The answer first
Water under a refrigerator comes from one of three places: the defrost drain, the water line, or condensation. On this machine the first suspect is cabinet out of level, so the drain does not fall to the pan.
What you observe
- Water under the crisper drawers inside the cabinet — Classic blocked defrost drain: the water backs up and over.
- A puddle on the floor at the front — Water has run forward under the cabinet, which usually means the drain or the pan.
- A puddle at the back or under one corner — Points at the supply line, the valve or a cabinet that is out of level.
- NEAR MISS — water appears only when the dispenser is used — That is the dispenser line or its drip tray, and it has its own fix.
Causes, most likely first on a Signature Kitchen Suite refrigerator
- Cabinet out of level, so the drain does not fall to the pan — Out of level, the doors also stop sealing squarely, which adds condensation to the drain problem. Ranked first on a Signature Kitchen Suite refrigerator: it is the cause that makes the other causes worse, and it is fixed with a spanner in a quarter of an hour.
- Defrost drain blocked — When the drain blocks, defrost water backs up under the drawers and then runs forward onto the floor.
- Drain pan cracked, displaced or overflowing — In a humid room the pan can simply be given more water than it can evaporate.
- Door seal leaking, so humid air condenses inside — Warm room air entering past a tired gasket condenses on the cold walls and runs down them.
Check in this order, and why
- Level the cabinet front to back and check the doors swing closed on their own — Side-to-side level matters for the drain fall as well.
- Look for water or ice under the crisper drawers at the back of the cabinet — Water pooling there is the drain, not the plumbing.
- Pull the lower grille and look at the pan with a torch — A pan that is simply full points at a humid room rather than a fault.
What an owner can safely check
- Level the cabinet on its feet, slightly nose-high, and check each door closes itself from half open — A cabinet sitting correctly drains to the pan and seals its own doors.

- Empty the lower shelves and flush the drain opening at the back with warm water from a turkey baster — Warm water clears an ice plug and most debris. Never force wire down the drain.

- STOP HERE if the next check needs a panel off or a meter on live terminals — That is where the owner checks end and a service call begins, whatever the ranking says.
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. Leave the door switch wired as you found it. Never take a knife, a screwdriver or a heat gun to frost on an evaporator: the tubing behind it is thin, pressurised, and a puncture ends the appliance. Empty a loaded cabinet before you move it.
When to call a technician
Owner work here is the drain, the pan, the seals and the levelling. A weeping valve, a split line inside the cabinet and a drain blocked beyond the opening are technician work — and a mains leak should have the supply valve shut immediately. Use an installer or technician authorised for the line: panelled and integrated machines can be damaged by the removal itself, and the trim and hinge hardware is specific to the family.

What this page does not cover
This is the generalised Signature Kitchen Suite refrigerator page. A family- or model-specific page, where one exists, is linked above and is the more precise answer for your unit. Left out on purpose: part numbers, connector colours, the order panels come off in, and every torque figure — a generalised page cannot be right about any of them.
