3. Installation
Follow these steps to correctly install or replace the Milk Pitcher Connector:
- Preparation: Ensure your coffee machine is turned off and unplugged from the power outlet. Allow the machine to cool down if it has recently been in use.
- Locate the Old Connector: Identify the current milk pitcher connector on your machine. It is typically located on the side where the milk carafe attaches.
- Remove the Old Connector: Carefully detach the old connector. Depending on your specific model, this may involve pressing a release button or gently pulling it away from the machine. Avoid excessive force.
- Inspect the Area: Before installing the new connector, ensure the connection point on the coffee machine is clean and free from any milk residue or debris.
- Install the New Connector: Align the new De'Longhi Milk Pitcher Connector with the connection point on the machine. Push it firmly until it clicks securely into place. Ensure it is seated correctly and does not wobble.
- Visual Confirmation: Refer to the images below for visual guidance on the connector's appearance and proper attachment.

- Test Functionality: Plug the coffee machine back in and turn it on. Attach the milk carafe and perform a test cycle for milk frothing to ensure the new connector is working correctly and there are no leaks.
4. Maintenance
Regular cleaning of the Milk Pitcher Connector is essential for hygiene and to maintain optimal frothing performance. Milk residue can clog the internal channels, leading to poor frothing or blockages.
- Daily Cleaning: After each use, detach the milk carafe and the connector. Rinse the connector thoroughly under warm running water to remove any milk residue.
- Weekly Deep Cleaning: For a more thorough clean, disassemble the connector if possible (refer to your coffee machine's main manual for specific instructions on disassembling the milk system components). Soak the parts in warm water with a mild detergent or a specialized milk system cleaner. Use a small brush to clean any narrow channels. Rinse all parts thoroughly before reassembling.
- Descaling: Periodically descale your coffee machine as per its main instruction manual. While descaling primarily targets mineral buildup, a clean internal system benefits all components, including the milk frother connector.
5. Troubleshooting
If you experience issues with your milk frothing system after installing or while using the connector, consider the following:
- Poor or No Froth: This is often caused by milk residue blocking the connector's internal channels. Perform a thorough deep cleaning as described in the Maintenance section. Ensure the milk carafe is also clean.
- Leaking from Connector: Check if the connector is securely attached to the machine and the milk carafe. Inspect the O-rings on the connector for any signs of wear or damage. If damaged, the O-rings may need replacement.
- Connector Not Fitting: Double-check that you have the correct model connector (5513214821) for your specific De'Longhi ESAM series machine. Ensure there are no obstructions at the connection point on the machine.
- Unusual Noises: While some operational noise is normal, excessive or unusual noises during frothing might indicate a blockage or an improperly seated component. Clean the connector and ensure it is correctly installed.
If problems persist after following these steps, please refer to the Support & Warranty section for further assistance.
