The bunn coffee pot just pours out water when we turn the switch on. The digital display reads AN000000 Asset Number. The buttons on the front are non-responsive

Alfaroo is absolutly right on, The thermostat is either set to high or is malfuntioning The water in the tank is boiling and as it expands it has no place to go but right throw the sprayhead tube and into the brew basket.

open the cover on the brewer- depending on your model, it could be the front or the back cover. look for a brew timer dial. turn this up slowly, running a brew each time to see if you now have a full pot

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.

Your spray head has 5 to 6 little holes depending on the model and year, and it looks like you have scale, calcium or lime blocking them.
Since your model is a VPR pour model, you will have less trouble cleaning it with white vinegar than the permanent water connection type. I use a gallon of vinegar and filters for this.
2 Clean, Rinsed Empty coffee cans
1 Gallon of White vinegar
5 coffee filters
1 Toothbrush, preferrably angled head
Start with your Bunn turned off and place an empty full size coffee can under the pour spout. Now place a filter in the brew basket to catch any fine particles you don't want poured back in the resevoir and heater. You will need to change this filter a few times as the trash starts coming out of your spout.
With the coffee can, brew basket, and a fresh empty filter in place you want to start pouring the vinegar in the tank while catching the water with the coffee can. As it fills with water you will need to dump the can down the drain until the full gallon of vinegar has been poured in the Bunn. Allow the excess water to finish flowing out into the coffee can making sure to leave half the water in the can to pour back into the coffee maker.
By now your tank should be filled with mostly white vinegar, and your coffee can should be at least half full of vinegar as well.
Now you can turn on the lower pot warmer to keep the solution hot and plug your Bunn into the outlet.
Allow 8 to 10 minutes for the heater to heat up and pour the half full coffee can of vinegar into the fill area. Allow the cycle to complete and replace the filter as needed, or if flow begins to slow down.
If your heads are clogged, use the toothbrush to clear the holes as the vinegar is flowing until you see all holes flowing vinegar.
Chunks of trash will dislodge in your heater tank and flow to your spray head, so keep that toothbrush ready.
Do this at least 5 times, then allow the Coffee maker to sit 30 minutes with the heater on to finish dissolving the lime and calcium deposits in the tank.
After 30 minutes start flushing the system with clean water to rinse out all of the vinegar, or until you can no longer smell vinegar in the coffee can.
