KitchenAid Refrigerator Water Tastes Like Chemicals/Plast... | appliancefaults.com

Technical Background:

The refrigerator's MCU controls the water valve based on user input. Voltage is applied to the valve solenoid to open the water line. The water passes through the filter and into the reservoir or directly to the dispenser. Contamination can occur at any point along this path.

Symptoms:

The homeowner observes that the water dispensed from their KitchenAid refrigerator tastes like chemicals or plastic, even after flushing the system. This occurs after filter replacement or initial system.

Possible Causes:

New refrigerator system
Water filter not properly installed or compatible
Water filter housing contamination
Degrading water lines
Stagnant water in reservoir
Defective water tank

Solution:

1

Disconnect the refrigerator from the power outlet.
2

Turn off the water supply valve to the refrigerator.
3

Remove and inspect the water filter, ensuring it is the correct KitchenAid filter and properly seated.
4

Flush the water dispenser for 5 minutes (approx. 2.5 gallons) to remove any residual manufacturing debris. Collect and discard the water.
5

Inspect the water filter housing for cracks or discoloration. If found, replace the housing.
6

Replace the water filter with a new, genuine KitchenAid filter.
7

Flush the water dispenser again for 3 minutes (approx. 1.5 gallons).
8

Taste the water. If the chemical/plastic taste persists, consider replacing the water lines and reservoir.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any maintenance. Verify power is off using a non-contact voltage tester. Water and electricity can create a shock hazard.

Prevention:

Replace the water filter every 6 months with a genuine KitchenAid filter. If the refrigerator is unused for an extended period, flush the water dispenser for 5 minutes before use.

Expert Tip:

Some KitchenAid models have a service mode that allows for extended flushing cycles. Consult the service manual for your specific model to access this feature.

Frequently Asked Questions

•What is the correct part number for the water filter for my KitchenAid refrigerator?

Locate your refrigerator's model number (usually inside the refrigerator compartment) and search for compatible water filters on the KitchenAid website or parts distributor. Using the wrong filter can cause problems.

•How do I access the water lines to inspect them for degradation?

Access to the water lines typically involves removing the rear panel of the refrigerator. Be sure to disconnect power and water before proceeding. Inspect the lines for cracks, kinks, or discoloration. Replace any damaged lines with the appropriate replacements.

•What type of material are the water lines made of, and are there any specific types I should avoid?

Most refrigerator water lines are made of polyethylene or PEX. Avoid using copper tubing directly connected to the refrigerator, as it can cause galvanic corrosion. Ensure any replacement lines are NSF certified for potable water use.
