You need to advise the model .. but assuming its the CVA 40XX series ... the frist thing to check is the dispenser which has the two pipes comming out of the bottom. This can get coffee residue build up which usually causes 1 or both pipes to have reduced coffee flow. Indication that this is at fault are if the flow is uneven between the pipes or if coffee flows down the outside of dispenser. You can chck this pipework for blocages by openeing door and blowing air though the pipe extending on inside of door. The the dispenser is blocked you need to remove from rear of door and then clean out thoroughly in running water. If this pipework is not and

You need to advise the model .. but assuming its the CVA 40XX series ... here is what I would do;
1. First check is the coffee dispenser on front which has the two pipes coming out of the bottom. This can get coffee residue build up which usually causes one or both pipes to have reduced coffee flow. The indication that this is at fault is if the coffee flow is uneven between the pipes or if coffee flows down the outside of dispenser. You can also check the dispenser for blockages by opening door and blowing air though the pipe extending on inside of the door. The air should flow through easily. If the dispenser is blocked you need to remove from rear of door and then clean out thoroughly in running water.
2. Next check the pump and water path. The pump for the coffee is also used for producing hot water. So if the hot water is working normally then you can rule out the pump. If you not getting hot water then its likely to be the pump or a blockage in the flow through water heater.
3. If above OK then it's a fault with Brew Unit. Follow procedure to remove the brew unit, clean unit and test the air path through both pipes by blowing. Note: When you take out brew unit it not possible to access one of the pipes because its protected by a plastic shield. There is a manual procedure to manipulate the brew unit to expose this pipe so you can blow through it. However the likely cause is not a blockage in these two pipes but the stainless steel filter that the coffee must pass through. You will need an Allen key to remove the bolt holding this in place. Once removed you need to check all holes are free of blockage by inserting a very small wire in each hole. Alternately you can replace this part. If the filter is clogged then you should consider using a different type of coffee as some types coffees cause this problem and others do not.
I hope this helps. regards

SOURCE: My coffee machine dispenses water from the hot

Try running the maintenance on the sysetm:

Tap until "Maintenance" is highlighted, confirm with OK.
^ Select "Rinse the system", confirm with OK.
^ Select "Start", confirm with OK.
When the main menu reappears in the display, the lines have been rinsed. The appliance can now be turned off.

Do you have the manual for your unit? You really need to clean the dispenser unit which requires a little disassembly, and the manual really explains this well. If you don't, I can send it to you if you provide me your email address.

Water won't flow thru to filter or pot. Don't know the exact model but it is a 12 cup self cleaning.


Self-cleaning is wishful thinking. Every three months or so, run a pint of vinegar through it, as if making coffee (no coffee!) then flush with two tanks of water.

Coffee water won't flow


You probably have hard water deposits in the tubing. Run a couple tanks of vinegar through the machine on a brew cycle. Then flush with a couple tanks of water.

Coffee bean light won't go out when full and coffee won't work


Hi coffee friend I have just answered this question. I think
After you have done all the cleaning you have done, you can try this: do check that all knobs correctly set. That the steam spout is closed. that the water tank sitter correctly
Disconnect from power, wait 2-3minutes connect again and hope for the best.

Low extraction flow


if the water pump is working up 9 bars, the coffee group is clean from coffee and scale then your grinding coffee is too fine or more than 8 grams.
