Troubleshooting

Malfunctions and possible causes

To ensure the best possible coffee quality, it is necessary to clean and

decalcify the coffee maker regularly.

Before having the machine repaired, please check the following points:

• Does the coffee maker not switch on?

• The power plug is not properly connected.

• The main power switch (on the left-hand side) is not set to ON.

• Check fuses.

• Does the indicator ﬂash?

• The brew unit has not been properly inserted.

• The door is not properly closed.

• Does the indicator light up and does a message appear on the

display?

• This fault can only be rectified by a qualified service technician.

• Do the indicators flash/light up; do display messages appear?

• Check the indicator symbols on page 44 (for their meaning).

•

Is the pump causing loud noises and/or does the indicator light up?

• The water tank has not been properly inserted (air in the system).

Siena 2:

•

Bleed the device using the

hot water button (press for ± 6 sec.).

(The indicator goes out when the next beverage is dispensed).

Siena 1:

• Turn the rotary dial (on the right-hand side) to the [ Hot water ]

position in order to bleed the device.

It is normal when the water pump starts up from time to time during

operation; it is ﬁlling the system with water.

• Is there no milk foam (Siena 2)?

• The milk nozzle is clogged (in the milk container).

Insert a brush into the milk nozzle (refer to page 75).

Is the milk only hot (Siena 2)?

• The foam nozzle on the milk foam producer is clogged.

Insert the air valve pin into the milk nozzle (refer to page 53).

• Does the milk foam have large bubbles (Siena 2)?

• The milk is too warm (always keep milk in the refrigerator).

(Optimal milk temperature: 3 °C to 5 °C).

• The O-rings on the milk foam producer are defective.

Check the O-rings and replace them, if necessary.

• The milk suction tube is defective. Check the milk tube and

replace it, if necessary.

• The milk nozzle (diameter) is too small.

• Is the milk foam too cold (Siena 2)?

• The milk nozzle is defective or a nozzle of the wrong diameter

has been fitted.

• Does the coffee not have any foam?

• The cups are too cold (pre-heat the cups for ideal foam).

• The operating temperature (indicator is lit) has not yet been

reached.

• The coffee is no longer fresh.

• The coffee grinder setting is too coarse (high number).

• The coffee grinder setting is too fine (low number).

• The wrong coffee mixture is being used.
