Abstract (en)
[origin: EP0711860A1] Clothes washing machine, particularly for residential use, comprising a washing tub, an outlet conduit arranged under said tub, an analogue pressure sensor adapted to measure the pressure existing in a lower level of said conduit, a drain pump adapted to discharge the liquor contained in said conduit outside, wherein during the spin-extraction phase the drain pump is stopped at regular intervals, a waiting period being started each time that the operation of said pump is restored and said pressure being detected at the end of such waiting period. This operating sequence is repeated several times, the pressure difference being calculated on the basis of the pressure values detected in two subsequent measurement moments for each one of said sequences and then compared with a pre-determined value. <IMAGE>
