Question about Bunn GRX-B

No power getting to Bunn coffee maker

Turned off and unplugged my Bunn coffee machine to vacation for a week. I am back now, and the unit no longer works. I plugged it in, and power getting to the maker at all. I checked the fuses at the outlet and at the circuit breaker, and they work fine--just not the coffee maker. Any suggestions?

Okay, When going away most people empty the tank completely. When returning you must start it as if brand new out of the box. Follow the MFR's instructions for an initial fill and heating.
Some don't empty but just unplug just as you did. Places like Arizona with very low humidity can dry out or lower the tank water where the heating element is not in water. This element will overheat and trip out the thermal fuse.
**Another scenario is the empty unit was plugged in and heating while someone was going to get the water. Over heat then blows fuse.
** The "Vacation" switch is very visible so you probably have tried it already and you have already checked the outlet and breakers. Still looks like a thermal fuse problem.
** Switches do go bad as they are turned on and off daily. Possible yours was bad before but never noticed as it was never turned off till on vacation.
** There are other possible scenarios but all point to a thermal fuse, thermal limit, blown fuse, switch, Heater element, or cut wire (Mice). All are electrical problems and require a MFR tech. Contact your vendor or MFR for service.

SOURCE: weak coffee

It sounds like you may have lost the sprayhead. It is under the brew basket (above the place where you put the basket with the filter and the coffee). Sometimes they get loose and you don't realize it and it can fall in the grounds and get tossed out after brewing.

SOURCE: Bunn coffee maker keeps tripping circuit breaker

This is usually an electrical problem with your brewer. If you will get the model and date code located on the bottom of the brewer and contact Customer Service, you machine can either be replaced at no cost if under 3 years old or if over 3 years old, at a reduced cost.

Won't get hot

Don't know the model but here are things to check prior to calling your vendor for service:
* Plugged in? No lights? Check if GFRI outlet is tripped out.
* Is it turned on and ready light lit? Some (CWTF's etc.) have a green or read ready lamp that lights up when the brewer is hot and ready to brew.
* No Ready light after 15-20 mins of being plugged in? Cheuck the back of unit for a toggle switch (or rocker switch). Check if it's on. Some units may say "Vacation". It should be on normal or brew.
* Brewing works but not hot. Was the ready light on when you started the brew? You have to wait till it's lit. Still not hot? Then call for service. The heater, High limit, Thermal fuse,Thermostat needs to be checked.
* If this is a new unit then be sure to turn on the thermostat as it comes from the MFR in the off position.
* Final, Call your vendor to be safe.

I unplugged my bunn for vacation and now it won't come back on I forgot about the vacation switch It has always worked fine before.

If it's plugged into a GFCI outlet, press the RESET button. Do not press the "test" button.

If still no joy, plug something else into that outlet and see if it works. If it doesn't, check that the breaker on your main panel for that circuit isn't tripped. If it is, push it all the way to the off position, then back to the on position. You should hear it click like a light switch.

Bunn GRX-B won't heat and yes it is plugged in and vacation switch is on

You said "...turned vacation switch back on". In fact, it should be turned off for normal use.

If that's not the problem, and it's plugged into a GFCI outlet, press the RESET button (do not press the "test" button).

If still no joy, plug something else into that outlet to see if it works. If it doesn't, check the circuit breaker for that outllet.

Do you have to unplug coffee maker when not in use?

You dont have to unplug unit but you can if you like. Most people leave them plugged in. This keeps water hot and on the ready when you need coffee. When the unit is unplugged there is a waiting time before the water comes to temp. If your unit will not be used for weeks at a time, I would unplugged it, but if used regularly
I would leave it plugged in.

Our BUNN vpr is plugged in 24/7 and stays warm all the time. This seems like a big waste of electricity to me, but I have been told that when they tried to unplug the last one between uses, they had to buy...

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 (CWTF's have a toggle switch behind the machine). Brewer will pre-heat the water (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.
* FYI Coffee grounds are usually in pre-measured packets for office use. A simple guide is one tablespoon per cup. (level or heaping spoon is up to you)
* Final; Getting back to unplugging when not in use. Yes there is a heater in the machine that keeps the tank warm. You can save power by turning off the warmer plates when not in use. Some units have up to 6 plates. The warmer "Blanket" is designed to keep the tank warm enough to brew and not waste heat or electricity. Yes unplug the unit at night if there is no night crew drinking coffee (or tea) But 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 for down loading. (*FREE*)

I haveBX-B . I had the pot set up for me to push the on button for Monday Morning, but the water ran throug and it was not on.So now I have cold coffee in the Decanter.

The Bunn coffee maker does not operate as most coffee makes do. You cannot leave the Bunn in the off position and then just flip the switch to on and pour the water in. You will always get cold coffee if you do this. It takes time for it to heat the water. The On/Off switch should be left in the On position all the time. This keeps the water hot in the tank, thus providing hot water when you need to make coffee. You then just pour the cold water in the top, shut the lid, and have a pot of coffee in 3 minutes. The On/Off switch is a vacation switch, and you use it only when you are not going to use the coffee maker for a couple of days. Older Bunn coffee makers did not even have an On/Off button. You simply unplugged them when going on vacation. So turn the switch to the On position and leave it there. The unit will then work as designed. Forget how other coffee makers work, this is a Bunn and it is the fastest coffee maker you can buy and must be left on all the time. that way the water stays hot and the unit will keep it that way.

Just bought a Bunn coffee maker at a garage sale great condition how do you make the coffee I have poured water in turned the side switch on and the warmer switch yet nothing?????

The machine requires an initial set up to be completed before using it. Fill the decanter with cold water and close the lid. It will take 3 minutes to partially fill the water tank in the back. Then fill the decanter again with cold water and pour in and close the lid. Then plug in the machine and turn the vacation switch on the side of the machine on. After 15 minutes, you will be ready to brew coffee. Then you will get your filter basket ready with the filter and grounds. Pour in from 4-10 cups of water and place the decanter on the base. Close the lid and the coffee will begin to brew. If you will call customer service with the model and date code, a use and care manual can be sent out to you at no cost.
