GROUP HEAD BACK FLUSH

**Best practice: **After making coffee, always purge some water from the group head, this will remove any coffee residue in your group shower and help maintain correct and clean water flow. This should be part of your daily ritual to ensure you get the best tasting coffee everyday!

To remove built up coffee residue and oils from the coffee it is recommended to use a group head backflush detergent after every kilogram or monthly (whichever comes first).
