Puly Caff Plus Care Set: Siebträger Maintenance Routine

Quick answer

Use the Puly Caff Plus Care Set once a week for a full backflush and portafilter soak, and rinse the group head daily. This routine removes coffee oils and milk residues before they turn rancid and affect flavor.

Weekly cleaning steps with Puly Caff Plus Care Set

1. Flush the group head with water: Before applying detergent, run a short water flush through the group head with the portafilter removed to loosen loose grounds. Use a blind filter basket in the portafilter for backflushing later. Skipping this step can leave grit that scratches the shower screen during backflushing.
2. Load the portafilter with detergent: Add the recommended amount of Puly Caff Plus powder to the blind filter basket. Consult the product label for the correct dose; do not guess. Insert the portafilter into the group head. Using too much detergent can leave residue that affects the next shot; using too little reduces cleaning power.
3. Run the backflush cycle: Start the pump for about 10 seconds, then stop for 10 seconds, and repeat this cycle 5 to 6 times. This forces the detergent solution through the group head and solenoid valve. Follow your machine manufacturer's backflush procedure if it differs. Do not run the pump continuously for long periods; short bursts are safer for the pump and more effective at dislodging residue.
4. Rinse thoroughly with clean water: Remove the portafilter, empty the blind basket, and reinsert it. Run several backflush cycles with clean water only to flush out all detergent. Then remove the blind basket and run a final water flush through the group head. A single rinse is not enough; residual detergent can make espresso taste soapy. Rinse until the water runs clear and odor-free.
5. Soak the portafilter and basket: Dissolve a small amount of Puly Caff Plus in warm water in a bowl. Soak the portafilter, filter basket, and shower screen (if removable) for 10 to 15 minutes. Do not soak the handle if it is wooden or painted, as detergent may damage the finish. Soaking only the metal parts prevents damage to handle materials and keeps the detergent from drying out rubber gaskets.
6. Scrub and rinse the soaked parts: Use a soft brush or sponge to remove loosened residue from the basket and portafilter. Rinse all parts thoroughly under running water until no detergent remains. Reassemble the machine. A soft brush protects the basket's holes and surface; never use abrasive pads that can scratch metal.
7. Flush and pull a test shot: Run a final water flush through the group head. Pull a test shot and discard it to ensure no detergent residue remains. If the shot tastes soapy or bitter, repeat the rinse cycle. Discarding the first shot after cleaning is a simple safeguard against detergent residue in your coffee.
