circulating in the receptacle.

Carefully clean the stainless steel parts with a damp cloth, water and soap or common, non-abrasive chlorine or ammonia based

detergents.

7 MAIN CAUSES OF OPERATING FAILURE

Should the appliance fail to produce ice, before calling on the Authorized Technical Service Centre, first check carefully that:

• the water supply tap(s) (7 in Fig. 3), fitted during the installation phase, has/have been turned on

• check that there is no power cut, the plug (if any) is correctly inserted in the socket, the switch (6 in Fig. 3) is in the “ON” position,

and the pushbutton (18 in Fig 2) is illuminated

• check that the rotation sensor is not signalling an alarm

Furthermore:

• if there is excessive noise, make sure that the appliance is not touching furniture or sheet metal which can give rise to noise or

vibrations

• should any trace of water appear, check the drain hole of the bin to ensure that it is not clogged, that the water fill and drain

pipes are correctly connected and are not throttled or damaged

• make sure that the temperature of the air or water does not exceed the installation limit values (see paragraph 5.2)

• make sure that the water inlet filter is not clogged (see paragraph 9.1)

If the fault still persists after the above inspections have been made, turn off the electric power source by means of the switch

fitted during the installation phase, pull out the plug (if any) from its socket, turn off the tap(s) connecting the appliance to the water

mains, and contact the nearest Authorized Technical Service Centre.
