De'Longhi Magnifica S empty water circuit message

The Empty circuit / Fill water circuit message means the Magnifica S has not established normal water flow. Fill and seat the tank, fit the hot-water outlet, then prime from the control shown on the display.

Manufacturer sources consulted

This guide is for the explicit water-circuit message, not for slow coffee or a general descale reminder. Air can enter after the tank runs empty or is removed during use. Keep a sufficiently large cup beneath the hot-water outlet because priming releases hot water and may begin unevenly before a continuous stream appears.

Follow the checks in order and change only one condition at a time. Run a short rinse or test after each action, so the result identifies the cause instead of hiding it. The procedures below stay within the cleaning, refitting and user-menu operations described by the manufacturer.

Before checking De’Longhi Coffee machine

  • Switch the machine off, unplug it and let hot-water, steam and metal parts cool before removing or cleaning a component. Never open the casing.

What this symptom can mean on De’Longhi Coffee machine

Tank emptied or lost contactCheck the actual water level and lower the tank firmly into its seat. A full tank that is hovering above its connection cannot feed the circuit.
Air remains in the circuitIf the message follows an empty tank or first setup, the official hot-water operation gives the pump a direct route to replace trapped air with water.

3 checks for De’Longhi Coffee machine, starting with Fill and seat the tank

  1. Fill and seat the tank

    Remove the tank, fill it with fresh water to the permitted maximum and reinstall it fully so the bottom connection opens.

  2. Fit the hot-water outlet

    Attach the correct hot-water spout to its connection and place a large heat-resistant cup below it before confirming the operation.

  3. Confirm the priming operation

    Press OK or the hot-water control named by the display and let the operation finish. Do not interrupt the pump as the first bursts become a steady flow.

When to stop checking De’Longhi Coffee machine

  • Stop if the pump runs without any water after the permitted priming attempt, water leaks beneath the machine, or the message immediately returns with a full, correctly seated tank. Arrange De'Longhi service.
