Why does the GFCI keep tripping with no load connected?

The GFCI may be tripping with no load connected due to a ground fault or a faulty GFCI outlet. A ground fault can occur if there is a leakage of electrical current to the ground, causing the GFCI to trip as a safety measure. It is recommended to have a qualified electrician inspect and troubleshoot the issue to ensure proper functioning of the GFCI outlet.
