I have a Bosch side by side model Bosch B22CS50SNS/01.

When we go to fill a glass of water from the dispenser on the front the first ounce of two flows nicely but then the flow slows to a trickle and a hammering sound comes from the area of the filter. I replaced the water inlet valve at the bottom of the fridge as well as the filter and all worked well for a couple of days, then it started again and has been making the noise ever since.

I wonder if this could be a voltage problem with the control board that is opening the water inlet valve. I don't know where the control board is, and also, what voltage or how the valve is regulated. Thoughts?

Thanks
