Abstract
A dishwasher with a wash tub (3) connected on the bottom to a collection well (4) into which extends the outlet duct (8) of a discharge pump (6) fitted with a nonreturn valve (11) accessible from the inside of the wash tub. The valve consists of a box-like housing (12) made in one piece with the outlet duct (8) which, in turn, is made in one piece with the well (4). The valve (11) has a flat flexible-membrane plug (18) with a tail (19) hooked to a peg (21) made in one piece with the box-like body (12). A protrusion (22) of the cover (13) for the box-like body (12) is in contact with the peg (21) to block the membrane (18) in position.
