turn off place a rag underneath and undo large screw water will drip out replace screw and try.
you can also try pump on faster speed.

Have you got 4 pipes off the boiler? If so it is a gravity HW system and the pump has probably stuck after the summer.
Remove the silver screw as above and insert a flat bladed screwdriver, locate it on the spindle and try to turn. This should free it.
If not try tapping the pump with a hammer. If none of this works, then sounds like time for a new pump.

don't worry about the water
you said the pump was making a slight hum.

Are you certain the pump is humming and not coming from anywhere else?
If I was there I would want to test for 240VAC at the pump before deciding a new one was necessary.
If, and a big ONLY IF, you feel competent to test for this then do so with a multimeter. Remember you are testing LIVE electrics. other than that call in a heating engineer.
I have a set price of £141 for a simple pump replacement. This will vary across the country and between different engineers.

You could do some simple checks to see if you can tell if your timer/programmer and/or room thermostat appear to be operating.
Edit;
Also check that your pump hasn't got a seperate switch/fuse near it. A lot of systems used to have this in the past.
Fuse could have blown, or switch got turned off accidentally.
