Washer works find until it get to rinse cycle and then it will not fill and finish cycle.
You will want to check the cold water supply to make sure that the water valve is not clogged up. If the screen on the valve is clogged and will not allow the unit to bring cold water into the unit then it will not advance past the rinse cycle. If this checks ok then check to make sure that the water valve is getting 120 vac to it. If the valve is getting 120 vac to it but no water is coming in then the water valve is faulty and needs to be replaced.
