Before First Use

We recommend that you get familiar with all the parts of your KRUPS espresso machine before using it for the first time. Insert the filter basket into the filter holder, fit the filter holder into the filter rings, remove and replace the boiler cap. Check the different positions of the switch. To remove any residuals of production which may rest in the appliance, we recommend operating the espresso maker (as described in “Making Espresso“ section) once or twice with water only, without ground espresso coffee. Wash all loose parts in warm soapy water, rinse thoroughly, and dry. Read all instructions, cautions, notes, and attentions before actually using the machine.

CAUTION: PRESSURE

Never open boiler cap (a) or remove filter holder (e) while your “Il Caffè Duomo“ is turned “on“ or as long as there is pressure in the boiler container. Never move or remove the filter holder while the “Il Caffè Duomo“ is in operation and under pressure. Please follow the instructions listed below to see if the machine is still under pressure. Follow these safety precautions while your machine is in use and ten to fifteen minutes after last use.

Turn the “on/off“ switch to the “off“ position and unplug the appliance.
Carefully open the steam release knob (b) by slowly turning it counterclockwise. If steam comes out of the nozzle, then the boiler chamber is still under pressure. Close the steam knob and proceed with the instructions listed below.
Take a pitcher filled with cold water and hold it underneath the steam nozzle with the nozzle inserted into the pitcher. Then open the steam release knob (b) by turning it counterclockwise. Leave the steam release knob open until no more steam comes out of the nozzle. When finished, turn the steam knob clockwise to close.
Now you can remove the boiler cap and the filter holder.

Genuine Espresso

Espresso is a far richer and stronger brew than regular coffee. It should be deep, dark, and delicious. Most people find that they enjoy it in small quantities because of its richness, and for that reason, espresso is usually served in small (2-2 1/2 oz) demitasse cups. Your “Il Caffè Duomo”, properly used, will always produce espresso that is deep, dark, and delicious. Just follow the instructions and use fresh, well-roasted, pre-ground espresso or espresso beans you grind yourself. Preparing espresso or cappuccino is different from brewing regular drip coffee. One main difference is that the water will come to a boil and will then be forced through the ground coffee. This means that an espresso machine works under pressure and needs special attention.

CAUTION - HOT: Do not touch the boiler cap (a) during operation. Before removing the boiler cap, turn off the machine, let it cool down for at least 2 or 3 minutes. Relieve pressure. See CAUTION - PRESSURE.

Making Espresso

Place your “Il Caffè Duomo” near an electrical outlet and release enough cord so that you can plug in the machine (see figure 1).
Place the filter basket (i) into the filter holder (e) (see figure 2).
Fill with ground espresso. The filter basket is marked on the inside for 2 and 4 cups. Pack the coffee lightly and clear any excess coffee from the rim of the filter holder. This will assure proper fit to the brewing head (see figure 3).

ATTENTION: Do not pack coffee too tightly. Do not fill more coffee than indicated by the four-cup marking into the filter basket. This might cause clogging or overflow.

To insert the filter holder, line up the arrow located on the thumb guard of the filter holder with the arrow on the left side of the machine. Raise the filter holder up into the brewing head and turn the filter holder firmly to the right, until it can go no further. The arrow on the filter holder should be as far right in the lock-range as possible. If the arrow is not at least in the middle of the lock-range, do not operate the machine. Rather, remove the filter holder and reinsert it as described above until the arrow is within the lock-range (see figure 4). By following this procedure, this will prevent the filter holder from being dislodged as pressure builds up during the brewing process.
Open the hinged lid and unscrew the boiler cap by turning it counterclockwise (see figure 5 + 6).
Fill the boiler container with cold water using the markings indicated on the glass carafe (see figure 7).

CAUTION: Never fill the boiler while your “Il Caffè Duomo” is switched on. Never fill more than 20 oz of water into the boiler. The glass carafe has markings for 2 and 4 cups:

2 cups of water = 2 cups of espresso
3 cups of water = 2 cups of espresso, plus steam for frothing milk for cappuccino
4 cups of water = 4 cups of espresso

Maximum capacity to the bottom of the metal band around the glass carafe = 4 cups of espresso, plus steam for frothing milk for cappuccino.

CAUTION: Never fill the carafe above the bottom of the metal band!

