Why does Hach LPV445.99.02110 Measuring Instruments show error E-01?
- E
  Eric FloresAug 20, 2025
  Error E-01 on Hach Measuring Instruments indicates that the system detects too much ambient light. Ensure the instrument cap is fully installed over the cell holder. You can also check the service log for other error messages, inspect the cell compartment for ambient light sources, check the instrument cap for defects, and verify the light detection system is working. If needed, replace the cell compartment or detector.

  If your Hach Measuring Instruments display error E-02, it means the LED light source control on the mainboard is out of regulation. Try replacing the batteries. Also, make sure the LED in the cell holder comes on when 'read' or 'zero' is pushed. Check the service log for other error messages and inspect the LED for damage. Furthermore, check the pin contact of the LED to the mainboard.

  If your Hach Measuring Instruments display error E-20, this indicates too much signal on the light detector. Ensure the instrument cap is fully installed on the cell holder. Additionally, check the absorbance reading in 'service mode' and the absorbance values for service test kit vials. Also, check the optical aperture in front of the LED is still in place. If necessary, replace the optical aperture, optical filter, LED, or detector.

  If your Hach Measuring Instruments display error E-15, it means the absorbance was read > 3.5 Abs. Check for any light blockage in the cell holder and clean the cell holder. If needed, dilute the sample. You can also check the absorbance reading in 'service mode' and the absorbance values for service test kit vials. Consider replacing the detector, LED, or optical filter.

  Amber HansenAug 30, 2025
  If your Hach Measuring Instruments display error E-21, it indicates an unstable signal on the light detector. Make sure that the instrument cap is fully installed on the cell holder. Check the absorbance reading in 'service mode'. Perform a test measurement with any vial. If the issue persists, consider replacing the detector or LED.

What to do if Hach LPV445.99.02110 show error E-04?
- D
  Danielle SmithAug 31, 2025
  If Hach Measuring Instruments show error E-04, and the reading is less than the instrument range, make sure that the instrument cap is fully installed over the cell holder and measure a blank. Also, check user calibration settings. You might want to check the absorbance reading in 'service mode' and check absorbance values for service test kit vials.
