Common areas to inspect
Look for the location of the water: inside the compartment, beneath the unit, near an ice maker or around a water connection. The location helps distinguish drainage, condensation and supply-related problems.
Protect the kitchen
If water is actively leaking, protect surrounding finishes and shut off the appliance water supply when it is safe and you know the correct valve. Do not move a heavy built-in appliance without appropriate equipment.
Diagnosis before parts
Drain restrictions, water tubing, valves, ice-maker components and condensation can produce different leak patterns. The correct repair depends on identifying the source.
Frequently asked questions
Should I turn off the water if my Sub-Zero is leaking?
If the leak is connected to the water system and you can safely identify the appliance shutoff valve, stopping the water can help limit damage while service is arranged.
Can a clogged drain cause water inside the refrigerator?
Drainage problems are one possible cause of internal water, but the source should be confirmed before repair.
