When a sump pump runs continuously without shutting off, you can stop it by identifying and resolving the underlying blockage or switch failure. First, check the float switch to ensure it is not physically stuck, wedged against the side of the sump pit basin, or tangled in a cord. If the float moves freely but the motor continues running, unplug the pump's power cord from the electrical outlet to prevent motor burnout. Verification: Manually lower the float switch or unplug the unit to confirm the motor successfully stops running.
