Cleaning stage 0
: RINSE OUT
Parameter [r40] = 0
‘Cleaning stage 0’ disabled
Parameter [r40] = 1..5
‘Cleaning stage 0’ execute x-times
Water is taken in.
The parameter [r50] is used to stipulate whether cold, hot or mixed water is to be
taken in.
Furthermore, for "Cleaning stage 0", the water intake time was set [n01].
Agitator and pump start to run, the outlet valve will open.
The water circulates for the pre-set time [n02].
Agitator and pump switch off.
Drain valve opens for the pre-set time [n03]. The drain valve is assigned to the
respective cleaning stage via the parameters [r60 to r68].
Parameter [r24 / r25] determines whether the drain valve is normally open or nor-
mally closed. Applies to all cleaning stages.
