5.13 Power failure during grinding
If the power fails during grinding, grinding will be interrupted. All parameters are retained, and
the remaining grinding time is saved. When the device is switched on again, a corresponding
message appears in the display.
You can continue the process by pressing the START button. The automatic saving of the
remaining grinding time means the grinding then continues until the end of the originally set
grinding time.
For safety reasons the device must be opened and the grinding chamber inspected. Grinding
then continues automatically when the lid is closed.
The process is aborted by pressing the STOP button. .
