Question about Bunn Coffee Makers & Espresso Machines
I agree with Chrissie. If you have hard water then the heating element has a thick layer of calcium or lime coating it.
If vinegar doesn't do the trick, then try running CLR through it. That's a little more aggressive. If that doesn't do it, then use muriatic acid. That will definitely eat away any calcium or lime from the burner.
Make sure you do 3 full rinses by running clear water through it the same way you would be brewing coffee.
If none of that works, buy a new coffee maker.

Clean a Bunn coffee maker once every three months if you have hard water. ... Unplug the Bunn coffee maker from its power source. Verify the brew funnel is in place in the machine, and set the decanter in the unit as if you were going to make coffee. Add 1 quart of white distilled vinegar to the top of the brewer.

Use the de-liming spring to clean the copper tube behind the spray head. Pour several pots of clear white vinegar through the unit to further remove lime and scale from the interior of your coffee maker. My Bunn is 24 years old, and the only replacement parts I've ever required are new carafes and the 4041 silicone washer repair kit.

SOURCE: Bunn coffee maker leaks water
There are 3 seals in your unit that could cause your problem. there is a silicon seal right under the pour-in tray, and two on the top of the tank. one of those is for the thermostat, the other is for the sprayhead tube. any of these could leak, causing water to come out the bottom of the brewer. One other thing that can cause this is a scale buildup between the pour-in tray and the tank.

Hello. I would like to suggest that you pour in water, with a container under the funnel, until water does come out, it sounds like the water has just evaporated too far, and it requires more than a pot to bring it to the top. In the future, if you do not use it for a day or more, you need to unplug it, or just pour a pot of water in to keep it at level, as this unit heats all the time it is plugged in, and can actually evaporate all the water away, blow the element, damage the thermostat, or worse permanently damage the unit.
here you can find the user manual:
Hope that helps, and thank you.

The first pot of water you put in the coffee maker just fills the water tank which is then heated up , once it gets to temperature you then pour second pot of water this pushes the hot water out of the tank through the coffee grounds into the waiting pot. This way you can make coffee faster than a regular coffee maker.
