I fill the Brew and Go with water (ground coffee is in, etc), push start button and then is shuts itself off after about 20 seconds (it makes the gurgling sound like it does at the end of a normal, successful cycle). Sometimes, by the third try, it will go thru the complete cycle. I suspect is might have something to do with the small plastic ball at the bottom of the reservoir?

You should call your vendor for service on any commercial brewer. (Especially if it's on loan from them)
*** the following is for information only as all repairs should be performed by a qualified tech.***

The CWTF has a start switch activates the timer (analog or digital) board which turns on the water feed to the brew tank. This forces previously heated water out and sprayed over the ground coffee in the brew funnel. Coffee then drips into the decanter.
* It's not often this momentary brew switch goes bad even though it's pressed many times a day.
* Check the on/off switch. Most models will light up when switched on.
* Check the timer. Digital timers tend to be sensitive to electrical storms. Analog timers have a dial and are more tolerant of electrical surges.
* Check the water fill solenoid. Should be a definite click when activated. Water filling sound should be very clear.
* No water flow then check the water supply line if it's on.
* Final; this brewer needs service. Call your coffee vendor for advice.

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*)

You should contact Bloomfield to find your local Bloomfield Service vendor. You will need them for parts and/or service.

The start switch activates the timer (analog or digital) board which turns on the water feed to the brew tank. This forces previously heated water out and sprayed over the ground coffee in the brew funnel. Coffee then drips into the decanter.
* But since the water line was not connected then the buzzing sound is just the valve opening.
* This brewer has a tank that needs to be filled PRIOR to powering up as the heater element usually turns on as soon as it's plugged in. The thermal fuse(s) will blow if tank is not filled. Once filled and powered up. Wait 20 mins then set up a coffee funnel and decanter. Slowly pour in 1 pot of water into the top opening. Do Not splash or over fill! Water should come out of the funnel and fill the pot (full). If it's not hot then the element is not working and this unit will need service.
* Check if there is an on/off heater switch on the back or side. (some are 'Vacation' switch) Turn on and wait 20 mins for another pour over brew. If it still does not heat then the limit fuse(s) are blown.
* Check the on/off switch. Most models will light up when switched on.
* Check the timer. Digital timers tend to be sensitive to electrical storms. Analog timers have a dial and are more tolerant of electrical surges.
* If you do get a good heated brew then continue to use as a pour over or hook up the water line to the brewer. (usually a 1/4" copper line with a flare or compression fitting.)
* Check the water fill solenoid. Should be a definite click when activated. Water filling sound should be very clear.
* No water flow then check the water supply line if it's on.
* Final; this brewer needs service. Call your coffee vendor for advice.

Call Keurig 1800 Cup Brew

2 years old I would pitch and buy a new one.

Cleaning generally won't help a machine that does not work.
Heating element has probably burned out.
(I am not talking about the heating pad for the carafe!)

For future reference for all the coffee drinkers out there:
Simple quick way to clean a drip coffee maker is use Vinegar.
Let it brew through the system as you would water.
Discard and run fresh water through the system to clear out the vinegar residue left behind. (Make SURE the system has cooled first before running the fresh water through!)

For those that have hard water and the coffee tastes funny.
Try a small pinch of salt in the filter basket ON top of the coffee grounds. This will soften the water and hopefully take the bitter taste away.

Guess it is possible large enough calcium deposits could block the hole in the holding tank to prevent the water from percolating to the filter basket. You may wish to check this before tossing. Last minute thought before pushing the post button.

Good luck!

Hi Try reprogramming the machine. Push and hold the button for the coffee you want, but hold it all the way through the process. Don't release the button until you get the amount of coffee you want for that button, then release the button. That should get you the same amount next time. You can do this for each coffee button. If that doesn't fix it, then you might need a new flow meter.

Remove the brew basket and water defuser (sprinkler head) it should come off with a 1\2 turn.
Place your measuring pitcher or empty pot in place.
Turn the main power switch off in back of unit.
Press and hold the Brew(full pot) button.
While holding the Brew(full pot) button turn the main power button in back to on.
Once the red light flashes over the Brew(full pot) button release it, then press it once to start the brew cycle.
Let it flow until desired level in pot or measuring pitcher.
Press the Brew(full pot) button once to Stop.
Press the Brew(full pot) button once again to lock the settings into memory. Memory will store the settings even if machine is unplugged.
Half pot button is automatically set.

This happens when the machine needs cleaned. Fill coffee maker with white vineger instead of water. Turn grind off, make sure empty pot is in place. Brew a pot of hot vineger. Repeat. Brew a pot of hot water. Repeat. This process removes mineral buildups inside machine. If you have access to filtered water, start using that to brew your coffee. I do and probably do this process 1 per 6 weeks.

I have a cuisinart model dgb-600bc coffee grind & brew, didn't have a manual with it when purchased, plugged in it & hit the on button, lights up when pushing in on it, but let it go & it stops, but doesn't brew nothing. HELP -

Could you please advise how I obtain a manual for a Saeco Magic deluxe
