GV 640 Service Manual 67
For internal use only
When the dishwasher door is opened, the trigger mechanism will “reset”. This ensures that the deter-
gent cover is opened first when the coil is next activated.
If moisture remains in the detergent box and if a de-
tergent tab is then put into the box, the tab will be-
gin to dissolve slowly.
Two plastic spacers in the box prevent detergent
from “sticking” onto the casing.
