A ground-fault circuit interrupter (GFCI) that repeatedly trips may be detecting moisture, a faulty appliance, downstream leakage, or a failed device. Do not bypass it or force it to stay reset.
Unplug protected loads
Unplug devices from receptacles protected by that GFCI and try a single reset only when everything is dry and visibly undamaged.
If it holds with no loads, add them one at a time
A specific appliance that trips protection may have electrical leakage and should stay out of service until inspected.
Moisture changes the priority
In outdoor, bath, and kitchen locations, moisture in devices or boxes can trip protection. Do not reset while wet or disassemble energized receptacles.
A GFCI that will not reset needs diagnosis
There may be a downstream fault, loss of supply, or a failed device. Internal wiring diagnosis should be done with verified de-energization and appropriate electrical expertise.
