Samsung Fridge Not Dispensing Water or Flowing Slowly? Filter Case Assembly DA97-21797D – Fix Water Flow Fast

No water from your Samsung refrigerator dispenser is almost always traced back to a failed or cracked filter case assembly. In most Samsung French door refrigerators, the filter case assembly (DA97-21797D) houses the water filter and routes pressurized water through the dispenser and ice maker system. When the housing cracks, warps, or the locking mechanism fails, water flow stops entirely, drops to a trickle, or leaks inside the refrigerator compartment. ⚡ Common failure point in Samsung refrigerators with internal filter systems. Part DA97-21797D is the genuine OEM replacement that restores full water pressure, eliminates internal leaks, and gets your dispenser and ice maker running normally again.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Refrigerator powers on and cools normally
• ✔ Water supply line to the fridge is connected and valve is open
• ✔ Water filter has been recently replaced or confirmed not clogged
• ✔ ONLY problem is no water or slow flow from the dispenser, water leaking inside the fridge near the filter, or the filter not seating/locking properly in the housing

🔧 Common Symptoms

• No water dispensing from the door dispenser despite a fresh filter installed
• Very slow or reduced water flow from the dispenser or ice maker
• Water leaking inside the refrigerator near the filter housing area
• Filter will not lock, seat, or click into place in the housing
• Water filter indicator light stays on after filter replacement

Remove the existing filter and housing assembly from the refrigerator compartment, disconnect the water line fittings, transfer any retaining clips or brackets to the new housing, reconnect the water lines, and install a fresh filter. Restore water supply and power, then run 2–3 gallons of water through the dispenser to flush the new system before use.
