The short answer
The order that matters here is a unit that defrosts by hand first, a blocked defrost drain next and the supply line and its connections last. There is very little mass and very little margin in these machines, so where one stands changes how it behaves. That ranking is the value of this page: the cheap causes are the common ones on Silhouette refrigerators, and the costly one is what people reach for first.
What you observe
- A pool on the floor at the front — Water that has run forward along the cabinet floor, or a drain pan that has overflowed underneath.
- Water only after a hot day or a big shop — More defrost water than usual, which overwhelms a drain that is already partly restricted.
- Ice under the freezer floor panel — The same blocked drain, one step earlier — the water freezes before it can back up into the fridge.
- NEAR MISS — water only in the ice bin, fused into a lump — That is a temperature or ice-production problem rather than a leak; the ice page covers it.
Causes, most likely first on Silhouette
- A unit that defrosts by hand — On a unit like this the leak is often the appliance working as designed and being left too long between defrosts. The drain, if there is one, is a small hole that blocks in one season. Ranked first on Silhouette: on a hand-defrosted unit this leads because the ice has nowhere to go until it is cleared by hand.
- A blocked defrost drain — Second here, and on most machines it would be at the top: water under the crisper drawers has one likely cause and this is it.
- A unit that is not sitting square — Levelling is behind several of the causes above rather than being a leak in itself. Third, once the two above are clean: it is here because it makes several of the causes above more likely and every test below more reliable.
- The supply line and its connections — On a plumbed unit the line runs from a valve to a filter head and on to the fill valve, and every one of those joints can weep. Bottom of the list, deliberately: the damage a supply leak does is out of all proportion to how hard it is to find.
Check in this order, and why
- First: Defrost it completely by hand — Empty it, leave it off with the door open until all the ice has gone, and dry it out before restarting. It is first because it is the cheapest of the three to settle.
- Second: Look for water under the crisper drawers — Lift the drawers out and look at the floor of the cabinet, then at the drain hole at the back.
- Third: Check the level front to back — A unit should sit level or tilt very slightly back, so doors self-close and water runs to the drain.
What an owner can safely check
- Defrost the unit fully and clear its drain hole — Switch it off, empty it, let the ice melt into towels, and clear the small drain hole at the back.
Tools: towelsAbout 60 min
- Clear the defrost drain from inside — Empty and remove the drawers, find the drain opening at the back of the cabinet floor, and flush it with warm water.
Tools: jug of warm water, towelsAbout 35 min
- STOP HERE if the next step needs a meter on live terminals — That is the line between an owner check and a service call, and it is not worth crossing.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel, and treat every capacitor as still charged: a capacitor can hold a charge after the power is off. Secure or remove the doors before moving a unit, get help with the lift, and never lay a refrigerator on its back. Do not put a heat gun anywhere near a cabinet full of plastic.
When to call a technician
The owner side here is the drain, the seals, the levelling and a look underneath. Past that the panels come off.

What this page does not cover
This is generalized information for Silhouette refrigerators as a whole, not for one product line. No line-specific page covers this particular problem yet, but the line-specific pages that do exist for this brand and appliance are linked below — if your unit is one of those lines, start there. No part numbers, no wiring detail, no dismantling sequence: those vary by family and are only useful beside the family they describe.
