Find Your Whirlpool Filter Model and Location

The first step is identifying which Whirlpool appliance needs a filter and where that filter sits. Whirlpool makes refrigerators, washing machines, and dishwashers — each uses a different filter type and sits in a different spot. Open your appliance manual or look inside the unit itself for a label showing the model number.

For refrigerators, the water filter is almost always in the upper right corner of the fridge compartment or in the base grille at the bottom front. For washing machines, the inlet filter screens are behind the hose connections at the back of the unit. Dishwashers have a fine mesh filter at the bottom of the tub. Write down your exact model number before you order a replacement — Whirlpool filters are model-specific and the wrong one will not fit.

Key Takeaways

  • Whirlpool filters vary by appliance type: refrigerator filters sit in the fridge or base grille, washing machine filters are behind the hoses, and dishwasher filters are at the bottom of the tub.
  • Order the correct replacement by matching your appliance model number to the filter part number in your manual or on the Whirlpool website.
  • Most refrigerator and washing machine filters take under five minutes to swap out with no tools required.
  • Dishwasher filters need a rinse under running water every month and a full replacement once a year, depending on water hardness.
  • Keep your old filter box or note the part number so you can reorder the exact same filter when it needs replacing again.

Order the Correct Replacement Filter

Whirlpool sells filters under several part numbers depending on your appliance model. The most common refrigerator filter is the 4396508 or 4396510, but your model may use a different one. Check your appliance manual first — it lists the exact part number on the specifications page or inside the back cover.

If you do not have the manual, visit the Whirlpool website, enter your model number in the parts search, and select "filters" from the category list. You can also call Whirlpool customer service at 1-866-664-6001 with your model number and they will tell you which filter you need. Order from Whirlpool directly, from a major retailer like Best Buy or Lowe's, or from online sellers — prices vary, so compare before you buy. Genuine Whirlpool filters cost between $30 and $60 depending on the type.

Replace a Refrigerator Water Filter

Turn off the water supply to your refrigerator before you start. Look for the shut-off valve behind the fridge where the water line connects — turn it clockwise until it stops. If you cannot find a valve, turn off the main water supply to your house.

Locate the filter cartridge. In most Whirlpool refrigerators, it is in the upper right corner of the fridge compartment behind a plastic cover, or in the base grille at the bottom front. Press the release button or twist the cover counterclockwise to open it. Pull the old filter straight out — water may drip, so have a towel ready. Insert the new filter with the arrow pointing toward the fridge, then twist or snap the cover closed. Turn the water supply back on and let water run through the filter for 30 seconds before using it.

Replace Washing Machine Inlet Filters

Washing machine filters are small screens that catch debris in the water lines. You do not need to turn off the water for this job. Locate the inlet hoses at the back of the machine — there are usually two, one for hot water and one for cold. Unscrew the hose from the back of the machine by turning it counterclockwise by hand.

Inside the connection point, you will see a small mesh screen. Use needle-nose pliers to gently pull it straight out. Rinse the old screen under running water to see if it is clogged with sediment — if it is, replace it. If it is clean, you can reuse it. Insert the new screen with the flat side facing out, then screw the hose back on hand-tight. Do the same for the second hose. Run a test cycle to make sure water flows normally.

Clean or Replace a Dishwasher Filter

Dishwasher filters do not need replacement as often as refrigerator filters, but they do need regular cleaning. At the bottom of the tub, you will find a cylindrical or basket-shaped filter. Remove it by twisting counterclockwise or lifting straight up — check your manual for the exact motion. Rinse it under hot running water and use a soft brush to remove food particles and mineral buildup.

If the filter is cracked, has holes, or does not rinse clean, order a replacement using your model number. Installation is the reverse of removal — insert the new filter and twist or push it down until it locks in place. Run a short cycle to confirm the filter seated correctly and water drains properly.

When to Replace Each Filter Type

Refrigerator water filters should be replaced every six months if you use the ice maker or water dispenser regularly, or every 12 months if you use them occasionally. If your water tastes off or the dispenser slows down, the filter is clogged and needs replacing sooner. Washing machine inlet filters do not have a set replacement schedule — inspect them once a year and replace them only if they are visibly clogged with sediment or rust.

Dishwasher filters need cleaning every month and replacement once a year, though this varies based on your water hardness and how often you run the machine. If you have very hard water, you may need to replace it every six months. Keep track of when you last replaced each filter by writing the date on the new filter box with a permanent marker before you install it.

Troubleshooting Common Filter Problems

If water still tastes bad after you replace the refrigerator filter, the filter may not be seated correctly. Remove it and reinstall it, making sure you hear or feel it click into place. If the water dispenser is slow, the new filter may be clogged already — this happens if sediment in your water line is heavy. Run water through the dispenser for one full minute to flush the line, then try again.

If your washing machine does not fill with water after you replace the inlet filters, you may have installed them backward. The flat side should face outward toward the hose connection. Remove the hose, check the filter direction, and reinstall it. If the dishwasher still has standing water at the bottom after you clean the filter, the drain line may be blocked separately — that is a different repair and your manual will show you how to access it.

Frequently Asked Questions

Can I use a generic filter instead of a Whirlpool brand filter?

Generic filters may fit and work, but Whirlpool filters are engineered for your specific model and water pressure. Using a non-Whirlpool filter can void your warranty and may not filter as effectively. Stick with the part number in your manual.

What do I do with the old filter?

Most old filters can go in the trash. Some retailers like Best Buy accept used filters for recycling — call ahead to confirm. Do not pour the old filter down the drain or compost it.

How much water should I run through a new refrigerator filter before drinking it?

Run water through the dispenser for 30 seconds to one minute before you drink it. This flushes out any carbon dust or manufacturing residue inside the new filter. After that, the water is safe to drink.

Do I need tools to replace a Whirlpool filter?

Refrigerator and dishwasher filters need no tools — they twist or snap by hand. Washing machine inlet filters may need needle-nose pliers to remove the old screen, but most people can do it with their fingers if the screen is not stuck.

Why is my new filter leaking?

The filter is not seated all the way in. Remove it, check that the rubber gasket is clean and not twisted, and push or twist it back in until you feel it lock. If it still leaks, the gasket may be damaged — contact Whirlpool for a replacement.
