1. COMPONENTS
The appliance is made up of:
1 1.3-L removable water tank
1 flowmeter to proportion the volume of water
1 15-bar pump + 16-bar relief valve
1 motorized hydraulic distributor
1 1300-W thermoblock system with:
- 1 coffee water circuit and 1 steam circuit
- 1 integrated percolation chamber
- 1 NTC for electronic temperature regulation and two 216°C thermal fuses
- 1 system for discharging the ground coffee by means of an ejection ram and scraper
1 hydraulic plunger for closing the percolation head
1 grinder
2 electronic boards for:
o thermoblock temperature regulation
o mesuring the waterflow volume by counting flowmeter pulses.
o 1-cup, 2-cup, hot water (graphic model), steam, cleaning and scale removal cycle
operations
o current function display via indicator light (pictographic models)
o after service information (number of cycles per function, failure code....)
2. OPERATION :
NTC electronic temperature regulation:
Coffee: 108°C (position 1), 113.5°C (position 2), 122°C (position 3)
Steam: 150-140°C
Safety cut-off : 190°C
1-cup cycle:
See cycle description with hydraulic diagram.
2-cup cycle:
2-cycles of 2-half-cups sequencing.
Cleaning cycle: only applied to the coffee circuit.
Succession of cycles pumping 50ml of water / 2-minute pauses.(in cleaning) or 1 min (in rinising)
Scale removal cycle: applied to steam circuit.
Succession of cycles pumping 50ml of water / ~ 45 sec pauses.
Automatic priming function:
Priming is automatic if there is no flow during actuator down phase pumping via steam nozzle.
Machine reset function if a fault occurs then blocking on fault if it is repeated on the next cycle: this
function allows fugitive faults to be ignored.
Corrective rinsing function proposed automatically in event of fault 8 (coffee flow defect through clogging
of coffee grids).
Function for detection of non-ejection of grind cakes with automatic ejection cycle.

removed)
Use an Oetiker clamp reference: 14100083 (cutting pliers not recommended as non parallel
tightenng).
Pinch until the 2 parts of the clamp loop are brought into contact.
3
Grinder :
2
1
Indexing and assembly of the grinder crown to be performed on coffee maker:
1) For Krups versions, set the grinder using the blue marker or failing this the green
marker (or red) of the ring positioned opposite the indexing ball
2) place the drive axis at stop on the “coarse grind” position
3) assemble the crown on the grinder (4 clips) and on the drive axis.
Ensure that wires go through the grommets.
NB: check that the brass spacers are mounted in the grinder screwing holes.
8
Coffee pouring spout:
Add a double wire to break the blocks of coffee coming out of the grinder (application on 19/06/06).
Be careful of
correct assembly
direction of
double wire
Grinder setting:
The grinders are run in and calibrated so no adjustment is needed.
After any intervention on the grinder or the electronics, or after setting of the grinding time, the
thickness of the grind blocks must be checked: 12 to 14 mm.
Test conditions:
rd
- measurement of cake thickness on 3 coffee cycle
- strong espresso function 60 ml
- setting of grind fineness in “coarse” position
- coffee: small beans (max. average length 10.5 mm) that are also dry (important)
If the thickness of the cakes does not comply, you can check the pre-programmed grinding time (must
be 7, 8 or 9 sec) and set this time if necessary:
-
EA8000 / 8005 / 8010 Models:
- Consultation of pre-set grinding time
Read the grinder setting 0, 10, 20, 30 or 40 in the small display on line 22 of the
Product Support mode (see table below).
- Setting grinding time
- Remove the cake tank, slide and tank.
- Press the key “steam” + mains connection
Illumination of 1 of the 5 facade lights (depends on position of the rotary selector
and not programmed setting)
- Use rotary selector to choose illumination of:
- “cake tank” light for 7s of grinding time
- “water tank” light for 8s
- “clean” light for 9s.
- Press the “service” key to validate.
Illumination of “cake tank” light + “water” light flashing
- Disconnect the coffee maker.

