Whirlpool WRS325SDHZ Refrigerator: Metallic Taste in... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) in the Whirlpool WRS325SDHZ controls the dispenser valve by providing 120V AC to the valve solenoid. The water travels through internal tubing from the water inlet valve, through the filter, and to the dispenser valve. Any corrosion or degradation in this path can leach metallic ions into the water, causing the taste issue.

Symptoms:

The homeowner reports that the water dispensed from their Whirlpool WRS325SDHZ side-by-side refrigerator tastes like metal or copper. This affects all dispensed water and ice produced.

Possible Causes:

Corroded water filter
Degrading water lines
Saddle valve corrosion (if installed)
Internal refrigerator plumbing corrosion
Dispenser valve issues

Solution:

1

Turn off the refrigerator's water supply. Locate the shut-off valve, typically under the sink or behind the fridge.
2

Replace the water filter with a new Whirlpool-approved filter (every 6 months). Note the install date on the filter housing.
3

Inspect the water lines (plastic or copper) from the shut-off valve to the refrigerator for any kinks, damage, or corrosion.
4

Check the saddle valve (if present) for corrosion. If corroded, replace it with a new lead-free ball valve.
5

Flush the water dispenser for 5 gallons of water to remove any residual metallic taste.
6

Check the water pressure. Ideal pressure should be between 30-100 PSI. Use a water pressure gauge.
7

If the taste persists, suspect internal plumbing. Contact a qualified appliance repair technician.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. The dispenser valve operates on 120V AC - avoid contact with live wires.

Prevention:

Replace the water filter every 6 months as recommended by Whirlpool. Use only Whirlpool-approved filters. Inspect water lines regularly for leaks or damage. Ensure proper water pressure is maintained to prevent stress on the system.

Expert Tip:

To access the service mode on this model, simultaneously press and hold the Ice Type and Lock buttons for 3 seconds. This will allow you to run diagnostic tests on the dispenser valve and other components.

Frequently Asked Questions

•What type of water filter does my refrigerator use?

The Whirlpool WRS325SDHZ uses the W10413645A or comparable EveryDrop filter. Check your owner's manual for the exact part number.

•How do I check the water pressure going to my refrigerator?

You can purchase a water pressure gauge at most hardware stores. Connect it to the water line near the shut-off valve to measure the pressure.

•If the water filter is new, what else could cause the metallic taste?

If the filter is new, the most likely cause is corrosion in the water lines or the dispenser valve itself. Internal plumbing issues are also a possibility but less common.
