### 1. The Water Filter: The Most Likely Culprit
The most frequent cause of off-tasting water is a water filter that has reached the end of its life. The filter's job is to remove contaminants like chlorine, lead, and pesticides that can affect taste and odor . Over time, it becomes clogged and can no longer effectively do its job, or it can even start to leach trapped particles back into the water.
- **Replace Every Six Months:** Whirlpool recommends replacing your water filter **at least every six months** or when the replacement indicator light on your dispenser turns on . Depending on your water quality and usage, you may need to change it more frequently .
- **Follow Correct Replacement Procedure:** The exact steps depend on your refrigerator model. The filter is typically located in the upper right-hand corner of the refrigerator interior, in the base grille, or on the left side of the base grille . Always use a genuine Whirlpool or everydrop® filter to ensure proper fit and performance . Be sure to remove the protective coverings from the O-rings on the new filter before installing it to ensure a proper seal .
- **Flush the New Filter Properly:** This is a critical, and often overlooked, step. After installing a new filter, you must flush the system to remove excess carbon dust and air from the new filter. This requires dispensing a significant amount of water—typically **4 gallons (about 15 liters)** —through the dispenser. Discard all this water . If you don't have a dispenser, fill and discard three full ice containers . If the water appears cloudy right after a filter change, this is normal and should clear up after flushing .
### 2. Evaluate Your Water Source and Plumbing
The taste of the water coming into your refrigerator is just as important as the filtration system.
- **Softened Water:** It is **strongly recommended to avoid connecting your refrigerator to a softened water source**. The salt and chemicals from a water softener can damage internal components and impart a salty or chemical taste to your water and ice . If this is unavoidable, ensure your softener is very well-maintained.
- **New Plumbing:** If you have recently had new plumbing installed, the taste could be coming from the pipes themselves. Flush a significant amount of water through the dispenser and discard the first few batches of ice .
- **Supply Line Type:** Whirlpool recommends using a copper water supply line or a specific installation kit. Using an incorrect or low-quality plastic line can sometimes affect taste. Also, verify that the refrigerator is connected to the **cold water line**, as hot water can cause discoloration and odd flavors .
- **Check for Kinks:** Ensure the water supply line is not kinked or pinched behind the refrigerator, as this can restrict water flow, and though it is more related to pressure, it can be a factor in the water's overall quality .
### 3. Eliminating Odors from Inside the Refrigerator
A very common and surprising cause of bad-tasting water and ice is the air inside your refrigerator. Air circulates between the fresh food and freezer sections, meaning potent odors from one area can be absorbed by the ice and water in the other .
- **Check Food Storage:** Improperly stored, rotten, or strong-smelling foods (like fish, onions, or coffee) are the main culprits. Make sure all food is wrapped tightly in airtight, moisture-proof packaging .
- **Clean the Interior:** If you suspect an odor, the solution is to thoroughly clean both the refrigerator and freezer compartments. A simple wipe-down of spills and old food residue can make a significant difference .
- **Discard Old Ice:** Ice can absorb odors and become stale over time. Empty the ice bin and throw away old ice. This allows the ice maker to produce a fresh batch, which takes about 24 hours . As a good practice, empty and refresh the ice bin every 2 to 4 weeks .
- **Dispenser Maintenance:** The dispenser pad, nozzle, and ice chute should be wiped down weekly with a clean cloth to prevent buildup of residue .
### 4. Additional Maintenance and Specific Models
For some specific models, like those with a manual water tank inside the door, there are additional steps.
- **Manual Water Tanks:** If your model has a manually filled water tank, it should be cleaned periodically. Unhook the tank, disassemble the lid and valve, and wash all parts with warm, soapy water. Rinse thoroughly to remove all soap residue before refilling .
- **Temperature Settings:** Keeping your refrigerator at the recommended temperature (typically 37°F for the fresh food section and 0°F for the freezer) can help slow the growth of odor-causing bacteria .
**If the problem persists** after you have tried all these steps, you may need to consider that a more significant issue with your home's water supply is the root cause. In that case, a whole-home water filtration system might be a more permanent solution.
