Running a bypass is a fast way to test the flow switch but is not a solution for a faulty sensor.

How to bypass a flow switch? A flow switch for a pool heater monitors the passage of water through the pipe to the heater.

This action bypasses the flow switch and completes the electrical circuit back to the main control panel.
