The answer first
A leaking refrigerator is usually draining somewhere it should not, rather than losing water it was given. The ranking here starts at ice maker fill overshooting or the fill tube spraying.
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 — the cabinet is warm as well as wet — Treat that as a cooling failure first; the water is a consequence of the ice, not a leak.
Causes, most likely first on a Smad refrigerator
- Ice maker fill overshooting or the fill tube spraying — A fill that runs long, or a fill tube partly blocked with ice, puts water outside the mould. Ranked first on a Smad refrigerator: the water it spills is out of sight until it has already reached the floor.
- Water line, filter head or inlet valve leaking — A line pinched when the machine was pushed back can split and leak only under pressure.
- Defrost drain blocked — When the drain blocks, defrost water backs up under the drawers and then runs forward onto the floor.
- 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.
Check in this order, and why
- Look for a sheet of ice under the bin or water tracking down the freezer wall — Ice beneath the bin is overspray rather than a leak.
- Pull the cabinet out and dry every joint, then look again after an hour — A weeping joint shows itself as soon as the surfaces are dry.
- Look for water or ice under the crisper drawers at the back of the cabinet — Water pooling there is the drain, not the plumbing.
What an owner can safely check
- Switch the ice maker off for a day and see whether the water stops — If it does, clear the fill tube with warm air before turning the maker back on.
About 15 min
- Dry the filter head, the valve and every push-fit joint, then check them again after an hour with a torch — A joint that is wet again is the leak. Shut the supply valve off if you find one.
Tools: torch, paper towelAbout 25 min
- 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. If your unit is an absorption model running on gas, the gas side is not owner work: a licensed gas technician handles the burner, the flue and any smell of gas.

What this page does not cover
This is the generalised Smad 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.
