Abstract (en)
The present invention relates to a method for washing laundry in a laundry washing machine (1) of the type comprising a washing tub (3) external to a rotatable washing drum (4) adapted to receive laundry and a draining device (25) comprising a draining pump (26) for draining liquid from the washing tub (3). The method comprises at least a draining phase (148) for draining liquid from the washing tub (3) by means of said draining device (25). The draining phase (148) comprises the steps of: a) activating (182) the draining pump (26); b) checking (185) the drainage flow rate (FR) of the liquid flowing through the draining pump (26); if the drainage flow rate (FR) is above or equal to a minimum flow rate threshold, then d) operating (199) the draining pump (26) and de-activating (186) the draining pump (26) when an end-draining condition is reached (194), if the drainage flow rate (FR) of the liquid flowing through the draining pump (26) is below a minimum flow rate threshold, then: e1) operating (184) the draining pump (26) for an on-time period (TON); e2) de-activating (186) the draining pump (26); e3) stopping (188) the draining pump (26) for an off-time period (TOFF; TOFF(n)); and e4) going back to step a).
