摘要

A problem determination device for a fluid device includes an object sensor for detecting an undesirable object in the fluid device and a determining section. The object sensor includes a detecting portion provided in the fluid device. The determining section determines that the fluid device has a problem when the object sensor detects an undesirable object.
