The finding, first
A leaking refrigerator on this family is usually a blocked defrost drain, and the water appears a long way from where the problem is. Defrost water is supposed to run down a channel, through a tube and into a pan over the compressor; block any part of that and it goes somewhere else. Most of this page is owner work, and the part that is not is also the part that floods kitchens.
Where the water shows up
- A puddle on the floor at the front of the cabinet — Either the drain overflowing past the liner, or the drain pan at the back overfilled and sloshing.
- Ice building under the freezer floor or in the drawer — The same blocked drain, seen from the freezer side, where the water freezes before it can reach the compartment below.
- Water appears only after the icemaker fills — Points at the fill tube, the tray or the connection to it rather than at the defrost side.
- A damp patch appears and dries between uses — Small volumes arriving on a defrost cycle. That timing points at the drain rather than at anything plumbed.
- NEAR MISS — the cabinet is also warm — Then the leak is secondary to an airflow problem and the cooling page for this family is where to start.
The ranking for this platform
- Defrost drain blocked with ice or debris — First on this roster and not close. The drain entry sits in the coldest part of the cabinet, so a slow drain freezes shut, and food debris that reaches the channel completes the job over a season.
- Door seal set, torn or held open — Humid room air meeting cold surfaces. Commoner in summer, commoner still where a bottle or a shelf stops the door travelling the last few millimetres.
- Cabinet not level, tipping water the wrong way — The drain channel relies on gravity. A cabinet that leans forward sends condensate into the compartment instead of down the tube, and levelling it is a complete fix.
- Supply line, fitting or inlet valve leaking — Bottom by frequency and top by urgency. This is the only water on the page that is connected to a main, which means it does not stop when the cycle does.
Work in this sequence
- Establish whether the water is inside the liner or on the floor — Inside means condensate and the drain; outside at the back means supply. This single observation halves the list.
- Close the door on a strip of paper at several heights — Paper that slides out freely marks where the seal is not sealing, which is where the humid air is getting in.
- Dry everything, then look again after one defrost cycle — Establishes whether the water arrives on a schedule, which separates the drain from everything else.
- Put paper towel under the cabinet overnight — Where it wets first tells you front or back, and that halves the list before any panel comes off.
What to do before the panel comes off
Safety
Kill the supply before anything else happens: unplug it, or switch the breaker off. A capacitor can hold a charge long after the power has gone.

Where the owner line is
The owner line on this family is the drain channel. If flushing it from inside the cabinet does not clear it, the blockage is in the tube behind the liner and reaching it means the cabinet comes apart, which is service work on this roster.
