Draining dehumidifier to AC condensate pump

So, I have a dehumidifier with a garden hose attachment. I have a condensate pump for my HVAC, and it has an open port. So, I attached the garden hose to my dehumidifier, elevated it, and ran the hose (about 3' length) to the open port of the condensate pump.
Came back a few days later and found water on the floor. Seems like the water from the humidifier overflowed out of the port instead of being pumped out by the condensate pump. Hose was still in the port. When I touched the hose the water shifted enough to trigger the float switch and the condensate pump turned on. Confirmed from the outside that it was indeed pumping out.
So, what happened? Is my condensate pump just on it's last legs, or is there something I should have done differently?

If you jiggled the pump and it started...... It sounds like the float is getting caught.
It needs to be taken apart and cleaned.
If it's severely corroded.... it may be time for replacement.

Make sure your dehumidifier's hose wasn't hitting the condensate's float switch when you shoved it in. Most condensate pumps have small sumps and there isn't a lot of extra room inside.

I'm starting to think that's what happened. Since I removed the hose, the pump sump has been draining completely. Maybe I need to put a clamp or something on the hose so it doesn't go in too far.
