榮事達洗衣機維修服務中心關于洗衣機進水后出現E8的故障排除方法

榮事達(da)洗衣機維修服務(wu)中心關于(yu)洗衣機進水后出現E8的故(gu)障排除(chu)方法








原因分析:維(wei)修(xiu)人(ren)員上門(men)試機(ji)(ji)(ji)發現洗衣機(ji)(ji)(ji)進水后(hou)出現E8后(hou)不(bu)工作,根據(ju)故障符號(hao)判斷(duan)可能(neng)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不(bu)正(zheng)(zheng)(zheng)常(chang),或是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦板出現問(wen)(wen)題(ti),用(yong)萬用(yong)表測(ce)用(yong)戶(hu)家(jia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)正(zheng)(zheng)(zheng)常(chang)范圍(wei)內(nei)無異常(chang),更換電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦板后(hou)仍出現同一現象(xiang),但(dan)將(jiang)機(ji)(ji)(ji)器拉回(hui)維(wei)修(xiu)部試機(ji)(ji)(ji)正(zheng)(zheng)(zheng)常(chang)。根據(ju)此情(qing)況判斷(duan)原因應為用(yong)戶(hu)家(jia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源問(wen)(wen)題(ti),再次(ci)上門(men)檢測(ce),測(ce)得用(yong)戶(hu)家(jia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)218V-224V之間電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)正(zheng)(zheng)(zheng)常(chang),但(dan)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)表測(ce)用(yong)戶(hu)家(jia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu),發現電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在(zai)1A-4A之間波動很大,因此斷(duan)定問(wen)(wen)題(ti)原因是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)不(bu)穩造成。

維修(xiu)措施:向用戶(hu)咨詢(xun)、解答,指導用戶(hu)待(dai)電流正常(chang)后再(zai)使用。
