Coffee pot just would not brew this morning, though it worked fine yesterday morning. I emptied it and started over 3 times. The lights come on but that is all that comes on.

Sorry this brewer is usually set up for a full pot brew. I have reset this for a small (but not half) pot brew as the customer wanted to use a metal carafe (with their own logo). I also tried once to get it to half pot brew but it can get tricky if you actually brew twice to get a full pot (in the same pot).
* there is a siphon action that starts once the boiler tank gets filled to a certain point. From that point it will continue to flow until the boiler is emptied to the level that stops the siphon action and leaves enough water in boiler to reheat for the next brew. Achieving the siphon point may be a larger volume of water for 1/2 a pot but may work for 3/4ths a pot. The 1/2 way mark may be affected by the brewers "level" while placed on a table or sagging in the middle of a weak table.
* Usually if you want a smaller brew then go with a smaller brewer. Though there is a hot water tap that will give you 2-4 cups of hot water (it gets tepid after that) which you can use for the "Mug" style brew. But it does get messy.ukeboy57
* Final, If you don't mind a little more than 1/2 pot brews then ask your vendor to adjust the machine for you. Though a reminder NOT the double brew in the same pot as it will overflow.

VPS/VPR (VP17-3 are the same except it has 3 lower warmers) are pour over brewers. Like the 12 cup brewers you find at home, they need to be filled with 12 cups of water (a full pot), heated and then peculated over the coffee grounds and collected in a decanter.
BUT there is one main difference! The VPR and similar COMMERCIAL coffee machines are quick brewers. They usually have a pre-heated pot of water stored inside the machine.
* VPR's and similar machines REQUIRE a pre-fill and heating period prior to brewing. This means it's sitting on a level table and filled with water until water sprays from the brew head. At this point the unit is plugged in and the heater is turned on (there may be some water discharge from brew head as the water expands). Ready light will come on in about 15 mins.
* To Brew; Place coffee grounds in filter, place in funnel and brew head, clean empty decanter under funnel, slowly pour one full decanter of water (cold or hot) into brew tray. Do not overflow tray. Allow water level to sink before adding more water. Only fill with one pot as an equal amount will come out the brew head and funnel.
* Make sure the decanters are all the same size. do not mix a 12 cup pot with a 10 cup pot. One will over fill and the other will under fill. Make sure they match (in cup volume) FYI; Thermo Air pump pots are usually bigger than one pot. Typical filling only to 3/4th of the container. (I think most are in 2.5 to 3 liter sizes)
* If your not getting a full pot then the brewer was partially empty. The second brew (if done within the next hour) should come out full.
* If your still not getting a full pot then the water is leaking or is boiling off. Does it always steam from the top? Thermostat is shorted. Unplug the brewer and call vendor for service.
* Final; If your unplugging when not in use. Then follow the Pre-heat instructions mentioned above prior to plugging the brewer back in. If the tank has been emptied at night or dried up after an idle week. Then there is a chance you may over heat and blow the thermal fuse. Or at best have a half pot short brew as the water dried up.
* Note leaving the brewer plugged in without brewing daily is not a good idea. The water evaporates and eventually drys out the pot. Takes about 1-2 weeks but it does blow the fuse(s) and the unit will need service.
* Final; Follow the Bunn set up and care instructions (manuals from Bunn.com for down loading. *FREE*)

All coffee makers do this over time from calcium, lime, and mineral deposits building up inside the tubes and heating coil. Fill the reservoir with a 50/50 mixture of water and white vinegar and run a normal brew cycle, turning it off and on if necessary to completely empty the reservoir. Repeat this 2 or 3 times with fresh mixture of vinegar and water until it brews the reservoir empty without the need to cycle the power. Follow this procedure with plain water 2 or 3 times to clean the vinegar out. This should get it working like new again. It's best to use distilled water for brewing coffee as distilled water does not have the minerals that regular tap water has and therefore will not clog up the machine.

Check programming.This is very simple;turn switch on and hold brew switch until you here 3 clicks to start brew timer .When desired level is reached turn off on/off switch on front panel to set brew time.Check brew level now.

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!

Make a 1/2 pot 50/50 mixture of cold water and white vinegar then run it through the machine in normal brewing fashion. Place a clean filter in the brewing cup to catch the white deposits that are removed. Allow the mixture to cool, then repeat the process several times while using the same filter. Finally, run several pots of fresh water through to work out the taste of the vinegar. Repeat whenever the brewing time seems to be excessive.

check water heater

Cuisinart replaced the coffee maker. It was still under the 3 year warranty so Cuisinart told me to take it back to one of the stores that sells Cuisinart coffee makers because the store I bought it at was going out of business.

These macines have an internal water heater that should be clened periodicly (monthly per manufacturers instructions but I do it quarterly/semianually/when it gets noisy :) ). The machine will have to be disasembled to do this since the tank will have to be flushed when you do this to get the chemicals out of it (vs running a pot of vinegar through your Mr. Coffee machine at home), Depending on how much scale has built up in the tank this could take several cleaninings. Scale deposits can over time impair/damage the heater or thermostat but replacement parts are cheaper than a new machine and the machine will outlast and outperform a standard coffee maker. BTW, my 8572 3 burner was built in 1972, I bought it at a flee market for $25 10 years ago put $100 in parts to get the push to brew and hot water on tap working again and it made two great pots of coffee this morning.

The first time you use the machine you need to make sure it is full of water - before you plug it in and turn it on. Put an empty coffee pot under the brew basket and fill another empty pot with clean cold water.

Pour the water into the coffee maker. If water comes out then you can plug it in and turn it on. The water heating tank holds about 2-1/2 pots of water so if your machine is empty you will need to keep adding water before you turn it on otherwise you may burn up the heating element.

After the green light comes on - indicating that the tank is hot you can brew a pot of coffee. This machine is meant to be left on all of the time so it is always ready to brew. If you choose to turn it off when not in use, you will need to give it about 10 minutes to fully heat up the water before you brew.
