常(chang)見程序控制系統故障：　

　1.接通電(dian)(dian)源(yuan)電(dian)(dian)動(dong)(dong)機就運轉(zhuan)出現這(zhe)種(zhong)故(gu)(gu)障(zhang)(zhang)的(de)原(yuan)因可(ke)能是(shi)：　　電(dian)(dian)動(dong)(dong)機驅動(dong)(dong)電(dian)(dian)路(lu)(lu)上的(de)雙向(xiang)可(ke)控硅短路(lu)(lu)性損(sun)壞或晶(jing)體(ti)管集(ji)電(dian)(dian)極、發(fa)射極間擊穿,更換損(sun)壞件(jian)(jian)后故(gu)(gu)障(zhang)(zhang)即可(ke)排除(chu)。　　2.洗滌或脫水(shui)運轉(zhuan)沒完(wan)就停止故(gu)(gu)障(zhang)(zhang)原(yuan)因可(ke)能是(shi)：　　水(shui)位開關(guan)或安全(quan)開關(guan)接觸(chu)不(bu)良；負載件(jian)(jian)發(fa)生(sheng)(sheng)故(gu)(gu)障(zhang)(zhang)；接插件(jian)(jian)松動(dong)(dong)或有(you)關(guan)電(dian)(dian)路(lu)(lu)元件(jian)(jian)虛焊.檢(jian)查修理或更換相關(guan)部(bu)件(jian)(jian)即可(ke)。另外(wai)，電(dian)(dian)源(yuan)電(dian)(dian)壓波動(dong)(dong)大也會使(shi)洗衣機運轉(zhuan)突然停止或程(cheng)(cheng)序突然發(fa)生(sheng)(sheng)變(bian)化。　　3.程(cheng)(cheng)序板按鈕(niu)(接觸(chu)開關(guan))失效故(gu)(gu)障(zhang)(zhang)原(yuan)因可(ke)能是(shi)：　　(1)按鈕(niu)本身接觸(chu)不(bu)良。檢(jian)查修復或跟換新件(jian)(jian)。　　(2)程(cheng)(cheng)序按鈕(niu)對應電(dian)(dian)路(lu)(lu)有(you)故(gu)(gu)障(zhang)(zhang)。檢(jian)查電(dian)(dian)腦板。
