Wood dust will easily fall into the cycle of water during process of engraving. With time passing, much more dust or debris fall into the water circle and leads to water flow weak or blockage. We must eliminate the debris inside the water pipes timely when this happen. Otherwise, it will cause worse result that the bearing inside spindle motor is damage. To prevent the water hose blockage, we should replace the water timely and keep it clean all the time. And it will be better if we cover a filter on water pump outlet. In this way, it can prevent debris running into water hose of spindle to protect the spindle from being blocked. 
For ordering new spindle, please click water cooling electric spindle

But if the spindle won’t pass water already, how to solve it? 

1) We can use blow pipe of air compressor to blow the water hose of the water cooled cnc spindle, please blow the inlet hose several times first, if not work, then blow the outlet hose. 

2) It is not easy to find the water hose got blocked because they are inserted in the water. So you’d better to check the temperature of spindle regularly during the process of spindle working, if you find the spindle is hot, please check the water circle at once to avoid spindle damage.
