I own a bunn and my brother's business owns 2 of these. The rule of thumb as he was told by the salesman is 2 oz of coffee grinds per 48 oz of water.

SOURCE: does not brew a full pot of coffee

I had the same issue, poured in 8 and out came 6. Here's what I did to clean and fix.
1) Unplug the NHB
2) Remove accessories like the pot and basket
3) Bring NHB over to the sink
4) Snap off the entire top cover (not the swing lid) by starting at the front and lifting upward (the top cover is about 1/4" thick). The back of the top cover will pivot a bit and then pop off exposing the pour reservoir. Remove the flow stopper inside the pour reservoir by lifting it straight up.
5) Place the top cover and flow stopper aside.
6) Remove the brew diffuser (located underneath the top where the brew basket goes. Twist counterclockwise gently but forcefully enough to snap it past the lock tabs which hold it in place. You'll know that it you've done this correctly when it just falls out.
7) Still over the sink, tip the NHB in a fashion where the back side is facing upward and the brew side is facing down into the sink. You'll be holding the NHB horizontally by the top and bottom of the unit. This will allow any water in the tank to pour out the brew spout. Begin to tip the unit as if tipping upside down as this will allow any remaining water to drain out. If this does not work the brew spout hose may be clogged and you can just tip the unit entirely upside down to empty it from the fill hole in the pour reservoir.
8) Return the NHB to the upright position in the sink.
9) Using a scotch brite sponge and some baking soda, clean the inside of the pour reservoir and rinse.
10) Using the tool Bunn provided, clean out the brew spout hose which is located under the brew hat. This is the little hole where the water comes out. If you don't have the tool Bunn provided you could use something like a plastic tie-wrap. Don't use anything metal as the hose you're cleaning is made of plastic tube and could become punctured. Clean this hose for just a minute or two to ensure that there are no significant obstructions.
11) With the NHB upright in the sink, pour a slow stream of hot water from the faucet, about two cups, directly into the fill hole located in the pour reservoir.
12) Tip the unit horizontally, as in step 7, and place the tip of your finger over the pour reservoir fill hole covering it completely.
13) Shake the unit back and forth horizontally so the water in the tank splashes around and frees anything which may be built up in the tank. Some water may splash out of the brew spout hose.
14) Tip the unit as in step 7 to drain the tank water out.
15) Fill a 16 ounce glass with hot water and 2tbsp baking soda, mix and pour into the pour reservoir fill hole.
16) Repeat steps 13 and 14 once.
17) Repeat steps 11 through 14 three times.
18) Clean the pour reservoir cover, swing lid and flow stopper.
19) Put the flow stopper back in place.
20) Attach the top cover.
21) Clean the exterior of the NHB.
22) With the boil and warmer switches off, plug the NHB into the electrical outlet.
23) Turn the boil and warmer plate switches on.
24) Fill the NHB with one pot of cold water and close the swing lid. Wait one minute.
25) Fill the NHB with another pot of cold water. Place the pot on the warmer plate and close the swing lid. If water does not yet come out, fill with one more pot of water.
26) Allow water to drain from brew spout until it stops draining.
27) Empty pot.
28) Fill pot to 10 cup line and pour into the NHB. You should find that the NHB now delivers 10 cups back to the pot. Empty the pot.
29) Clean brew spout diffuser and replace back in the brew hat.
30) Clean the pot, pot lid and brew basket.
31) Wait ten minutes for the water in the tank to boil.
32) Brew your coffee as you normally would.

The only issue I experienced during this process was with the warmer plate switch. It appeared that the light in the switch blew although the warmer plate still warmed normally. Shortly after the water in the tank started boiling the warmer switch light started operating again.

SOURCE: Vanishing water

Is this problem happening by chance after you have used the maker? If so the heat from the previous use may be causing the water to steam from being so hot and thus causing the pot to be only half full. the hotter the maker the more water evaporates. You might need to let it cool down in between pots.

SOURCE: Filter basket overflows after cleaning Bunn VPR Coffee Maker

Make sure you are using BUNN brand cupcake filters, not the shorter-sided generic variety. Also, inquire with BUNN about an optional attachment for some models that will slow down the rate of water flow. Lastly, ensure that you are not over-filling the basket with grinds. There is an upper limit to how much a coffeemaker will hold, and some people try to compensate for weak coffee by adding too much.

