CHECK THE BLACK WIRE COMING OFF THE BOTTOM TERMINAL OF THERMOSTAT FOR VOLTAGE, IT SUPPLIES POWER FOR THE WARMER SWITCHES. THE 'READY TO BREW' LIGHT IS PROBABLY A BAD BULB.

How do food warmers work?


Usually food warmers consist in trays of food sitting in a bath of boiling hot water. The hot water heats up the tray, keeping the food warm.
Most domestic food warmers are electrically powered.

I just get bunn VPS it is and work very good


The switches are for the "warmers" only. The brewer has a reservoir the keeps water hot and ready for brewing. When it is not re-heating water (after brewing) it has a "keep warm" heater that is low voltage and keeps it ready to go.

Reservoir heats but won't dispense


If you are pouring water in the manual brew basin, then check the sprayhead holes, then the spray tube, those could be blocked. If using the auto brew, check the solenoid and or brew switch.

Coffee not hot enough


hi elite 288! have you tried pre-heating your coffee cups? i fill w/hot water, then set them on cup warmer until i brew coffee (dump out water & slide cup under spout at last moment) and i do my frothing of milk before brewing espresso. also, have you allowed adequate time for machine to warm up/run just water through machine: after it indicates it's ready to go, hit the brew button & allow about a 1/2 cup or cup of water to run thru, warming up the brewhead. when ready button again lights up, brew your espresso. if this doesn't get it hot enough for you, try descaling your machine (you can look online or in manual for how to do this). since you have a refurb unit & heating element may not have been replaced, it could have some build up on it causing it to heat up all the water less efficiently. if this doesn't work, you may need to have the place you purchased it from diagnose and repair. good luck!

I did the initialization as per the directions and the water was hot. When I make the coffee, the warmer button will not come on and the coffee is cold. I turned on the vacation button for 15 minutes...


Sounds like something is miswired from the factory. Note that the tank heater switch on most home brewer models also acts as the "master" power switch. If the tank heater switch is not on, the warmer switch will not work, either - this is normal. Under normal conditions, the tank heater (or vacation switch) should always remain on, except if you are leaving on vacation.

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.
