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

Technical Background:

The refrigerator's main control unit (MCU) manages the water dispensing system. When the dispenser is activated, the MCU energizes the water inlet valve, allowing water to flow through the filter and dispenser. Voltage paths involve 120V AC from the breaker panel to the MCU, then a lower voltage DC signal to the valve relay. Filter quality greatly affects water taste and purity.

Symptoms:

The water dispensed from the refrigerator's water dispenser tastes like plastic after a new water filter has been installed.

Possible Causes:

Incorrect filter system
New filter off-gassing
Contaminated water lines
Defective filter
Water reservoir contamination
Fridge has been sitting unused for a long period.

Solution:

1

Disconnect the refrigerator from power by unplugging it or switching off the dedicated breaker (15 or 20 amp) in the breaker panel.
2

Remove the new water filter following the manufacturer's instructions.
3

Using a clean container, run 2-3 gallons of water through the filter housing without the filter installed, using the dispenser. This helps flush out any initial contaminants.
4

Reinstall the water filter, making sure it clicks or locks securely into place. An improperly installed filter can cause taste issues.
5

Dispense 5-7 gallons of water, discarding the water. This allows the filter to properly saturate and flush out any remaining off-gassing.
6

Taste the water. If the plastic taste persists, replace the filter with a different brand or a certified OEM filter. Aftermarket filters can sometimes have quality control issues.
7

If the taste continues, and the reservoir is accessible, sanitize it with a baking soda solution as mentioned above.

Safety Warning:

Always disconnect power to the refrigerator before performing any maintenance or repairs. Use Lock-Out/Tag-Out (LOTO) procedures to ensure the power remains off during work. The refrigerator operates on 120V AC, which can cause serious injury or death if not handled properly.

Prevention:

Replace the water filter every 6 months or as recommended by the manufacturer. Use only certified water filters that meet NSF standards. Consider flushing the water lines after extended periods of non-use.

Expert Tip:

Some Admiral refrigerators have a service mode. To enter service mode, simultaneously press and hold the 'Energy Saver' and 'Door Alarm' buttons for 5 seconds. You can then run a dispenser test to ensure proper flow and diagnose potential issues.

Frequently Asked Questions

•How do I sanitize the water reservoir if it's not easily accessible?

If the reservoir is not accessible, try using a refrigerator cleaning spray designed for water lines and dispensers. Follow the product instructions carefully, ensuring thorough rinsing after application.

•What are NSF standards for water filters?

NSF standards certify that the filter has been tested and proven to reduce specific contaminants, such as chlorine, lead, and pesticides, improving water quality and taste. Look for NSF/ANSI Standard 42 (aesthetic effects) and Standard 53 (health effects) certifications.

•How do I locate the model number on my Admiral refrigerator?

The model number is typically located inside the refrigerator compartment, either on the upper left or right sidewall, or on the ceiling. It may also be found on a sticker on the back of the refrigerator.
