二、WPM Welhome咖啡機專業保養知識

3. 每3個月更換沖煮頭膠圈、水箱密封圈，預防漏水
3. Replace gaskets every 3 months to avoid leakage
4. 僅使用過濾軟水，自來水礦物質易產生水垢
4. Only use filtered soft water to reduce scale
5. 閒置3天以上排空鍋爐殘水，避免管路發霉
5. Empty boiler water if idle over 3 days to prevent mould
6. 每周刷洗粉碗濾網，細孔堵塞影響萃取壓力
6. Clean filter basket weekly for stable extraction pressure
