REPAIR INSTRUCTIONS

Working principle of the appliance

To understand the appliance better, hereby a short technical description of the working principle.

When the appliance has been plugged on the mains, the appliance starts with a self diagnose.

First items that will be checked are:

- Temperature sensor(s), state of micro switches.

Second:

- If no malfunction detected the Brewing unit will be moved downwards and after actuating the micro switch

brewing_unit_down_position M2, the brewing unit will be brought to the mid position (in this position it is possible to remove
the Brewing unit for cleaning purposes).

- During this movement the Hall sensor will count the needed cycles to go to the right position.

- After this has been accomplished the appliance will shut it selves off.

If there is a problem detected in above actions the Display will show a “GENERIC ALARM” message.

Note:
If the appliance is still in factory mode, the appliance will not shut it selves off.
First the available languages will be displayed and after the selection of the language the appliance starts the water fi ll routine.
Follow the steps indicated in the displayed after the process the appliance will shut it selves off.

Switching the appliance on:

When the appliance has been switched on the brewing unit will fi rst be brought to the Coffee fi lling position.

Also the 2 heaters (steam and Coffee heater) will be powered and are heating up. (see also message in the display) (heating up….)

When the right temperature (measured by the NTC(s)) has been reached, the Brewing unit will be brought to the brewing (top)
position until the brewing_unit_up_position M1 micro switch is activated.

Then water will be pumped through the brewing unit (see also message in the display) to clean the Coffee system (Brewing unit &
brewing head).

After this routine the Brewing unit will be sent to the down position (by a mechanical mechanism the Coffee grounds) will be
wiped off.

The Brewing unit will be sent to the Coffee fi lling position again and the appliance will show a message on the display that the
machine is READY to USE.

HD5730/10

Brewing cycle Coffee:

When the user selects one of the Coffee buttons (small- , medium- or large cup of Coffee) depending on status of the appliance the
Brewing unit will be sent downwards fi rst and then go to the grinder fi ll position otherwise the fi rst action will be that the beans will
be grinded into Coffee powder. The Coffee powder falls in the Brewing unit.

When the grinder stops grinding, the Brewing unit will be moved up to the brewing position.

The pump starts to pump a small amount of water into the brewing unit (pre-brewing), the Coffee bed will slightly shrink and
therefore the Brewing unit will be sent up to the brewing position again. (few millimetres)

After 1 – 2 seconds the pump continues to pump the water through the brewing unit and Coffee will leave the Brewing unit via the
Coffee spout into the cup.

When the right quantity of water has been reached (measured by the fl ow counter), the pump stops.

The Brewing unit will be sent to the down position.

In the down position the Coffee residue will be wiped off. The coffee will fall in the removable waste bin container.

After this the Brewing unit will be sent to the Coffee fi ll position again.

The Coffee brewing cycle has been performed.

• Hardness setting 4 • Hardness setting 3 • Hardness setting 1

• Performed cycles decalcifying 3. • Performed cycles decalcifying 3. • Performed cycles decalcifying 3.

Calculation: Calculation: Calculation:

120/45 = 2.66 round down to => 2. 700/80 = 8.75 round down to => 8 1000/250 = 4
2 – 3 = –1 < 3 8 – 3 = 5 > 3 4 – 3 = 1 < 3
Descaled routines performed ok! Descaled routines performed Not OK! Descaled routines performed ok!

If the number of decalcifying routines performed deviates more than 3 times of the formula outcome the machine has not been
properly decalcifi ed.

Conclusion:

The outcome of the formulas must be more or less equal to the number of decalcifying routines carried out by the consumer.

Example1 and Example3 are in line with the recommanded number of descal routines performed as requested by the appliance.

Example2 there it is clear that the appliance has not been descaled according the instructions given by the appliance.

The outcome of the formula deviates more than 3 times of the requested number of descaling of the appliance.
