Whirlpool EDR1RXD1 Refrigerator Water Filter: Step-by-Step Installation Guide

Place a towel underneath

Put a small towel or cloth directly below the filter housing to catch any water that drips during removal. This is normal and expected.

Push in, then turn counterclockwise

Grip the filter firmly. Push it inward slightly (toward the back of the fridge), then rotate it counterclockwise about a quarter turn (approximately 90°). You’ll feel it release from the locked position.

Pull the filter straight out

Once unlocked, pull the filter straight toward you. Some water will drip — this is normal. Set the old filter aside.

Remove the protective cap

Your new EDR1RXD1 comes with a protective plastic cap on the filter end. Remove and discard it before installation.

Transfer the end cap (if required)

Some Whirlpool refrigerator models require you to move the blue end cap from the old filter to the new one. Check your old filter — if it has a blue cap on the back end, twist it off and attach it to the new filter before installing.

Check the O-ring

Inspect the rubber O-ring on the filter end. It should be smooth, round, and undamaged. A damaged O-ring will cause leaks. Genuine EDR1RXD1 filters always include a properly fitted O-ring.

Align the filter with the housing

Hold the new filter with the label facing outward. Align the filter’s tabs or notches with the slots in the housing. There is usually an arrow or alignment mark on the filter to guide you.

Push in and turn clockwise

Push the filter firmly into the housing, then rotate it clockwise about a quarter turn (approximately 90°) until it locks. This is the reverse of the removal motion.

Confirm it’s locked

The filter should feel firm and secure with no wobble. On many models, you’ll hear or feel a subtle click when it’s fully seated. Gently tug the filter — it should not pull out without the push-and-turn motion.

Dispense 2–3 gallons of water

Hold a large container under the dispenser and run water continuously for approximately 5 minutes. This purges carbon fines, air pockets, and any manufacturing residue from the new filter.

Expect sputtering and cloudiness

During flushing, water may sputter, appear cloudy or milky, or have a slight grey tint. This is completely normal — it’s just air and carbon fines clearing out. It will clear within the first gallon.

Discard the flush water

Don’t drink the flush water. Use it to water plants, clean, or simply pour it down the drain. After flushing, your water is ready to drink.

Discard the first 2 batches of ice

If your fridge has an ice maker, discard the first 2–3 batches of ice produced after the filter change. Old water sitting in the ice maker lines will produce off-tasting ice until it’s flushed through.

Most Whirlpool / Maytag / KitchenAid models (2015–present)

Press and hold the “Filter Reset” or “Water Filter” button on the control panel for 3–5 seconds until the indicator light turns green or blue.

Some models with dual-button reset

Press and hold “Options” + “Water Filter” simultaneously for 3 seconds.

Older Whirlpool models (pre-2015)

Press and hold “Light” + “Ice Type” for 3 seconds, or check your owner’s manual for the specific reset sequence.

Amana models

Press and hold the “Filter Reset” button for 3 seconds. The light will turn off or change to green.

Skipping the flush

The #1 mistake. Always flush 2–3 gallons before drinking. Skipping this causes bad taste and cloudy water that people mistakenly blame on the filter.

Forgetting to reset the filter light

The light won’t reset itself. Always manually reset it after installation so your 6-month timer starts fresh.

Not transferring the end cap

On models that require it, forgetting to move the blue end cap from the old filter to the new one will prevent proper installation and cause leaks.

Overtightening the filter

Only a quarter turn is needed. Forcing the filter further can crack the housing or damage the O-ring, causing leaks.

Installing the wrong filter

The EDR1RXD1 and EDR4RXD1 look similar but are not interchangeable. Always verify your model number before purchasing. See our compatibility list.

Buying a counterfeit filter

Fake EDR1RXD1 filters are common online. They may not fit properly, may not filter contaminants, and can void your fridge warranty. Always buy from authorized retailers.
