In these devices, the fluid flow is controlled by a block consisting of four solenoid valves. If only one solenoid coil or the valve interior is defective, it can be replaced individually. However, if the valve body is defective, often due to a crack, the entire block must be replaced. When purchasing the replacement part, pay attention to the exact designation, as there are different versions.
The instructions can also help with devices from Philips and Gaggia—the devices are all from the same manufacturer and are very similar in design.
