Features 2.- Features Important: Optional wash features may be included, depen- ding on the range. These are to be selected after having activa- ted the required wash program. Any change of program will cancel out the previously selected wash features, even if the dishwasher is switched off at the mas- ter switch.
Page 6 Features Washing with an alternative distributor If there is a button bearing this symbol, it means that this model of dishwasher has an alternative MOTOR/DISTRIBUTOR. This button is pressed to select the option for washing either the load in the upper half of the dishwasher, the load in the lower half, or both.

Page 9 Description of all Functions Press this button repeatedly to successively increase the delay time - 3H, 6H, 9H. The corresponding pilot light will come on and remain lit. If you press the button again, the delay time will be cancelled and the DELAY pilot lights will switch off. This cycle may be repeated as often as you wish.
Page 10 Description of all Functions 3.1.3.- Pressing the <START/PAUSE> button You can stop and start the washing process as many times as you wish by repeatedly pressing the <START/PAUSE> button.

Page 11 Description of all Functions This steam coming from the inside of the dishwasher (see Figure 2 below) through the steam outlet in the upper part “A” is extracted by the fan (extraction chamber) “B”, passing through part of the Air break “C”. When the steam reaches the expulsion chamber “D”, it is expelled into the inside of the dishwasher via the steam outlet in the lower part (“E”), which in turn regulates the salt consumption in accordance with the hardness of the water.
Page 12 Description of all Functions IN CASE OF MALFUNCTIONING OR ANOMALY (for all models) In case of malfunctioning or anomaly, the dishwasher’s automatic information buzzer will help us to identify the cause of the problem. It emits a series of intermittent beeps followed by a pause of approximately 7 se- conds.
