To provide a water server in a configuration having two-stage valve mechanisms consisting of a first valve mechanism and a second valve mechanism on an upstream side and a downstream side of a beverage flow channel, in which a control unit can recognize which of the first and second valve mechanism has failed more quickly.SOLUTION: A water server of this invention comprises: a beverage water tank that retains beverage water; a beverage water flow channel including a water discharge nozzle R43; openable/closable first magnetic valves V11 to V13 disposed on an upstream side relative to the water discharge nozzle R43 in the beverage water flow channel; an openable/closable second magnetic valve V2 disposed in the water discharge nozzle R43; a capacitive sensor S that can detect beverage water in an inter-valve mechanism area W; and a control unit 50 that determines that a leakage of the beverage water has occurred in any one of the first magnetic valves V11 to V13 and the second magnetic valve V2 based on a detection result by the capacitive sensor S after performing the valve-closing control of closing both the first magnetic valves V11 to V13 and the second magnetic valve V2.SELECTED DRAWING: Figure 3 【課題】飲料水流路の上流側と下流側とで第１弁機構及び第２弁機構といった２段階の弁機構を有する構成において、制御部が、第１弁機構及び第２弁機構のいずれが故障しているかをより早く認識することができるウォーターサーバを提供する。【解決手段】ウォーターサーバは、飲料水を貯留する飲料水タンクと、出水ノズルＲ４３を含む飲料水流路と、飲料水流路のうち出水ノズルＲ４３よりも上流側に設けられ開閉可能な第１電磁弁Ｖ１１〜Ｖ１３と、出水ノズルＲ４３に設けられ開閉可能な第２電磁弁Ｖ２と、弁機構間領域Ｗの飲料水を検知可能な静電容量センサＳと、第１電磁弁Ｖ１１〜Ｖ１３及び第２電磁弁Ｖ２の双方について弁を閉じる弁閉制御を行った後に、静電容量センサＳの検知結果に基づいて、第１電磁弁Ｖ１１〜Ｖ１３及び第２電磁弁Ｖ２のいずれかで飲料水の漏れが発生していると判断する制御部５０と、を備える。【選択図】図３
