GENERAL INFORMATION

These models are integrated front loading dishwashers providing a choice of eleven wash

programmes to suit load requirements.

The programme selection button, On/Off switch and Programme Display and Option Buttons are

mounted along the top edge of the door panel.

The programmes are selected by depressing the programme selection button (P). The programme

can be cancelled at any time by holding down the On/Off button until the buzzer sounds three times

- resetting the programme.

The selected programme is indicated by a number displayed on the top edge of the door panel.

At the end of the programme the buzzer sounds twice and the selected programme flashes once a

second to indicate the end of the programme.

Water hardness is adjusted by the user before the machine is first used.

ECODESIGN REGULATION

The ECO wash cycle is the standard cycle to which the energy label data refers. It can be used to

wash crockery with a normal soil level and is the most efficient cycle in terms of energy and water

consumption for this type of crockery.

To reduce consumption even further, only run the dishwasher when it is full.

Standby consumption: Left-on mode consumption: 5 W - Off mode consumption: 0.5 W

Consumption data table for the main cycles:

*Cycle data refers to the values recorded in a laboratory in accordance with European standard EN 50242.

** Data is obtained by recording values when the appliance is operational and loaded with user crockery.
