Help: refrigerator water line pulsing
Hi. I'm trying to diagnose an issue with my refrigerator. It is a Kitchenaid KBRS20ETSS01. It has a water filter that mounts inside the cabinet near the ceiling of the refrigerator section. The water comes into this filter and then seems to leave via another line down to the inlet valve where it splits to feed the drinking water outlet and icemaker.
The trouble is it will be working fine but after about 12 oz. of drawing drinking water there is a loud pulsing sound and the water flow slows dramatically. The pulsing will continue even if I let it rest a few minutes before starting to fill again but is immediately resolved if I just unseat and then reseat the water filter.
I originally thought it was probably the inlet valve (and that might still be right but am looking for your wisdom here), but when I pulled out the fridge from the wall, as best I can tell, the pulsing can only be felt in the line coming from the floor into the filter, not in the part from the filter to the valve.
I have tried replacing the filter with a new filter and the problem is the same. Any ideas?
