Issue description

When this issue occurs, processing can't be carried out. If the machine is connected with xTool Studio or xTool Creative Space, you may see a pop-up notification like below.

Possible causes

• High antifreeze concentration
• Low antifreeze level
• Water pump malfunction
• Water flow sensor malfunction
• Water cooling controller board malfunction

Troubleshooting procedures

1. Check the antifreeze mixture ratio

Please check whether the antifreeze mixture ratio is correct. A common cause is pouring an entire bottle of antifreeze directly into the water tank.

• If the ratio is incorrect, re-mix it according to the table below and ensure the antifreeze is thoroughly mixed. Both P2 and P2S users can refer to the following tutorial on how to drain the antifreeze: Drain the Antifreeze from xTool P2
• If the ratio is correct, proceed to check for other causes.

2. Check the antifreeze level

(1) Check the liquid volume in the water tank.

(2) The proper volume should be at least up to the level shown in the following figure.

(3) If the level is insufficient, mix the antifreeze solution according to the specified ratio and add it to the tank.

3. Check the water pump

(1) Turn on the device. The water pump will keep running after startup.
(2) Touch the pump to see if it vibrates (slightly), or observe if the water in the tank is continuously rippling:

• If so, the pump is working. Proceed to check the water flow sensor.
• If not, the pump is not working. Proceed to check the pump terminals.

4. Check the water flow sensor

(1) Disconnect the water flow sensor connector.

(2) Set the multimeter to the DC voltage mode and measure the voltage between the two pins shown below:

• If the voltage is approximately 3.3 V, the terminals are normal. Replace the water flow sensor.
• If the voltage is 0 V, replace the water cooling controller board.

(3) If a multimeter is not available, try powering off the device, disconnecting and reconnecting the water flow sensor connector, and then restarting the device.

5. Check the water pump terminals

(1) Unplug the water pump connector.
(2) Set the multimeter to the DC voltage mode and measure the voltage at the water pump connector:

• If the voltage is stable at approximately 24 V, replace the water pump.
• If the voltage is significantly lower than 24 V, replace the water cooling controller board.
