Cleaning And Maintenance; Troubleshooting - Bosch TWK 7902 Instruction Manual

N.B.: Only operate the kettle with the lid 2
closed and the limescale filter 5 inserted,
otherwise the kettle will not switch off.
For physical reasons, the base 6 may
collect some condensation water. This is
normal; it does not mean that the kettle 1
leaks.
After boiling, let the kettle cool down for
5 minutes before refilling it with water.
Do not turn on the appliance if the kettle 1
is empty, otherwise the overheat control will
engage and the appliance will switch itself
off automatically.
