故障原因：

Fault Reasons:

不論季節都冇熱水，點火失敗、發熱體故障、主控板異常，冬季最常見。

No hot water in all seasons, ignition failure, heating element fault, main board error, most common in winter.

自助處理方法：

DIY Solutions:

• 檢查熱水爐電源/煤氣閥是否開啟
• 查看水壓是否正常，調整入水閥
• 重置熱水爐電源，重啟系統
• 若仍無熱水，立即聯繫專業技師檢查

• Check power/gas valve is turned on
• Check water pressure, adjust inlet valve
• Reset power and restart heater
• Contact technician if no hot water

故障原因：水箱生鏽、接駁喉管老化、密封圈損耗、安全閥滲水，牆身滴水潮濕。

Fault Reasons: Rusty tank, aging pipes, worn seal, safety valve leakage, wall damp.

自助處理：立即關閉電源+入水閥，抹乾水分，聯繫我們上門更換配件。

DIY: Turn off power + inlet valve immediately, dry water, contact us for replacement.

故障原因：點火針故障、氣壓不足、風壓異常、過熱保護啟動，反覆開機都著唔到。

Fault Reasons: Ignition pin fault, low gas pressure, abnormal air pressure, overheat protection.

自助處理：檢查煤氣表/煤氣罐是否有氣，關閉重開，勿多次重試避免危險。

DIY: Check gas supply, restart once, DO NOT retry frequently (danger).

故障原因：發熱管老化絕緣不良、電路受潮、溫控器短路，一開即跳安全掣。

Fault Reasons: Aging heating element, damp circuit, thermostat short circuit.

高危警告：立即停用！關閉總掣，聯繫我們緊急維修。

DANGER: Stop using immediately! Turn off power, contact urgent repair.

原因：水壓感應器故障、流量掣老化、煤氣供氣不平均

Reason: Water pressure sensor fault, aging flow valve, unstable gas supply

處理：清潔感應器、穩定水壓，專業檢修

Solution: Clean sensor, stabilize pressure, professional repair

原因：水垢積厚、水泵老化、風扇故障、燃燒不完全

Reason: Scale build-up, aging pump, fan fault, incomplete combustion

處理：除垢、更換風扇/水泵

Solution: Descaling, replace fan/pump

原因：入水口濾網堵塞、喉管淤積水垢、機內管路積垢

Reason: Clogged filter, pipe scale, internal pipeline blockage

處理：拆洗濾網、高壓清洗管路

Solution: Clean filter, high-pressure pipeline cleaning

原因：散熱不良、溫控器失準、水垢包覆發熱件

Reason: Poor heat dissipation, faulty thermostat, scale covered heating parts

處理：停用冷卻，專業更換溫控器+除垢

Solution: Stop use, replace thermostat + descaling

原因：電子主板故障、感應線路鬆脫、控製面板失靈

Reason: Main board fault, loose sensor wire, control panel failure

處理：記錄故障碼，聯繫我們檢修主板

Solution: Record error code, contact us for board repair

高危安全問題！立即處理：

HIGH RISK! Act Immediately:

• 立即關閉煤氣閥+電源
• 開窗通風，切勿開關電器
• 遠離現場，緻電我們緊急上門

• Turn off gas + power immediately
• Open windows, DO NOT operate any electronics
• Leave area, call urgent service
