The short answer
A GRS refrigerator leaking water is usually a blocked defrost drain rather than a burst line: the drain ices over, the defrost water has nowhere to go, and it runs out under the crisper or down the back. On this build these ship as compact units into small kitchens and second homes, and they are worked far harder than their duty rating expects, which is why the drain comes first below. Clean water at the front and water at the back mean different faults.
What you observe
- Water pooling under the crisper drawers — The defrost drain is blocked and the water is taking the only route left to it.
- Ice building on the freezer floor under the vent — The drain is frozen rather than merely blocked, which is the same fault earlier in its life.
- Water running down the inside of the door — Condensation from a seal that no longer closes, not a plumbing fault at all.
- NEAR MISS: water inside and nothing cold — Cooling has failed and what you are seeing is the cabinet thawing. Read the cooling page first.
Causes, most likely first on this build
- Cabinet not level, so water runs forward instead of to the drain — Ranked first on this build: these are levelled by eye during a quick installation, and a cabinet tipped forward sends defrost water out of the door instead of down the drain.
- Door seal failing, so warm moist air condenses inside — Second: a hardened gasket or a door that no longer self-closes condenses room moisture onto every cold surface.
- Blocked or frozen defrost drain — Third: the single most common refrigerator leak on any build, and the cheapest to clear.
- Drain pan cracked, displaced or simply overfull — Last: uncommon, but worth a look while the grille is off anyway.
Check in this order, and why
- Look for ice on the freezer floor under the rear vent — Ice there is the blocked drain caught early, and it confirms the diagnosis without any tools.
- Check the cabinet is level and tips back very slightly — A clear drain still fails on a cabinet that leans forward.
- Feel along the supply line and its fittings with a dry tissue — Only after the drain, because it is the less likely of the two and the harder to reach.
What an owner can safely check
- Flush the defrost drain from inside the freezer with warm water — Find the drain hole under the rear vent and flush it until it runs freely. Do not push anything rigid down it.
Tools: warm water, turkey baster or syringeAbout 20 min
- Set the feet so the cabinet stands firm and tips back very slightly — Water then runs to the drain rather than to the door, and the doors close themselves.
Tools: adjustable spanner, spirit levelAbout 15 min
- Dry the floor, lay kitchen paper under the cabinet and check it after a day — Paper tells you where a slow leak is arriving, which no amount of looking will.
Tools: kitchen paperAbout 10 min
- STOP HERE if the next step needs the rear panel off or a fitting opened under pressure — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Water and electricity share the space under a refrigerator, so switch off at the breaker before you kneel in a wet area or move a wet cabinet, and unplug it before removing any panel. Shut off the water supply at its valve before touching any fitting. The cabinet is heavy, and a wet floor makes walking it out genuinely dangerous, so get help.
When to call a technician
Call once the drain runs free, the cabinet is level and the seal holds and water is still arriving, because the next step is the evaporator drain trough behind the rear panel. Call at once if the water is arriving fast, or if it is running near a socket or an extension lead, and shut off the supply and the breaker first. Parts for a direct import come from the seller rather than a service network, so confirm the part can actually be had before paying for a diagnosis that ends in a back-order.

What this page does not cover
This page covers the GRS refrigerator as a class rather than one family or model line. Drain trough routing, pan variants, supply fittings and the seal part numbers used on individual builds are deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first; the nearest pages of this class are linked just above.
