inlet fitting weeping — First on this family when the cabinet is plumbed. Compression fittings behind the cabinet work loose, saddle valves weep, and plastic tubing splits where it was crushed when the cabinet was pushed back, and because the family is one platform whose model numbers share a prefix, the same fault turns up across the models listed above.
- Fill valve not seating after a cycle — Second. A valve that keeps passing a trickle after it closes floods the mould and then the bin, and the water finds its way to the floor by whatever route it can.
- Defrost drain blocked or frozen — Third on this ordering, and it is the fallback once the plumbing is proven dry. It gives the classic pool at the front edge, on the timing of the defrost cycle rather than continuously.
- Door seal and the drain pan — Last. Both make water appear on the floor and both are found in the same visit as the drain, so they sit at the end of the list rather than the start.
Check in this order, and why this family dictates it
- Close the water shut-off and watch the floor for a day — If the leak stops, it is the supply and nothing inside the cabinet needs opening.
- Dry the fittings behind the cabinet and put paper under them — Second: a weep shows itself on dry paper within hours, which is far more reliable than looking for a drip.
- Inspect the tubing where the cabinet sits on it — Third, because crush damage from pushing the cabinet back into place is the usual cause and it is visible.
- Then move to the defrost drain and the pan — Last, once the plumbing is ruled out, and the front or back position of the puddle points you at which.

Safety
Unplug the appliance or switch off its breaker before removing any panel, and mop up standing water before you work near the machine. A capacitor can hold a charge after the power is off, and water on a floor next to a running appliance is a shock risk in its own right. Close the water shut-off before touching any supply fitting.

When to call a technician
Call when the drain will not clear with warm water, when it blocks again within weeks of being cleared, when there is a heavy ice sheet on the evaporator, or when the water is arriving from a fitting you cannot reach. Note the model number from the table above so the correct gasket or drain kit comes with the visit.
