Frequently Asked Questions - Viva Prestige RI8437 GAGGIA

How to make coffee with ground coffee?
Use the ground coffee filter in the pressurized filter holder. Fill with 1-1.5 measures per cup, tamp lightly, then attach and turn the knob to coffee position. Stop dispensing once the desired amount is reached.
How to use coffee pods?
Remove the ground coffee filter, insert the adapter and pod filter into the filter holder. Place a paper pod, attach, then dispense as for ground coffee. Clean the adapter after each use.
How to froth milk with the Pannarello?
Place the cold milk pitcher (1/3 full) under the Pannarello. Select steam mode, wait for the steam indicator to light up, then open the steam knob. Gently move the pitcher to create foam. Close and rinse the Pannarello.
What to do if the pump is very noisy?
This noise indicates a lack of water in the tank or incorrect positioning. Fill the tank with fresh water and ensure it is properly engaged. If necessary, prime the circuit by dispensing water through the Pannarello.
How to descale the machine?
Use only Gaggia descaling solution. Follow the detailed procedure in the manual: pour the solution into the tank, dispense several cups of water, let it sit for 15-20 minutes, then rinse thoroughly with fresh water.
Coffee leaks around the edge of the filter holder, what to do?
Check that the filter holder is correctly attached and its top edge is clean. Make sure the pod or ground coffee does not exceed the edge. If necessary, reduce the amount of coffee.
How to clean the classic Pannarello?
After each use, remove the Pannarello, take off the plastic handle, rinse with fresh water. Clean the steam nozzle with a damp cloth, then reassemble.
The machine does not dispense coffee or very little, why?
Possible causes: the hot water/steam knob is open, scale has accumulated, the filter is clogged, the grind is too fine or tamped too hard, or the pod is not suitable. Clean the filter, descale, or adjust the grind.
What is the first installation procedure?
Remove the packaging, place the machine on a stable surface with 15 cm clearance around. Fill the tank with fresh water. Prime the circuit by dispensing water through the Pannarello, then perform a manual rinse cycle.
How to turn off the machine and save energy?
The main switch is at the back. The machine automatically enters energy-saving mode after 30 minutes of inactivity. To turn it back on, press the main switch.

How to descale the GAGGIA Viva Prestige RI8437 coffee machine?
Frequently Asked Questions - 05/04/2026
Response Notice-Facile

Descaling your GAGGIA Viva Prestige RI8437 coffee machine is an essential procedure that should be performed regularly (every 2 to 3 months depending on the hardness of your water) to maintain your machine's performance and preserve your warranty. Use exclusively the Gaggia descaling solution: any other product (vinegar, sulfuric acid, hydrochloric or acetic acid) would damage the internal water circuit and invalidate your warranty. Similarly, the absence of regular descaling automatically voids your warranty.

Step 1: Preparation. Attach the pressurized filter holder to the coffee distribution group. Completely remove and empty the water tank. Pour half of the Gaggia descaling solution into the tank, then fill with fresh water up to the MAX level indication. Reinstall the tank in the machine.

Step 2: Dispensing the descaling solution. Turn the main switch to “I” to power on the machine, then turn the selection knob to the standby position. Remove the classic pannarello and place a container under the steam nozzle. Wait for the “coffee ready” light to turn on, then turn the hot water/steam knob counterclockwise and the selection knob to the coffee position to dispense two cups of water (about 150 ml each). To stop dispensing, turn the selection knob to standby and the hot water/steam knob clockwise. Turn off the machine by switching the power to “O”.

Step 3: Action of the solution. Let the descaling solution act for 15 to 20 minutes while the machine remains off. This waiting time is crucial to dissolve the limescale accumulated in the system.

Step 4: Rinsing the machine. Turn the machine back on (switch to “I”) and dispense two more cups (about 150 ml each) through the steam nozzle. Turn off the machine and wait 3 minutes. Repeat this operation (turn on, dispense two cups, turn off for 3 minutes) until the tank is completely emptied. Then rinse the water tank and fill it with fresh water up to the MAX indication. Place a container under the filter holder, turn the machine back on, and turn the selection knob to the coffee position to dispense water until the tank is empty. Turn the knob to standby.

Step 5: Final rinse through the steam nozzle. Fill the tank with fresh water up to the MAX indication. Place a large container under the steam nozzle, turn the hot water/steam knob counterclockwise, then the selection knob to the coffee position and let the machine dispense water until the tank is empty. Turn the selection knob to standby and the hot water/steam knob clockwise. Repeat the complete step 4 (rinsing through the filter holder) a second time for optimal rinsing.

Step 6: Finalization. Turn the filter holder from right to left to detach it from the distribution group and rinse it under fresh water. Fill the tank with fresh water up to MAX and reinstall the classic pannarello on the steam nozzle. Your machine is now ready for use and delivers excellent coffee again.
