Jenn-Air JB36NXFXLE 36 in Built-In French Door Refrigerator with Preserva Food Care MECH-02 Error Fix: Water Dispenser Not Working or Low Flow

Error code MECH-02 on the Jenn-Air JB36NXFXLE 36 in Built-In French Door Refrigerator with Preserva Food Care means: Water Dispenser Not Working or Low Flow. The water dispenser does not dispense water or flow is very weak — the most common cause is a clogged water filter (replace every 6 months); the filter is typically located inside the refrigerator compartment (upper right, base, or behind a grille depending on model); check the water supply line behind the refrigerator for kinks; test the water inlet valve solenoid for continuity; on Jenn-Air built-in models with internal dispensers, check the dispenser tubing for kinks or ice blockages, particularly where the tubing passes through the freezer section on its way to the door dispenser
