Bloomfield Coffee Maker not brewing

Be sure spray disk and brew gasket are properly installed in the
brew head.

Be sure the water supply is properly connected and the water
supply valve is turned
ON

Be sure the WATER TANK IS FILLED
BEFORE plugging the brewer into a receptacle, or otherwise
connecting brewer to electrical power
THE WATER TANK MUST BE FILLED

Place an empty decanter under the brew head. Lift
the pour-over cover then pour warm tap water into the pour-over
opening until water flows from the brew head. When water stops
dripping from the brew head, empty the container.

Once the tank is full of water,
connect the brewer to electrical
power. The heating elements will begin heating the water in the
tank.
When the water has reached the proper temperature, the
"READY To BREW" light will glow. http://www.cdccoffee.com/pdf/bloomfield-8571-8572-user-manual.pdf

Who owns the brewer. Usually the OCS supply does the maintenance. Office Coffee Systems sell and service the brewers...the service if for free. Does it have a label on the side or anywhere. If it is overflowing, is it out of the brew basket in to the pot?...There are a couple reasons for that. Is it a water line model?. If it is a pour over, it is human error. If it is a water line model it is probably a leaky inlet water valve. http://www.pamasco.com/bloomfieldsolenoidvalvesandrelatedparts.aspx

VPR is a pour over "Volume Displacement" brewer. Required to completely fill the inner tank and heat prior to using brewer. BEFORE plugging in unit, water must be poured into upper tray and with brew funnel and empty pot in place. Keep pouring water into top fill tray until water drips out of brew funnel. Plug in VPR and allow it 15-20 mins to heat up. leave the pot as there may be additional water dripping. Remove power if there is any water spilling out from other places like the top pan cover or bottom of machine. With the initial heating done, take a full pot of water and slowly pour into the top filling tray. HOT steaming water should come out of the brew funnel to fill the (empty) pot. Prep is done and the machine can be used to brew a pot after 10-15mins of reheat time.
*** the machine you have needs to be checked for leaks in areas mentioned above. Water should only come out of brew funnel (if not present then the brew head or if that is missing then the brew pipe. All will need to be replaced prior to brewing.) Leaking under machine is an indication of leak(s) in pour tray,tank,tank cover, gasket, probe gasket. This machine like any used equipment should be checked out by qualified tech prior to use. Be aware that coffee vendors sometimes rent or loan brewers to customers.

You should contact Bloomfield to find your local Bloomfield Service vendor. You will need them for parts and/or service.
*** the following is for information only as all repairs should be performed by a qualified tech.***

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.
* 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.

I will assume that it is a pour over brewer from your statement, so the only thing that comes to mind is the thermostat not turning off the elements and the water is boiling and coming out the brew tube. You can try to adjust the thermostat first if that does not help then you might have to replace it.

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.

Hi, Get 2 pots place one under the spray head with the filter cone in....now fill the other coffee pot and start to pour water through the lid top front...keep pouring water through (about two and a half pots) until water starts to pour through the cone....now the tank is full plug her in and turn on the power switch at the back and also the front if there is one....place filter in cone..put coffee in filter...pot on burner...wait about 25 minutes until water in tank is hot...when light on front comes on pour another pot of cold water through the top and you will get a pot of hot coffee in bottom....I also think this machine can be hard wired into water main....get plummer to hook up...follow same procedure but instead of pouring water through top for coffee..hit brew switch. if it poors too much of too little you will find a timer in the machine you can adjust to allow more or less water...hope this helps.

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.
