故障原因Cause 矽膠軟管老化破裂、沖煮組密封圈硬化、熱交換器積垢滲漏、水箱底部止水閥損壞。 Aged silicone tube broken, brew group seal hardened, heat exchanger leakage, tank bottom valve damaged.

自行檢查方法Self-check 檢查水箱底膠閥狀態、定期拆解清洗沖煮組、執行完整除垢程序。 Check tank valve, clean brew group regularly, run full descaling.

維修更換零件Spare Parts 矽膠水管、沖煮組密封圈、水箱底止水閥。 Silicone tube, brew group gasket, tank bottom valve.

故障現象Symptom 水箱已經加滿清水，儀表仍然提示缺水，有時做完一杯咖啡立刻報警。 Tank full but machine still shows low water warning, alarm triggers after one cup.

故障原因Cause 水位浮子卡滯或破損、水流感應器故障、水箱接觸位髒汙導致感應失靈。 Stuck / broken float sensor, flow meter fault, dirty contact point between tank & machine.

自行檢查方法Self-check 取出水箱清洗水位浮球，擦乾機身與水箱接觸觸點。 Take out tank, clean float, wipe contact terminals.

維修更換零件Spare Parts 水位浮子總成、水流傳感器（水表）。 Float assembly, flow meter sensor.
