1. Turn machine off, wait until the display is blank.
2. Open the door and hold a pencil or similar item against the door switch shaft.
3. Switch on and as soon as the display appears press the door switch shaft 5 times within 4 seconds.
4. The display should change to “rinse overlap”, thus showing you are in the Engineering Mode.
Scrolling through the menu is achieved by use of the two switches mentioned above; it must be switched off (“down” position) to stop the scrolling.
DANGER: DO NOT start the FILL test or the WASH PUMP test by pressing the door switch button. Close the door instead because water will start spraying.
NOTE: If it is necessary to abandon a test or other operation in the Service Mode, or when you wish to revert to normal use, switch OFF and ON again.

IMPORTANT: To avoid wasting chemicals, remove tubes from soap and rinse-agent bottles before using the Service Mode. The sys- tem will always give an initial dose during the first cycle after switch-on, even though the wash tank may still be full.
