Haing problems with washing machine rinse and drain cycle not working, doesnt seem to be any water to rinse although there is water for washing, it doesnt do a full wash there is a beep everytime u need to rinse and spin, can u give me any adivce, i have tried the front filter nothing seems to be wrong and there is a small hose beside the filter the i have taken the plastic cap off of that to drain water from that, basically is it worth getting fixed or replaced? thanks
