When I pour water into (empty) pot to fill. Bunn coffee maker

Your pour over coffee brewer has a reservoir that holds more than a pot of water. First thing you need to do is turn off the machine. Then put the empty coffee pot on the burner. Then take another container and fill it with fresh cold water and pour it slowly into the coffee maker until it starts to come out into the coffee pot. Stop pouring in water.

Now turn the machine on and let it heat up. Now you can brew normally. The reservoir has to be filled before you turn it on or you will end up eventually burning up the heating element.

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.

You should be able to pick up a replacement/new pot at your nearest Restaurant Supply store. Make sure you get a 64 oz./ 1/2 gallon pot.
Before plugging in your brewer, unscrew the sprayhead located just above where the filter basket sits and replace the basket, pour 3 pots of cold water through the opening on the top if the brewer is empty. This brewer has a reservoir that holds about 2 1/2 pots of water at brewing temperature when heated. Make sure you put an empty pot under the filter basket after pouring in the water. Water will flow from the brew basket when the reservoir has reached its capacity. Once water flows you can then plug in and energize your brewer and replace the sprayhead. It will take about 15 to 20 minutes for the brewer to reach brew temp, you will hear the heating stop. Put an empty filter and a dose of coffee (I recommend starting with a heaping measuring cup of drip ground coffee) into the filter basket, lightly shake it level, replace the basket and pour through 1 full pot of COLD water in the top. For best results pour the brewed coffee into a pre-heated thermal server if you plan on holding the coffee for more than 10 minutes or so.
Enjoy!

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.

This machine has a reservoir that holds about 2.5 pots and keeps them at brewing temperature. Therefore you should pour in 3 pots (with a pot in place under the filter basket) until water flows from the basket. Then, and ONLY then, it is safe to plug in the brewer. If you plug in the brewer BEFORE filling the reservoir you will burn up the heating element and will have to have it replaced.
After the initial filling and heat up (about 20 minutes) you are ready to pour through a pot of COLD water through and brew.

The machine is always on, so it is never full the first time you use it on monday. Try this before you use it on monday pour in a full pot of water in the brewer and put an empty pot under the head. Wait about 7 minutes, the machine will fill the tank and then be ready for brewing coffee.

before plugging in place your empty filter basket in the coffee maker and place a pot under it. Slowly pour in two pots of water using the pour pitcher. Now you can plug it in. it'll take 15 min to heat up first time . when you brew your first pot leave your water level a little short,because the water will expand (only the first time)

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.
