If your on well water it most likely is sediment from the well and you'll need to change the filter and fluseh the line.

Sometimes sediment in the pipes, or at a fitting, can dislodge and work its way through. If you can access the water filter, remove it, put a catch basin under and teat at that location. Try emptying the filter (through a strainer) while shaking.

If the fridge is still under warranty I would highly reccommend that you contact the company!
