- 9.A NESPRESSO machine is experiencing a reduced extraction flow. The equipment has been descaled and the pump has been replaced, but the extraction flow rate remains low. What part would typically be the cause of this malfunction and can be cleaned and reused?
- A.
Steam outlet nozzle
- B.
Pump fluid connect elbow
- C.
Solenoid valve
- D.
Thermoblock
- 10.On a CS220 GEMINI PRO, the steam function is chosen. Rather than steam exiting the steam outlet the solenoid positioned at the exit point of the thermoblock is clogged resulting in excessive pressure build up causing a steam tube to break. As there is a secondary solenoid built into the steam line for the purpose of releasing any remaining steam pressure into the lower drip tray, why would the machine logic not open the secondary solenoid to prevent excess pressure and damages?
- A.
The thermoblock heat sensor is defective.
- B.
The thermoblock heat sensor did not reach critical levels.
- C.
The equipment's program is incapable of measuring pressure build up to prevent damages.
- D.
The logic board is defective.
- 11.On a GEMINI PRO CS model, why would the machine prompt the user on the display to "Push A Button"?
- A.
To test visibility of water tank magnet sensors.
- B.
To test that a button on the keypad functions.
- C.
To test pump reaction.
- D.
To test that the flow meter functions.
- 12.On a GEMINI PRO CS model, why would the error message "Machine Blocked - Call Service Center" appear following the message "Push A Button" after attempting to push a button one (1) or more times?
- A.
The power or logic board is defective.
- B.
The flow meter is defective and does not send feedback as water passes through.
- C.
The pump thermostat is overheating and must be allowed to cool down.
- D.
The solenoid is defective and does not allow the electronics to control it during water cycling.
- 13.On a GEMINI PRO CS model, when the error message "Machine Blocked - Call Service Center" appears followed by the message "Heating Up", which of the following explanations is not the cause of this error?
- A.
The safety lid detected a block in the brew unit.
- B.
Thermoblock has malfunctioned.
- C.
Heat sensor has malfunctioned.
- D.
Thermal cut off fuses are burned.
- 14.On a GEMINI model CS100, CS200 or CS220, what are two possible reasons for an increase of water volume inside the capsule container?
- A.
The steam valve is clogged causing water to exit into the capsule container.
- B.
The large seal found in the shower head assembly of the upper brew chamber is worn or damaged.
- C.
The upper seal found in the shower head assembly of the upper brew chamber is damaged.
- D.
The solenoid(s) responsible for draining the excess fluid line into the drip tray is open.
