Why is my Heatrae Sadia Multipoint ECO 30L H water not heating?

  Several factors can cause this. It could be an electrical supply fault, so check the electrical supply. The thermal cut out might have tripped; in this case, check for error code E2, reset it if it has operated, and inspect the thermostat, replacing it if necessary. The thermostat setting might be too low or faulty, so verify the program/settings and adjust as needed. Finally, the element might have failed, requiring replacement of the immersion heater.

  First, check that the inlet and outlet connections are correctly installed and that the valves are installed according to the flow direction marks. Next, ensure the mains water supply is turned on. Finally, inspect the mains water supply for any obstructions and check the strainer in the pressure reducing valve.

Why is my Heatrae Sadia Multipoint ECO 30L H continuously discharging water from the expansion relief valve?

  This could be due to excessive mains water pressure. Check the pressure from the pressure reducing valve and replace it if it exceeds 0.35MPa (3.5bar / 51psi). Alternatively, the expansion relief valve itself might be faulty and need replacement.
