If all passages are not plugged up it should flow through with or without heat in the tank.

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.

open the cover on the brewer- depending on your model, it could be the front or the back cover. look for a brew timer dial. turn this up slowly, running a brew each time to see if you now have a full pot

I have a bunn coffee pot that i purchased at KOHLS The serving pot leaves a mess from dripping everytime i go to . please replace the serving pot. Kohls WILL NOT REPLACE TOLD ME TO CONTACT YOU.


* Most decanters are made of tempered glass and unless cracked it should not leak.
* Make sure the two pots you are using (one to pour one to brew) is the same size. Check by filling one then pour into the other. If they don't match then get a matching one.
* Most overflowing pots are caused by over filling brewing tank. This can be caused by re-pouring additional water into the brew tank. (automatic brewers may have a leaking water valve - call your vendor for service)
* Partial brewing (taking coffee from a brewing pot) and then putting in more water.
* Removing the pot BEFORE it stops dripping. It leaves a puddle of coffee on the warmer plate
*Over filling the water tank. Most times the extra water will spill out the back. But some may overflow into the basket area then the warmer plate.
* Follow the MFR brewing instructions for filling.
* All brewers should stop water drips after brewing. If you get a constant drip AFTER brewing then have the brewer checked or replaced. Call your vendor.

PS: I've noted that you don't mention the brand nor model of the server you got from Kohls so I'm guessing it might be a dispenser or even a bunn dispenser which is different from a decanter as it has a serving spout. You find these at banquet halls where it's dispensed from a small faucet. You can find similar faucets from bunn.com or most restaurant supply stores as it's a very common item. Amazon.com has them too. the part tat leaks is the rubber boot or worn spring. best to buy the whole faucet and keep the old one for parts as needed. amazon link:

My bunn will not pump any water into my pot the water is hot the plate is hot but want pump


* If this is a pour over (VPR, VPS, etc.) then you must pre fill it then pour in one pot of water to get one pot of brewing hot water out of it.
* If this has an external tank of water then it must be filled and make sure the float sensor works and pops up to indicate a filled tank.
* But most likely this is a CWTF, CW, or larger commercial brewer that has a plumbed in water line. If this is the case then the tank must be pre-filled and heater turned on. usually done by the vendor or installer. It should have been tested and brewed to check water level of brew. Follow the brewing instructions.
* Still not working? Call vendor for service. It could be timer, brew switch, water level board, water fill valve,brew valve. all need check and service to replace as needed. Many larger units have high voltages so call the tech to be safe.

Why does coffee come out while pouring in water its a bunn 10 cup coffee maker


The Bunn has a little stopper that closes the water drain port in the reservoir while the lid is open. You can see a little white plastic pin protruding up out of the grate with the lid open. When you close the lid, it pushes on that pin which causes the stopper to lift off the drain port, allowing the water in the reservoir to enter the heating tank.

If water is entering the coffee basket BEFORE the lid is closed, then something is wrong with that little stopper. It may have a chunk of debris on it preventing it from sealing, or it may be deteriorated, torn, disconnected, etc.

Only way to know is to remove the the screws in the grate and pull the top off exposing the reservoir, and the stopper assembly. The little plastic flapper disc should be seated in the reservoir drain port. It should be relatively flat (not wrinkled) and covering the drain port completely. Test it by pouring some water into the reservoir. If it drains out without you activating the stopper, then a repair is needed.

Move the lever up and down and check its operation. The arm must move freely and close when released. There should be no dirt or debris on the sealing surface of the flapper nor on the sealing surface of the drain port. Gently clean with vinegar as necessary. If the seal is damaged, then a replacement is required.

It only makes 1/2 pot when I pour the water in after sitting over night some times it takes 2 pot of water or more to make a full pot


I recommend slowly pouring in about a half a pot of cold water without coffee in the filter basket 5 or so minutes before you brew in the morning. There are 2 good reasons to do this-
1. Overnight you are having some evaporation due to the fact that your Bunn brewer has a reservoir that keeps a couple of pots worth of water at brewing temperature... a better temp than most "home" model brewers. This will top off the reservoir and you will not "short pot" except for the amount that the grounds themselves hold back.
2. Also overnight, due to the fact that the water is kept hot, the oxygen can dissipate from the water in the tank. Topping off with fresh water will mean a fresher first pot.
The Bunn brewers have a low wattage/keep warm heater so the actual heating element isn't doing all of the work over those long periods... it only kicks on when the temperature in the reservoir drops considerably (like after brewing). Be sure to let the brewer heat back up before brewing (you will hear it stop heating)
Hope this helps.

When i make coffee sometimes the water that comes out is cold or luke warm


The brewer has not had enough time to reach its operating temp (usually 7 mins after a brew cycle). If that is not hte case then the machine needs to be descaled.

Coffee is in water is in nothing happens


You may not have enough water in the tank.
Follow these steps

1. With the coffee pot unplugged, fill your resevoir/tank until water begins pouring out of your sprayhead and brew basket.
2. Wait for the water to finish dripping then plug in your Bunn.
3. Let your Bunn warm up for at least 8 minutes.
4. Run a test cycle with clean water, remembering to use the water pitcher provided for this purpose, while leaving your empty pot on the burner beneath the brew basket.
5. If your cycle completed, and your coffee pot is filled to the desired level you are ready to make coffee.

Remember that these Bunn models have no water filter2_bing.gif installed, so, the cleaner the water the better tasting the coffee.

Bunn coffee maker


It sounds like you have a pour over model and the problem is the tank isn't full. Turn the machine off (or unplug it). Put a pot on the warmer like you are going to brew coffee. Pour clean cold water into the top until it starts coming out the sprayhead (above where the coffee grounds go). Now plug it in and turn on. Let it heat up then you can brew.

The way your machine works is that there is always about 2-1/2 pots of water in the tank. The water you pour in to make coffee is actually pushing the hot water in the tank out. So, if you don't fill the tank before using it, you may be hurting the heating element since it isn't totally submerged in water.

The Bunn coffee machine has an internal tank used for holding approx three potfulls of water at just below brewing temperature. When you add water for a potful, the thermostat senses cold water and starts the brew heater. The water level inside the tank comes up and goes through the sprayhead. This "surge" of water, that you call drips is normal. The hot water stratifies to the top of the tank, just like an electric water tank in a house. The internal pot heater kicks in and boils the water already in the tank, raising the water level in the siphon pipe to the sprayhead until the reservoir under the add water opening is empty.
