Abstract (en)
[origin: CN112127120A] The invention relates to an operating method and a laundry treatment apparatus. The laundry treatment apparatus has a lye container with a discharge opening and an inlet element, a pump device, a discharge line connecting the discharge opening to the pump device, a pump-out line connecting the pump device to an outer region of the laundry treatment apparatus, and a circulation pumping line connecting the pump device to the inlet element. The pump device has a first pump, which pumps the washing liquid from the lye container via the pump-out line and from the laundry treatment apparatus, and asecond pump, which feeds the washing liquid from the lye container again via the circulation pumping line and via the inlet element. One pump is activated in a first period of time to pump the washingliquid into the pump-out line or a liquid level in the circulation pumping line. The other pump is activated in the second time period, and the washing liquid is pumped from the pumping-out line or the circulating pumping line to the liquid material level in the other line corresponding to the pumping-out line or the circulating pumping line.
