Abstract

본 발명은 일련의 세탁행정시 세탁도중에 필터의 막힘 상태를 사용자에게 알려줄 수 있도록 한 세탁기의 필터막힘감지방법에 관한 것으로, 본 발명은 일련의 세탁행정시 초기급수가 완료된 상태에서의 수위에 대하여 수위센서로 주파수를 감지하고, 이어서 세탁도중에 순환 급수되는 수위에 대하여 수위센서로 주파수를 감지하는 단계와, 상기 단계에서 감지된 초기 수위센서의 주파수와 세탁도중에 감지된 스위센서의 주파수와의 주파수 차를 계산하여 이 계산된 주파수차가 기설정된 소정의 주파수 이상일 경우 필터막힘을 경보하도록 이루어짐을 특징으로 한다.
