Cleaning stage 5:
MAIN WASH 2
Parameter [r45] = 0
‘Cleaning stage 5’ disabled
Parameter [r45] = 1..5
‘Cleaning stage 5’ execute one time
In case of cleaning method 'green'
– it is set in programme step [n30] how often
the feed container is filled with water up to level 2 and water is pumped backup to
level 1. The drain valve remains closed up to cleaning step [n55/n56].
Settings for version 6.1.4 (dosing in pre-hopper)
Parameter [r20 = 0] and parameter [n50 = min. 2] since the detergent is added
when water is taken from the pre-hopper for the second time.
Water is taken in.
Parameter [n51] is used to stipulate whether water will be taken by level or time.
If time-controlled, the water intake time is defined in parameter [n52].
If, in the event of intake by level, the level is not reached after a pre-set time [r32],
the cleaning cycle is interrupted. See section 7.5.3
- F44
The cleaning parameter [r54] is used to stipulate whether cold, hot or mixed water
is to be taken in.
Agitator and pump start to run. Water circulates in the tank.
Another option is to select an 'additional water intake time' using [n53].
Depending on the setting of the parameter [r20], acidic detergent is injected at the
end of the water intake time [n52] or the subsequent water intake time [n53]. The
duration of the detergent dosing is set in parameter [n102].
If a heater is present [r35], this is switched on. When the heating temperature
[n107] is reached, the heater is switched off again.
If the temperature is not reached within the pre-set time [r37], the control unit con-
tinues with the program, but a fault report is displayed at the end. See section 7.5.3
- F44
If a switch-on delay [r36] has been parameterized for heating, heating starts only
after this time has elapsed. (This is to ensure that water is in the heater.)
In case of green
n53 have to be
parameterized on „0“
In case of green
n51 and n52 have to be
parameterized on „0“
