The short answer for the NPWHI models
On the Alcove NPWHI refrigerator models, water appearing inside the cabinet or on the floor beneath it leads with frost melting from a heavy build-up rather than with the cause the brand-generic article opens on. The spine for the NPWHI family lists a single model code, so there is no variant spread to account for here.
What you observe on these models
- A puddle on the floor at the front of the cabinet — It has run forward from the base, which is what happens once the interior has filled.
- The puddle appears on a rhythm, every few hours — That rhythm is the defrost cycle, and it is close to a diagnosis on its own.
- Water pooling under the bottom drawer inside the cabinet — Interior water with a dry floor points at the drain or at condensation rather than at the supply.
- NEAR MISS — the floor is wet and so is the cupboard next to it — Check the plumbing in that cupboard before blaming the appliance.
Causes, most likely first on the NPWHI family
- Frost melting from a heavy build-up — This looks like a drain fault and is really a frost fault, so clearing the drain alone will not stop it. Ranked first here.
- A drip pan overflowing or sitting out of position — It is underneath, it is easy to reach, and it is worth looking at before anything is dismantled. Second.
- A cracked drain pan or an internal line — A split moulding or a damaged internal line. Last, and that is the point of the order: it is the least likely here and the only one that is not owner work.
- Body: The cause that moves up on these models is frost melting from a heavy build-up; what moves down to make room for it is a blocked defrost drain, which is where the brand-generic article for this symptom opens.
Check in this order, and why
- Note whether the puddle returns on a schedule or arrives continuously — First: A rhythm points at defrost; a steady arrival points at supply.
- Look underneath for the drip pan and whether it is overfull or out of position — Second: It is the easiest thing on the list to reach and it often answers the question.
- Close the door on a strip of paper at several points along the seal — Third: Anywhere it slides free, damp air is entering and condensing inside.
- Unplug the cabinet and see whether water keeps arriving — Fourth: Only the supply line leaks with the power off. That single test splits the list in two.
Before you open anything
Safety
Power off at the plug or the breaker before anything is opened. A capacitor keeps its charge after the switch, and the fan behind the rear panel can start on its own. The sealed refrigerant side is licensed work rather than owner work. Deal with the food first: a refrigerator holds food safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below, and a freezer at 0 degrees Fahrenheit.

When to call a technician
Stop and call at the point where a panel has to come off with power on, and call without hesitating if what you are looking at is a cracked drain pan or an internal line. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
