Definitions

  • the solution is based on a water-conducting household appliance, in particular a dishwasher, at least comprising a pump, with which in at least one normal operating mode liquid is conveyed.
  • the control device can control the liquid pump with a venting signal.
  • the vent signal may preferably be located directly upstream of the actual start signal, so that after the venting, the actual start of operation of the liquid pump begins, in which the pump is continuously raised to the maximum flow rate.
  • the jerky rotational movement of the impeller can be done without building up a fluid pressure with which a pressure-side check valve element is opened.
  • the pressure-side check valve element separates the hydraulic circuit of the dishwasher from the sewage network.
  • the drain pump 19 is shown out of service, so that the impeller 37 is stopped.
  • a residual liquid column h builds up in the pump chamber 35, above which a gas bubble remains.
  • the gas bubble is trapped in the upper apex area of the pump chamber 35 and in the transition to the pressure port 39.
  • a impeller blade partially protrudes into the gas bubble.
  • the drain pump 19 is activated during the wash cycle for a liquid change, which takes place after execution of a partial program step, such as the pre-wash, and before the start of the subsequent part program step, such as cleaning.
