What to do if the display is blank on my Alfa Laval Mini ECO?

If the display on your Alfa Laval Water Heater is blank, it could be due to a few reasons. First, check that the power supply cable of the connection box is properly connected. Another possibility is that the control panel isn't connected to the correct terminals of the connection box. Also, if the power supply or communication link has been interrupted for more than 8 hours, check the power cable. After power is restored, you may need to adjust the time and day.