Hello. Bunn coffeemaker VPR Series. When water is poured in coffee starts to make. Carafe gets about 1/3 full and then just drips through filter for about 5 minutes. Never makes full pot.


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*)

Bunn coffee maker leaks


VPR has a semi-sealed tank that keeps +1 pot of water heated and ready to brew. Pouring in a full pot of cold water will fill the top tray and allow a slow trickle of cold water into the top which forces hot water to over flow into the brew basket. This continues until all the cold water drains into the heater tank. So the brew is matched volume per volume. UNLESS the tank was empty or not filled prior to brewing. Follow the brewing instructions from Bunn (on line for *FREE* download at Bunn.com)
* If it leaks (from the bottom) only when you pour in water. Then your pouring it too fast and over flowing the fill tray. slowdown, watch the level in the tray. do not fill past the lid.
* If it leaks just sitting (not brewing) then there is a hole in the tank. Call for service.
* If it leaks after filling the tray half way. then the top of the tank has a leak, loose, cracked, or missing gasket. There is quite a few gaskets on the lid. Call for service.
* Final; Leaks are always bad around electrical equip. Best to unplug and call for service to be safe.

Bunn pour omatic commercial coffee maker will not brew and it leaks


VPR is a pour over "Volume Displacement" brewer. Required to completely fill the inner tank and heat prior to using brewer. BEFORE plugging in unit, water must be poured into upper tray and with brew funnel and empty pot in place. Keep pouring water into top fill tray until water drips out of brew funnel. Plug in VPR and allow it 15-20 mins to heat up. leave the pot as there may be additional water dripping. Remove power if there is any water spilling out from other places like the top pan cover or bottom of machine. With the initial heating done, take a full pot of water and slowly pour into the top filling tray. HOT steaming water should come out of the brew funnel to fill the (empty) pot. Prep is done and the machine can be used to brew a pot after 10-15mins of reheat time.
*** the machine you have needs to be checked for leaks in areas mentioned above. Water should only come out of brew funnel (if not present then the brew head or if that is missing then the brew pipe. All will need to be replaced prior to brewing.) Leaking under machine is an indication of leak(s) in pour tray,tank,tank cover, gasket, probe gasket. This machine like any used equipment should be checked out by qualified tech prior to use. Be aware that coffee vendors sometimes rent or loan brewers to customers.

PS, Check the pots in the office. Make sure they are all the same size. Decanters come in 3 sizes; 10 cup, 12 cup (standard), and 3L (3 litters). Check the decanter brand as each brand is a bit different in size. All metal decanters are usually very small (8 cup). What ever size you use, just make sure they are all the same.

We have a Bunn vpr pot and we empty it in the fall and restart it in the summer. How much water needs to be added and how long do we wait until the water is ready? Also once we made a pot do we just need...


The bunn VPR is a gravity brew system what you put in if the tank is full is what you will get out. So pour water in until it flows out the sprayhead, then turn machine on, when it heats up fill up a carafe with water (1.9Liters) and put in your filter with water and brew. It is a good idea to pour water in every morning to make sure tank is full especially if you are not using brewer on the weekends.

How do I get the BUNN VPR coffee maker to brew a pot of coffee? There are two switches; one for the lower, and one for the upper warmer. Do I first have to fill the tank ALL the way before it brews? Please...


This brewer has a 2 1/2 pot reservoir. You should NOT plug in the brewer before the reservoir has been topped off. Pour 3 pots (one at a time, every minute or so) through the screen with a pot under the filter basket. Wait until the water flows from the basket and only then is it safe to plug in the brewer. The reservoir holds HOT water until you are ready to brew and then, by pouring in a pot of cold water, you will be able to brew.

I have a Bunn VPR, it brews fine for a couple pots


Try running a quarter-pot 50/50 solution of white vinegar and cold water through to clean out calcium deposits in the pump system. Use a clean filter to catch the pumped debris. When pumped through, let cool somewhat, and reuse the cold mixture again twice more. Pour out the vinegar solution and run several cold water loads through to wash out the taste. Hope this helps!

Not sure how to use it. Can you only pour one pot of water in at a time and does it brew automatically?


There is a one and a half gallon holding tank inside this coffee maker, you can maybe brew 2 pots one after the other but then you need to give it time to recover. When you pour hot water in it pushes hot water from the holding tank out the spray head...hope that helps :)
