If the milk foam quality dispensed from a CS220 is poor, which of the following is likely to be the cause?
- A.
Cold milk (approximately 40-50F) stored inside of the canister.
- B.
The disposable straw is worn or not fixated properly.
- C.
Cold water stored in the water tank.
- D.
UHT or pasturized milk in thermal canister.
Correct Answer
B. The disposable straw is worn or not fixated properly.Explanation
If the milk foam quality dispensed from a CS220 is poor, the likely cause is that the disposable straw is worn or not fixated properly. This is because the straw is responsible for drawing in the milk and creating the foam. If it is worn or not fixed properly, it may not be able to effectively draw in the milk, resulting in poor foam quality. Cold milk, cold water, or the type of milk (UHT or pasteurized) stored in the canister would not directly affect the foam quality.Rate this question:

Turn direct water knob (valve) located on the back of the machine to OFF.
- D.
Disconnect water line connection from the rear of the machine.
Correct Answer
C. Turn direct water knob (valve) located on the back of the machine to OFF.Explanation
The correct answer is to turn the direct water knob (valve) located on the back of the machine to OFF. This step is necessary to stop the flow of water from the direct water source into the CS200 or CS220 machine. By turning off the valve, the water supply is effectively shut off, allowing for safe descaling without any water flow.Rate this question:

What would trigger the error message "Capsule not ejected - call service center" on the GEMINI PRO models?
- A.
IR light barrier under the brew unit.
- B.
Safety lid micro switch.
- C.
Extraction unit DC motor.
- D.
Capsule container micro switch.
Correct Answer
A. IR light barrier under the brew unit.Explanation
The error message "Capsule not ejected - call service center" on the GEMINI PRO models would be triggered by the IR light barrier under the brew unit. This means that if the IR light barrier is not functioning properly or is blocked, the machine will not be able to detect whether the capsule has been ejected or not, resulting in the error message. The other options mentioned, such as the safety lid micro switch, extraction unit DC motor, and capsule container micro switch, are not directly related to the ejection of the capsule and would not cause this specific error message.Rate this question:

During the descaling process on the Gemini Pro CS220, which of the following is correct regarding the appropriate water tank measurements?Hint: total water tank volume for each tank is 3L.
- A.
Right water tank contains 2L of water/200ml of descale agent; Left water tank contains 1L of water/400 ml of descale agent.
- B.
Left water tank contains 2L of water/400ml of descale agent; Right water tank contains 1L of water/200ml of descale agent.
- C.
Both water tanks have an equal measurement of water and descaling agent.
- D.
Right water tank contains 3L of water/600ml of descale agent; Left water tank contains 2L of water/400 ml of descale agent.
Correct Answer
B. Left water tank contains 2L of water/400ml of descale agent; Right water tank contains 1L of water/200ml of descale agent.Explanation
The correct answer states that the left water tank contains 2L of water and 400ml of descale agent, while the right water tank contains 1L of water and 200ml of descale agent. This is the appropriate measurement for the descaling process on the Gemini Pro CS220, as the total water tank volume for each tank is 3L. The answer option ensures that the total volume of water and descale agent in each tank adds up to the total capacity of the tank.Rate this question:

Upon bench testing a new GEMINI CS220, what suggested step should be performed to properly prime the fluid system?
- A.
Descale machine.
- B.
Fill the water tanks with hot water and cycle through fluid line to correct sticking pump/solenoids.
- C.
Run machine without any fluid to dry out the water lines.
Correct Answer
B. Fill the water tanks with hot water and cycle through fluid line to correct sticking pump/solenoids.Explanation
To properly prime the fluid system of the new GEMINI CS220, it is suggested to fill the water tanks with hot water and cycle it through the fluid line. This step helps to correct any sticking pump or solenoids, ensuring that the fluid system is functioning properly. Running the machine without any fluid would not address the issue of sticking pump/solenoids, and descaling the machine is not mentioned as a step for priming the fluid system.Rate this question:

Upon calibrating a GEMINI CS220 for installation, which setting must be changed from the default manufacturer's setting?
- A.
Coffee Temperature set to HIGH
- B.
Language changed to SPANISH
- C.
Auto-Off set to 12 hours
- D.
Filter turned ON
Correct Answer
A. Coffee Temperature set to HIGHExplanation
The correct answer is "Coffee Temperature set to HIGH". When calibrating a GEMINI CS220 for installation, the default manufacturer's setting for the coffee temperature needs to be changed to HIGH. This adjustment ensures that the coffee is brewed at a higher temperature, resulting in a hotter cup of coffee.Rate this question:

When a thermal cutoff (TCO) fuse has been fused, which part must be replaced along with the defective fuse at all times?
- A.
Heat sensor
- B.
Logic board
- C.
Thermoblock
- D.
Power board
Correct Answer
A. Heat sensorExplanation
When a thermal cutoff (TCO) fuse has been fused, the heat sensor must be replaced along with the defective fuse at all times. The heat sensor is responsible for detecting excessive heat and triggering the TCO fuse to cut off the power supply. If the TCO fuse has blown, it indicates that the heat sensor has detected a high temperature and activated the fuse to prevent any potential damage or fire. Therefore, replacing the heat sensor is necessary to ensure that the system can continue to monitor and regulate the temperature effectively.Rate this question:

What is the ideal temperature of the milk as it is steamed and frothed by the Cappuccinatore of the GEMINI CS220?
- A.
120F (+/- 5)
- B.
155F (+/- 5)
- C.
175F (+/- 5)
- D.
200 (+/- 5)
Correct Answer
B. 155F (+/- 5)Explanation
The ideal temperature of the milk as it is steamed and frothed by the Cappuccinatore of the GEMINI CS220 is 155F (+/- 5). This temperature range ensures that the milk is heated enough to create a creamy and frothy texture, but not too hot that it burns or loses its flavor. The +/- 5 indicates a small margin of error, allowing for slight variations in temperature while still maintaining the desired result.Rate this question:
