PROBLEM TO BE SOLVED: To provide an endoscope cleaning device capable of performing self-check.SOLUTION: The endoscope cleaning device comprises : a cleaning disinfection tank 11 for cleaning and disinfecting an endoscope； a liquid pump P3 circulating liquid in the cleaning disinfection tank 11； liquid route valves SV8-11 arranged in a route for supplying the circulated liquid into the endoscope； and a sensor (pressure sensor PsM1, etc.) detecting a condition of the cleaning device. The endoscope cleaning device further comprises a self-check processing unit performing an initial condition check processing i.e. checking the sensor after discharging water in the cleaning disinfection tank 11 and thereafter performing circulation check processing i.e performing operation check of the liquid pump P3 and liquid route valves SV8-11 after supplying water into the cleaning disinfection tank 11.SELECTED DRAWING: Figure 3【課題】効率的にセルフチェックを実行することができるようにした内視鏡洗浄装置の提供。【解決手段】内視鏡を洗浄・消毒するための洗浄消毒槽１１と、洗浄消毒槽１１の液体を循環させる液体ポンプＰ３と、当該循環させる液体を内視鏡内へ供給する経路に設けられる液体経路バルブＳＶ８～１１と、装置の状態を検知するセンサ（圧力センサＰｓＭ１等）と、を備え、洗浄消毒槽１１の排水後に前記センサのチェックを行う初期状態確認処理を実行し、これより後に、洗浄消毒槽１１への注水後に液体ポンプＰ３と液体経路バルブＳＶ８～１１の動作チェックを行う循環確認処理を実行するセルフチェック処理部を備える内視鏡洗浄装置。【選択図】図３
