Page 13: 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 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 hood open. ... - Page 14 Washing temperature (tank temperature) Quantity of rinse aid dispensed, OPT, only if installed (the number indicates the number of seconds for which the peristaltic pump is operated) Quantity of detergent dispensed, OPT, only if installed (the number indicates the number of seconds for which the peristaltic pump is operated) Start‐on/start‐off Set at “on” to start the cycle when the hood is closed.
