Note: the machine has an electronic level valve so it automatically feeds in water to the boiler as needed to restore the level.
N.B.: the machine safety system shuts down the machine after the pump has been running steadily for approximately 2 minutes (this prevents the pump from overheating). In this case, turn off the
17
machine by pressing the main switch and then turn it on again.
While the unit is operating, the ON light (2) and the heating light (7) are both lit.
3) Wait until the heating light (7) goes off, indicating that the water has reached the desired temperature.
4) Note: if the water light (6) goes on, it means that the water reservoir (12) is empty or nearly empty.
5) Note: remember that to obtain a good drink it is best to use the cup warming shelf (14) to keep the cups warm.
6) At this point the machine has been set up and is ready to make coffee or produce steam.
6) Rotating the filter holder (b4) insert it into the attachment (9) until it is tight.
7) Position the cup under the spout.
8) Press the coffee dispensing button (4), light 5 goes on and coffee starts filling the cup.
9) Once the desired level has been reached, press button 4 to stop the flow and light 5 goes off.
10)Note: if the unit is to be used frequently the coffee can be left in the filter until the next serving.
If it is not used frequently, empty out the filter and clean it.
11)At this point you have finished preparing of a single cup of coffee.
2) Fill the coffee measure (b6) flush.
3) Place the coffee into the single-cup filter (b4).
4) Using the press (b5), compact the coffee uniformly.
5) Clean the edge of the filter.

2) Fill the coffee measure (b6) flush.
3) Place the coffee into the two-cup filter
(b3).
4) Fill the coffee measure (b6) a second time.
5) Place the second dose of coffee into the two-cup filter (b3).
6) Using the press (b5), compact the coffee uniformly.
7) Clean the edge of the filter.
8) Rotating the filter holder, insert it into the attachment (9) until it is tight.
9) Position the cups under the spouts.
10)Press the coffee dispensing button (4), light 5 goes on and wait until coff e e starts filling the cups.
11)Once the desired level has been reached, press button 4 to stop the flow and light 5 goes off.
12)Note: if the unit is to be used frequently the coffee can be left in the filter until the next serving.
If it is not used frequently, empty out the filter and clean it.
13)At this point you have finished preparation of two cups of coffee.

TROUBLESHOOTING
If your espresso coffee maker is not functioning properly, see if you can find the problem in the troubleshooting list below.
Also reread the corresponding sections in the user's manual.
Problem
The machine does not prepare the espresso coffee.
The coffee comes out of the sides of the filter holder.
There is too little or no "cream"
The "cream" is too dark and/or the coffee has a burnt flavor
The coffee is not hot enough
The pump does not suck water from the tank
Remedy
Check whether the reservoir empty light is on: no water in the reservoir, or reservoir not inserted correctly.
The coffee has been ground too fine or has been pressed too hard.
The spout is plugged.
Scale must be removed from the machine.
The filter holder was not inserted correctly.
The filter holder was not tightened enough.
Clean coffee grinds away from the gasket (see the section on cleaning).
Check the amount of coffee: the measure must be filled level.
The machine is not hot: is the heating element off?
The coffee has not been ground fine enough.
The coffee in the filter has not been pressed correctly
The coffee is not fresh.
The water is not fresh.
The coffee has been ground too fine.
The coffee has been pressed too hard.
Too much coffee has been measured.
The hot water passes through the filter too quickly. It takes 25-40 seconds to make 2 cups.
The coffee in the filter has not been pressed correctly.
The coffee has not been ground fine enough.
The filter holder is cold. The filter holder should always left inserted in the machine while the unit is heating up and during use so it remains hot.
The cups are cold. The cups must be placed on the heated shelf or preheated with hot water prior to use.
The boiler safety thermostat has cut in: contact the nearest service center.
Open the steam tap (8) and push repeatedly the coffee delivery key (4).
