Instructions vary a bit according to machine, but a safe bet is to use a mix of 1/3 white vinegar to 2/3 water. If you are uncertain, you can always type the name or model number for the coffeemaker into a search engine along with the words "owner's manual" or "user guide" or words to that effect. The other option is to visit the manufacturer website. There should be a search box or a "support" section of the website where you can look up your coffeemaker and view a PDF of the owner's guide (the PDF will either download to your desktop or open in your web browser).
In general:
1) Put the filter basket in place and set the machine up as if you were going to brew coffee. 2) If there is a charcoal water purification filter in the machine, take it out.* 3) Run the aforementioned vinegar solution through as if you were brewing coffee. (Just hit the brew button after adding at least 6 carafe cups of diluted white vinegar.) 4) Wait about 10-15 minutes to let the machine cool down and then "brew" the vinegar solution through again if it has been a long while and the deposits are particularly severe. (Note: Some owner's manual will have you pour the vinegar that is in your carafe back into the water tank and run it again, and others will call for you to discard the first batch and brew through a fresh solution.) 5) Follow the same instructions as written above but this time with a full carafe of fresh water (no vinegar). Repeat 2-3 times to rinse out the vinegar odor/taste. 6) To clean your carafe use hot water, baking soda and vinegar. Place the carafe in the sink, fill with hot water, pour in some baking soda and add in a 1/4 cup or so of white vinegar. The foaming action will help release stains and stale coffee odors. If the stains are particularly severe, dissolve a tablespoon or so of liquid dishwasher detergent in extremely hot water — be careful! — and pour it into the carafe. Let it soak for an hour or overnight and rinse with hot water about 4-6 times to make sure the solution is entirely rinsed out.
* Tip: If your coffeemaker has a water purification filter, do not reinstall after cleaning your machine if you can't recall the last time you replaced it. A worn out charcoal filter cannot be cleaned, may slow down the brew speed or make the coffee taste "off". The only option is to remove or replace it with a fresh water filter. This is only applicable if your coffeemaker came with a charcoal water filter. If present, you will typically find it inside the water tank inside a plastic holder of some sort.
Good luck!

I cleaned my Jura Capresso with a tablet, but the message "Clean Machine/Ready" won't switch back to "Ready". Any suggestions?

Fortunately the problem you describe is not model specific. All Jura machines in the series C, E, F, J, S & Z models have the same problem. The Jura recommended maintenance is insufficient or erroneous. Here is how it occurs:
1- When new machine is set up, the instructions advice the owner to set up OK for use of Filter cartridges. This set helps only to display reminders for replacing the filter.
2- The initial set up instruction also advises that with regular use of Filter, descaling the machine will not be needed. That is really not accurate. Consequently, the reminders for descaling are delayed for over one year or more. This causes serious consequence with accumulation of Calcium deposits in the entire hydraulic and coffee system.
3- Use of Filters alone does not prevent Calcium deposits. Cleaning tables recommended & sold by Jura do not remove Calcium deposits in the coffee/water passages. The automatic descaling method recommended by Jura leaves the coffee side of the machine unclean. The error message in your machine is due to Calcium deposits in the Brew group, coffee outlet & the faucet dispensing coffee in the cup. I suggest all Jura machine owners should manually descale machine. Manually descaling includes use of 6 to 10 rinse cycles with descaling solution in the water tank. The error message "Clean Machine" is accurate. This error message is pointing to descale the Brew group, coffee outlet tube and coffee dispensing faucet by using rinse cycles.

After the rinse cycles are complete, refill Descaling solution in the water tank & continue descaling the rest of the machine by using hot water dispensing function, ½ cup at a time until the tank is empty. Finally, give a final flushing of machine to flush out remaining descaling solution inside the machine.

Just a guess here but if you are not using soft water you may have a hard water scale coating on the sensor. The sensor is preventing the heating element from powering up because it thinks there is no water. Try filling the machine with vinegar for several hours (no more than overnight) This will dissolve hard water deposits and hopefully clear the sensor. (the sensor should be a simple continuity contact. If you can look inside and see a metal button and it is fouled clean it off.)

Hose does not dispense cleaning solution, and the cleaner solution will immediately go down to the dirty water tank. It can suction, though. Any tips?

sounds to me as if you have calcium deposits from hard water.

Take your cleaner solution reservoir and fill it with Vinegar and Hot water. Place your machine in a dry bathtub and run it until the tank is empty. Do this a couple times. When it works properly run some clear water through.

