Abstract

A method for accelerating the wetting of washing in the variable-speed drum of a drum washing machine. A quantity of fresh water is introduced according to the determined quantity of laundry. The drum is driven at intervals and in a reversing manner in successive phases for a first determined length of time at an rpm which is adapted to the washing. The drum is stopped and/or driven at an rpm adapted to the wetting of the washing for a second pre-determined length of time, such that the water is especially effectively distributed over the washing by means of ladling devices located on the drum. The required quantity of washing liquid for the following washing phase is determined once the drum is driven at intervals and in a reversing manner at an rpm adapted to the washing after the second pre-determined length of time has come to an end.
