Display shows 'LO' or low water icon, beeping, unit will not start ice cycle even though reservoir appears to have water.

Safety first: Disconnect power before removing the water tank or internal covers.

• Verify water level: Fill the reservoir to the indicated MAX line. Some Severin models are sensitive to low levels and will show LO even if water is visible.
• Reseat the tank: If your model has a removable tank, remove and reinstall it firmly to ensure the valve at the bottom opens correctly.
• Clean level probes: If the unit uses metal probes for low water detection, clean them with a cloth and white vinegar to remove scale.
• Check float movement: For float-based systems, confirm the float moves freely and is not stuck at the low position.
• Inspect wiring: Follow the sensor or float wires to the control PCB and reseat the connector.
• Replace sensor: If LO persists despite correct water level and cleaning, replace the low water sensor or float assembly.
