1. Single-circuit Portafilter Machine<\/strong><\/h2>\nTypical example:<\/strong> Rancilio Silvia, Lelit Anna<\/p>\n\u2705 Steps:<\/h3>\n\n- \n
Switch off the machine & let it cool down.<\/strong><\/p>\n<\/li>\n- \n
Fill the water tank with 100 ml descaler + 500 ml water<\/strong>.<\/p>\n<\/li>\n- \n
Switch on the machine, start the pump.<\/p>\n<\/li>\n
- \n
Run approx. 150\u2013200 ml of the solution through the brew group<\/strong>.<\/p>\n<\/li>\n- \n
Switch off the pump<\/strong> and let it act for 10\u201315 minutes.<\/p>\n<\/li>\n- \n
Then let the remaining solution run through.<\/p>\n<\/li>\n
- \n
If necessary, open the steam valve and let some solution through.<\/p>\n<\/li>\n
- \n
Rinse the water tank thoroughly, fill with fresh water.<\/strong><\/p>\n<\/li>\n- \n
Rinse clear water several times through brew group and steam valve.<\/p>\n<\/li>\n<\/ol>\n
\n\ud83d\udd38 2. Dual-circuit Portafilter Machine<\/strong><\/h2>\nTypical example:<\/strong> ECM Mechanika, Bezzera Magica<\/p>\n\ud83d\udd25 Special Feature:<\/h3>\n
Dual-circuit machines have a heat exchanger (HX) that runs via the main boiler \u2013 direct descaling of the steam boiler is not possible without removal.<\/p>\n
\u2705 Steps:<\/h3>\n\n- \n
Switch off the machine & let it cool down.<\/strong><\/p>\n<\/li>\n- \n
Add 100 ml descaler + 500\u2013600 ml water<\/strong> to the water tank.<\/p>\n<\/li>\n- \n
Switch on the machine.<\/p>\n<\/li>\n
- \n
Start dispensing via the brew group<\/strong> (only the heat exchanger is descaled).<\/p>\n<\/li>\n- \n
Let about 200 ml of solution run through, then pause for 10 minutes.<\/p>\n<\/li>\n
- \n
Repeat the process until the tank is empty.<\/p>\n<\/li>\n
- \n
Do not descale through the steam tap<\/strong>, as this is connected to the steam boiler.<\/p>\n<\/li>\n- \n
Clean the water tank, fill with clear water.<\/p>\n<\/li>\n
- \n
Run fresh water through the brew group several times.<\/p>\n<\/li>\n<\/ol>\n
\n\ud83d\udd3b 3. Dual Boiler Portafilter Machine<\/strong><\/h2>\nTypisches Beispiel:<\/strong> ECM Synchronika, Profitec Pro 700, Lelit Bianca, Rocket<\/p>\n\ud83d\udd25 Special Feature:<\/h3>\n
Two separate boilers for steam & coffee. Both can (on some models) be emptied or filled separately. <\/p>\n
\u2705 Steps:<\/h3>\n\n- \n
Switch off the machine & let it cool down.<\/strong><\/p>\n<\/li>\n- \n
If necessary, empty the boiler via drain valves (observe manufacturer’s instructions).<\/p>\n<\/li>\n
- \n
Add 100 ml descaler + 500\u2013600 ml water<\/strong> to the tank.<\/p>\n<\/li>\n- \n
Brew boiler: Start dispensing via brew group, let solution run through, with pauses.<\/p>\n<\/li>\n
- \n
Steam boiler: Briefly open steam dispensing, let solution draw in.<\/p>\n<\/li>\n
- \n
Let it act for 10\u201315 min., then dispense remaining solution. <\/p>\n<\/li>\n
- \n
Clean the water tank, rinse with clear water.<\/p>\n<\/li>\n
- \n
Run fresh water several times through both boilers (via dispensing & steam).<\/p>\n<\/li>\n<\/ol>\n
