可能原因包括：電源線鬆脫或損壞、保險絲燒斷、電源開關故障、馬達燒毀或內部電路板故障。建議先檢查插頭與插座是否正常，更換插座測試；若仍無反應，請勿自行拆機，交由專業維修人員檢測電源模組與馬達狀態。

Possible causes: loose or damaged power cord, blown fuse, faulty power switch, burnt motor or internal circuit board failure. First check plug and socket, try a different outlet. If still no response, do not disassemble by yourself. Let professional technicians inspect the power module and motor condition.

常見原因：刀盤磨損嚴重導致金屬摩擦、軸承潤滑不足或磨損、異物卡入刀盤、馬達齒輪磨損。建議立即停止使用，檢查豆倉內是否有石頭或金屬異物；如無異物則大概率是刀盤或軸承問題，需盡快更換，否則會加劇馬達損耗。

Common causes: severely worn burrs causing metal friction, insufficient bearing lubrication or wear, foreign objects stuck in burrs, worn motor gears. Stop using immediately. Check for stones or metal objects in hopper. If clear, likely burr or bearing issue. Replace promptly to avoid further motor damage.

主要原因：刀盤磨損變形、刀盤固定螺絲鬆動導致偏移、研磨度調節機構磨損、刀盤安裝不平行。商用高用量機型一般使用6-12個月需檢查刀盤狀態，家用可2-3年更換。建議先重新校準研磨度，若無改善則需更換刀盤或調節組件。

Main causes: worn or deformed burrs, loose burr screws causing misalignment, worn grind adjustment mechanism, non-parallel burr installation. Commercial machines need burr inspection every 6-12 months; home use every 2-3 years. Try recalibrating first. If no improvement, burrs or adjustment assembly need replacement.

可能原因：咖啡豆太油膩結塊、研磨度調得太細、出粉口積粉堵塞、螺旋輸送器磨損、靜電嚴重造成粉結團。處理方式：先清空豆倉與粉道，用毛刷清潔刀盤與出粉通道；檢查研磨設定是否過細；如經常堵塞可能是刀盤變鈍或輸送結構磨損，需更換零件。

Possible causes: oily beans clumping, grind setting too fine, powder buildup in chute, worn auger, severe static causing clumping. Solution: Empty hopper and chute, clean burrs and path with brush. Check if grind is too fine. Frequent clogging may indicate dull burrs or worn delivery mechanism requiring parts replacement.

原因：連續使用時間過長超過額定負荷、馬達散熱風扇故障、進風口被粉塵堵塞、馬達內部線圈輕微短路。商用機型連續研磨建議適度休息；家用機連續磨超過30秒自動停屬正常。若短時間使用就過熱，需檢查散熱系統與馬達狀態，避免馬達燒毀。

Causes: Exceeding duty cycle with continuous use, faulty cooling fan, dust-blocked air intake, slight short circuit in motor windings. Commercial machines should rest periodically; home models auto-stopping after 30+ seconds is normal. If overheating occurs quickly, check cooling system and motor condition to prevent burnout.

常見問題：調節螺紋積粉卡死、彈簧定位珠磨損或脫落、調節齒輪磨損滑牙、內部螺桿變形。切勿強行轉動以免造成螺紋崩牙。可先嘗試清潔調節機構的咖啡粉塵；若仍無法順利調節，需拆解更換定位彈簧或修復螺紋結構。

Common issues: Powder buildup jamming adjustment threads, worn or fallen detent ball, stripped gear teeth, deformed internal screw. Do not force-turn to avoid thread damage. Try cleaning coffee dust from adjustment mechanism first. If still stuck, disassembly is needed to replace detent spring or repair thread structure.

原因包括：計量撥粉葉片磨損、粉倉內粉量不足造成虛位、電子式計時器飄移、微型開關接觸不良。機械式定量機構需定期清潔粉塵並檢查葉片磨損；電子定時型可重新校準時間參數。若長期使用後誤差越來越大，通常是磨損零件需要更換。

Causes: Worn dosing vanes, insufficient powder in hopper causing gaps, electronic timer drift, faulty micro switch. Mechanical dosers need regular cleaning and vane wear inspection. Electronic timed models can be recalibrated. Increasing inaccuracy over time usually indicates worn parts needing replacement.

常見位置：出粉口密封圈老化、機身接合縫隙變大、豆倉底部密封墊磨損、粉杯對位不準。輕微飛粉屬正常現象，尤其細研磨時靜電明顯。若漏粉嚴重影響使用，檢查更換相關密封膠圈，確保各部件安裝到位，部分機型可加裝防飛粉改裝件。

Common locations: Worn chute seal, widened body seams, worn hopper gasket, misaligned portafilter. Slight powder dispersion is normal, especially with fine grinds and static. If severe, inspect and replace sealing rings, ensure proper assembly. Some models accept anti-static modifications.

這是典型的卡滯症狀：異物卡死刀盤、傳動皮帶斷裂或脫落、減速齒輪崩齒、馬達啟動電容故障。請立即關閉電源，切勿長時間通電以免燒毀馬達線圈。先檢查是否有硬物卡住刀盤；如無則可能是傳動系統或啟動電容問題，需專業維修。

Classic jam symptom: Foreign object jamming burrs, broken/dislodged drive belt, stripped gear teeth, faulty start capacitor. Turn off power immediately. Do not keep power on as this can burn motor windings. First check for hard objects jamming burrs. If clear, likely transmission system or capacitor issue requiring professional repair.

這是危險訊號！通常是刀盤嚴重磨損掉屑、刀盤螺絲鬆動造成摩擦、內部金屬部件磨損。請立即停用並清空所有咖啡粉。刀盤是消耗品，長期使用後刀刃會磨耗，嚴重時會產生金屬粉末。需儘快更換全新刀盤組，並檢查刀盤座是否受損。

This is a danger sign! Usually from severely worn burrs shedding particles, loose burr screws causing friction, or internal metal component wear. Stop using immediately and empty all grounds. Burrs are consumable; edges wear over time and can produce metal particles when severe. Replace burr set promptly and check burr carrier for damage.

原因：面板表面有水漬或咖啡漬導電異常、觸控膜老化、內部按鍵板進液氧化、排線接觸不良。先清潔擦乾面板表面測試；若仍失靈，商用機型多為觸控模組故障，家用機可能是按鍵開關磨損。液體滲入造成的故障需盡快處理，避免腐蝕擴大。

Causes: Water or coffee residue causing conductive interference, aged touch film, liquid damage to internal keypad, loose ribbon cable. Clean and dry panel surface first. If still faulty, commercial models often have touch module failure; home models may have worn button switches. Liquid damage should be addressed promptly to prevent corrosion spread.

優先檢查：電源插座是否有電、電源線內部斷線、機器保險絲熔斷、電源板故障。可用其他電器測試插座；檢查機身是否有更換保險絲的位置。若更換保險絲後立即再次燒斷，代表內部有短路，切勿更換大安培保險絲，應送修檢查電源電路。

Check first: Power outlet working, internal power cord breakage, machine fuse blown, power board failure. Test outlet with another appliance. Check if machine has accessible fuse holder. If fuse blows again immediately after replacement, there is an internal short circuit. Do not use higher amp fuse. Send for circuit inspection.
