摘要： A dishwasher appliance and method of operation is provided. The dishwasher appliance may include a tub defining a wash chamber, a coarse filter disposed, a recirculation pump, and a drain pump. The method may include activating the recirculation pump to flow wash fluid through the coarse filter in a primary flow direction, and activating the drain pump to flow wash fluid through the coarse filter in the primary flow direction for an initial purge cycle. Further included may be flushing wash fluid through the coarse filter and into the tub in a secondary flow direction opposite from the primary flow direction. Still further included may be activating the recirculation pump to flow wash fluid through the coarse filter in the primary flow direction, and activating the drain pump to flow wash fluid through the coarse filter in the primary flow direction for an additional purge cycle.

摘要： A dishwasher includes a controller controlling a cleaning cycle, a screen system for filtering a wash fluid, a circulation chamber and a collection chamber in fluid communication with the circulation chamber via a screen arrangement, a circulation pump for circulating the wash fluid and a drain pump for pumping out the wash fluid. During the cleaning cycle, to detect blockage in the screen arrangement, a degree of transmission in the circulation chamber filled with wash fluid is determined with an optical turbidity sensor in a first measuring step. The wash fluid is then pumped out of the collection chamber and the degree of transmission in the circulation chamber is again determined in a second measuring step. The change in the degree of transmission from the first measuring step to the second measuring step is then evaluated.
摘要翻译：洗碗机包括控制清洁循环的控制器，用于过滤洗涤液的筛网系统，循环室和通过筛网装置与循环室流体连通的收集室，用于循环洗涤流体的循环泵和排水泵用于泵出洗涤液。在清洁循环期间，为了检测屏幕布置中的阻塞，在第一测量步骤中用光学浊度传感器确定填充有洗涤流体的循环腔中的透射程度。然后将洗涤流体从收集室泵出，并且在第二测量步骤中再次确定循环室中的透过程度。然后评估从第一测量步骤到第二测量步骤的传输程度的变化。
