6.2 Starting the peristaltic pumps – rapid filling of detergent and rinse aid delivery circuit
Perform after the parameter modification procedure explained in the previous point.
Indicator lights as follows:
With the dishwasher powered up, access "programming mode" by pressing the
on/off button for a few seconds; at the "beep", release the button and press it
again quickly within 0.5 seconds.
The peristaltic pumps continue to operate until the same buttons are pressed
again. The rinse aid and detergent symbol lights remain on as long as work is
in progress; bear in mind that the rinse aid peristaltic pump fills the circuit in
about 7 minutes, while for the detergent it only takes 2 minutes.
The dishwasher is able to identify a number of malfunctions and show them on the display.
If the problem persists after the dishwasher has been switched off and back on, proceed as described below:
