Samsung refrigerator water dispenser is not working after I changed the water filter. I have an older Samsung refrigerator. The water stopped coming out. I changed the filter and nothing happened. I stuck a wire up the water line thinking it was frozen and it seemed fine so I tried it again and still no water. About an hour later it was working again. I woke up this morning and it wasn't working again so I did the same thing and about an hr later it was working again.
