The short answer
Water in or under a Conservator GRM refrigerator has three possible origins and they are easy to tell apart: melt water that failed to drain, room air condensing on cold surfaces, or a supply connection on cabinets that have one. The brand-generic page establishes inside versus underneath first; that stands, and this family decides where to look next. Two cabinet sizes under one label means the same fault presents with different urgency: the smaller stem loses its margin quickly, the larger one hides the same fault for days. That moves the loading and door questions up on the small stem and the airflow questions up on the large one.
What you observe
- Water pooling in the bottom of the fresh-food compartment — Classic blocked defrost drain: melt water with nowhere to go, backing up into the cabinet.
- Ice forming under the crisper drawers — The same blocked drain a stage earlier, freezing where it collects instead of running away.
- Water under the front of the cabinet on the floor — Either interior water escaping under the door, or the evaporation tray overflowing at the back and running forward.
- NEAR MISS — water together with a cabinet that is not cold — Then the water is melt from a cooling fault and the cooling page is where to start.
Causes, most likely first on the GRM models
- Blocked defrost drain — First on this family, and by a wide margin. The drain is a small opening behind or beneath the evaporator, and it blocks with debris and with ice. Once it does, every defrost cycle deposits its water inside the cabinet.
- Door seal admitting room air — Second. Warm moist air that reaches cold surfaces leaves its water behind, and on a cabinet with a tired seal that happens continuously. It reads as a leak even though nothing is leaking.
- Air path length across the cabinet sizes — Ranked here because of the size spread in this table. A taller cabinet runs a longer air path with more cold surface for moisture to settle on, so it generates more frost for the drain to clear and reaches a visible leak sooner once the drain narrows.
- Evaporation tray overflowing or displaced — Third. The tray sits over the compressor so its heat can evaporate what the drain delivers; knocked askew during a move, it puts the same water on the floor.
- Supply line or fitting, where one is fitted — Fourth, and only on cabinets that take a water connection. A weeping compression fitting produces a slow, steady puddle that does not respond to anything you do inside the cabinet.
Check in this order, and why
- Establish which cabinet stem you own first — Decide which stem you own first — it is the digits in the middle of the plate code — because the order below branches on cabinet size at the second step.
- Establish whether the water is inside or underneath — Inside points at the drain and the seal; underneath and towards the back points at the tray or a fitting. The two paths share no steps.
- Clear the drawers and look for the drain opening — Standing water or ice over it is the answer. Clearing it is owner work; keeping it clear means asking why it froze.
- Test the seal with a strip of paper all the way round — Anywhere the paper pulls out freely is admitting the moisture that becomes the water.
- Look behind the cabinet at the tray and any fitting — A tray out of position, or a damp fitting on a supply line, shows itself immediately once you are looking in the right place.
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. Deal with standing water before you work rather than after, and keep the cabinet isolated while anything at the base is disturbed. Where a supply line is fitted, close its valve before touching a fitting. Never clear a frozen drain with a metal probe: the tubing is soft, and a punctured drain line turns a ten-minute job into a service call.

When to call a technician
Call when a cleared drain re-freezes within days, because that usually means the defrost side has a fault behind it rather than a blockage in front of it. On the larger stem call once the fault is behind the rear interior panel; on the smaller one the same rule applies a step earlier, because there is no room to work from the front. Call promptly for any leak at a supply fitting that does not stop when the fitting is re-seated, since a slow weep behind a cabinet does more damage to the floor than to the appliance.
