beko wm5100w wahing machine stats and stops filling continuesly?

ive tried a system reset and also leaving it switched off for a couple of days and resetting it on 90 then putting it on spin. all that happens when i press start on a wash cycle is it begins to fill then stops then starts to fill again and so on. each time it stops filling the ready light comes on then when it starts filling again it goes off. ive fitted new brushes, checked the filter and cleaned it and cleane the pump. help. its driving me mental.
