My coffee maker reads err rr 2 and then err 4

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

Vinegar is really not good for cleaning coffee machines.

You should rather use acetic acid.

1) put 4 cups of water into the coffee makers tank.

2) pour 4 cups of acetic acid also in the coffee makers tank.

WARNING !!! ALWAYS pour ACID into WATER and NOT the opposite !!!

If you pour water into acid, it can explode and cause severe damages !!!

3) Let it run through the coffee maker.

4) pour hereafter water in the tank and let it run through 2 times.

If this does not help to decalc your coffee maker, it is time for a new coffee machine.

Good luck

Found the answer in an Amazon review. Place a small bamboo stick in the water sensor located in the resevoir. The ERR code disappears and you can brew as normal. If you leave the stick in, measure water carefully as there is no auto shutoff.

Are you sure 8 cups of water is a lot to LOOSE it has to be somewhere i am used to loosing 1/2 cup in the grounds if i make 8 or more cups i have 2 of these coffe makers one in each house the only times i ever loose more is when the filter isnt properly seated and it flows around it and makes a major mess get your coffee maker into a good light and pour water into the filter(coffee maker off) with the carafe out fill it about 1/2 way no water should leak thru then slip the carafe into place the filter should empty if the water flowed when the carafe was out your filter basket and holder arent seated or the valve on the bottom of the holder is clogged and/or held open

The tank inside holds about 2 and a hlalf pots of water. Once the tank is full, whatever you pour in will come out. The unit has to be plugged in to make coffee. Leave a pot under the brew funnel and pour a pot of water in. If nothing comes out within a minute, pour another pot of water in. Still if nothing comes out do it again. This time for sure water will come out. It will take avout 10 minutes to get hot enough the first time it is full to make coffee. If you have a thermometer, the water should be about 190 degrees F to make coffee correctly.

my brewstation did the same thing. I put the water in the proper area, and it still stated "pour water" so I removed the water, took off the coffee basket, removed the coffee "bucket" and laid the coffee maker on its side, on top of a towel. I came home later that day and tipped it completely upside down (removing all possible water from the system)

To my surprise, some coffee grounds came out with it. Apparently, if any grounds get caught in siphon system, it can jam it shut. Then the system is not able to remove water from the reservoir, and thinks there is no water.

Hope this helps

Well they don;t give these away for sure. Lets see if we can help you out. ? are you over filling it.This happened to me because I was reading the fill line wrong. {got new glasses} . If not may be you could try makeing less. But if only 1/2 cup comes out and no more, that wouldent indacate a leak in the tank, if there was it would all leak. Try backing off on the coffie and water, and see if it still leaks. if it does get back to me. DFD

Vinegar/water cleaning is a good idea, but it won't necessarilly solve funny-tasting coffee. First, replace your charcoal water filter - you can get the Cuisinart brand-name replacements at Lowe's, Bed/Bath/Beyond, or Williams-Sonoma in most areas.

To do the vinegar/water cleaning, just pour 1/3 caraffe distilled white vinegar and 2/3 caraffe water into the water reservoir and brew it like it was regular coffee - I would simply bypass the self-clean function if your Cuisinart has one. Repeat up to 3 times, using a fresh batch of vinegar each time.
(if you have the caraffe-less DCC-2000, then just pour in 4 cups vinegar and 6 cups water).

Then run a full cycle of water. Then run a combo of 12 tsp lemon juice and 12 cups water (or 10 tsp and 10 cups water) to improve the taste.

On your next batch of coffee, use bottled water just to rule out any possibility that your local water supply may be contributing to funny-tasting coffee.

Now your coffee should be tasting fine again.

It sounds like you have a pour over model and the problem is the tank isn't full. Turn the machine off (or unplug it). Put a pot on the warmer like you are going to brew coffee. Pour clean cold water into the top until it starts coming out the sprayhead (above where the coffee grounds go). Now plug it in and turn on. Let it heat up then you can brew.

The way your machine works is that there is always about 2-1/2 pots of water in the tank. The water you pour in to make coffee is actually pushing the hot water in the tank out. So, if you don't fill the tank before using it, you may be hurting the heating element since it isn't totally submerged in water.

I had a similar problem with Err 1, Err2, and Err 4. To resolve Err 1, if you have room, remove the coffee filter and coffee, pour more "warm" not hot water into reservoir. If you have 4 cups cold water add 5 cups warm. Then start coffee maker and let it run thru. Then drain coffee pot and start over to make coffee with tepid water. Err 1 indicates the coffee maker temp sensor is too cold from room temp or water temp.
Err 2 is a result of cleaning. First question "Did you remove the charcoal filter?" The charcoal filter can be removed form the filter stick by prying two tabs away gently and removing the filter for removal. The filters can be purchased @ www.Kitchenaid.com
One pot run thru with descaler can loosen scale and make sensor go "blind". Just run a full pot of clean plain water thru one maybe two times. A pot solution should be a solution of 1/4 pot WHITE vinegar, 3/4 pot clean cool water. Run this thru once, then two clean pots of fresh water as if you brewed a pot of coffee. NEVER USE CLR WITHOUT RUNNING NO LESS THAN THREE CLEAN WATER POTS THRU MAKER!!!! This is so you can continue to enjoy drinking coffee, nothing like a cup cleaning you out!
Err 4 is simple, you have a stuck button. Unplug maker and gently press each button making sure they aren't stuck in.
