Does anyone know how to restart the timer on a (1997) Rayburn 400K?

Tank ran out of oil yesterday. Have refilled tank and bled air and water from inlet pipes then pressed reboot - fan comes on fine but clock/timer showing blank and only shows E for error when press "+" on timer. Otherwise no sign of life with the timer. Timer needs be on for operating the Rayburn. Instructions don't cover at all.
