Decided to post this to all the samsung filters I've bought in the past. Took me 6months to fix my issue. Replacement part: Samsung DA97-08006D to fix the water filter head. The valves inside gets damaged by 3rd party filters. Symptoms: after switching out of a 3rd party water filter, I had intermittent slow flow, and I hear a hammering struggling sound from back of the fridge. I swap into a genuine filter and it did not resolve it because the valve is already broken. Diagnosis: Water filter head broken. There's two valves that are in the water filter head assembly. They look like a Phillips head. When using non-samsung genuine filters, these valves can be damaged and causes poor flow through the filter and resulting in low pressure for dispenser. To check, remove the water filter and try to dispense water. If it can provide strong pressure and no noise, this is your problem. Other poss diagnosis: Frozen water line above the freezer. This is slow flow or no flow whatsoever even if water filter is removed. To fix this, you can either thaw your fridge or syringe squirt some warm water into this hose. It's pretty long. There's a product you can buy for this but it's just some simple tubing with a syringe. Water inlet valve broken - all water to the machine would be decreased. So your ice maker and water dispenser would not be working. Water inlet valve is at the back of the fridge most of the time. Water dispenser trigger broken - when you depress the trigger, there's not even any sound like water trying to come out or any motor sound or diff humming sound. Requires taking apart the water dispenser at the front and replace the trigger. Solution: buy this water filter head only. Check with Samsung parts dot come to make sure it matches your fridge. This one replaced my RF28HMEDBSR/AA model. Original water filter head part number DA61-05525A. There's a video on YouTube that shows you how to take the whole assembly out and there's one particular video that shows you how to open up the housing. I did this all inside the fridge and only sprayed about 3L of water everywhere because I didn't shut off my water. As someone else commented. I only replaced the head piece using original tubing. The white tubing is the water from the house. Blue is going to the reservoir and then to your water dispenser. I had to do this 3x because I kept forgetting to put the red clip back on, or put the water filter tray back on, or a screw back on. Note, there's actually 3 clips on the underside of the housing which I couldn't reach the back one and broke the clip. Oh well. So from here on out, I'll never use 3rd party filters. The fix was only 65 dollars but it took a lot of research and the courage to open up the fridge to fix. DA97-8006D
