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 2 weeks or more frequently in case of heavy uses. 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
descaler’s container.
2. Turn the power switch for brewing On.
3. After the solution begins to drop into the jug, turn the appliance Off.
4. Wait 5 - 6 minutes to let the solution dissolve the deposits inside. Then turn the appliance back On.
5. After the entire solution has worked through the system, turn the appliance Off.
6. Discard the solution collected in the jug.
7. 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.
8. Drain the water completely using the drain screw at the back.
9. The appliance is now ready again for use.
