99.WPM Welhome咖啡機20項常見故障與專業保養｜切勿自行拆解
99. 20 Common WPM Welhome Machine Faults & Maintenance | Self Disassembly Not Allowed
1. WPM Welhome咖啡機不出熱水、無蒸汽功能
故障原因：鍋爐加熱管燒毀、溫度感測器損壞、熱保護跳掣；保養建議：每3個月除水垢，避免長時間空燒。
2. 萃取咖啡出水細、流速極慢
故障原因：分水網堵塞、沖煮頭水垢嚴重、泵浦壓力不足；保養：每次使用後沖洗沖煮頭，每周拆洗分水網。
3. 機身底部漏水、蒸氣桿滴水
故障：密封圈老化、鍋爐接頭膠圈破裂、排水盤膠墊損耗；禁止自行拆水管，易高溫噴水燙傷。
4. 泵浦運作噪音極大、震動劇烈
泵浦內部磨損、減震墊老化、進水濾芯堵塞；保養每月清洗進水過濾器。
5. 無法產生蒸氣、打奶泡無壓力
蒸氣閥堵塞、二次鍋爐故障、蒸氣管道水垢封死；每年一次深度拆解除垢保養。
6. 開機立即跳電、漏電保護觸發
加熱管滲水短路、電線老化破皮、主板受潮；強烈不建議自行開機殼檢查，有觸電風險。
7. 咖啡味道酸澀、帶金屬異味
鍋爐厚水垢、沖煮頭殘留陳舊咖啡油脂；保養每2個月做一次藥劑除油除垢。
8. 開機燈不亮、完全無法啟動
電源開關損壞、保險絲熔斷、主板供電模塊故障。
9. 沖煮頭滴水、關機後持續滲水
萃取閥密封墊磨損，需更換食品級耐高溫膠圈。
10. 水箱水位偵測失靈，缺水警示亂跳
水位浮球卡垢、感應電極氧化；定期拆洗水箱內浮動組件。
11. 蒸氣桿噴水、奶泡混大量熱水
蒸氣閥芯磨損，管道積垢導致水蒸氣分離失效。
12. 機體外殼發燙、溫度異常過高
隔熱棉老化脫落、溫控器失準；長期高溫會加速內部零件老化。
13. 萃取壓力不穩定，時高時低
泵浦壓力調節閥故障、進水壓力不足、管道積氣。
14. 把手無法鎖緊、沖煮頭卡位滑牙
沖煮頭螺紋磨損、把手膠墊變形；硬轉會導致沖煮頭斷裂。
15. 機器內部出現異味、燒焦塑膠味
電線高溫熔化、主板電容燒毀，立即斷電停用，勿繼續開機。
16. 排水盤滿水警示不會彈出，溢水浸泡機器
排水盤感應彈片氧化、卡咖啡渣無法觸發開關。
17. 除垢後機器完全不出水、管道堵死
大塊水垢脫落堵塞細管，需專業師傅拆解疏通管路。
18. 長期閒置開機後泵浦卡死不運轉
泵浦軸心水垢銹蝕，強制開機會燒毀驅動主板。
19. WPM Welhome保養禁忌：自行拆解鍋爐風險
鍋爐儲存高溫高壓熱水，私自拆裝易噴濺燙傷；內部高壓電路有觸電危險，零件規格特殊，非原廠配件易二次損壞。
20. WPM Welhome延長使用壽命完整保養週期
每日：沖洗沖煮頭、擦淨蒸氣桿；每周：拆洗分水網、濾網；每月：清洗水箱濾芯；每季：藥劑除垢；每年：門店深度拆解全機保養。
1. No hot water / No steam function
Fault: Burnt heating tube, broken temperature sensor, thermal cutout. Maintenance: Descaling every 3 months, avoid dry boil.
2. Very slow espresso flow
Blocked shower screen, heavy limescale on group head, weak pump pressure. Clean shower screen weekly.
3. Water leaking from base / steam wand drip
Aged rubber seal, cracked boiler joint gasket. DIY pipe disassembly causes hot water scald risk.
4. Loud pump noise & heavy vibration
Worn pump, damaged shock pad, blocked inlet filter. Clean inlet filter monthly.
5. No steam pressure for milk frothing
Clogged steam valve, secondary boiler failure. Full deep service once per year.
6. Trips electricity safety cut-out immediately
Short circuit from leaking heater tube, aged wiring, damp mainboard. Do NOT open casing yourself, electric shock hazard.
7. Sour / metallic coffee taste
Thick limescale inside boiler, old coffee grease residue. Descaling & backflush every 2 months.
8. No power light, machine dead
Broken power switch, blown fuse, faulty main power module.
9. Constant dripping group head after power off
Worn extraction valve gasket, replace food-grade high temp seal.
10. Water level sensor malfunction, false low water alert
Scale stuck float ball, oxidized electrode. Disassemble & clean water tank regularly.
11. Steam wand sprays hot water into milk
Worn steam valve core, limescale separates steam & hot water.
12. Excessively hot machine body
Fallen heat insulation cotton, faulty thermostat, accelerates internal part aging.
13. Unstable extraction pressure
Faulty pump regulator valve, air trapped in pipe, unstable mains water supply.
14. Portafilter cannot lock, stripped group thread
Worn group head thread, deformed portafilter gasket. Forced twisting cracks group head.
15. Burnt plastic smell inside machine
Melting wiring, burnt mainboard capacitor. Unplug & stop using immediately.
16. Drip tray full sensor fails, water overflow
Oxidized sensor spring stuck with coffee grounds.
17. No water flow after descaling, fully blocked pipes
Large limescale chunks block thin tubes, professional disassembly flushing required.
18. Pump stuck after long idle storage
Rusted pump shaft covered in scale, forced power-on burns mainboard.
19. Danger of DIY boiler disassembly (WPM Welhome Warning)
Boiler holds high temperature & pressure hot water, risk of severe scalding; live high voltage circuits inside, non-original parts cause secondary damage.
20. Full WPM Welhome maintenance cycle to extend lifespan
Daily: Rinse group head & steam wand; Weekly: Clean shower screen; Monthly: Tank filter cleaning; Quarterly: Chemical descaling; Annually: Full machine deep service at Kwun Tong workshop.
