Tools
- None (a towel for drips)
Parts
- Filter matching your model’s filter number (printed on the old filter)
Step by step
-
1 Find the filter
Inside the fridge ceiling or between the crispers on french doors, in the base grille on older models, or in the upper right corner. The old filter’s label shows the replacement number.
-
2 Release the old filter
Quarter twist counterclockwise and pull, or push button release depending on style. A tablespoon of water escaping is normal.
-
3 Seat the new one
Remove the caps, push in, and quarter twist until it locks/clicks. No tools, no force, if it fights, it’s misaligned.
-
4 Flush and reset
Run 2 to 4 gallons through the dispenser to purge air and carbon fines (sputtering is normal at first), then hold the filter reset button until the indicator changes.
-
5 Repeat every 6 months
An overdue filter chokes flow and shrinks ice cubes, it’s the cheapest fix on the whole water system.
Whirlpool WRS588FIHZ notes & error codes
In Door Ice models live and die by the ice compartment seal. If the customer reports frost building on the ice bucket or a fan noise from the door, check the seal before condemning the ice maker itself, replacing the maker alone on a leaking compartment just repeats the failure in six months.
| Code | What it means |
|---|---|
| Diagnostic mode | Press and hold the door switch sequence, this platform reports faults through the display, not stored codes |
| 6 flashes | Evaporator fan circuit fault |
| Ice maker off icon | Ice maker disabled or the compartment thermistor is out of range |

If flow is still weak with a brand new filter, the inlet valve or a frozen door line is the real cause, see those guides, or have a pro test the water path end to end. If you'd rather skip it entirely, find a refrigerator repair pro near you
