Abstract

본 발명은 세탁기의 수위측정오류 검출장치 및 검출방법에 관한 것으로 세탁조 내의 수위를 측정하는 수위센서, 세탁조 내로 물을 공급하거나 세탁조 내의 물을 배출하는 급배수장치 및 급배수장치를 제어하여 세탁조 내의 실제 수위를 조절하고, 실제 수위가 조절되는 동안 수위센서에서 측정되는 수위변화에 기초하여 수위센서의 측정오류를 검출하는 제어부를 포함하여 구성되며, 본 발명에 따르면, 에어트랩 내에 남아 있던 물이 얼거나 기타 에어트랩 내의 압력을 변화시키는 문제가 발생했을 때 사용자가 수위센서의 측정오류를 인지할 수 있고, 화재발생의 위험을 사전에 제거할 수 있으며, 불필요한 물과 세제의 낭비를 줄일 수 있다.
