  • Method 200 includes, as a third method step, increasing 205 minimum pump speed 155 to maximum pump speed 159 by controller 119 during a third time period 151 subsequent to second time interval 149 when the volume flow of wash fluid pumped by variable speed pump 117 reaches volume flow minimum threshold 157, wherein the maximum pumping speed 159 is greater than the minimum pumping speed 155 and the nominal pumping speed 141 to remove an air swirl in the variable speed pump 117.
  • the method 200 includes, as a fourth method step, reducing 207 the maximum pumping speed 159 of the variable speed pump 117 to the nominal pumping speed 141 by the controller 119 during a fourth time period 153 subsequent to the third time period 151 when the volume flow of the washing fluid pumped by the variable speed pump 117 is Nominal volume flow 143 reached to again pumping washing liquid with the nominal volume flow 143 from the tub 105 and through the line 115.
