Gaggia Aluminium Boiler

Understanding and Replacing the Aluminum Boiler in Your Gaggia Classic Machine

When to Replace the Aluminum Boiler

While the Gaggia Classic is known for its durability, the aluminum boiler may need replacement due to:

Significant limescale buildup that cannot be resolved with descaling.
Visible corrosion or damage to the boiler itself.
Consistent issues with water temperature or steam production.

Water Capacity of the Boiler

The aluminum boiler in the Gaggia Classic machine has a water capacity of approximately 120ml, designed for optimal heat up times and temperature stability, ensuring the perfect espresso shot.

How to Change the Aluminum Boiler

Step 1: Safety First

Unplug the machine and ensure it's completely cooled down before starting the replacement process to avoid any risk of injury.

Step 2: Access the Boiler

Remove the top cover of the Gaggia Classic by unscrewing the necessary screws. This will expose the internal components, including the aluminum boiler.

Step 3: Disconnect the Boiler

Carefully disconnect the wires and hoses attached to the boiler. Be sure to take a photo or note the connections to ensure correct reassembly.

Step 4: Remove the Boiler

Unscrew the boiler from its mounting and gently remove it from the machine. Handle the old boiler carefully to prevent any leakage or spillage of remaining water.

Step 5: Install the New Boiler

Position the new aluminum boiler in place and secure it with screws. Reattach the hoses and wires according to the notes or photos you took during disassembly.

Step 6: Reassemble and Test

Reassemble the machine's cover and plug in the machine. Perform a test run by heating up the machine and checking for leaks or any unusual noises. Ensure the machine reaches the correct temperature and produces steam properly.

Replacing the aluminum boiler in your Gaggia Classic machine can restore its performance and extend its lifespan. Always follow safety guidelines and consult the machine's manual or a professional if unsure about any step.
