APPARTAMENTO
7.5 Parameter reset (Factory Reset)
By means of this procedure it is possible to delete all set parameters and restore the original factory setting. This function should be used in those cases where errors or unwanted variations have been introduced, choosing to reset everything and return to the initial conditions.
This procedure is carried out as described below.

1. From Machine OFF, switch the machine ON with the unit lever in the dispensing position (contact closed); the machine does not perform any action but waits for a few seconds for a sequence from the operator.
2. Keep the lever in the dispensing contact position. After a few seconds, if the lever has always remained in the same position, the machine turns on the yellow light (as for normal programming) for 5 seconds until the flashing green light appears.

3. If, within 3 seconds of the green light coming on, the lever is returned to rest, a factory parameter reset (default) is implemented, indicated by the permanence of the steady green light. If, on the other hand, the lever is left in the dispensing position, after the 3-second time limit has elapsed, the green indicator light will remain flashing without performing a parameter reset, waiting for a Poweroff.
4. Switch off the machine and if the reset procedure is not implemented, return the lever to the home position anyway.

8.5 Cleaning the drip tray
1. Remove the grid and the tray and wash with warm soapy water. Rinse and dry. (fig._8.9)
fig_8.9 2. First reassemble the tray, making sure that
it is placed and inserted (with horizontal movement) until it reaches the “stop”, after “hooking” has taken place (a magnetic click at the end of the stroke should be heard – fig._8.10)
CAUTION: If the tray is only left resting and not fully inserted, the water coming out of the group and from the drain flows into the front part of the base and could come out of the machine.

8.6 Descaling

1. ROCKET does not recom-

mend removing limescale from

the espresso machine. Con-

tact an authorised ROCKET

centre for descaling.

2. Many of the chemicals used

i

to descale espresso machines are particularly aggressive. These chemicals can cause in-

ternal corrosion of hard metals

used in the construction of the

machine.

3. Additionally, it is very difficult to

remove all the descaling solu-

tion from the machine once the

procedure is completed.

4. Check the quality of the water you use in

the machine, always using filtered water.

Distilled water may lack the necessary

conductivity required for various elec-

tronic functions needed in the operation

of the machine.

8.7 Boiler water replacement
It is recommended to change the water in the boiler periodically, at least once a month or, in the case of frequent use, every fortnight. Read all the steps described below carefully before performing the operation; if in doubt, contact the ROCKET service centre for clarification and support.
IMPORTANT:
This operation must be carried out with the machine just turned off with hot water and the boiler pressurised (fig._5.4).

9.2 Troubleshooting
The machine does not start Check that the main switch is in the ON
position. Check that the plug is inserted.
No coffee or steam dispensing
Check that water is present in the tank .
Check that the coffee and steam controls have been activated before dispensing . The machine does not heat
Contact the technical assistance
Irregular steam dispensing
Make sure the sprayer holes are clean
Extraction is too slow Check that the filter basket is not too full
(too much coffee).
Check that the grind is not too fine.
Check that the shower foil is not blocked: it may need to be back-flushed or be removed and cleaned
Check the spout of the handle is not blocked. If it is dirty with rancid coffee oil, it will need to be soaked in an espresso head cleaning solution.
Water leaking from the portafilter
Check the head gaskets. If visibly worn, they will need to be replaced.

APPARTAMENTO
Ensure the portafilters are kept in place on the head whenever the machine is not in use, as this will help to protect the seals.
Espresso is too cold Check that the cups are hot enough.
Cups can be heated by pouring hot water into them, and then discarding it, before starting the extraction. Too much water may have been drawn from the unit head. Let the machine rest and limit the amount of water drawn from it between extractions to ensure the machine remains at temperature.
Water underneath the machine
Check that the tray is inserted correctly
Check that the drain tray has been emptied
The machine appears to be off but the switch is in the ON position
Check that the Eco mode function is active by operating the coffee control (see par. 6.4).
Switch the machine off and on again from the main switch (see 1 – fig. 3.2 3.3)
Espresso tastes bitter
Extraction may be too slow. Check that the grinding is not too fine. Correct the grinding and make it coarser.
The machine may be dirty. Backflush again and clean the unit head. Clean the portafilters and filter baskets.

Espresso tastes sour
Extraction may be too fast. Check that the grinding is not too coarse. Correct the grinding and make it finer.
Espresso is watery and thin
Extraction may be too fast. If so, the cream will be pale. Check that the grinding is not too coarse. Correct the grinding and make it finer.
Espresso is bubbly
The water in the machine may be too hot. Let some water flow from the unit head. Perform another extraction.
The coffee may be too fresh.
Low or no pressure from the steam wand
It may be due to excessive use of the unit head. Excessive use of the steam wand. Give the machine time to recover pressure.
The steam wand may be clogged with dry milk. Remove the nozzle and clean it as indicated in point 7.1.
Milk is thin and bubbly
Ensure the milk is diluted gradually. If air is introduced too quickly, large bubbles will form.
Make sure that the steam comes out with the right pressure and that there are no blocked nozzles.
It may be due to using reheated milk. Try again with fresh milk.