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.

Jura Impressa X90 doesn't give water or coffee. Keeps saying: fill system

Hello, make sure the magnet in the water tank moves freely, sometimes it gets stuck with deposits, its a small black rectangle near the base. if its not free, you need to put some descaling solution it the tank to clear it.

My Vick's Warm Mist V74A was absolutely lovely when I purchased it (May of June of 2010). However, I CAN ADMIT (because I'm sure majority of people are not) that I have not cleaned it since or read my...

The simplest and easiest way to clean the interior workings of the unit is to fill the tank with a 50/50 solution of White Vinegar and Bottled Distilled Water. Run the unit for an hour. Turn it OFF for 30 minutes and the run it again, until the tank is almost empty and turn the unit OFF. Empty the remaining solution and refill the tank with Bottled Distilled Water. Turn the unit ON and operate it for at least 45 minutes to an hour. This will flush out all of the remaining solution.

What you saw before before cleaning the unit, was a build up of mineral deposits and scale from the tap water that you used. In the future, I would highly recommend that you use Bottle Distilled Water, rather than tap water. That way, you won't have to flush the unit as often and you'll be using water that is mineral free.

Hope this helps you solve the scale and mineral deposit problem. Please don't forget the rate my response to you. Thanks!

Steam doesn't come out anymore when I pull the trigger. I think the water in the tank is getting hot, but when I pull the trigger, only a little water comes out. No steam

Try putting some white vinegar in the tank to dissolve any hard water deposits. You should use only distilled water in this machine. Don't try to clean anything with the vinegar in it, but take it outside to run the vinegar through.

Cleaning instructions

I was looking for instructions as well, because I thought I had lost the manual. But then my wife found it. According to pages 8-9 (I scanned the pages as well and posted it here):

Always be sure that the appliance is unplugged and switched OFF before cleaning or attempting to store the item. NEVER PLUG OR UNPLUG UNIT WITH WET HANDS.

DO NOT leave water in water tank or water basin when unit is not in use as it may result in the build up of mineral deposits and bacteria that can inhibit the output efficiency of the humidifier.
PLEASE NOTE that if the water remains in the water tank for more than a day or two, bacterial growth is possible.

ALWAYS use fresh cool water when using unit.

NOTE: When removing water tank, water may accumulate under vapor lid and on the bottom of the water tank. It is recommended to have a dry cloth ready to dry wet surfaces.

1. Fill water tank with 1 teaspoon of household bleach in 1 gallon of water. Let stand twenty minutes, shaking vigorously with two hands every few minutes, drain and rinse with clean water until the bleach smell is gone. Dry with a clean cloth or paper towel.
2. Wipe the water basin with a soft cloth dampened in the bleach and water solution. Rinse the water basin with cool water to remove any bleach smell. DO NOT IMMERSE WATER BASIN IN WATER.
3. Wipe all exteriors surfaces of the base with a soft, dry cloth. Do not immerse the base in water or use water to clean the base. An electric shock may result or the humidifier may be damaged.

Before any cleaning operation, switch the humidifier off and unplug it.

1. Always unplug the unit before cleaning.
2. The humidifier must be drained and cleaned before storing.
3. Once unplugged the exterior of the unit may be cleaned by wiping with a soft dry cloth. Caution: The ON/OFF switch must be throughly dry before unit is again plugged into power source.
4. There may be some lime deposits in the nebulizer, particular in areas with hard water. Overcome this drawback by cleaning the nebulizer with water and vinegar on a soft cloth regularly, as follows:
A. Dampen a cloth with vinegar and wipe the nebulizer gently, until the lime deposits disappear completely.
B. Rub down gently with a dry cloth and remove remains of humidity.
C. Do not rub the nebulizer with solid objects.
D. Do not clean with chemical products
5. When cleaning the water basin do not place the nebulizer directly under the water tap.
6. Never immerse the unit in water or let water enter the fan vent (see figure 3) or any other openings.
7. It is normal for water to be in the water basin. However water must not get inside the central body. If this should happen, take the humidifier to an authorized service center before using it again.
8. Clean the inside of the water tank at least once a week, as follows:
A. Fill the tank with clean water adding a few drops of bleach. Close the tank completely with its cap and shake by holding the tank with both hands. Do not hold by handle while shaking the tank.
B. Rinse thoroughly.
