The short answer
On Fire Magic water in or under the cabinet is most often a blocked defrost drain. Ranked that way because the enclosure it is built into traps its own condenser heat, so anything that touches heat rejection outranks everything else.
What you observe
- Water at the back, on the floor behind the unit — The pan or the supply plumbing. Shutting the supply valve tells you which.
- Beads of condensation on the inside walls or on food — Humid air getting in past a seal, not a leak in the usual sense.
- NEAR MISS: the water is warm, or it is coming from a nearby dishwasher or sink — Dry everything, put paper down and find the actual source before blaming the refrigerator.
Causes, most likely first on Fire Magic
- The defrost drain is blocked — First on an outdoor unit, where ambient heat decides what the machine can do. Melt water that should run to the pan backs up instead, freezes into a sheet under the compartment floor, and then finds its way out under the crisper drawers or onto the floor. It is the most common source of interior water on almost any cabinet.
- The door seal is letting warm humid air in — Second, and the cause that changes most between a shaded island and full sun. Warm air meeting a cold surface condenses, and on a humid day that is enough to produce visible water with nothing broken at all. The giveaway is water and condensation that both get worse in warm weather and clear in winter.
- The cabinet is tilted forward — Third. The drain channel and the pan both rely on the cabinet sitting slightly back on its feet.
- A split liner or a failed evaporator drain weld — Last, and it is the reason the order above matters. Water appears inside the cabinet with a clear drain and a good seal, or reappears within days of every clearing.
Check in this order, and why
- Lift the crisper drawers and look for standing water or a sheet of ice under them — Water inside the cabinet almost always means the drain rather than the plumbing.
- Close the door on a sheet of paper at several points and check whether it slides free — A gap you cannot see is enough to condense water you can.
- Put a level on the top of the cabinet front to back — It explains water at the front of the floor with a perfectly healthy drain.
What an owner can safely check
- Clear the drain opening at the back wall with warm water and a soft flexible tube — Never use a metal wire.
Tools: warm water, turkey baster, soft tubingAbout 30 min
- Paper-test the gasket right round, then clean the gasket and the frame — Warm soapy water restores a gasket that has gone tacky.
Tools: a sheet of paper, warm soapy waterAbout 15 min
- Adjust the front feet so the cabinet sits level side to side and very slightly back — The doors should also swing closed on their own from half open when this is right.
Tools: spirit level, adjustable spannerAbout 20 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Water and electricity share the floor here. Switch off the breaker before mopping under or behind the cabinet, and unplug the appliance before removing any panel. Shut the water supply valve before touching any fitting, and expect the line to stay charged afterwards.
When to call a technician
Call when the interior fills again within days of a cleared drain, when the water is warm or discoloured, or when you cannot establish the source after the checks above. Call immediately if water is reaching an outlet, an extension lead or the compressor compartment, and switch the breaker off before you make the call rather than after it.

What this page does not cover
This page covers the brand and the refrigerator class, not one family or model line. Where a family-specific or model-specific page exists for your unit, that page is the more specific answer and it takes precedence over this one. Not here: part numbers, wiring colours and component locations, which differ by family.
