----------------------------------------------------
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.
- Open the water pump cover with a Phillips screwdriver and check if the water is 80% full.
- Check if there is any leakage on the pump
Determine your result and the next action to take:
- Yes, it is 80% full (No leakage) >> Go to Step 2 - Check if the water is clean.
- No, it is NOT 80% full (No leakage) >> Go to Step 1.1 - Fill up the water.
- The water pump leaks >> Hardware issue: water pump is broken. >>
Please record a video and Go to Step 9 - Report to the local reseller or FLUX Support.
------------------------------------------------------------------------------------------------
Step 1.1 - Fill up the water:
- Please refer to the video in the link below to add more water to the pump.
[5-5 Water Cooler Maintenance] - 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:
- Yes, the problem is solved.
- No, the problem is not solved >> Go to Step 2 - Check if the water is clean.
------------------------------------------------------------------------------------------------
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:
- Yes, it is clean >> Go to Step 3 - Test the flow speed.
- 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.
[5-5 Water Cooler Maintenance] - 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:
- Yes, the problem is solved.
- No, the problem is not solved >> Go to Step 3 - Test the flow speed.
------------------------------------------------------------------------------------------------
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:
- 1.0L/min or above = Good value:
- The #900 error still pops up during tasks >> Go to Step 8 - Reflash SD card
- The #900 error does not pop up during tasks >> Problem solved.
- 0L/min ~ 0.99L/min = Bad value:
- If this is your first test >> Go to Step 4 - Check the water hoses
- If you already checked the water hoses in Step 4 >> Go to Step 5 - Check if the water pump can be activated.
- If you already tried activating the water pump in Step 6 >> Go to Step 7 - Replug the cable of the flow sensor
------------------------------------------------------------------------------------------------
Step 4 - Check the water hoses:
If you have a bad value that is bigger than 0L/min and smaller than 1.0L/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 - Water pump:
- Location #2 - Radiator & Cooling fans:
(The side cover has to be opened first. Use a Phillips screwdriver to unscrew this screw.) - Location #3 - Laser tube:
(The back cover has to be opened first. Use a Phillips screwdriver to unscrew this screw.)
Determine your result and the next action to take:
- The hoses are in good positions >> Step 5 - Check if the water pump can be activated
- The hoses were adjusted and realigned >> Test the flow speed again (Go to Step 3)
- The hoses are bent but not able to be adjusted.
>> Hardware issue: Water hoses are too short, long, or leaking. >>
Take photos of the problematic hoses and go to Step 9 - Report to the local reseller or FLUX Support.
------------------------------------------------------------------------------------------------
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:
- The blue LED inside the tank will be ON.
- 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:
- Yes, the water pump is activated, but:
- The flow speed test is only 0L/min.
>> Go to Step 7 - Replug the cable of the flow sensor - The flow speed test is bigger than 0L/min but smaller than 1.0L/min.
>> Hardware issue: the water pump is too weak and needs to be replaced. >>
Record a video of the flow speed test with a bad result and state that the hoses have been checked then Go to Step 9 - Report to the local reseller or FLUX Support.
- The flow speed test is only 0L/min.
- No, the water pump is not activated. (The LED is OFF or the water is not being pumped).
>> Go to Step 6 - Try to physically activate the water pump
------------------------------------------------------------------------------------------------
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:
- Enable the pump on the Maintain page first and pinch both hoses at the pump's inlet and outlet to apply pressure with your fingers.
(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 on the pump with a hand.
(It could be the pump's turbine being stuck and causing the pump not to pump water.)
If the blue LED is OFF:
- Replug the water pump's cable on the plotter board at the back 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 plotter board 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.
Determine your result and the next action to take:
- After replugging, the flow speed test is 1.0L/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 1.0L/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.
- The error doesn't pop up during tasks. >> Problem solved.
- After reflashing, the flow speed test is still 0L/min >>
