4.3.2

Emptying, internal machine rinsing

When the machine is switched off, the number of baskets washed is displayed for
around 5 seconds.

Two horizontal dashes "--” are then shown in the display for 3 minutes. At this
point, the machine is still live and emptying and internal rinse cleaning must start
within this period. The machine then switches off automatically.

There are various options for storing the removable parts when the machine has
been cleaned. It is important that the level pipe sleeve is not damaged, and the
basket conveyor has a holder for this.
