  • the filtering member enables filtering of dirty water.
  • a lesser amount of dirt is conveyed to the microfilter.
  • the filtering member enables increasing the pressure of the water while being conveyed through the conduit to the chamber. By this, the water collides more rapidly on the microfilter due to its pressure being increased while passing through the filtering member. Thus, the microfilter is also flushed with high-pressure water.

  • Filtering member (6) is removably attachable. By this, the filtering member (6) is enabled to be removed and cleaned.
  • the dishwasher (1) comprises a conical shaped filtering member (6) having a diameter tapering from the conduit (4) to the chamber (3).
  • the filtering member (6) has a diameter which tapers from the conduit (4) to the chamber (3). By this, the water is enabled to leave the narrowed down diameter with a higher pressure.
  • the microfilter (5) is flushed with pressurized water.

  • a dishwasher (1) comprising an automatic microfilter (5) cleaning system is realized with the present invention.
  • the water conveyed to the chamber (3) is freed from larger particles and is pressurized by being passed through the filtering member (6).
  • cleaner water with higher pressures is conveyed to the microfilter (5) provided in the center of the chamber (3).
  • the microfilter (5) is flushed by means of sending high-pressure water on the microfilter (5). Washing performance is enhanced thanks to the microfilter (5) remaining clean at all times.
