This original pressure switch is for Ascaso machines and is Factory set at 1.5 bar.
Pressurestats can be thought of as switches activated by pressure, which are adjustable and usually set at approximately 1.2 bars. When the pressure reaches the predetermined level (approximately 0.8 bars) the pressure stat cuts off, as such, it turns off the element. It will then turn on the element when the pressure drops again.
This part needs to be replaced if:
- Boiler is overheating - steam coming from overpressure valve
- Coffee is burnt
- Water is not hot enough for steam or coffee.
Pressurestats can get blocked over time, with mineral buildup inside the valve which causes it to be less accurate or malfunction.
