If The Pump Does Not Start, The Water Cannot Be Purified:

1) Check whether the raw water pressure fails, and the low-voltage switch is powered off.

2), check whether the high-voltage switch fails and cannot jump back.

3) Check whether the fuse of the transformer is burned out. If it is burned out, please check whether the granular activated carbon or sintered activated carbon filter element is blocked and the pump is overloaded.
