How to Keep the Dispensed Water Better Chilled

How Your Whirlpool Dispenser Cools Water

The dispensing system includes your home’s water supply line, a water inlet valve, a replaceable water filter, an internal water reservoir or chill loop inside the fresh food compartment, and the dispenser controls on the door.

Water cools as it sits in the internal reservoir or travels through tubing routed within the refrigerated section. When the compartment is at its set temperature, the stored water chills to near that level. The first glass after a long idle period is usually the coldest. If you draw multiple glasses back-to-back, you may exceed the reservoir’s capacity and pull in unchilled line water until the reservoir refills and cools again.

Factors that can warm dispensed water include a refrigerator set too warm, warm ambient room temperatures, frequent high-volume dispensing, and newly installed or recently flushed systems that have not cooled fully. Frequent door openings or placing warm items near the internal chill loop can also temporarily raise the water temperature.

Tips to Maintain Optimal Water Temperature

• Set temperatures correctly: Keep the refrigerator at 37°F to 40°F (37°F is ideal) and the freezer near 0°F for efficient cooling that supports the water reservoir.
• Replace the water filter regularly: Change the filter about every 6 months, or sooner if flow decreases or taste/odor changes. Proper flow helps the reservoir refill quickly and re-chill between uses.
• Purge after filter changes: After installing a new filter, dispense and discard 2 to 3 gallons (or the amount in your Use & Care Guide) to remove air and warm water, then allow several hours for the reservoir to cool.
• Protect airflow: Avoid placing hot containers in front of air vents or against interior walls where tubing or the reservoir may be located. Keep large, hot leftovers away from the back or side walls.
• Limit warm air entry: Minimize prolonged door openings to maintain a stable compartment temperature.
• Plan for multiple servings: For the coldest first pour, allow time between fills for the reservoir to re-chill. If you need several cold drinks quickly, fill a pitcher and store it in the refrigerator. Insulated cups or adding ice from the ice maker help keep beverages cold longer. Discard the first glass of water. Dispense enough water every week to maintain a fresh supply of chilled water.