NOTE: It is very important to fill only the amount of water you need into the boiler. Your “Il Caffè Duomo“ will always need to process all the water until the boiler is empty. Close the boiler cap securely by turning it clockwise (see figure 8). Place the carafe lid on the carafe so that the lid opening points towards the pouring spout of the carafe (see figure 9). 8. Place the carafe under the filter holder (see figure 10).

ATTENTION: Make sure the overflow grid is in place.

Should you choose to make espresso directly into two cups, clip the two cup adapter onto the filter holder and make sure that the cups are placed correctly underneath the spouts (see figure 11 + 12).
Turn the espresso “on/off“ switch (h) “on“ (see figure 13). It will take approximately 2 minutes for the water to be heated. The water will then be forced through the ground coffee into the glass carafe or cups.
Wait until all the water in the boiler has been used. Switch off the machine.
Do not unscrew the boiler cap while the machine is in operation. Wait until the brewing cycle is completed and all water and steam have been used (See CAUTION - PRESSURE).

CAUTION: Use caution when removing the filter holder, as the metal parts may still be hot. To remove the filter holder, turn the filter to the left, past the ”lock” markings, until the holder dislodges from the machine.

Cappuccino

Cappuccino reportedly takes its name from the chocolate hues of the robes worn by the Capuchin monks who favored this delicious dessert coffee. Cappuccino is traditionally made up of 1/3 espresso, 1/3 steamed milk, and 1/3 froth and can be tailored to one’s own taste with cinnamon, sugar, chocolate flakes, or even liquor. Its versatility makes cappuccino a worldwide gourmet choice.

Making Cappuccino

If the “Perfect Froth“ is not attached, attach it now (see figure 14).
Pour 4 to 6 oz of fresh, cold milk into a small pitcher. The pitcher should fit underneath the steam nozzle. We recommend using 2 % or skim for a stiff, dense froth. Use regular whole milk if you prefer a creamy froth.
Follow the directions from step 1 to 12 in section “Making Espresso“.
As soon as the first few drops of coffee are forced through the filter holder you can start frothing the milk. Place the tip of the steam nozzle halfway into the pitcher of milk.
- a) Turn the steam release knob counterclockwise to release steam (see figure 15).
- b) Keep the pitcher slightly tilted so that you can always see the position of the nozzle as you froth the milk. In just a few seconds, your milk will begin to froth. As the froth rises, keep lowering the pitcher so that the tip of the steam nozzle is always just slightly beneath the surface of the rising froth.

NOTE: Do not bring milk to a boil (this will happen if large bubbles start to form on the surface of the milk).

c) When you have finished frothing milk, close the steam release knob by turning it clockwise while the nozzle is still immersed in the milk. This will avoid splattering of the hot milk and froth.
d) If you prefer “stiff“ froth, let the frothed milk stand for a minute.

ATTENTION: Clogged up steam nozzle Milk residuals will build up in the tip of the steam nozzle after frothing milk. It is very important that you wipe the steam nozzle with a damp cloth after each use. This will help prevent the steam nozzle from clogging and will ensure perfect frothing results. However, should the steam nozzle become clogged, proceed as follows: Let the steam nozzle cool down. Unscrew the tip and clean under warm water. To unscrew the tip, use the opening in the measuring spoon. Make sure that the inside of the tip of the steam nozzle is free, so that the steam can pass freely to froth milk again. Replace the tip of the nozzle and screw on tightly (see figure 16).

Steaming without making Espresso (Steam plug)

CAUTION: Make sure your “Il Caffè Duomo“ is cool and all pressure has been released (see CAUTION - PRESSURE).

Insert the steam build-up plug into the filter holder (see figure 17).
Fill the boiler container with cold water.
CAUTION: For steam only, do not fill the glass carafe above the 2-cup marking. This amount will always provide enough steam for frothing.
Have your pitcher with milk ready to heat.
Place the glass carafe, with lid, under the filter holder and turn the machine “on“ (see figure 13).
Open the steam release knob immediately after turning the machine on. Stand by with your frothing pitcher.

CAUTION: Do not leave the machine unattended at this time. It will take approximately 30 to 60 seconds after turning the machine on for the steam to come out of the steam nozzle. Proceed with steps 4.a) and 4.b) in the section “Making Cappuccino“. 6. When all steam is released, close the steam release knob and turn off the machine.

