  • the dry maintain step (S200) is configured to maintain a dried state of the dishes inside the washing tub 130 by periodically operating the drying module 180 according to the user's selection, if the dishes having being washed and dried are remaining in the washing tub 130. Such the dry maintaining step (S200) may be performed for a preset time period in the daytime or nighttime. The dry maintaining step (S200) may end according to a preset operation time, a dishwasher condition and the user's selection.
  • the dry maintaining step (S200) is selected by the user and then the controller 190 is implemented to operate the dry fan 182 of the drying module 180 intermittently for a preset time period (S210).
  • the dry fan 182 is operated for ten minutes after thirty minutes of a pause time.
  • the controller 190 operates the frying fan 182 repeatedly for the preset operation time period (six hours).
  • the preset operation time of dry maintaining step (S200), the pause and duration time of the dry fan 182 may be variable according to operational conditions of the dry fan 182.
  • the controller 190 senses an ending condition of the dry maintaining step during the pause and duration time of the dry fan 182 (S220).
  • the dry maintain step (S200) may finish according to a specific condition. For example, when sensing the user's manipulation (for example, canceling of the dry maintaining step (S200), starting of another washing step, opening of the door 122 provided in the dishwasher during the dry maintaining step (S200), the controller 190 may forcibly end the dry maintaining step (S200).
  • the controller 190 determines whether the preset operation time of the dry mainlining step passes (S230).
  • the controller 190 keeps the intermittent operation of the dry fan being operated in the dry maintaining step (S200).
  • the controller 190 finishes the dry maintaining step (S200).
  • the dried state of the dishes having been under the dishwashing process or kept in the dishwasher may be maintained efficiently, so that the user can be provided with use convenience.
  • unnecessary power consumption may be prevented when sensing an abnormal state of the heater provided in the dishwasher and the operational state of the heater may be rapidly sensed.
