To get a continuously running sump pump to stop, follow a safe diagnostic sequence. Step 1: Inspect the sump pit to check if the float switch is physically wedged against the basin wall or tangled. Step 2: Manually lift and drop the float to free the internal switch contacts. Step 3: If the float is free but the motor keeps running, unplug the power cord immediately to prevent motor burnout. Verification: Confirm that the motor halts completely once unplugged or once the float switch drops to the bottom.
