  If you encounter a turbidity sensor wiper motor error, it indicates that the turbidity sensor wiper is not operating. First, press the ESC key and check for any obstacles near the wiper. Then, attempt the measurement again. If the error continues, the motor likely needs replacement, and you should contact your nearest sales outlet to have the sensor probe repaired.

  If you receive a Probe EEPROM error, it is due to an internal IC failure. First, press the ESC key and redo the operation. If the error persists, turn the power OFF, then restart the system (note that the current data will not be saved). If the error continues, contact your nearest sales outlet to have the display repaired.

  If you encounter a turbidity sensor light source error, it means there is a failure with the turbidity sensor light source. Turn the power OFF, then wipe off any water droplets on the probe. Remove the turbidity sensor and check for water droplets around the turbidity sensor connector, then mount the sensor again. If the error persists, replace the turbidity sensor.
