Page 14: First Start-Up
5 FIRST START-UP First start‐up The electrical protection system must undergo a functional test before the appliance is put into operation. The appliance must be installed and/or inspected by qualified staff, who will start it up for the first time and provide the relevant operating instructions.

Page 15: Set-Up
Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out the peristaltic pumps by placing the external intake pipes in water for a few cycles. Always use only products specifically recommended for use in a dishwasher. Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system. The internal pipes of the detergent and rinse aid pumps should be replaced by the After‐Sales Service every 12 months or 15,000 wash cycles and operation of the diaphragm can be disposed of in accordance with the relevant regulations rinse aid pump should be checked. 6 SET-UP Set‐up During first start‐up, the functions/parameters listed below must be set or adjusted: 6.1 Dishwasher parameter modification procedure: Only accessible after filling is complete or with the door open.
