Common Causes:

Loose plug, faulty socket, blown fuse, loose tank safety switch, broken power cord

DIY Steps:

1. 更換其他家電測試插座是否有電
2. 重新拔插電源插頭，確保完全插實
3. 取出水箱再重新安裝到位，扣緊安全蓋
4. 檢查機身底部電源保險絲外觀是否燒黑

1. Test socket with other electrical device
2. Replug power cord firmly
3. Remove & reinstall water tank tightly
4. Check if internal fuse is burnt black

Causes:

Dirty clogged filter, high humidity setting, broken compressor capacitor, faulty humidity sensor, refrigerant leak

DIY Fix:

1. 取出濾網清水沖洗風乾再裝回
2. 將機器濕度設定調至40%-50%
3. 關機休息30分鐘後重啟觀察壓縮機是否運轉

1. Take out filter, wash & fully dry before install
2. Adjust humidity setting to 40%-50%
3. Power off 30 mins then restart to check compressor

Causes: Extremely high indoor humidity, sensor drift, dirty full water sensor, poor heat dissipation

DIY: Clean water float sensor, leave 10cm gap around unit, lower humidity target

Causes: Stuck float, limescale on float, oxidized sensor electrode, loose tank placement

DIY: Tap float to unstick, soak with white vinegar to remove scale, re-seat tank firmly

Causes: Clogged drain tray, kinked drain pipe, cracked tank, limescale blockage, uneven placement

DIY: Level the machine, unclog drain pipe, clean drain tray, inspect tank for cracks

Causes: Burnt fan motor, faulty fan capacitor, dust stuck fan blade, broken fan switch

DIY: Power off, manually spin blade to remove dust, restart test; still no spin requires repair

Causes: Uneven floor, deformed fan blade, aged compressor rubber mount, loose internal parts

DIY: Adjust feet to level unit, check fan blade for stuck foreign objects

Causes: Moldy filter/evaporator, thick dust, overheating wiring, dirty water tank

DIY: Clean filter, evaporator & tank, run max fan speed 2 hours for ventilation

Causes: Faulty temp/humidity sensor, mainboard error, loose wiring connection

DIY: Power off 10 mins to reset; recurring error code needs professional mainboard inspection

Causes: Clogged filter, dusty condenser, low refrigerant, room size over unit capacity, open windows/doors

DIY: Deep clean filter & condenser, close doors/windows to block external moisture

Causes: Operation under low temperature, broken defrost sensor, mainboard program error

DIY: Power off to melt ice naturally, avoid long run below 18°C; persistent ice requires repair

Causes: Dead remote battery, dusty infrared receiver, broken remote crystal

DIY: Replace new batteries, wipe dust off IR receiver window

Causes: Dead mainboard clock battery, system freeze, unresponsive buttons

DIY: Power off 10 mins to reset machine system

Causes: Oxidized wet buttons, aged membrane switch, moisture damaged wiring

DIY: Power off & leave half day to dry moisture; still faulty needs control panel replacement

Causes: Drifted humidity sensor value, abnormal mainboard logic program

DIY: Power off reset, use manual humidity setting as temporary solution

Causes: Clogged drain pipe, pipe placed too high, broken drain pump (pump model)

DIY: Unclog pipe, keep full pipe downward sloping without high bends

Causes: Moisture damaged broken wiring, faulty ground plug, aged compressor insulation

DIY: Cut power immediately, stop usage, contact repairman for safety wiring inspection

Causes: Insufficient heat dissipation, compressor overheat protection, unstable voltage, short-circuited capacitor

DIY: Remove surrounding obstacles for ventilation, cool down 30 mins before restart

Causes: Aged screen backlight, broken backlight resistor, loose panel wiring

DIY: Power off restart test; still dim screen needs display panel replacement

Causes: Limescale overflow on evaporator, shifted drain tray, fallen condensate pipe

DIY: Power off, remove tray for full limescale cleaning, check condensate pipe connection
