Abstract
A dishwasher performs a method for providing a notification for replacing a filter. The dishwasher continues to accumulate operation time of an air blowing fan of the dishwasher, and when total accumulative operation time is predetermined time or greater, outputs a notification for replacing a filter through a display or a speaker to determine the timing of the replacement of the filter accurately.
Claims18
A dishwasher comprising:
- a tub that defines a wash space therein;
- a door configured to open and close the wash space;
- a dry air supply part comprising an air blowing fan, and a filter;
- a non-transitory memory;
- and
- a processor configured to control operation of the dishwasher,
- wherein the processor is configured to:
- accumulate, in the non-transitory memory, operation time for which the air blowing fan operates and/or a number of times of a drying process based on operation of the air blowing fan, and,
- compare total operation time accumulated based on the operation of the air blowing fan with a predetermined first time and/or compare the number of times of the drying process with a number of predetermined times,
- wherein when the total accumulative operation time is greater than or equal to the predetermined first time and/or the number of times of the drying process is greater than or equal to the predetermined time, the process is configured to output an optical signal and/or an acoustic signal for replacing the filter to customer.
