How to run a Deep clean cycle
The monthly Deep clean cycle removes limescale from your machine's water system. Your machine's LCD screen will let you know when it's time. You'll need 150g of citric acid, then follow the steps in our video guide or user manual.
The service includes labour and spare parts where required (excluding additional accessories and filters), which are guaranteed for 12 months or until service support ends for your machine – whichever is soonest.
