Jenn-Air JS42NXFXDE Built-In 42 in 20.7 cu ft Built-In Side-by-Side Refrigerator with Advanced Water Filtration MECH-07 Error Fix: Water Leak Under or Behind Refrigerator

Error code MECH-07 on the Jenn-Air JS42NXFXDE Built-In 42 in 20.7 cu ft Built-In Side-by-Side Refrigerator with Advanced Water Filtration means: Water Leak Under or Behind Refrigerator. Water is pooling under or behind the refrigerator — the most common cause is a clogged defrost drain; during the defrost cycle, meltwater should flow through a drain tube from the evaporator area to an evaporation pan at the bottom of the unit; if the drain tube is clogged with ice or debris, water backs up, overflows the drain pan in the freezer, and leaks out; clear the drain with warm water poured from a turkey baster or a flexible drain snake; also check water supply line connections and the water filter housing for leaks