Lead
Respect the earthwire routing.
The lead earthwire must not be in contact with moving parts (stainless steel corners behind the
actuator) or hot parts (resistor and lug connectors)
10
Wiring
Grommets are to be respected in order to comply with interference suppression requirements:
generally speaking, wires which ensure power transmission (thermoblock, pump, grinder) are not
routed the same way as low voltage / low current wires.
Wires are arranged in the following order:
1. - 2 green water-level wires + 3 red flowmeter wires
2. – control board connector
3. - 2 blue NTC wires
4. - 2 green draw switch wires
5. - 2 blue-red distributor motor wires + 3 black-yellow-white distributor switch wires
6. - 2 grinder wires
See wiring photos in enclosed document
Make certain of the correct position of the black connecting wire between the
switch of the cylinder
For POWER board
The brown wire
Wires are pushed down in the low position on the board
11
Pump
The loop of the Oetiker clamp must be oriented downwards to guarantee non-contact with the base
Flowmeter :
Respect hydraulic connections:
pump tube on the flowmeter lid
tank tube on the flowmeter casing.
Hoses must not be twisted or bent.
Thermoblock-actuator sub-assembly
Direct the device for closing the clamp on the actuator pipe downwards (risk that this might get in the
way of the ejection scraper).

Tamping head
When screwing, be careful not to offset the tamping head mount

Thermoblock and ejection scraper interface

.
Cylinder rise detection switch:
Make certain there is no voltage on the wires of the cable
Distributor
Replace the 2 pins of the drain receptacle properly in the 2 holes of the base.
Check that all hoses are tightly connected, in particular the easily detachable drain hoses, and that the
clamps are properly clipped onto the high-pressure hoses.
Check that the drain hose is not bent or caught
The ejection rod " Barista " seal
Ensure that re-assembly is made the correct way up (lip facing upwards).
Only grease the ejection rod, and sparingly, with food grade grease
Distributor drain casing
Be careful to centre the spring properly on the bushing at the bottom of the drain body (risk that it
might catch on the notches).
The drain plunger must be mounted in the body of the drain with food grade grease.
Ensure that the drain body is firmly locked down on the distributor (tighten counterclockwise).
13
Electronic boards
Connectors on electronic boards: check that connectors are well secured by the clips.
Check the coffee volume selector button for correct indexation (1/2 turn possible error).
Check ground coffee cake thickness after any work on electronics or the grinder.

Make certain of the correct position of the tank connection seal under the body.

8. SERVICING AFTER LOGGING UP OF GROUND COFFE :
Remove the cleaning inlet and the drawer.
Scrape and suck up the ground coffee in and around the thermoblock tank using a vacuum cleaner
with a small end piece (flexible hose with ~10 ext. diameter).
Carry out a cleaning cycle:
If the ejection ram works properly in the tank OK
If it sticks, activate manually with a rod inserted through the base:
Check that the drawer switch works properly: any ground coffee in the drawer slide channels could
affect the control. If this is the case, remove the technical mount to clean the slide channels.
Renew a cleaning cycle.
Determine the reason why clogging-up occurred (see troubleshooting diagnosis table):
grinder not compliant (quantity of ground coffee)
electronics setting not compliant with the grinder
ejection ram stuck in high position
cake tray replaced partially full
9. CLEANING AND SCALE REMOVAL CYCLES :
The cleaning light comes on after 350 coffees (or espressos).
The scale removal light comes on after:

12. AFTER-SALES (A-S) MODE OPERATION
1st-level A-S mode
This mode makes it possible to access information on the rate of use of different coffee-maker functions.
Pictographic model
Access to A-S 1 via combination of the following keys: Service + Strong Coffee key+ Mains
Connection.
The Strong Coffee key enables functions to scroll and the Coffee key to return. No signalling.
Access counter values of the different functions via the Steam key and return via the same Steam
key. Signalling via the Calc light.
