洗衣機進水后出現E8的故障排除方法

洗衣機(ji)進水后出現E8的故(gu)障排除方法(fa)

原(yuan)因分析(xi)：維修人員上(shang)門試機(ji)發現(xian)洗衣(yi)機(ji)進水后(hou)出(chu)現(xian)E8后(hou)不(bu)工作，根(gen)據故障符號(hao)判(pan)斷可能為電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)不(bu)正常(chang)(chang)，或是電(dian)(dian)腦板出(chu)現(xian)問(wen)題(ti)，用(yong)萬用(yong)表測用(yong)戶(hu)家電(dian)(dian)壓(ya)在(zai)正常(chang)(chang)范圍內(nei)無異常(chang)(chang)，更換電(dian)(dian)腦板后(hou)仍出(chu)現(xian)同一現(xian)象，但(dan)將機(ji)器拉回(hui)維修部試機(ji)正常(chang)(chang)。根(gen)據此情況判(pan)斷原(yuan)因應為用(yong)戶(hu)家電(dian)(dian)源(yuan)問(wen)題(ti)，再次上(shang)門檢測，測得用(yong)戶(hu)家電(dian)(dian)壓(ya)在(zai)218V-224V之(zhi)間電(dian)(dian)壓(ya)正常(chang)(chang)，但(dan)用(yong)電(dian)(dian)流表測用(yong)戶(hu)家電(dian)(dian)流，發現(xian)電(dian)(dian)流在(zai)1A-4A之(zhi)間波(bo)動很大，因此斷定問(wen)題(ti)原(yuan)因是電(dian)(dian)流不(bu)穩造(zao)成。

維修措施：向(xiang)用戶咨(zi)詢、解(jie)答，指導用戶待電流(liu)正常后(hou)再(zai)使用。