CAUTION: If you do not need all the water for steaming, proceed as follows: a) turn off the machine, b) release the remaining steam pressure into another container. Do not close the steam release knob before all steam is released or the machine has been turned “off“! (see section CAUTION - PRESSURE).

ATTENTION: The top closure of the “Perfect Froth“ attachment (see figure 18, part A) has a very fine hole which draws air into the milk. If this tiny hole gets clogged, “Perfect Froth“ will not work properly. Therefore, never immerse the top closure in milk or froth.

Setup Guide

The process of setting up the Krups Il Caffe Duomo Coffee Maker 985 is straightforward. Prioritize reading the user manual thoroughly prior to operating the machine. Begin by filling the water reservoir with new, chilled water. Next, place your preferred coffee grounds into the filter basket and customize the coffee's strength and temperature settings according to your preferences. To prepare a cappuccino or latte, simply fill the milk frother with milk and choose the preferred frothing option. Ultimately, activate the device and patiently await its thermal activation. After the coffee is prepared, choose your preferred coffee setting and savor your amazing cup of coffee!

Cleaning

Before cleaning, turn “off” the machine, unplug it, and allow it to cool down. The filter holder, filter basket, carafe, carafe lid, and overflow grid can be put in the dishwasher’s upper rack, away from the heating/drying element. The machine can be wiped clean by using a damp cloth. Never immerse the body of your “Il Caffè Duomo” in water or any other liquid. Clean the brewing head with a damp cloth and remove ground coffee. If there is water left in the boiler chamber, let the machine cool down, remove all loose parts and empty through the top opening by turning upside down.

Cleaning the Steam Nozzle

Clean the steam nozzle each time after you have immersed it in the milk, otherwise the inside of the nozzle becomes clogged and the milk deposits on the outside harden and become difficult to remove.

If clogging does occur, unscrew the tip of the steam nozzle (see figure 16).

Remove all milk particles using a sewing needle and rinse under the faucet. Replace the nozzle tip making sure to screw it on tightly. Wipe off the outside of the nozzle with a wet cloth. Hold the wet cloth very close to the tip of the nozzle and open the steam valve. Let the steam escape into the wet cloth for one or two seconds, then close the valve. Any milk residue will then be flushed out.

Cleaning the “Perfect Froth“ Attachment

For a thorough cleaning of the “Perfect Froth” attachment, remove part C (see figure 18). All parts should be rinsed in warm water. If the small suction opening in part A is clogged up, it can be opened with a fine needle.

Cleaning the Drip Tray

The overflow grid can be cleaned by removing the grid (see figure 19).

CAUTION: Do not try to open or disassemble the main body of the machine.

Decalcifying of the Espresso Machine

The espresso machine must be decalcified regularly. The frequency depends on the hardness of your water and how often you use the espresso machine. Before descaling, the brewing sieve on the brewing head must first be screwed off.

Remove all lime and coffee residues from the brewing sieve and the brewing head.
Pull off the “Perfect Froth“ attachment. For ecological and health reasons, we recommend the exclusive use of biological materials such as citric acid, which can be obtained from KRUPS Consumer Service Department or drugstores.
Dissolve 2 tablespoonfuls of citric acid in 10 fluid ounces of lukewarm water and pour it into the boiler container. Put one receptacle under the brewing head and another under the steam nozzle. (Note: Do not use the filter holder during decalcification)
Open the steam valve and turn on the appliance. Allow the descaling solution to run out of the espresso outlet and the steam nozzle.
After each brewing cycle, switch off the appliance and allow the appliance to cool down.
Repeat this operation once again. Following this, allow 2 boiler containerfuls of clear water to run through the system. Switch off the appliance. Allow the appliance to cool down. Insert the brewing sieve into the brewing head again and push the “Perfect Froth“ onto the steam nozzle.

Preparing Coffee

Before making your first pot of delicious coffee, we recommend rinsing the coffee maker by running one or two cycles with water only, without ground coffee in the filter basket. This will remove any possible dust which may have settled during shipping. Be sure that the water chamber is empty. Remove any literature, etc. if found in the water chamber.

