Grx Bunn coffee brewer will not brew. I've followed all directions carefully. I've waited almost 30 min for it to heat up I've added more water and still nothing. Now I have been waiting for about an hour and still nothing is coming out.

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*)

* You can test the VPR by following the Pre-fill instructions I've listed earlier. If the brewer heats up and does not continuously boil (shorted condition) then try a brew. If it works then your okay. Otherwise the unit will need service for a blown high limit or bad heater element.
* Call your coffee vendor anyway. Many coffee vendors will service your brewer of even replace it as long as you buy coffee from them. Ask around.

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

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.

This is really a home style VPR brewer (but looks nicer)
if you listen to their video (link below) they mention it has a pre-heated tank of water already in the brewer. This means the brewer needs to be pre-filled with a full pot of water and pre-heated prior to using the brewer. Unplugging this unit won't be a problem UNLESS it was emptied of tank water and not refilled when powered up.
* The unit will try and heat up the tank of water but if empty then just air which overheats the unit then blows the thermal fuse. Call for service.
* The warmer is still working but it's not hot enough to brew frequently as the warmer may take up to an hour to get the tank hot enough to brew or it may not get hot at all if it's own thermal fuse blew too.
* Water leaking while the brewer just sits there? Leak in the tank. Call for service.
* water leaks only while pouring? Then your pouring to fast. Wait for the water to drop before pouring in more. If it still leaks even while pouring slowly then there is a leak in the fill tray. Call for service.
* Final; call for service to be safe.

You should call your vendor for service. Especially if it's on loan from them.

* FYI Coffee grounds are usually in pre-messured packets for office use. A simple guide is one tablespoon per cup. (level or heaping spoon is up to you)
* Since your brewer was bubbling at one point. I'm guessing it had water in the pre-heater at one time. But if it's not in use and left plugged in all that time then the water has probably boiled off. Hopefully someone unplugged the brewer prior to the unit blowing the thermal fuse.

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.

While this brewer does have a reservoir that keeps a couple of pots worth of water hot for brewing you can get a cooler second pot if you brew directly after. You should hear the brewer heating up after brewing. Try waiting until it is back to temperature before re-brewing. If that heating takes more than a few (3-4) minutes then you probably have a problem with the heating element and the water is only being heated by the "keep warm" heater.

If you will call 800-352-2866 we will be happy to further assist you in getting your brewer to work properly.

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!
