1- Check water pressure in
heater installation of your
boiler.
2- Fill the system with water
until the pressure reaches
1.5-2 bar (device will eliminate
error when the pressure is over
0,8 bar).
3- Check your valves and
installation against leaks.

present (or persists), notify
gas safe engineer.
1- Press reset button.
2- If the error is still present (or
persists) after reset, notify gas
safe engineer.
