關于洗(xi)衣機進水后出現E8的故障排(pai)除方法(fa)

原(yuan)(yuan)因(yin)分析(xi)：維(wei)修人員上門(men)試機(ji)(ji)發(fa)現(xian)(xian)(xian)洗衣機(ji)(ji)進水后(hou)出現(xian)(xian)(xian)E8后(hou)不(bu)工作，根據(ju)故(gu)障(zhang)符號判斷(duan)可能為電(dian)(dian)源電(dian)(dian)壓(ya)(ya)不(bu)正(zheng)常(chang)(chang)，或(huo)是電(dian)(dian)腦(nao)板出現(xian)(xian)(xian)問(wen)題(ti)(ti)，用(yong)萬用(yong)表測(ce)用(yong)戶(hu)(hu)家電(dian)(dian)壓(ya)(ya)在正(zheng)常(chang)(chang)范(fan)圍內無(wu)異常(chang)(chang)，更換電(dian)(dian)腦(nao)板后(hou)仍出現(xian)(xian)(xian)同一現(xian)(xian)(xian)象，但將(jiang)機(ji)(ji)器(qi)拉(la)回維(wei)修部試機(ji)(ji)正(zheng)常(chang)(chang)。根據(ju)此(ci)情(qing)況(kuang)判斷(duan)原(yuan)(yuan)因(yin)應為用(yong)戶(hu)(hu)家電(dian)(dian)源問(wen)題(ti)(ti)，再次上門(men)檢測(ce)，測(ce)得用(yong)戶(hu)(hu)家電(dian)(dian)壓(ya)(ya)在218V-224V之(zhi)間電(dian)(dian)壓(ya)(ya)正(zheng)常(chang)(chang)，但用(yong)電(dian)(dian)流(liu)(liu)表測(ce)用(yong)戶(hu)(hu)家電(dian)(dian)流(liu)(liu)，發(fa)現(xian)(xian)(xian)電(dian)(dian)流(liu)(liu)在1A-4A之(zhi)間波(bo)動很大(da)，因(yin)此(ci)斷(duan)定問(wen)題(ti)(ti)原(yuan)(yuan)因(yin)是電(dian)(dian)流(liu)(liu)不(bu)穩造成。
