If a false alarm and the water level is not really high, a plumber would be your normal solution. You can also try fiddling with the float - may be stuck on some debris or corrosion.

If actually high water in the sump and your pump is not working check circuit breaker, and most units also have a quite small push-to-reset circuit breaker on the pump itself - usually on top of motor near outer shell. You can check if you have power to the pump by unplugging it and plugging in some device that you know works.

If no power to outlet and resetting circuit breaker does not solve it, then you need an electrician. And a friend/neighbor with a portable generator to get it running again, if water level is rising fast.

If pump has failed, you can pull it out of sump and check the bottom (with it unplugged) to see if impeller (rotor) is jammed with debris. Do NOT get your fingers in there - some can rotate a bit if jammed and nip a finger, plus usually pretty sharp. Use tools to remove any debris blocking it. Should spin fairly freely if not blocked. If still does not work, Plumber is normal contractor for replacement. Or if somewhat home handy DIY by buying similar one at store and necessary makeup plastic pipe fittings and joint cleaner and glue and maybe a short nipple piece to hook the new one up.

If flooding and can't get repaired quickly, then hand bail or hook up another type pump, depending on how fast water is coming in. If not enough room to bail and can't get pump, unplug, disconnect piping (usually a threaded connection near the pump or cut pipe midway in a straight section if you have to) and disconnect the alarm, and pull the pump out of the pit so you can bail, if water is rising fast enough to need that.
