Description:

The error pops up when a low flow speed is detected in the system and the task will be paused.
The speed being slow will cause the laser tube to run at a higher temperature and it will result in reducing the lifespan of the tube.

Please follow the instructions below to troubleshoot the issue.
----------------------------------------------------

Step 0 - Use the checklist while going through the steps:

This checklist will be used to record all your taken actions in this article.
After completing the checklist, please print it to save as PDF and send it to your reseller or FLUX Support if necessary. This will be useful information for us to troubleshoot and narrow down the issue.
Please refer to the link: 5-2-1 #900 Cooler off (beamo)

----------------------------------------------------

Step 1 - Check if the water is 80% full:

If your machine doesn't have enough water, this may affect the flow speed to be lower. 

  • Remove the back cover with a Torx screwdriver (T8)


  • You will find the water pump underneath the flow sensor.

  • Check if the water is 80% full.

  • Check if there is any leakage on the pumppump_leaks.gif

 

Determine your result and the next action to take:

----------------------------------------------------

 

Step 1.1 - Fill up the water:

  • Please refer to the video in the link below to add more water to the pump.
    [4-4-2 Water changing and adding]

  • After filling up the water, please check if the problem is solved by running a random task.

 

Determine your result and the next action to take:

----------------------------------------------------

 

Step 2 - Check if the water is clean:

Water being dirty will affect the flow of the water. Make sure to have clean water in the system.

 

Dirty example:

Clean example:

Determine your result and the next action to take:

  1. Yes, it is clean >> Go to Step 3 - Test the flow speed.
  2. No, it is not clean >> Go to Step 2.1 - Change water.

----------------------------------------------------

 

Step 2.1 - Change water:

  • Please refer to the video in the link below to change the water.
    [4-4-2 Water changing and adding]

  • After changing the water, please check if the problem is solved by running a random task.

 

Determine your result and the next action to take:

 

----------------------------------------------------

 

Step 3 - Test the flow speed:

Please perform a flow speed test and see if the value is normal.
(Machine Panel > Machine > Hardware Settings > Flow Speed Test )

Determine your result and the action to take:

----------------------------------------------------

 

Step 4 - Check the water hoses:

If you have a bad value that is bigger than 0L/min and smaller than 1.5L/min, this indicates your whole system works okay, but the flow speed is too low and this might be caused by water hoses being bent or kinked.

  • Bent hose: (Bad example)

There are three locations to check for water hoses.
(If your hoses are bent or kinked, please try to adjust their positions.)

  • Location #1 - High-pressure side (Close to panel):

  • Location #2 - Water Pump Inlet/Outlet:

  • Location #3 - Laser tube:

Determine your result and the next action to take:

----------------------------------------------------

 

Step 5 - Check if the water pump can be activated.

Please refer to the video below for how to perform the test.
(Machine panel > Maintain > Pump > Check the pump at the back)

  • How to check:


If a water pump is activated successfully, it will have two behaviors:

  1. The blue LED inside the tank will be ON.

  2. The water inside the tank will be pumped.
    (You should see the water flowing or bubbles popping up slightly.)

Determine your result and the next action to take:

----------------------------------------------------

 

Step 6 - Try to physically activate the water pump:

Please take the following actions to try to activate the water pump.

If the blue LED is ON but the pump is not pumping:

  • Remove the cap of the pump and enable the pump on the Maintain page.
    Pull up the hose to apply pressure as in the video below.
    (It could be the stuck air in the system that the pump is not able to push.)



  • Enable the pump on the Maintain page first and try to knock inside the tank with a pen.
    (It could be the pump's turbine being stuck and causing the pump not to pump water.)


If the blue LED is OFF:

  • Please remove the front cover of the machine.


  • Replug the water pump's cable on the mainboard in the front to the right of the machine.
    Please refer to the diagram to find the water cable to replug.
    (It could be the cable's connection being loose causing the pump not working)

 

Determine your result and the next action to take:

  • Yes, the water pump is activated after the steps above.
    >> Test the flow speed again (Go to Step 3)

  • No, the water pump is not activated after the steps above.
    >> Hardware issue: the water pump is dead and needs to be replaced. >>
    Record a video of the problematic pump while the pump is enabled on the panel and go to Step 9 - Report to the local reseller or FLUX Support.

----------------------------------------------------

 

Step 7 - Replug the cable of the flow sensor:

A bad flow speed may be affected by improper connection of the flow sensor.

  • Replug the flow sensor's cable on the mainboard at the back of the machine.
    Please refer to the diagram to find the cable to replug.

  • Once you've replugged, please run a flow speed test and see how it goes.
    (As in Step 3)

Determine your result and the next action to take:

  • After replugging, the flow speed test is 1.5L/min or above:
    • The error doesn't pop up during tasks. >> Problem solved.
    • The error pops up during tasks >> Go to Step 8 - Reflash SD card

  • After replugging, the flow speed test is still 0L/min.
    >> Go to Step 8 - Reflash SD card

----------------------------------------------------

 

Step 8 - Reflash SD card:

Please refer to the article to reflash your SD card and then run a flow speed test.
(The purpose is to see if this is firmware issue related or hardware issue related.)

 

Determine your result and the next action to take:

  • After reflashing, the flow speed test is 1.5L/min or above:
    • The error doesn't pop up during tasks. >> Problem solved.

    • The error pops up during tasks >>
      Hardware issue: Mainboard or Flow sensor is having a problem. >>
      Please take a photo of the flow speed test and the error during a task and go to
      Step 9 - Report to the local reseller or FLUX Support.

  • After reflashing, the flow speed test is still 0L/min >>
    Hardware issue: Mainboard or Flow sensor is having a problem. >>
    Please take a photo of the flow speed test and the error during a task then go to
    Step 9 - Report to the local reseller or FLUX Support.

----------------------------------------------------

 

Step 9 - Report to the local reseller or FLUX Support:

  • Please follow the instructions in the link below to properly report an issue to your local reseller or FLUX support. [Contact Customer Service]
  • Make sure you've completed the checklist and saved it as a PDF file so you can share your taken actions. 

*The collected information such as photos or videos that show the problem of your machine in this article will be necessary to be shared with the reseller or FLUX Support.
