ILLY Espresso Machine Descaling Instructions

Keep your illy espresso machine running at its best with regular descaling.

Step 1: Prepare the Descaling Solution

• Mix 16 oz of water with descaler.
• If using citric acid: mix 1 oz of citric acid with 16 oz of water.
• Important: Premix the solution in a separate container before adding it to the machine.
• Water should be warm (not hot).

Step 2: Fill the Water Tank

Pour the prepared solution into the machine’s water tank.

Step 3: Start the Machine

Turn the machine on and allow it to fully heat up.

Step 4: Run Solution Through the Machine

Once ready, run 3–4 oz of the solution through the group head.

Step 5: Soak Cycle

Turn the machine off and let it sit for 20 minutes.

Step 6: Repeat Process

Turn the machine back on, run another 3–4 oz, then turn off and let sit for 20 minutes.

Repeat this cycle until the water tank is empty.

Step 7: Rinse the Machine

• Rinse the water tank thoroughly.
• Fill the tank with fresh water.

Step 8: Flush with Clean Water

• Run 1–2 full tanks of clean water through the machine.
• No need to pause — just continue flushing until complete.
