If the gauge no longer works - it needs 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 2-3 bars.
This is an inexpensive fix, easy to do, and should be replaced if it gets damaged.
Turn off the mains pressure - take care to install it when the machine is cold.
We take no responsibility for installation - if unsure of how to install contact your local service technician.
Specifications:
Double scale pump and boiler pressure: 0 ÷ 2.5 / 0 ÷ 16 bar
