Display shows E12 and the water dispenser does not operate or stops mid-flow (on plumbed-in models).

Safety first: Unplug the refrigerator and close the water supply valve before working on the water system.

E12 is associated with water inlet or flow issues on SMEG refrigerators with dispensers.

• Step 1 – Check water supply: Confirm that the household water valve feeding the fridge is fully open and that water pressure is adequate.
• Step 2 – Inspect for kinks: Pull the refrigerator forward and ensure the water hose is not kinked or crushed.
• Step 3 – Replace water filter: If fitted, replace the internal or external water filter according to SMEG guidelines. A clogged filter can trigger flow errors.
• Step 4 – Check for freezing: In very cold freezers, the water line in the door or behind the freezer wall can freeze. Defrost the unit for several hours and test again.
• Step 5 – Test inlet valve: Access the rear lower panel to locate the water inlet valve. Inspect wiring and connectors. A valve coil that measures open-circuit with a multimeter is faulty and should be replaced.
• Step 6 – Flow sensor: Some models use a flow meter; if the valve opens but no pulses are detected, the flow sensor may need replacement by a technician.
