Bunn GRX-B 10 cup coffee brewer kicks breaker when we turn it on

VPS/VPR are pour over brewers. Like the 12 cup brewers you find at home, they need to be filled with 12 cups of water (a full pot), heated and then peculated over the coffee grounds and collected in a decanter.
BUT there is one main difference! The VPR and similar COMMERCIAL coffee machines are quick brewers. They usually have a pre-heated pot of water stored inside the machine.
* VPR's and similar machines REQUIRE a pre-fill and heating period prior to brewing. This means it's sitting on a level table and filled with water until water sprays from the brew head. At this point the unit is plugged in and the heater is turned on (there may be some water discharge from brew head as the water expands). Ready light will come on in about 15 mins.
* To Brew; Place coffee grounds in filter, place in funnel and brew head, clean empty decanter under funnel, slowly pour one full decanter of water (cold or hot) into brew tray. Do not overflow tray. Allow water level to sink before adding more water. Only fill with one pot as an equal amount will come out the brew head and funnel.
* Make sure the decanters are all the same size. do not mix a 12 cup pot with a 10 cup pot. One will over fill and the other will under fill. Make sure they match (in cup volume) FYI; Thermo Air pump pots are usually bigger than one pot. Typical filling only to 3/4th of the container. (I think most are in 2.5 to 3 liter sizes)
* If your not getting a full pot then the brewer was partially empty. The second brew (if done within the next hour) should come out full.
* If your still not getting a full pot then the water is leaking or is boiling off. Does it always steam from the top? Thermostat is shorted. Unplug the brewer and call vendor for service.
* Final; If your unplugging when not in use. Then follow the Pre-heat instructions mentioned above prior to plugging the brewer back in. If the tank has been emptied at night or dried up after an idle week. Then there is a chance you may over heat and blow the thermal fuse. Or at best have a half pot short brew as the water dried up.
* Note leaving the brewer plugged in without brewing daily is not a good idea. The water evaporates and eventually drys out the pot. Takes about 1-2 weeks but it does blow the fuse(s) and the unit will need service.
* Final; Follow the Bunn set up and care instructions (manuals from Bunn.com for down loading. *FREE*)

if the coffee pot does not work right, take it back and get another one...

This is a common question for the BTX-B.
It's a commercial brewer that needs to be pre-filled prior to turning on.. It also needs to be filled again with a full carafe for it to brew properly. I have a link below that will explain how to set up and use this brewer.

I would check your electrical supply. Plug in a hair dryer where the coffeemaker was plugged in and see if it works. If it doesn't there is probably nothing wrong with the coffeemaker.

VPS/VPR (VP17-3 are the same except it has 3 lower warmers) are pour over brewers. Like the 12 cup brewers you find at home, they need to be filled with 12 cups of water (a full pot), heated and then peculated over the coffee grounds and collected in a decanter.

Maybe limed up.Try running a deliming spring in the brew tube.Bunn p.n. 1111.0000.

This machine is still under warranty. If you will give customer service a call, we can replace it for you at not cost. The # to call is 800-352-2866.

It sounds like the tank isn't full. It takes 2 full decanters of water to fill the tank in the bank. After pouring in 10 cups of water, close the lid and wait 3 min. Then open up the lid and pour in another 10 cups of water and close the lid. Then turn the vacation switch on and wait 15 min. Now you are ready to brew coffee. Place your grounds and filter in the funnel basket and pour in 4-10 cups of cold water and place decanter on warmer plate. Close the lid and in 3 min you will have a pot of coffee. If this doesn't happen, please call 800-352-2866 and we will be happy to assist you.

there's probably a 'silicon rubber' hose that feeds hot water to the 'grounds basket'- it may be loose, or damaged. is it leaking water, or coffee?? we have a bunn 8-cup, which has a pre-heated water tank that brews a pot in about 3 min. energy waster, but when you need coffee, you need coffee!!! is your filter holder properly centered? is the carafe lid hole clean and un-obstructed?
if it's leaking water, and not too costly to replace- you may consider replacing it with a new one!
good luck!
