The short answer
On a recent installation the water is usually the supply connection or an unlevelled cabinet, not the defrost drain. Check behind the cabinet with a dry tissue before you empty the crisper drawers.
What you actually see and hear
- Damp at the back near the water connection — The supply fitting. Deal with this one first and fast.
- Water at the front on the floor — Often a cabinet leaning forward, sending condensate and melt the wrong way.
- Water under the crisper drawers — The defrost drain - less likely on a new cabinet but not impossible.
- Water appearing only after the cabinet was pushed back — A crushed supply line or a fitting disturbed by the move.
- NEAR MISS - beads on the interior walls in the first days — Condensation while a new cabinet pulls down. It settles.
Causes, most likely first on this machine
- Supply connection not properly seated — First on a new installation, and the one that does the most damage. A push-fit line that was not fully home weeps under mains pressure.
- Cabinet not levelled — Second. Delivery crews set cabinets down; levelling is the owner's job, and a forward lean sends water to the floor.
- Supply line crushed when the cabinet was pushed back — Third. It produces a leak that appeared suddenly with no other change.
- Transit packing left in the drain path or the drip pan displaced — Fourth. A pan knocked askew during handling overflows quietly.
- Defrost drain blocked — Fifth, and less likely on a new cabinet unless something was left inside it.
- An actual appliance fault or transit damage — Last, and a seller matter rather than a repair.
Check in this order, and why
- Dry the area behind the cabinet and check the fitting with a tissue — On a new installation this is the first and most urgent check.
- Check the cabinet is level with a slight backward tilt — Simple, free and frequently the answer.
- Look behind for a crushed or kinked supply line — Especially if the leak started when the cabinet was moved.
- Check the drip pan is seated and the drain path is clear of packing — Handling displaces both.
What an owner can safely check
- Dry behind the cabinet and check every water fitting with a tissue — Do this before anything else - mains pressure does not wait.
Tools: tissue, towelsAbout 15 min
- Turn off the water supply if any fitting is damp — Then have it reseated properly rather than tightening it blind.
About 10 min
- Level the cabinet on all four feet with a slight backward tilt — It fixes drainage, door swing and noise together.
Tools: spirit levelAbout 20 min
- Leave a loop of slack in the supply line behind the cabinet — So pushing it back cannot crush the line.
About 10 min
- Check the drip pan is square and no packing was left in the drain path — Handling displaces both routinely.
Tools: torchAbout 15 min
- STOP HERE if the connection keeps weeping after reseating — That is a plumbing job and, on a new appliance, a seller conversation.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. A freight-delivered cabinet should be stood upright and left to settle before it is switched on for the first time. The compressor and relay at the back stay live until the unit is unplugged, and the defrost heater on a frost-free cabinet sits behind the freezer rear panel - never chip ice with anything metal.
When to call a technician
Turn the water off and call a plumber for any weeping supply fitting - that is the leak with real consequences and it is plumbing rather than appliance work. Contact the seller for anything that looks like transit damage or a fault in the appliance itself. Levelling and slack in the supply line are owner jobs, take twenty minutes, and between them prevent most of the water that turns up behind a newly installed refrigerator.

What this page does not cover
This page is written for the freight-delivered full-size refrigerator class, not for one family or model line. Where a brand- or model-specific page exists for your unit it is the more specific answer and it is linked above, so go there first if your machine is named. What is deliberately not here: compressor and fan part numbers, thermostat ranges, door reversal instructions and shelf dimensions, all of which differ by family and belong on the page for that family.
