Abstract：Fresenius 4008 series hemodialysis is widely used in clinical practice, all kinds of flow problems are easy to occur. But
it still lack of analysis and solution for the faults of whole flow system. First the basic working principles of the flow system of
fresenious hemodialys was introduced, then common faults of the flow system were collected. By combining the waterway map and
physical map, we found out the causes and solutions. This troubleshooting can provide reference for maintenance engineers.
