Descaling
In hard water areas limescale can build up within the appliance after prolonged use. For best taste and
extended appliance life, descale it regularly. Installation of a water filtration system is also recommended.
BUFFALO recommend descaling your unit every 3 months or more frequently. To descale the appliance:
1. Pour a solution of descaler and water into the reservoir.
Use a suitable descaler and follow the manufacturer’s instructions on the
container.
2. Turn the main switch On and Press the brewing button.
3. After approximately 4 minutes turn the appliance Off to allow the descaling solution to work through
the system.
4. After approximately 10 minutes turn the appliance back On. Allow the reservoir to empty.
5. Discard the solution collected in the jug.
6. Fill the reservoir with clean water and turn the appliance back On to flush out the system and remove
any descaler residue. Discard the collected water and rinse the jug. Repeat with clean water 2 more
times to flush out.
7. The appliance is now ready for use.
