By Marcus Reed · Lead Sub-Zero Technician · 20+ yrs · Oakland & East Bay Water pooling under a Sub-Zero in Oakland is most often a frozen or clogged defrost drain backing up — not a true leak. Other causes are the water line/valve or a worn door gasket causing condensation. We clear and test the drain, or find the real source.
Frozen defrost drain
The most common cause: the defrost drain ices up and water overflows the pan area. Clearing and testing the drain usually resolves it.
Water line or gasket
Ice/water units can leak at the inlet valve or fill line; a tired gasket lets humid air in and causes condensation. We pinpoint the source instead of guessing.
