Month Old Bunn smells hot
Bunn machine smells hot
* Check for unusual sounds from brewer (other than sizzling from warmer plates). There should be a gradual boiling sound accompanied by some steaming at the top of brewer. This will turn off and ready light indicating the brewer is ready to brew.
* You may sometimes hear a slight boiling sound from time to time (about 15-30 mins apart). Notify your vendor as the warmer blanket may be out. (your brewer will still work but call them anyway.)
* Check your manual for setting up procedures and checks. It's available on line: http://www.bunn.com/product-manuals
* Constant boiling (more than 15 mins) with lots of steaming is a sign of an electrical problem. Unplug machine and call vendor for service.
* Final; Unplug unit and check for 'stuff' in pour over tray. I've found Chocolate, Cream, Milk, powder, sugar, honey, and a dead rat in the tray. Crew will repour old coffee or beverages into brewer to 're-heat' them. Notify vendor for cleaning or replacement (it happens all the time.)

Our Bunn VRP SERIES MAKES NOISE WHEN WATER IN THE TANK SITS AWILE
There are two heaters in a VRP unit (Pour over style) The brewer has a tank that your last office person poured in a full pot of water. The main heater senses the colder water and begins to reheat the water to near boiling. The new water pushes out the same amount of water into the brewing basket (funnel with coffee). Once the new water has come up to temperature then the main heater turns off. There is a warming blanket around the inside tank. This keeps the water hot and ready to brew. It uses less power than the main heater. If this blanket fails then the water will cool down to a point where the main heater heats everything back up. You may not notice this as the only indication is luke warm coffee on a freshly made pot or a 'boiling' noise every 15 - 25 mins. This VRP probably needs servicing (check Thermal blanket and Thermal fuse)
My Bunn nhbx-b leaks water when brewing coffee
you could remove the cover and look for the connection that isn't connected properly - - be careful not to touch electrical connections/bare wires when cover is off - or take it to a technician - or contact Bunn directly for suggestions.
