A laundry treatment machine comprising - a drum, - an air circulation duct through which circulation of processing air is effected, - a closed cycle fan circulating processing air, - an air-cooled condenser and an outer air duct along which an open cycle fan functions, said air-cooled condenser having a main housing comprising at least a first drying channel longitudinally extending adjacent to a first side of the main housing and a second drying channel longitudinally extending adjacent to a second side of said main housing, the first drying channel and the second drying channel being disposed in a spaced manner between said first side and second side of the main housing such that at least one cooling channel is interposed thereinbetween, - an inlet tube of the condenser, - a water jet device disposed within an outlet tube of the condenser with a plurality of nozzles (17, 18) facing said main housing thereof, said water jet device comprises at least a first nozzle disposed in an orientation such that it extends and provides water jets in a direction substantially parallel to the longitudinal axis of said first drying channel and at least a second nozzle disposed in an orientation such that it extends and provides water jets in a direction substantially parallel to the longitudinal axis of said second drying channel, thus being suitable for directly cleaning the first and second drying channels with water jets, characterized in that: - the inlet tube of the condenser is provided with a neck portion directly mountable to the main housing of the condenser such that an inner protruding part thereof provides that the first drying channel extending longitudinally adjacent to the first side of the condenser's main housing has a flush abutting relationship with said neck portion, - the inner protruding part of the neck portion is disposed on the upper part of the inlet tube to have a flush mating relationship with the first drying channel for guiding the water jets from the first nozzle down into the inlet tube, - the trajectory of water jets produced by the first nozzle is delimited by a linear transition surface while passing from the main housing into the inlet tube, and in that - the neck portion is not narrowed with a similar inner protruding part at the lower part of the inlet tube. -
