Turbidity Sensor
The turbidity sensor function is only activated in cycles “AUTO
65° and AUTO BIO 50°”.
Function:
The input voltage with the turbidity sensor may be between 6 V and 11.4 V. (The measurements are
described in detail in the chapter “Measuring Points at the Electronic Control (in the base)”). For a clear
water the output voltage must always be 4.3 V. If that value differs due to soiling of the turbidity sensor
after a longer operational period, the Easytronic plus recontrols the input voltage with the turbidity sensor
automatically until the output voltage is 4.3 V. This happens during the final rinse cycle. If the 4.3 V is not
achieved within 8 seconds, the fault “C5” is stored in the fault memory. If the output voltage falls below 3
V in the prewash cycle and below 3.8 V in the intermediate rinsing cycle, turbid water will be detected.
With the service test routine the turbidity sensor will be calibrated to 3.5 V not with water but with air.
That corresponds to 4.3 V with water.
