Troubleshooting Guide for Water Flow Sensor Issues in Laser Engraving Machines

Have you ever been in the middle of an intricate engraving project and suddenly faced an unexpected halt due to a "Water Error" code on your laser engraving machine? This frustrating scenario is all too common and often stems from issues with the water flow sensor. In this article, we will explore the causes of these water flow sensor problems and provide effective solutions to get your machine back up and running smoothly.

Issue 1: Water leakage from the laser engraving machine

Solution: Locate the source of the leak. Seal it by reinstalling washers or using waterproof tape (e.g., plumber's tape) to secure the leaking hose.

Issue 2: Control Panel Displays "Water Error" Code

Step 1 . Check System Configuration:

These error codes relate to the water cooling system. Verify the setup and flow direction of the water cooling system. Inspect pipes and connections for leaks. Make sure the water outlet of the water pump/cooler is connected to the water inlet at the rear of the machine.

Step 2 . Inspect Water Flow:

Check the water cooling system for adequate water flow. Disconnect the water pump/cooler outlet and check for proper water flow. Check the water hose for kinks. Correct any water flow problems or replace the water pump/cooler if necessary.

Step 3 . Sensor Installation:

Confirm the four bolts securing the flow sensors for water are facing upwards. Adjust the installation angle if needed.

Step 4 . Sensor Testing:

Short-circuit the water flow sensor interface on the mainboard. If the error code disappears, the sensor may need replacement. If the water/cooler error persists, try the method for issue 3 following and contact Monport's support.

Issue 3: Persistence of Water/Cooler Error Despite Previous Steps

If you complete all four steps above and the water/cooler error code persists, the water flow sensor will need to be replaced. Please contact Monport for a replacement. In the meantime, you can bypass the water flow sensor using the laser software settings.

Bypassing Water Flow Sensor in Software

For LIGHTBURN:

1. Open LightBurn, click "Edit", "Machine Settings", double-click "Vendor Settings".
2. Scroll down to "Enable Water Protection" under "Laser 1" and switch this setting to FALSE.
3. Click "Save" to save changes. Test the laser to ensure it operates correctly.

For RDWORKS:

1. Open RDWorks, click "File", "Vendor Settings", enter password RD8888.
2. Navigate to the laser tab, find the waterproof protection option, and uncheck the corresponding box.
3. Click "Save" to save changes. Test the laser to ensure it operates correctly.

• Note:
  • After disabling the flow sensors for water, if the water/cooler error code stops. It means that the water flow sensor needs to be replaced.
  • If the water/cooler error persists after disabling the water flow sensor in your laser software.Your laser software may not be able to change the settings. Check your water settings again in LightBurn or RDWorks. If the error still displays, contact us for more information.

Conclusion
