Bunn G9 Retail grinder usually has a large "Chaff" plate located inside the top portion of the discharge port. There is usually a handle connected to this plate to allow the last bit of grounds to fall out of the chute. It looks like a 'trap door' that swings open and close. You will need to replace it if it's missing.
* Some places use a bag clip to attach a coffee bag to the chute so all the grounds can drop into the bag. This clip (with a small metal chain attached) also helps with the static electricity.

    *** You should call your vendor for service. The following is for information only ***

    I'm guessing there is a funnel under the grounds discharge port and your not using a bowl to collect the grounds. (some places do this to measure their own amounts to adjust brews.)

    * There is a square thin metal "chaff plate" at the top of the discharge port. With a flash light look up into the chute. you should see a blackish/blue steel flapper (like a playing card in a bicycle spoke) Do NOT stick your finger up there! Yes, there may be exposed grinding plates that are sharp!

    * if it's not there or broken (it's steel and very brittle) then it needs to be replaced by a service tech. It's a bit tedious to replace and in a very cramped area.

    * Grinding generates a lot of static (even in Hawaii with 80% humidity) so expect some splatter or at least grounds clinging to the sides. It will settle after a while. Many places leave the funnel in place with coffee already ground in the funnel so they don't have to wait for the grinder.

SOURCE: Bunn coffee drips slow

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: Bunn coffee maker leaks all over the counter. What

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!

SOURCE: Coffee grounds overflow out of basket into top of coffee pot.

Coffee overflowing onto the counter is a common complaint found in response to many automatic drip coffee makers. The following are potential solutions that can be used to rule out "operator error" vs. a defect or malfunction:

1. Do not "pack" or otherwise overfill the cone/basket with grinds.
2. Ensure you are using the correct grind for an automatic drip coffee maker, neither too fine nor too course. (See instruction manual.)
3. Do not overfill with water. Use the carafe to pour water into the reservoir. This is because a "cup" in coffee terms is defined as 6 oz, not 8 oz. Note: Some coffee makers define as little as 5 oz as a cup.
4. Make sure the filter cone/basket clicks into place and that the carafe is centered and pushed all the way in.
5. Try a permanent filter rather than a paper filter or vice versa.
6. Only use the correct permanent or paper filter (see manual).
7. Verify that the Pause 'n Serve button isn't sticking. If it is activated too long the brew will escape over the top of the cone/basket. This may be more apt to happen if the alignment of the carafe and the basket is incorrect.
8. Clean your machine with vinegar or as instructed by your user manual at least three times per year, more if your water supply is hard. A properly cleaned machine is less likely to suffer a burned out heating element, to take too long to brew, to produce "off" tasting coffee, or to clog and overrun the filter basket as the water runs through the grinds.
9. Ensure that the coffee machine is sitting level on the counter.

SOURCE: Coffee grounds overflow

Tressia,
An overflow can occur when using certain brands of coffee that are finer ground or using a water softener, bottled water, reverse osmosis, or filtered water. If you will call Bunn Customer Service, you can get a flow restrictor sprayhead which will eliminate this issue.

My Bunn coffee pot seems to pour out so quickly. The grounds come out the back and all over the counter and in the coffee.

if the coffee is ground too fine, it'll take longer to brew through. either grind more coarse or call bunn for a flow restrictor (800) 352-BUNN (2866)

I have a Bunn G92T HD Dual Hopper Coffee Grinder, and when I put the basket underneath it and grind coffee, the grounds spray too far and get behind the filter in the basket. Is there a way to fix that?

If you are using a plastic basket, try to get a metal one, that will help with the static and or the dechaffer springs need to be replaced on the grinder.

We have a 2 month old bunn coffee maker. worked fine now coffee is taking 10 minutes to brew

Sounds like calcium build up, You need to descale the machine.

If you look at the grounds on the basket, After the brew cycle is over there is like a hole in the center of the grounds. This happens when there is calcium build up in the tank, tube and or spray head. And takes forever for the brew cycle to end.

Follow the instruction on your manual to descale the brewer.

Less than one year old. Takes 10 or more minutes to brew a pot of coffee. I have followed cleaning and deliming instructions three times. Did not help.

Hello. the problem is the little sprayer that sprays water into the coffee grounds. They get clogged with coffee oil and coffee grounds. Unplug the machine, tip it upside down in the sink so the water doesn't go everywhere and use a straight pin to clean out the little holes of the spray nozzle. That nozzle should unscrew, which would make it easier to clean. When you are looking at the nozzle, unscrew it by turning it counterclockwise. Joe

Grounds splash from basket into carafe

My brother has a Bunn that does the same. I think the coffee filters he is using are too short. If you think this might be the problem too, try an internet search for Bunn coffee filters. Hope this helps!
