The short version
Water inside a Dongguan Shengqi Lighting Technology refrigerator, or on the floor in front of it, is nearly always defrost water that cannot reach its drain rather than a burst supply line. The first two causes below are owner work; only a cracked drain pan or a split line needs a visit.
The symptoms, including the ones that mean something else
- Water on the floor in front of the unit — It has run forward, which usually means the drain or the pan.
- There is no model information on the unit that anyone recognises — A factory relabel often carries a number that no parts catalogue lists.
- NEAR MISS: the cabinet is also warm — A leak plus warmth is usually a cooling fault first, and the cooling page covers it.
Causes in order of likelihood on this brand
- A blocked defrost drain — Every frost-free refrigerator melts its own frost and runs the water to a tray underneath. Ranked first on a Dongguan Shengqi Lighting Technology refrigerator: water that cannot get away produces symptoms all over the appliance, which is why the path is settled early.
- The water supply line or one of its fittings — The line that feeds the ice-maker and the dispenser is the one part of the unit under constant pressure. Ranked second on a Dongguan Shengqi Lighting Technology refrigerator: this is traced by hand from the valve to the appliance and it costs nothing to do.
- The unit tilted the wrong way, or its drain pan cracked — These cabinets are meant to sit very slightly back so water runs to the drain. Ranked third on a Dongguan Shengqi Lighting Technology refrigerator: relabelled units are shipped and set up by whoever sold them, and installation faults are common enough here to clear first.
- Humid air getting in past a tired door seal — Warm room air carries moisture that condenses the moment it reaches a cold surface, so a poor seal delivers water to the inside of the cabinet continuously. Ranked fourth on a Dongguan Shengqi Lighting Technology refrigerator: the sealing hardware is the factory’s standard part and it is the first thing to go soft on this platform.
What to check first, second and third
- Look for ice or standing water at the low point of the freezer floor — Water under the crispers with a dry supply line behind is this cause.
- Pull the unit out and look at the line and every fitting with a torch — Water at the back with a dry cabinet is a supply fault, not a drain fault.
- Check the unit sits level side to side and very slightly back — A unit tipped forward leaks forward, which is exactly what the owner sees.
What an owner can safely check
- Empty the unit, switch it off and let it stand with the doors open until the drain runs clear — Do not push anything metal into the drain hole: the tubing behind it is soft.
Tools: towels, warm waterAbout 90 min
- Dry every fitting, then check them again after a few hours to see which one is wet — Do not overtighten a compression nut: that is how a drip becomes a flood.
Tools: torch, paper towelAbout 20 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you touch anything
Safety
Unplug the unit or switch off its breaker before removing any panel: a capacitor can hold a charge after the power is off. Refrigerant work is licensed work, so never cut, bend or solder the tubing, and never run the unit with the sealed system open. A loaded refrigerator is heavy and top-sided, so get help to move it rather than walking it on a corner.
When this becomes a service call
Call when the drain is clear, the unit is level and the seal is good, and water still appears: what is left is the drain tube behind the liner, the pan, or the defrost control. Call immediately if the water is at the back near the supply line and you cannot see which fitting is wet, because a pressurised line behind a refrigerator can empty into a floor for a long time before anyone notices.

What is deliberately not here
This page is written for the Dongguan Shengqi Lighting Technology refrigerator as a class, not for one family or model line. Shelf layouts, defrost-control types, fan placement and part numbers all change from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, it is the more specific answer and the one to read first.
