E08 — Flow Switch Abnormality / Low Water Flow

What does E08 mean?

This error occurs if no water flow signal is detected after the water pump operates for 120 seconds, or if the water flow is lower than the set value. It can be caused by issues like crystallization on the pump rotor, especially after extended shutdown or with poor water quality.

• Crystallization or debris on the water pump rotor preventing startup.
• Low water pressure or insufficient water in the system.
• A faulty flow switch or flow sensor.
• A blocked water circuit.
