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

榮事達洗衣(yi)機(ji)維修服務中心關于洗衣(yi)機(ji)進水后出現E8的故障(zhang)排除方法(fa)

原因(yin)分析：維修(xiu)人員上(shang)門(men)試機發現洗衣機進水(shui)后出現E8后不(bu)工作，根據(ju)故(gu)障符(fu)號判(pan)斷可能為電(dian)(dian)(dian)源電(dian)(dian)(dian)壓(ya)不(bu)正(zheng)常(chang)，或是電(dian)(dian)(dian)腦板出現問(wen)題(ti)，用(yong)(yong)(yong)萬用(yong)(yong)(yong)表測(ce)(ce)用(yong)(yong)(yong)戶(hu)家電(dian)(dian)(dian)壓(ya)在(zai)正(zheng)常(chang)范圍內無(wu)異(yi)常(chang)，更換電(dian)(dian)(dian)腦板后仍出現同一現象，但(dan)(dan)將(jiang)機器拉回(hui)維修(xiu)部試機正(zheng)常(chang)。根據(ju)此(ci)情(qing)況判(pan)斷原因(yin)應為用(yong)(yong)(yong)戶(hu)家電(dian)(dian)(dian)源問(wen)題(ti)，再次上(shang)門(men)檢(jian)測(ce)(ce)，測(ce)(ce)得用(yong)(yong)(yong)戶(hu)家電(dian)(dian)(dian)壓(ya)在(zai)218V-224V之(zhi)間電(dian)(dian)(dian)壓(ya)正(zheng)常(chang)，但(dan)(dan)用(yong)(yong)(yong)電(dian)(dian)(dian)流(liu)表測(ce)(ce)用(yong)(yong)(yong)戶(hu)家電(dian)(dian)(dian)流(liu)，發現電(dian)(dian)(dian)流(liu)在(zai)1A-4A之(zhi)間波動(dong)很大，因(yin)此(ci)斷定(ding)問(wen)題(ti)原因(yin)是電(dian)(dian)(dian)流(liu)不(bu)穩(wen)造成(cheng)。
