Understanding the Problem
Brief explanation: The Whirlpool part 4396508 (sold under EveryDrop as EDR5RXD1 and as multi-pack 4396508P) is an in-line refrigerator water/ice filter cartridge that reduces chlorine taste/odor, sediment, and other common contaminants. When it clogs or reaches end-of-life it causes poor-tasting water, cloudy or bad-smelling ice, slow dispensing, and sometimes dispenser error messages. Step-by-step diagnostic and repair instructions: 1) Confirm the symptom: note whether the issue is taste/odor, slow flow, cloudy ice, or a visible leak. Check the filter change date — most filters are due around every 6 months. 2) Check water flow with the filter removed: locate and remove the filter (see replacement steps below). Place a container under the dispenser and run the water with the filter removed or bypassed. If flow improves markedly when the filter is removed, the filter is clogged and should be replaced. 3) Inspect the housing and O-ring: with the filter removed, inspect the housing seat and O-ring for cracks, debris, or a torn/dried O-ring — damage here can cause leaks or air entering the system (air causes sputtering water/ice issues). 4) Replace the filter: install a new genuine 4396508 / EveryDrop EDR5RXD1 cartridge. Make sure the filter is fully seated and turned/locked per model instructions until it clicks. 5) Flush the filter: after installation, dispense and discard roughly 2–3 liters (about 2–3 quarts) of water to flush carbon fines and air from the new cartridge. If your fridge makes ice, also discard the first few batches of ice for best taste. 6) Reset the filter indicator: on many Whirlpool refrigerators hold the 'Filter Reset' or 'Ice/Water' button for 3–5 seconds. Consult your model manual if unsure. 7) Test for leaks and performance: check around the filter housing for drips while dispensing. Verify improved taste and flow. How to fix common issues: - Slow flow but no leaks: replace the filter; clogged filter is most likely. If new filter still slow, check household water pressure and inlet valve. - Bad taste/odor or cloudy ice: replace filter and flush thoroughly; discard several batches of ice after replacement. - Leaks after replacement: remove the filter, inspect/clean the O-ring and filter seat, then reinstall ensuring proper alignment and full rotation until engaged. Replace cracked O-ring or housing if needed. Safety note: Turn off the water supply only if you will be working on the water line or if the filter housing leaks heavily. Otherwise, most filter swaps are done with the refrigerator powered and water on. Always wipe up spills promptly and avoid using excessive force when installing the cartridge.

Helpful Repair Tip
To confirm the filter is the problem, remove it and run the dispenser: if flow and taste improve immediately, the filter was clogged. If flow is still poor with the filter removed, check the household water line, shutoff valve, and inlet valve.
Frequently Asked Questions
How often should I replace the 4396508 water filter?
Replace every 6 months or sooner if you notice reduced flow, bad taste/odor, or cloudy ice. Replace earlier if your household water has heavy sediment or high usage (large families).
Can I use my refrigerator without the 4396508 installed?
Yes — the fridge will generally dispense water without the filter installed (depending on model), but water will be unfiltered and may taste or smell different. Some models require a bypass adapter; others will allow the filter to be removed. Running without a filter is not recommended long-term and may affect ice taste.
