Older Faema double head. Power light on,...

It is on the right side of the machine behind the grouphead if you remove the top panel you will see te box with the red switch sticking out. MAKE SURE THERE IS WATER IN THE MACHINE FIRST!!!!!! Do not trust the sight glass, if the level probe is in there, turn machine to 1 then disconnect the electrical connector on the side of the sight glass, the pump should kick in and water will flow in the boiler, if the level does not increase in the glass, then the machine turned itself off because the element got too hot from lack of water. The hole for the sight glass is blocked.