The lid of the glass carafe must be properly positioned during the brewing process. The front hooks have to be inside the carafe and the rectangular part of the lid to be pushed down so that it engages with the handle of the glass carafe.
To release the lid push the rectangular part of the lid upwards.
Make sure that the swivel filter is closed properly during the brewing process. Push in firmly until the handle touches the side of the coffee maker and filter “clicks“ into place.
- Caution: If the swivel filter is not closed in properly the “Stop ‘N Serve” can not function. This may cause hot water or hot coffee to overflow.
The “Stop ‘N Serve” mechanism is opened as long as the glass carafe is inserted into the machine and sits properly on the warming plate and the swivel filter is closed properly. When brewing coffee make sure the glass carafe is in place (see Stop ‘N Serve section).

Putting in the Ground Coffee

Swing out the swivel filter (see figure 20) and insert a paper filter. We recommend using KRUPS size 2. When inserting a paper filter make sure the seam is pointing towards the base of the filter holder (see figure 21).
Use your hands to conform the filter to the contours of the filter holder. This will enable you to achieve better results.
Put ground coffee into the filter holder (see figure 22). We suggest using one level KRUPS measuring spoon of ground coffee for each cup of robust brewed coffee. After using your KRUPS coffee maker several times, you can adjust the quantity to suit your own taste. We do not recommend using coffee that is ground to a powder-like consistency, as this will prevent water from passing through the coffee.
Close the swivel filter and make sure that it is completely closed (see figure 23).

ATTENTION: Make sure that the filter paper does not fold over when closing the swivel filter, otherwise the water might run between the filter paper and the filter holder producing a very weak cup of coffee.

Filling the Water Chamber

Open the hinged water chamber lid (see figure 24). Pour in the desired quantity of water (see figure 25). The amount of freshly brewed coffee delivered after the brewing process will always be slightly less than the amount put into the water chamber. This is due to the minimal absorption of the water by the ground coffee. Therefore, put in a little more water to begin with so that you will have the number of cups that you desire.
Place the glass carafe with lid in position on the warming plate.
Turn “on” your “Il Caffè Duomo” using the coffee “on/off” button (m). The indicator light will illuminate indicating that the brewing process has begun (see figure 26).
As long as the red indicator light is illuminated the coffee will be kept warm.

Stop’N Serve Feature

The Stop ‘N Serve feature is KRUPS’ answer to the impatient coffee drinker’s clamour for a quick cup of coffee! This device automatically stops the flow of brewed coffee through the filter cone if the glass carafe is removed from the warming plate during the brewing cycle. You have about 20 seconds between the removal of the carafe and it being reinserted back onto the warming plate. The Stop ‘N Serve device closes off the filter cone so effectively that there is virtually no coffee dripping onto the warming plate. Once the carafe is replaced, the brewing process and the flow of coffee into the carafe will resume.

CAUTION

Should significant amounts of coffee drip onto the warming plate after the removal of the carafe, it is usually an indication that the seal in the filter holder is missing or defective, in this case call the KRUPS Consumer Service Department at 1-800-526-5377 and they can assist you. It is also possible that too much ground coffee has been placed in the filter paper. This causes the water that jets into the filter cone to overflow between the filter and the sides of the filter cone. If this blockage and subsequent dripping does occur, put the glass carafe immediately back onto the warming plate, and allow the full brewing cycle to run its course. Do not swing out the swivel filter until the brewing process is completed.

Always unplug this appliance before cleaning. Clean the filter basket, carafe, and lid in a solution of warm water and mild liquid soap. These parts can also be placed in the upper level of your dishwasher away from the heating and drying element for safe effective cleaning.

Never use scouring agents.
Never immerse the appliance itself in water. To clean, simply wipe off with a soft, damp cloth.
Never use a cloth to clean inside of the water chamber, as this might leave fuzzy deposits in the chamber. Just rinse with cold water periodically.

Decalcifying of the Coffeemaker

The coffeemaker must be decalcified regularly. The frequency depends on the hardness of your water and how often you use the coffeemaker. Recognizable indications that descaling is necessary are: increased noise during boiling, longer preparation time. If usage is frequent, descaling should be carried out as follows:

with soft water once a year
with medium hard water every quarter year
with hard water once a month

In doubt regarding the water hardness in your area, you may call your local water department. For ecological and health reasons, we recommend the exclusive use of biological materials such as citric acid, which can be obtained from KRUPS Consumer Service Department or drugstores. Dissolve 2 tablespoonfuls of citric acid in 1/2 quart water and pour into the water container. Run this through 2 or 3 times as if making coffee, but using no ground coffee. The hot descaling solution must be allowed to cool down before being poured into the water container. Finally, do the same twice using clear water.
