My ejector is not working. All it does is hum and it does not eject the water. What does this mean?

Is it a grinder or just a sump pump? May have something stuck in it. I would remove the pump, look in the bottom side to see if you can see anything that may be locking it up. See if you can turn blades by hand. Let me know what you find.

You could have a obstruction in the impeller cage but I doubt it. Sounds more like a open motor winding to me. Pull the unit and check, Good luck, Tom
