Roper Refrigerator: Water Tastes Like Plastic After... | appliancefaults.com

Technical Background:

The refrigerator's water dispensing system includes a water filter, water lines, a water inlet valve, and the dispenser itself. The MCU controls the water inlet valve based on user input. Low voltage DC is typically used to actuate the water valve solenoids. Mineral build-up or plastic leeching into the water can affect the taste.

Symptoms:

US homeowner reports that the water from their Roper refrigerator tastes like plastic after replacing the water filter. The taste is persistent even after dispensing a significant amount of water.

Possible Causes:

New filter not properly flushed.
Incorrect filter system.
Manufacturing residue in the new filter.
Water line contamination.
Defective water filter housing or related components.

Solution:

1

Flush the new water filter: Dispense 2-3 gallons of water through the dispenser. This helps remove any manufacturing residue or air trapped in the filter.
2

Verify filter system: Remove and reinstall the filter, ensuring it's properly seated and locked into place. Check the filter housing for damage.
3

Inspect water lines: Check the water supply line (typically 1/4-inch OD) for kinks or damage. Inspect connections at the water inlet valve.
4

Check Water Filter Housing: Examine the water filter housing for cracks or damage. If damaged, replace the housing.
5

Sanitize the Water System: Mix 1 tablespoon of baking soda per quart of water. Flush this solution through the water dispenser, then follow with fresh water to rinse.
6

Replace Water Filter: If taste persists, try a different brand of water filter. Some aftermarket filters might have quality control issues.
7

Check the Water Inlet Valve: The water inlet valve solenoids should measure approximately 300-500 ohms. If outside this range, the valve may be faulty and need replacement.

Safety Warning:

Always disconnect the refrigerator from the breaker panel before performing any repairs. Water and electricity can create a dangerous shock hazard. Lock Out Tag Out (LOTO) procedures should be followed to ensure the refrigerator remains de-energized during servicing. High voltage is present in some components.

Prevention:

Replace the water filter every 6 months or as recommended by the manufacturer. Regularly flush the water dispenser to prevent stagnant water from accumulating in the lines.

Expert Tip:

Sometimes, using a genuine OEM filter instead of an aftermarket filter resolves persistent taste issues. Many refrigerators have a hidden service mode accessed by pressing and holding specific buttons. Consult the service manual for the specific button combination for your Roper model. Entering service mode allows you to manually activate components like the water valve for testing purposes.
