常見原因：電源線鬆脫、保險絲燒毀、電機線圈燒壞、開關按鈕故障、主板供電異常。

建議處理：先檢查插座與電源線是否正常，更換插座測試；如仍無反應，可能是內部電路或馬達故障，建議交由專業師傅檢測，避免自行拆機導致漏電風險。

Causes: Loose power cord, blown fuse, burnt motor coil, faulty power switch, abnormal mainboard power supply.

Suggestion: Check power outlet and cord first. If still not working, internal circuit or motor failure is likely. Professional inspection recommended.

常見原因：刀盤磨損嚴重、軸承潤滑不足或損壞、異物卡入刀盤、馬達齒輪磨損、機身螺絲鬆動產生共振。

建議處理：立即停用，檢查豆倉內是否有石頭或金屬異物；如無異物，多為刀盤或軸承老化，需更換原廠配件。長期高噪音使用會加速馬達損耗。

Causes: Worn burrs, insufficient bearing lubrication or damage, foreign objects stuck, gear wear, loose screws causing resonance.

Suggestion: Stop use immediately. Check for foreign objects in hopper. If clear, burrs or bearings likely need replacement.

常見原因：刀盤磨損變形、刀盤安裝偏移、研磨度調節機構鬆動、進豆速度不均勻。

建議處理：先校正研磨度調節環，確認零點位置；如仍不均，檢查刀盤是否有崩缺或磨損痕跡，一般刀盤使用1-2年或研磨500-1000kg咖啡豆後建議更換。

Causes: Worn/deformed burrs, misaligned burr installation, loose grind adjustment mechanism, uneven bean feed rate.

Suggestion: Recalibrate grind adjustment and zero point. If still uneven, inspect burrs for chips. Burrs should be replaced every 1-2 years.

常見原因：咖啡豆油脂過高黏結、豆形過大卡於進料口、濕氣導致粉結塊堵塞出粉口、攪粉器故障。

建議處理：先清空豆倉，用乾刷清理進料通道；避免使用過度新鮮或油脂極高的豆子；如經常卡豆，可能是進料口設計或刀盤角度問題，可由師傅調整。

Causes: Oily beans sticking, oversized beans jamming feed chute, moisture causing clogs, agitator failure.

Suggestion: Empty hopper and clean feed channel with brush. Avoid extremely fresh/oily beans. Persistent jams may need adjustment by technician.

常見原因：調節螺紋磨損滑牙、彈簧彈性疲乏、定位鋼珠脫落、調節環斷裂。

建議處理：切勿強行轉動以免損壞螺紋；此屬精密機械部件，需拆解檢查更換磨損零件，並重新校準零點位置。

Causes: Worn adjustment threads, fatigued spring, lost positioning ball, broken adjustment ring.

Suggestion: Do not force turn to avoid thread damage. This precision part requires disassembly, replacement and recalibration.

常見原因：定量計時器飄移、光電感應器髒污失靈、馬達轉速不穩、殘粉堆積影響計量。

建議處理：先清理粉道殘粉與感應器；如為定時款磨豆機，需重新校準計時參數；商用機型建議每三個月進行一次定量校準。

Causes: Timer drift, dirty photo sensor, unstable motor RPM, retained powder buildup affecting dosing.

Suggestion: Clean powder chute and sensor. For timed grinders, recalibrate timer parameters. Commercial models recommended quarterly calibration.

常見原因：馬達過熱燒毀、線路短路、電容擊穿、刀盤摩擦生熱過度。

建議處理：立即斷電停用，切勿繼續使用以免起火！此為嚴重故障，多為馬達絕緣層破損或電路短路，需專業檢修更換馬達或電源板。

Causes: Overheating burnt motor, circuit short circuit, capacitor breakdown, excessive burr friction heat.

Suggestion: Unplug immediately! This is a serious fault, usually motor insulation damage or short circuit. Requires professional repair.

常見原因：環境濕度太低、塑膠粉杯靜電累積、刀盤產生靜電、咖啡豆過乾。

建議處理：可使用防靜電噴劑處理粉杯，或噴少量水霧於豆倉；部分高階機型有除靜電裝置，如故障可更換離子風扇或導電部件。

Causes: Low humidity, static buildup in plastic doser, burr-generated static, overly dry beans.

Suggestion: Use anti-static spray on doser or mist beans lightly. Higher-end models have anti-static devices that can be replaced if faulty.

常見原因：啟動電容衰減、馬達碳刷磨耗、軸承阻力過大、電壓不足、電機線圈局部短路。

建議處理：先確認供電電壓正常；如碳刷磨損可更換碳刷恢復動力；電容衰減是常見老化現象，更換啟動電容即可解決。

Causes: Weak start capacitor, worn motor brushes, excessive bearing resistance, low voltage, partial motor coil short.

Suggestion: Verify supply voltage first. Worn brushes can be replaced. Capacitor decay is common aging and easily fixed by replacement.

