OPERATING
OPERATING
Machine status
After switching on, an automatic self-test is performed to check if the
- capsule holder is inserted (with reed-switch)
- NTC is connected,
- NTC is short circuited,
- the thermoblock reaches the working temperature within 30 seconds.
Operating modes and detected failures are indicated by LED signals of the power button
as listed in the following table:
Operating modes Power button LED signals
Economy mode / Off —
Heating up / self-test red, blinking, approx. 30 sec
Ready green, steady
After beverage preparation (cool-
down time) red, blinking, approx. 5 sec
Descaling ready and during des-
caling cycle green, slow blinking
Error mode red, rapid blinking

OPERATING
Preparation, first use
The new machine has to be rinsed properly before first use according to the following
sequence:
A timer or stop
watch is helpful to
observe the rinsing
times.
The machine will
not work without a
capsule holder inserted.
Do not insert a
capsule yet.
The pre-heating
time is approx.
30 sec.
1. Rinse water tank at first. Then fill
water tank with fresh, potable water.
2. Check that capsule holder is empty
(no capsule) for the following rinsing
precedure.
3. Insert capsule holder and close
locking lever.
4. Place a jug with enough capactiy
under outlet.
5. Make sure that selection lever is in
central position.
6. Connect mains plug.
7. Switch machine ON.
8. Wait till power button lights up green.
9. Set selection lever at position z
(cold water). Let water run through
for approx. 80 sec.
80 sec

OPERATING
The drip tray is
height-adjustable in
3 levels.
10. Set selection lever at position z
(hot water). Let water run through
for approx. 80 sec.
11. Set selection lever at middle position
to stop rinsing.
12. Remove and empty jug.
13. Refill and insert water tank. 14. Remove protective foil from drip grid.
15. Insert drip tray.
The machine is now ready for use.
80 sec

OPERATING
Preparing a beverage
Choose an
appropriate cup
size for beverage.
The locking lever
can only be
actuated if the selection
lever is in the middle
position.
Users allergic to
dairy products:
clean capsule holder
under running water
before use.
For capsule prod-
uct range see user
manual or:
www.dolce-gusto.com
For filling amounts
see product package
of capsule or user manual.
The flow speed
depends on the
used capsule.
T
he machine does
not turn off auto-
matically.
Danger of hot
water and product
splashes - capsule can
burst.
Do not open locking
handle prematurely.
1. Check if water tank is filled.
2. Check if machine is ON and ready.
3. Re-adjust drip tray if necessary.
4. Place a cup under outlet.
5. Open locking lever and pull out
capsule holder.
6. Insert a capsule in capsule holder.
7. Insert capsule holder in machine and
close locking lever.
8. Set selection lever at position hot
water zor cold water z, depending
on beverage.
9. Push selection lever back to middle
position after specified filling amount
is in cup.

This chapter contains special security and assembling notes.
Tools and repair accessories
With the following tools, all described repair work can be done:
• Torx screwdriver for security screws Pin-TX 10
• Phillips screwdriver no. 1 and 2
• Screwdriver with 4 mm width
• Pointed flat pliers
• Flat nose pliers
• Fork wrench no. 8
• Fork wrench no. 12
• Cutter (stanley knife)
• Heat conducting paste
Repair work without disassembling the machine
Without disassembling the machine, you can replace or repair the following parts:
• water tank assembly and cap
• capsule holder
• injector plate
• drip tray and drip grid
• capsule bin
Non-observance
can lead to injuries
and damages!
A pin-torx screw
head looks like this:

REPAIR
Removing injector plate, de-blocking of injector
Solid residues in the water circuit can block the injector completely. An example is the
development of calcium particles if the machine is not descaled periodically. Therefore
this error appears during descaling frequently.
1. Remove capsule holder and close locking handle.
2. Release latch by pressing a suitable pin (dia. 1.8 mm max. e.g. a paper clip)
through hole and remove injector plate (C) by pulling it down.
3. Examine upper side of injector plate.
4. Clean interior space of sealing ring (E) with a toothpick etc.
Danger of injury -
sharp pointed
injector (D)!
The extraction
head is adjusted to a
specific injector plate.
Therefore do not
exchange the injector
plate or mix up different
injector plates.
C
D
If upper side of
injector plate is wet
and badly soiled, the seal
(E) is defect. In that case
replace complete extrac-
tion head (see page 34).
