KRUPS „Duothek Plus“
(model #464)
Your new Duothek Plus coffee maker is
a great new addition to your home or
office, and is the perfect choice for
entertaining. The Duothek Plus has the
following features:
●2 x 10 cup dual coffeemaking system
makes one or two pots
simultaneously - perfect for
entertaining!
●Exclusive KRUPS “Deep Brew“
system with special filtering action
for maximum flavor.
●Electronically controlled dual
brewing cycle (left side only) slows
down the brewing process when
preparing less than 3 cups of coffee
to ensure full bodied flavor even in
small quantities.
●Swing out filter holders are
convenient to use and easy to clean.
●“Stop ‘n Serve“feature lets you
serve a cup or two while brewing.
The automatic filter seal allows you
to remove the carafe for 20 seconds
without coffee dripping onto the
warming plate.
●Automatic warming plate keeps
coffee at the perfect drinking
temperature; however, due to the
breakdown of coffee´s aroma, we do
not recommend serving coffee which
has been kept warm more than one
hour.
●Dual water level indicators easily let
you measure how much water is in
each water chamber.
●Hinged water chamber lid will protect
the water chamber from dust and
dirt.
●Krups specially designed heating and
tubing system minimizes calcification
and leaves no residual water in the
system when brewing is finished.
●Hidden cord storage allows you to
set the desired cord length.
Preparing coffee
Before making your first pot of
delicious coffee, we recommend
operating the coffee maker once or
twice with water only, without ground
coffee or a paper filter to remove any
possible dust.
●Be sure that the water container is
empty. Remove literature, etc. if
inserted in the water container.
●The lid of the glass carafe must be
properly positioned during the
brewing process. Position the lid
over the carafe and snap the
rectangular piece onto the handle.
The lid is then locked in place.
●Make sure that the swing away filter
(e) is properly closed during the
brewing process, When closing the
swivel filter you will feel a noticeable
resistance between the swivel filter
and the base. Push in firmly until you
hear the filter “click“into place.
●Caution: If the swivel filter is not
completely closed, the “Stop ‘n
Serve“trigger will not function
properly, which 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 properly closed.
Filling the Water Chamber
Open the hinged lid (see figure 1).
Pour in the desired quantity of water
(see figure 2).
The water level indicator shows you
how much water you are filling into the
container (see figure 3).
The amount of freshly brewed coffee
delivered after the brewing process will
always be slightly less than the amount
put into the water container. 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 you desire.
Replace the carafe on the warming
plate with the glass carafe lid in
position.
Putting in the Ground
Coffee
To open the swing away filter holder,
move the filter handle to the left to
swing the filter out (see figure 4).
Insert a paper filter (we recommend
Krups size 4) with the seam pointing
towards the handle of the filter holder
(see figure 5).
Instead of filter paper you can also use
the Krups goldtone filter (model #053).
(When ordering filter paper or the
goldtone filter from Krups be sure to
indicate that they are for model #464.)
Put ground coffee into the paper filter
(see figure 6). 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
measure to suit your own taste.
Close the swivel filter and make sure
that is completely closed (see figure 7).
You will feel a noticeable resistance
between the swivel filter and the base.
Push in firmly until you hear the filter
“click“into place.
Attention!
Make sure that the filter paper does not
tip over when closing the swivel filter,
or else the water might run between
the filter paper and the filter holder
producing a very weak cup of coffee.
Plug in the coffeemaker and turn the
on/off switch to the “on“position (right
switch for right side, left switch for left
side) (see figure 8).
Replace glass carafe on the warming
plate with the lid securely in position
(see figure 9).

Selecting the fullest flavor
The Krups “Duothek“has a full flavor
selector switch, if you want to make
1-3 cups of coffee, turn this switch to
the appropriate position (see figure 10).
This will extend the brewing cycle so
that the water will seep into the ground
coffee slowly enough to yield brewed
coffee that is rich, aromatic and truly
delicious (works on left side only).
In order to have truly aromatic coffee,
the water must be allowed to seep
through the ground coffee for a certain
minimum of time.
For making 4-12 cups, the full-flavor
switch should be turned to the position
“4-max“.
„Stop’n Serve“Feature
The “Stop’n Serve“feature is KRUPS’
answer to the impatient coffee
drinker’s clamor for “a quick cup of
coffee!“. This device automatically
stops the flow of brewed coffee
through the filter cone of 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 its being
reinserted to allow the serving of one
or two cups of coffee.
The “Stop’n Serve“device closes off
the filter cone so effectively that there
is virtually no coffee-drip onto the
warming plate (one drop, at most!).
Once the carafe is replaced, the
brewing cycle and the flow of the
coffee into the carafe are resumed.
Caution
If the coffee does drip onto the warming
plate after removal of the carafe, it is
usually an indication that the small black
seal in the filter holder is missing or
defective. It is also possible that too
much ground coffee has been placed
into the paper filter. This causes the
water that jets into the filter cone to
overflow between the paper filter and
the sides of the filter cone.
The overflow carries the coffee
grounds with it that interfere with the
snap-shot action of the filter holder,
thus allowing brewed coffee to
continue to drip through.
If this blockage and subsequent
dripping do occur, replace the glass
carafe immediately and allow the full
brewing cycle to run its course. Do not
swing out the swivel filter until the
brewing cycle is completed.
Cleaning
●Always unplug this appliance before
cleaning. Remove the filter holder by
opening the holder and lifting the
filter directly off (see figure 11).
●Clean the filter holder, the carafe and
carafe lid in a solution if hot water
and mild liquid soap. These parts can
also be placed in the upper level of
your dishwasher for safe effective
cleaning.

11
●Never use scouring agents.
●Never immerse the appliance itself
in the water or any other liquid. To
clean, simply wipe off with a soft,
damp cloth.
● Never use a cloth to clean the inside of
the water chamber, as this might leave
fuzzy deposits in the chamber. Just
rinse with cold water, periodically.
Decalcifying
Although your KRUPS coffee maker
has the most advanced water heating
and pumping system, it will
periodically need cleaning with a
decalcifying agent.
●This is due to the calcium (limestone)
found in drinking water.
● In some areas where the water is hard,
you will need to decalcify more fre-
quently than in areas with soft water.
●It will also depend upon how often
you use your coffee maker.
When to decalcify
You will know when such a cleaning is
necessary by an obvious slowdown in
the brewing time of your coffee. This
extended time indicates that there are
calcium deposits in your coffee maker.
We recommend using a decalcifying
agent for cleaning your KRUPS coffee
maker. If used in accordance with the
following instructions, it will prolong
the life of your coffee maker.
Decalcifying agents can be found in de-
partment and gourmet specialty stores,
or by calling KRUPS Consumer Service.
