Issue description

The processing is paused suddenly and cannot continue to process. The software displays a pop-up window.

The error code is COOL_WATER_MACHINE.ELEMENT_ABNORMAL.WATER_FLOW_LOW.

Possible causes

1. The firmware and software are not the latest version.
2. The proportion of the antifreeze is incorrect.
3. The water pipe is clogged.
4. The water-cooling system malfunctions.

Troubleshooting procedures

1. Check the firmware and software

Update the firmware and software to the latest version. And then restart the device.

2. Check the proportion of the antifreeze

(1) Check whether the proportion and volume of the antifreeze meet the actual requirements (as in the table below).

When its concentration is too high, the water flow speed will decrease. Especially when you pour the whole antifreeze into the tank, the "water flow too low" error code may occur.

Drain the antifreeze according to the link and then refill it.

(2) If the water flow is too slow, follow step 3 in the tutorial to drain the antifreeze and refill the tank with the correct concentration of antifreeze.

3. Check the water flow

1. Disconnect the power supply.
2. Follow the video to remove the upper plate and the laser tube cover.
3. Connect the power supply and turn on the device. Pinch the water pipe (as shown) and observe whether the water is flowing (When water is flowing, the pipe is relatively hard due to the pressure; when the water is not flowing, the pipe is relatively soft).
4. • If the water flows normally, check for other issues.
   • If the water does not flow or flows intermittently, go to step 4 to check the water pipe.

4. Check for bending of the water tube

(1) Disconnect the power supply, then remove the rear cover by following the video tutorial on replacing and removing the outer casing.

(2) Check whether the water pipes (as shown) are kinked or bent severely, which may obstruct the water flow.

• If not, please check for other issues.
• If so, adjust the water tube by gently straightening it or pulling it slightly to ensure it is not kinked, then install the housing and restart the machine.

5. Check the water-cooling system

If the water pipes are not kinked and the antifreeze mixture is correct, but the water flow is still too low, it means the water pump inside the water-cooling system may have failed.

See the video to replace water-cooling system.
