Frigidaire PurePour Water Filter Bypass: A Step-by-Step... | appliancefaults.com

Technical Background:

The MCU monitors water flow and filter status using sensors. It interprets sensor data and controls the water valve. A voltage path exists between the MCU and the water valve, typically operating at 12V DC or less. Filter replacement resets are often handled through a user interface which sends a signal to the MCU.

Symptoms:

The homeowner observes low water flow from the dispenser, no water at all, or a "replace filter" light that won't reset even after replacing the filter. They may also notice an unusual taste or odor in the water.

Possible Causes:

Clogged water filter restricting water flow.
Faulty water filter head or housing.
Malfunctioning water valve controlling water flow to the filter.
Defective MCU (Main Control Unit) incorrectly signaling filter status.
Air lock in the water line after filter replacement.
Sediment buildup in the water lines.

Solution:

1

Unplug the refrigerator from the 120V AC outlet.
2

Shut off the water supply valve. Check the water pressure (typically 40-60 PSI). Low pressure can mimic a clogged filter.
3

Remove the existing water filter. Inspect the filter head for cracks or damage. Check the O-rings for deterioration.
4

Attempt to bypass the filter by using a bypass plug. If one is not available, order the correct bypass for the specific model.
5

With the bypass plug installed, slowly turn the water supply back on and check for leaks at the housing. Use a flashlight to inspect hard to reach areas.
6

If leaks are present, replace the filter head. These are commonly secured with T-20 Torx screws. Ensure the new head is tightened properly.
7

If no leaks are observed, run the water dispenser for 3 minutes to clear any trapped air. Check the water flow. It should fill an 8oz glass in approximately 8-10 seconds. If the flow is still restricted, the inlet valve may be the issue.

Safety Warning:

Always disconnect the refrigerator from the power source before attempting any repairs. Shut off the water supply to prevent flooding. Water and electricity can create a dangerous shock hazard. If you're not comfortable working with plumbing or electrical components, contact a qualified appliance technician.

Prevention:

Replace the water filter every 6 months, even if the "replace filter" light isn't illuminated. This prevents sediment buildup and maintains optimal water quality. Consider installing a whole-house water filter to reduce sediment entering the refrigerator's water lines.

Expert Tip:

Some Frigidaire models have a service mode. To access it, simultaneously press and hold the "Ice Type" and "Lock" buttons for 3 seconds. This may allow you to manually reset the filter timer or diagnose other issues. Consult the service manual for your specific model.

Frequently Asked Questions

•How do I know if my water filter head is cracked?

Carefully inspect the filter head for hairline cracks, especially around the filter connection points. Look for signs of water leakage or staining near the head. A cracked filter head often requires replacement.

•What if the water flow is still low after bypassing the filter?

If the water flow is still restricted after bypassing the filter, the issue likely lies with the water inlet valve or the water supply line itself. Check the water pressure at the valve using a water pressure gauge. The valve may need replacing if it is faulty.

•Where can I find a bypass plug for my specific Frigidaire model?

You can purchase a bypass plug from most appliance parts retailers, both online and in brick-and-mortar stores. Be sure to have your refrigerator model number handy to ensure you get the correct bypass plug. Search for 'Frigidaire [Your Model Number] water filter bypass'.
