運水煙罩使用時出現漏電現象，觸摸機身有電擊感，可能是電線老化、絕緣層破損或接地不良導致。 Electric shock when touching the kitchen hood during use, possibly caused by aging wires, damaged insulation, or poor grounding.

開啟運水煙罩後不久，電源總制或漏電保護器就跳閘，無法正常使用，可能是線路短路、電機故障或負載過大。 Circuit breaker trips shortly after turning on the kitchen hood, possibly caused by short circuit, motor failure, or overload.

按下電源按鈕後，運水煙罩毫無反應，指示燈不亮，無法啟動，可能是電源線故障、插座問題或內部電路板損壞。 No response when pressing the power button, indicator light not on, possibly caused by power cord failure, socket problem, or internal circuit board damage.

運水煙罩運轉時風機發出異常噪音，如吱呀聲、撞擊聲或轟鳴聲，影響使用體驗，可能是葉輪積油、軸承磨損或安裝不穩。 Abnormal noise from the fan during operation, such as squeaking, knocking, or roaring, possibly caused by oil accumulation, bearing wear, or unstable installation.

運水煙罩通電後風機不轉動，無法進行吸油煙工作，可能是電機燒毀、傳動機構卡滯或控制開關故障。 Fan does not rotate after power on, unable to extract oil fumes, possibly caused by motor burnout, stuck transmission mechanism, or control switch failure.

運水煙罩使用後積水無法順利排出，導致機內積水、發臭或漏水，可能是排水管堵塞、排水泵故障或傾斜角度不當。 Water cannot be drained smoothly after use, causing water accumulation, odor, or leakage, possibly caused by blocked drain pipe, faulty drain pump, or improper tilt angle.

水泵無法正常工作，導致運水煙罩水系統癱瘓，需要更換水泵組件，確保水路循環暢通。 Water pump fails to work normally, causing the water system to malfunction, requiring pump replacement to ensure smooth water circulation.

運水煙罩運轉正常但吸油煙效果差，油煙無法及時排出，影響廚房環境，可能是濾網堵塞、風機轉速不夠或排煙管道堵塞。 Normal operation but poor smoke extraction effect, possibly caused by clogged filter, insufficient fan speed, or blocked exhaust pipe.

運水煙罩電源正常，但部分或全部按鍵無反應，無法調節風速、開啟燈光等，可能是按鍵面板損壞或控制電路故障。 Power is normal but some or all buttons are unresponsive, possibly caused by damaged button panel or control circuit failure.
