The short answer
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 door seal leaking, so humid air condenses inside.
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 Silhouette Professional refrigerator
- Door seal leaking, so humid air condenses inside — This produces water inside the cabinet with no plumbing involved at all. Ranked first on a Silhouette Professional refrigerator: it produces water without a pipe being involved, which is why it is so often missed.
- 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 — The drain relies on gravity, and a cabinet tipped the wrong way holds the water instead of shedding it.
- 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.
Check in this order, and why
- Close the door on a sheet of paper right round both doors — Anywhere the paper slides out freely is where the humid air gets in.
- Look for water or ice under the crisper drawers at the back of the cabinet — Water pooling there is the drain, not the plumbing.
- Level the cabinet front to back and check the doors swing closed on their own — Most cabinets are set slightly nose-high so the doors close themselves.
What an owner can safely check
- Test both door seals with paper, then wash the gaskets and check the doors close square — A gasket that is clean, warm and sealing stops the condensation at source.

- 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. Door gaskets, hinges and lighting on the Professional units are serviceable parts, so price the door repair before you assume the cooling system is at fault.

What this page does not cover
This is the generalised Silhouette Professional 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.
