  If the Harvia Control Unit displays error E9, it indicates a connection failure or low water level. First, turn off the power and inspect the data and sensor cables and their connections, then turn the power back on. Also, if the water level warning light is blinking, add water (for manual filling models) or check the water supply (for automatic filling models). Finally, check the steamer’s overheat protector. Consult the steamer’s or Combi heater’s manual for detailed instructions and safety information.
