11.6 Level control setting
The level control is pre-
set in the factory to “average” water quality. Depending on
the hardness of the local water supply, sensitivity can be adjusted as follows:
Setting under the I/O test parameters:
In the level “I/O test parameters” (see section 8.12), open the water intake relay
until the level is reached. (Visual check of electrode)
Setting level 1: Select parameter [o.41].
Press and hold down SET - simultaneously set the displayed value to "-10" using
the DOWN ARROW button.
Keep the SET key pressed - simultaneously increase the value slowly with the UP
ARROW button until the green LED is lit (and then increase by 1). Releasing the
SET button saves the last set value.
Setting level 2: Select parameter [o.42] -> then see level 1
Fine adjustment during cleaning
(only for the service technician)
This method works only when sensitivity has been set too low!
If at the start of the first washing stage (water intake until level is reached) no water
is detected despite the level electrode having been reached, water continues to en-
ter. The service technician can now adjust the sensitivity setting:
Hold down the SET button for 4 seconds: The water valve is switched off.
The value indicated changes from the programme stage display to level sensitivity
display. The value last set appears.
Use the DOWN ARROW to adjust the value shown to “-10".
Use the UP ARROW button to increase the value slowly until the green LED lit up.
(And then increase by 1).
Pressing CLEANING button. The value set is stored, and washing continues from
the appropriate stage.
Fine adjustment in the extended washing parameters
(Only for the service technician)
The level input sensitivity can be further adjusted manually using parameters [r30]
for level 1 and [r31] for level 2.
11.7 Relay function 'set level 2 to relay'
If this function '23' is assigned to a relay [A1..A20], the relay is always energized
when water is detected at the level 2 input.
