<p>A device for controlling the feed of washing liquid in a dishwasher machine comprises a first tank (12) branching off at the supply of liquid from a feed solenoid valve (3) to a washing tub (1) of the dishwasher in order to receive a first smaller fraction of the liquid, and level detector means (13,14,17), related to the first tank, for commanding the closure of the feed solenoid valve (3) when the level of the liquid in the first tank (12) exceeds a first preset level (L1); the first tank (12) is connected to the washing tub (1) by valve means (16) suitable for allowing the passage of a flow of liquid from the first tank (12) to the tub (1) but not vice versa, and which, during feeding of the liquid, are maintained open by the flow of liquid which flows from the first tank (12) to the tub (1), so that the level of liquid in the latter coincides with the level of the liquid in the first tank (12); the first preset level (L1) is the level of liquid which is required in the washing tub (1) at the end of the feed. <IMAGE></p> |
