Quick Answer
Use Puly Caff Descaler to safely remove scale from your espresso machine without damaging plastics, silicone, or aluminium parts. Follow the steps below for a thorough descale.
Why Choose Puly Caff Descaler
Puly Caff Descaler is a liquid formula designed specifically for domestic and small coffee brewers. It is safe for all plastics, silicone, aluminium, and traditional materials, making it a versatile choice for most espresso machines. It is the only descaler recommended by Lelit for their machines, so you can trust it won't harm internal components.
How to Descale Your Espresso Machine
- Prepare the Machine: Turn off and unplug your espresso machine. Remove the water tank and empty it. Take out any water filters. Common mistake: forgetting to remove water filters. They can absorb the descaler and become unusable.
- Mix the Descaler Solution: Follow the ratio on the Puly Caff packaging (typically one sachet per liter of water). Pour the solution into the water tank and reattach it. Checkpoint: Use the correct concentration. Too weak won't remove scale; too strong may cause foaming.
- Run the Descale Cycle: Plug in the machine and turn it on. Run the solution through the group head and steam wand as if brewing, collecting the output in a container. Stop when the tank is nearly empty. Common mistake: letting the tank run completely dry. This can introduce air into the pump and cause damage.
- Let the Solution Sit: Wait 15-20 minutes after running the solution through. This allows the descaler to break down any stubborn scale inside the boiler and pipes. Checkpoint: Do not leave the solution sitting longer than recommended, as it may affect seals over time.
- Rinse Thoroughly: Empty the tank and refill with fresh water. Run two full tanks of fresh water through the machine to flush out all descaler residue. Common mistake: Not rinsing enough. Residual descaler can affect the taste of your espresso and may irritate your stomach.
- Final Check: Brew a test shot of coffee and discard it. Your machine is now descaled and ready for use. Empty
