Details:
This pressure switch is for Expobar Crema and coffee queen branded machines.
Pressure switches are activated by pressure, which corresponds to temperature.
When the pressure reaches the predetermined level (approximately 1 bar) 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:
- The boiler is overheating - steam venting from the 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.
