The short answer
When the CT family leaks, the drain channel behind the rear panel is the first suspect and the supply line is the second. Both are checkable without tools, which is not true of the causes the brand-generic article opens with.
What you observe
- Water on the floor at the front — The cabinet floor slopes forward, so a rear leak arrives at the front.
- Damp only at the back of the machine — Supply-side: the inlet connection or the line, and it will be wet when the unit is idle.
- Water pooling under the crisper drawers — The classic blocked defrost drain: melt water has nowhere to go and backs into the cabinet.
- A sheet of ice on the floor of the compartment — Same fault caught later, once the pooled water has frozen.
- NEAR MISS - condensation on the outside of the doors — That is humidity and seal performance, not a leak.
Causes, most likely first on CT
- Door seals and condensation — Ranked first on the CT family: a glass door on this class of unit condenses readily once the seal has taken a set. The order below follows the air path rather than the refrigeration circuit, which is a family property and not a model one. This moves above blocked defrost drain, which leads the brand-generic order, because this family is a single build with fixed access points.
- Water supply connection or line — Second: a small unit is moved more often than a built-in, and the line is strained every time.
- Blocked defrost drain — Third: a compact cabinet has a very short drain that a single piece of debris can close completely.
- Ice maker fill valve or its tubing — Fourth: last, and only relevant where a module is fitted, but a weeping fill valve leaks steadily rather than in step with the defrost cycle.
- Drain pan cracked or displaced — Last: the pan is small and shallow, so a unit that is not level overflows it.
Check in this order, and why
- Empty the compartment and find the drain opening — It is the likeliest cause and it is visible once the shelves are out.
- Check the cabinet is level and tilted very slightly back — A cabinet leaning forward sends melt water towards the door instead of the drain.
- Pull the unit out and look at the connection and the pan — Do this with the cabinet idle: supply leaks are wet when nothing is running.
- Test the seals with a sheet of paper around each door — Last, because it explains condensation rather than standing water.
Before you open anything
Safety
Kill the power at the breaker first, shut the water at the stop tap before touching a fill line, and call at once if you see oil at the compressor or smell burning.
When to call a technician
Shut the supply at the stop tap the moment a supply-side leak is confirmed. Clearing a drain and testing seals are owner work; a valve, a heater at the drain or a cracked pan is a service call on this family.
