Question about Bunn Coffee Makers & Espresso Machines
Im assuming you tried it more than once and the tank is full when you start? If your doing manual fill pour over the timer has nothing to do with that. If it's plumbed with a water line, before you start changing your timer for the brew cycle, first try the easy fix which is unscrew the spray head. it's the piece the water comes out to the basket. Take the cleaning spring tool and rotate it as you push it thru the tube you just unscrew the spray head from. As your pushing it thru it has two turns in it . Just rotate and push until you have gone thru the second one and then it's clear to the water tank. Unfortunately this doesn't always get it unplugged. Where the tube goes into the water tank there is silicone hub on the part that's in the tank and it can keep some of the lime buildup from being removed. You will have to take the top off and remove the tube to clean it if that happenes. Dont forget to unplug it first. The other common spot for a restriction is where the water leaves the pan your pouring into. You need to remove the pan to get the spray tube out anyway so look also at the big nut that holds the pan onto the tank.sometimes the hole will plug in the center .

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'm going to presume that your brewer is a VPS series pour-over brewer. This problem can be caused by several things, so I'll list the most common ones.
1) The on/off switch for the lower warmer could be burnt out.This switch also operates the heating element.
2) The high limit thermostat quite offen blows on the older VPS brewers. this is a small unit held down to the top of the tank and has 2 wires voming to it.
3) Look for burnt-off wires. These models sometimes burn off wires on the top of the heating element.
4) If none of these work, then your problem will be your heating element itself.
Parts for these models are readily available from your local Bunn repair shop.

Hello. I would like to suggest that you pour in water, with a container under the funnel, until water does come out, it sounds like the water has just evaporated too far, and it requires more than a pot to bring it to the top. In the future, if you do not use it for a day or more, you need to unplug it, or just pour a pot of water in to keep it at level, as this unit heats all the time it is plugged in, and can actually evaporate all the water away, blow the element, damage the thermostat, or worse permanently damage the unit.
here you can find the user manual:
Hope that helps, and thank you.

It may not help but won't hurt; put a couple of cups of plain vinegar into the water chamber, turn on briefly until it starts to pump, then turn off and leave overnight - at least, if not longer. The mild acid content may clear some lime buildup.
