side by side samsung water dispenser continues to shoot water

I have a Samsung rsg257aars side by side water dispenser will not stop dispensing. I heard that filter not sealing can cause this. I replaced the filter and it work fine for a few days then started again. I also tried a Samsung brand filter ($50 from Lowes) still no luck. I am thinking about replacing the filter housing next but I wanted to check here before shelling out another $70. It does the same thing without a filter.

More info. The ice dispenser works fine so that ruled out the microswitch. I even tested the microswitch separately with a meter. works perfect,

I look forward to hearing from some more experienced folks out there
