Setup
- Unpacking: Carefully remove all components from the packaging.
- Initial Cleaning: Before first use, disassemble the Moka Pot and wash all parts (water chamber, filter funnel, collector) with warm water and mild soap. Rinse thoroughly to remove any manufacturing residues.
- First Brew (Seasoning): To season the Moka Pot and remove any metallic taste, brew coffee 2-3 times and discard the coffee. This process helps to build up a protective layer inside the pot, enhancing future coffee flavor.
Operating Instructions
- Fill Water Chamber: Unscrew the top part from the base. Fill the lower chamber with cold water up to the level of the safety valve. Do not exceed the valve.
- Add Ground Coffee: Insert the filter funnel into the lower chamber. Fill the funnel with medium-fine ground coffee. Do not tamp the coffee. Level the grounds gently.
- Assemble and Heat: Screw the upper part firmly onto the base. Place the Moka Pot on a stovetop burner over medium heat. Ensure the flame does not extend beyond the base of the pot.
- Brewing: As the water heats, pressure builds, forcing water through the coffee grounds and into the upper chamber. You will hear a gurgling sound as the coffee brews. Once the upper chamber is full and the gurgling stops, remove the Moka Pot from the heat immediately.
- Serve: Pour the freshly brewed coffee into cups and enjoy.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your Bialetti Moka Pot.
- Cleaning: After each use, disassemble the Moka Pot and rinse all parts with warm water. Do not use soap or detergents, as they can leave residues that affect coffee flavor and damage the aluminum.
- Drying: Dry all components thoroughly before reassembling and storing to prevent oxidation and mineral buildup.
- Dishwasher Safety: This Moka Pot is not dishwasher safe. Hand wash only.
- Gasket and Filter Replacement: Periodically check the rubber gasket and filter plate for wear. Replace them if they appear damaged or if you notice steam escaping during brewing.
Troubleshooting
- Coffee not brewing or brewing slowly: Ensure the water level is below the safety valve and the coffee grounds are not tamped too tightly. Check for blockages in the filter or spout.
- Weak or watery coffee: Use fresh, medium-fine ground coffee. Ensure the filter funnel is completely filled. Avoid using too much water.
- Steam escaping from the side: Ensure the upper and lower chambers are screwed together tightly. Check if the rubber gasket is properly seated and not worn out.
- Metallic taste: Perform the initial seasoning process again. Ensure no soap residue remains after cleaning.
