3) Carefully dry the walls of the tub with a cloth and put it back in its seat in the machine.
4) Insert the three tubes in the tub.
5) Fill the tub (manual mode), and again close the door of the machine.
• Do not use detergents or abrasive materials or products to clean the water tub.
• Do not place the water tub in a dishwasher.

7. Display of alarms
7.1 Model with automatic supply of water tub
In this type of machine there is an automatic level alarm for the water boiler.
In fact, if the level of the water in the steam boiler is below normal and the pump is not able to restore that
level within 4 minutes, the control unit of the machine will stop automatic filling of the boiler and signals the
anomaly by means of the blue LED on the push button panel, which comes on. At the same time, the pump for
filling the steam/water boiler is disabled, as is the electrical heating element of the eater/steam boiler. To reset
the alarm, turn the machine off and then back on again. The electronic control unit will once again attempt to
restore the level in the steam boiler. If the problem persists, contact LA SAN MARCO SPA technical service.
7.2 Model with automatic supply of the water tub
In this model, in addition to the boiler automatic level alarm described in paragraph 7.1, there is a capacitive
sensor that stops automatic filling of water when it reaches the maximum acceptable level in the tub. If, within
4 minutes, the sensor is not reached by the water level, the electronic control unit of the machine shuts down
automatic filling of the tub and at the same time closes the filling solenoid valve. The alarm is indicated by the
flashing of the blue LED located on the control keypad. The alarm can be reset by turning the main switch.
The electronic control unit will now attempt to restore the level in the tub. If the problem persists, contact LA
SAN MARCO SPA technical service.
