My Servis M6115 is filling,and tumbling clockwise,but nothing further. I observed that the drum does not rotate anti-clockwise just sits there and timer clicks,then it rotates clockwise again. But it does not progress into taking in rinse water and softener-it just stops!! If I put it on other programmes it will spin but not rinse. Can anyone suggest source of problem and a cure please?
