常見程序控制系(xi)統故障(zhang)：　

　1.接(jie)(jie)(jie)通電(dian)(dian)源電(dian)(dian)動機(ji)就(jiu)運(yun)轉出(chu)現這種(zhong)故障(zhang)(zhang)的(de)原因(yin)可(ke)能是(shi)：　　電(dian)(dian)動機(ji)驅動電(dian)(dian)路(lu)(lu)上的(de)雙向(xiang)可(ke)控硅短路(lu)(lu)性損壞(huai)或晶體管集電(dian)(dian)極、發射極間擊穿,更換(huan)損壞(huai)件(jian)(jian)(jian)(jian)后故障(zhang)(zhang)即可(ke)排除(chu)。　　2.洗滌或脫(tuo)水(shui)運(yun)轉沒完就(jiu)停(ting)止故障(zhang)(zhang)原因(yin)可(ke)能是(shi)：　　水(shui)位開(kai)關(guan)(guan)或安全開(kai)關(guan)(guan)接(jie)(jie)(jie)觸(chu)不良(liang)；負載(zai)件(jian)(jian)(jian)(jian)發生故障(zhang)(zhang)；接(jie)(jie)(jie)插件(jian)(jian)(jian)(jian)松動或有關(guan)(guan)電(dian)(dian)路(lu)(lu)元件(jian)(jian)(jian)(jian)虛焊.檢查(cha)修(xiu)理(li)或更換(huan)相關(guan)(guan)部件(jian)(jian)(jian)(jian)即可(ke)。另外，電(dian)(dian)源電(dian)(dian)壓波(bo)動大也會使洗衣(yi)機(ji)運(yun)轉突(tu)然停(ting)止或程序突(tu)然發生變(bian)化。　　3.程序板(ban)按鈕(niu)(接(jie)(jie)(jie)觸(chu)開(kai)關(guan)(guan))失效故障(zhang)(zhang)原因(yin)可(ke)能是(shi)：　　(1)按鈕(niu)本身接(jie)(jie)(jie)觸(chu)不良(liang)。檢查(cha)修(xiu)復或跟換(huan)新件(jian)(jian)(jian)(jian)。　　(2)程序按鈕(niu)對應電(dian)(dian)路(lu)(lu)有故障(zhang)(zhang)。檢查(cha)電(dian)(dian)腦板(ban)。
