If the guage no longer works it neeeds to be replaced. It is important as it shows both the pump pressure and boiler pressure.
It is essential to know the pump pressure in order to set the coffee grind, ie pressure when extracting should be approx. 9 bars and boiler pressure is set at 3 bars.
This is an inexpensive fix, easy to do and should be replaced if it gets damaged.
Turn off mains pressure - take care to install when machine is cold.
We take no responsibility for installation - if unsure on how to install contact your local service technician.
