The short answer
Start with a blocked defrost drain: on refrigerators of this brand it outranks the ice maker fill overshooting, and both come a long way before the supply line and its connections. A compact unit moves the ranking towards its installation: these are light machines that get relocated, stood on whatever is available, and squeezed into spaces that were never designed for them. Most of what follows is owner-checkable, and the point where that stops is stated plainly below.
What you observe
- A wet patch that comes back after wiping — A continuous source rather than a one-off spill; it is worth finding where it starts.
- Beads of water on the inside walls — Condensation from warm humid air entering the cabinet, which is a door problem rather than a plumbing one.
- Water under the crisper drawers — The classic signature of a blocked defrost drain: melt water backing up inside the cabinet.
- 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 this brand
- A blocked defrost drain — This is the single most common refrigerator leak there is. The clue is timing: the water appears in batches, several hours apart, because the defrost cycle runs at intervals rather than continuously. First, and the rest of the order follows from it: it leads because water under the crisper drawers has one likely cause and this is it.
- The ice maker fill overshooting — This one is identified by looking rather than testing: a slab of ice under or behind the ice maker, rather than cubes in the bin, is conclusive. Next, and close behind the first: this rank reflects that the evidence is visible in the freezer rather than needing any dismantling.
- The drain pan underneath — A pan problem gives water on the floor with a dry cabinet, which separates it immediately from the drain fault above. Third, once the two above are clean: it ranks here because the inside-versus-outside distinction does most of the diagnostic work for you.
- The supply line and its connections — Supply-side leaks do not care whether the unit is running, which is how they are told apart from everything else here. Last, and the placement is the point: it is second because it is the only leak here that continues while the appliance is switched off.
Check in this order, and why
- First: 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. It is first because it is the cheapest of the three to settle.
- Second: Look under and behind the ice maker — A slab of ice rather than cubes means the fill is overshooting or the tube is frozen.
- Third: Is the inside dry while the floor is wet? — Water outside with a dry cabinet is the pan or the plumbing, not the defrost drain.
What an owner can safely check
- 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
- Check the supply line and filter head — Dry every joint, put paper towel under each, and check them again after an hour.
Tools: torch, paper towelAbout 25 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.
Isolate before you start
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. Do not attempt anything on the sealed system: refrigerant work is licensed work. Never chip ice off an evaporator with anything metal, because piercing a coil ends the appliance.
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 Ningbo Patches Refrigeration Equipment Co Ltd refrigerators as a class, not for one family or one model. No family- or model-specific page for this brand and appliance is published here yet, so nothing narrower is linked; when one is, it becomes the more specific answer and this page will point to it. Deliberately absent: part numbers, wiring colours and the order the panels come off in — those belong with a named family.
