Limescale deposits not only affect the taste, but can also shorten the life and performance of your espresso machine.
ceragol ultra Premium Descaler is based on amidosulfonic acid, which is particularly gentle on materials, and is ideal for sensitive portafilter machines. It effectively removes limescale without attacking seals or metal parts. The formula even allows for hot descaling if the appliance is approved for this. This keeps the machine hygienically clean and ensures long-lasting performance.
Step-by-step Instructions for Descaling your Portafilter Machine
Descaling with ceragol ultra Premium Descaler
💧 Basic for all machine types:
100 ml Ceragol Ultra Premium Descaler + approx. 500–600 ml water
Always let the machine cool down before you start descaling
Descale brew group, steam and hot water dispensing, if possible
🔹 1. Single-circuit Portafilter Machine
Typical example: Rancilio Silvia, Lelit Anna
✅ Steps:
Switch off the machine & let it cool down.
Fill the water tank with 100 ml descaler + 500 ml water.
Switch on the machine, start the pump.
Run approx. 150–200 ml of the solution through the brew group.
Switch off the pump and let it act for 10–15 minutes.
Then let the remaining solution run through.
If necessary, open the steam valve and let some solution through.
Rinse the water tank thoroughly, fill with fresh water.
Rinse clear water several times through brew group and steam valve.
🔸 2. Dual-circuit Portafilter Machine
Typical example: ECM Mechanika, Bezzera Magica
🔥 Special Feature:
Dual-circuit machines have a heat exchanger (HX) that runs via the main boiler – direct descaling of the steam boiler is not possible without removal.
✅ Steps:
Switch off the machine & let it cool down.
Add 100 ml descaler + 500–600 ml water to the water tank.
Switch on the machine.
Start dispensing via the brew group (only the heat exchanger is descaled).
Let about 200 ml of solution run through, then pause for 10 minutes.
Repeat the process until the tank is empty.
Do not descale through the steam tap, as this is connected to the steam boiler.
Clean the water tank, fill with clear water.
Run fresh water through the brew group several times.
🔻 3. Dual Boiler Portafilter Machine
Typisches Beispiel: ECM Synchronika, Profitec Pro 700, Lelit Bianca, Rocket
🔥 Special Feature:
Two separate boilers for steam & coffee. Both can (on some models) be emptied or filled separately.
✅ Steps:
Switch off the machine & let it cool down.
If necessary, empty the boiler via drain valves (observe manufacturer’s instructions).
Add 100 ml descaler + 500–600 ml water to the tank.
Brew boiler: Start dispensing via brew group, let solution run through, with pauses.
Steam boiler: Briefly open steam dispensing, let solution draw in.
Let it act for 10–15 min., then dispense remaining solution.
Clean the water tank, rinse with clear water.
Run fresh water several times through both boilers (via dispensing & steam).
🕓 Recommended frequency:
- < 8°dH water hardness: descale every 6 months
- 8-16°dH water hardness: descale every 3 months
- >16°dH water hardness: descale every month
