Gaggia cadorna

The Cadorna is designed for the INTENZA+ water filter. Before installation, immerse the cartridge vertically in cold water with its opening upwards and gently squeeze its sides to release trapped air.

Set the filter to match the measured water hardness, install it in the tank and then select CLEAN/SETTING → SETTINGS → WATER FILTER to activate it. When the filter expires, the Cadorna displays “Filter expired, replace or disable it”. Select REPLACE after installing a new cartridge, or DISABLE if the machine is being used without one.

1. Switch the Cadorna off and disconnect the power cord.
   
2. Remove the coffee pucks container and open the service door.
   
3. Remove the coffee residues drawer.
   
4. Press the PUSH lever on the brew group while pulling the brew group's handle to remove it.
   
5. Rinse the brew group thoroughly using lukewarm water, paying particular attention to coffee residue around the filters and moving parts.
   
6. Allow the brew group to air dry before putting it back into the machine.
   
7. Before refitting it, make sure the brew group is in its correct resting position. The lever should be in contact with the base of the group and the locking hook should be correctly positioned.
   
8. Slide the brew group back into the machine until it locks into position.
   
9. Refit the coffee residues drawer and coffee pucks container, then close the service door.
   

Important: Do not put the Cadorna brew group in a dishwasher and do not use washing-up liquid or other detergents on it. The manual warns that these can cause the brew group to malfunction and can affect the flavour of the coffee.

The brew group also requires periodic lubrication. The manual specifies approximately every 4 months for 1–5 drinks per day, every 2 months for 6–10 drinks per day, and monthly for more than 10 drinks per day.

1. Allow the steam system to cool before handling the components.
   
2. Remove the Classic Pannarello from the steam spout.
   
3. Remove the rubber handle from the steam spout.
   
4. Rinse both removable components thoroughly under running water.
   
5. Wipe the exposed steam wand with a clean damp cloth, removing any remaining milk residue.
   
6. Refit the rubber handle.
   
7. Reassemble the Classic Pannarello correctly onto the steam wand before using the steam function again.
   

The Cadorna troubleshooting guide specifically identifies a dirty or incorrectly assembled Classic Pannarello as a possible cause of poor milk frothing.

1. Remove the old filter from the water tank. If installing a filter for the first time, remove the small white filter from the tank and store it somewhere dry.
   
2. Immerse the new INTENZA+ filter vertically in cold water, keeping its opening pointing upwards.
   
3. Gently squeeze the sides of the cartridge to release trapped air bubbles.
   
4. Set the adjustment on the bottom of the filter according to your measured water hardness:
   
   
   A – soft water, 1–2 red squares
   
   
   B – hard water, 3 red squares
   
   
   C – very hard water, 4 red squares
   
   
   
5. 
   Push the prepared INTENZA+ filter securely into its position in the water tank.
   
6. Fill the water tank with fresh water and reinstall it in the Cadorna.
   
7. Press CLEAN/SETTING on the control panel.
   
8. Select SETTINGS.
   
9. Select WATER FILTER.
   
10. If replacing an expired cartridge, select REPLACE and confirm the selection.
    
11. Follow the instructions shown on the Cadorna's display to complete activation of the new filter.
    

If you decide to operate the machine without an INTENZA+ filter, select DISABLE instead. The Cadorna displays “Filter expired, replace or disable it” when the registered filter reaches the end of its service period.

1. Remove the Classic Pannarello from the steam wand.
   
2. Press the CLEAN/SETTING button.
   
3. Select CLEAN on the display.
   
4. Select DESCALING and then press START/STOP.
   
5. Remove the drip tray and coffee pucks container, empty them and reinstall them.
   
6. Remove and empty the water tank.
   
7. If an INTENZA+ water filter is installed, remove it from the tank.
   
8. Pour the entire bottle of the specified descaling solution into the water tank.
   
9. Add water up to the tank's CALC CLEAN mark and reinstall the tank.
   
10. Place a container of at least 1.5 litres beneath both the steam tube and coffee dispensing spout.
    
11. Follow the instructions shown on the Cadorna's display to begin the descaling procedure.
    
12. Allow the machine to complete the process. The full programme takes approximately 25 minutes and includes both the descaling and rinsing stages, with liquid dispensed at intervals.
    
13. Once the descaling stage has finished, rinse the water tank and allow the machine to rinse its internal water circuit by following the instructions on the display.
    
14. When the complete procedure has finished, reinstall the INTENZA+ filter in the water tank.
    

You can pause and resume the programme using START/STOP. Do not remove the brew group while descaling is in progress; wait until the complete procedure has finished.