常見原因：擋粉膠片磨損變形、粉倉密封條老化、定量撥片間隙過大。

建議處理：更換擋粉矽膠片與密封條；調整定量撥片間隙，確保每次撥粉乾淨不留殘粉。

Causes: Worn flap gasket, aged doser seals, excessive dosing blade gap.

Suggestion: Replace silicone flap and seals. Adjust dosing blade gap for clean powder cutoff.

常見原因：咖啡粉滲入按鍵縫隙造成氧化、觸控膜進水受潮、主板按鍵電路故障。

建議處理：切勿用大量水沖洗面板；可先用乾毛刷清理縫隙粉塵；如仍失靈需更換按鍵膜或控制面板總成。

Causes: Coffee powder seeping into buttons causing oxidation, moisture damage to touch membrane, keypad circuit failure.

Suggestion: Do not wash panel with water. Clean gaps with dry brush. If still faulty, replace keypad membrane or control panel.

常見原因：馬達過熱保護啟動、散熱風扇故障、連續工作時間超過額定負載、環境通風不良。

建議處理：檢查散熱風扇是否運轉，清理進風口灰塵；商用機型避免超時連續研磨；如頻繁保護，可能是馬達老化或熱敏開關靈敏度異常。

Causes: Motor thermal protection activated, cooling fan failure, exceeding duty cycle, poor ventilation.

Suggestion: Check cooling fan operation and clean air intake. Avoid excessive continuous use. Frequent trips may indicate aging motor.

常見原因：刀盤固定螺絲鬆動、刀盤崩缺斷裂、軸承竄動量大、轉子軸向竄動。

建議處理：立即停用！繼續使用會徹底損壞刀盤與馬達軸心；需拆解檢查刀盤狀態，鎖緊固定螺絲或更換受損刀盤。

Causes: Loose burr mounting screws, chipped/broken burrs, excessive bearing play, rotor axial movement.

Suggestion: Stop immediately! Continued use will destroy burrs and motor shaft. Disassemble to inspect, tighten or replace damaged burrs.

常見原因：刀盤磨損鋒利度下降、研磨度設置過細、刀盤平行度偏差、轉速過高。

建議處理：適當調粗研磨度；如刀盤已使用超過兩年，建議更換新刀盤可大幅減少細粉，提升研磨均勻度。

Causes: Dull worn burrs, grind setting too fine, burr parallelism misalignment, excessive RPM.

Suggestion: Slightly coarsen grind setting. If burrs are over 2 years old, replacement will significantly reduce fines and improve uniformity.

常見原因：密封膠條老化變形、塑膠外殼開裂、豆倉蓋卡扣斷裂。

建議處理：更換老化密封膠條，修補或更換開裂外殼；潮濕季節建議不要存放過多咖啡豆於豆倉，保持乾燥。

Causes: Aged seal gasket, cracked plastic housing, broken hopper lid latches.

Suggestion: Replace aged seals, repair or replace cracked housing. Avoid storing large amounts of beans in hopper during humid season.

常見原因：不同品牌代碼含義不同，常見有馬達過熱、感應器異常、計量錯誤、通訊故障等。

建議處理：記下錯誤代碼編號，聯絡我們提供對應品牌型號的故障代碼查詢；切勿隨意清零忽略，可能隱藏更大故障。

Causes: Varies by brand — common ones are motor overheat, sensor errors, dosing faults, communication issues.

Suggestion: Note the error code and contact us for brand-specific diagnosis. Do not just reset and ignore underlying issues.

常見原因：粉道設計死角多、通道內壁不光潔、靜電吸附、擋粉片角度問題。

建議處理：定期用氣吹清理粉道；可升級改裝低殘粉出粉口或塗層處理；部分型號有原廠低殘粉改裝套件可供更換。

Causes: Many dead ends in chute design, rough inner walls, static adhesion, flap angle issues.

Suggestion: Regularly blow out chute with air. Low-retention chute upgrades or coatings available for some models.

常見原因：底腳防滑墊脫落、機身內部配重偏移、馬達轉子動平衡不良、檯面不平。

建議處理：更換防滑吸盤底腳，放置於平整檯面；如震動異常劇烈，需檢查馬達轉子動平衡與軸承磨損狀況。

Causes: Missing anti-slip feet, internal weight imbalance, motor rotor imbalance, uneven countertop.

Suggestion: Replace suction cup feet, place on level surface. Severe vibration needs rotor balance and bearing inspection.

常見原因：軸承潤滑油乾涸阻力變大、內部積塵受潮、電容容量衰減、接線端子氧化接觸不良。

建議處理：長期閒置後首次使用建議先空轉短時間潤滑軸承；如頻繁停機需保養更換潤滑脂與檢查電路接點。

Causes: Dried bearing grease increasing resistance, dust/moisture buildup, weakened capacitor, oxidized terminal connections.

Suggestion: After long storage, run briefly empty to lubricate bearings. Persistent stopping needs bearing regreasing and electrical check.
