Frigidaire PureSource 3 Water Dispenser Dripping After... | appliancefaults.com

Technical Background:

The water dispenser is controlled by the Main Control Unit (MCU), which activates a solenoid valve when the dispenser paddle is pressed. The MCU sends a 12V DC signal to the valve. After filter replacement, air can get trapped or the filter head may not seal correctly causing the valve to not fully close. The voltage path must be clean to guarantee a fully closed solenoid valve.

Symptoms:

US homeowner observes a persistent drip from the water dispenser of their Frigidaire PureSource 3 refrigerator immediately after replacing the water filter.

Possible Causes:

Improper filter system
Air trapped in the water lines
Faulty water filter head
Damaged O-rings on the filter or filter housing
Cracked or leaking water lines connected to the dispenser
Low water pressure to the refrigerator

Solution:

1

Turn off the water supply to the refrigerator at the shut-off valve (usually located under the sink).
2

Remove the water filter and inspect it for damage. Check the O-rings for proper seating and any signs of wear or damage.
3

Reinstall the water filter, ensuring it is properly seated and locked into place. Follow the manufacturer's instructions.
4

Turn the water supply back on slowly and observe the water dispenser for any leaks.
5

If dripping persists, use a water pressure gauge to test the water pressure at the inlet valve of the refrigerator. It should be between 30-100 PSI. Low pressure can cause dripping.
6

If the pressure is within range, disconnect the water line from the filter housing. Inspect the housing for cracks or damage.
7

With the water line disconnected use a 5/16-inch nut driver to remove the water valve and check for any cracks or damage.

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. Be aware of potential water leaks and electrical hazards. Some components operate at 120V AC.

Prevention:

Replace the water filter every 6 months, or as recommended by the manufacturer. When replacing, lubricate the O-rings with food-grade silicone grease to ensure a proper seal. After replacement, dispense several gallons of water to purge any trapped air from the system.

Expert Tip:

After installing the new filter, hold the water dispenser lever for 5 minutes to purge any trapped air. If the dripping continues, enter service mode by pressing and holding the 'Ice On/Off' and 'Lock' buttons simultaneously for 3 seconds. Run a dispenser calibration cycle. This often resets the system and resolves minor issues.

Frequently Asked Questions

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

You'll need a water pressure gauge. Connect it to the water inlet valve on the back of the refrigerator. The gauge will display the water pressure in PSI (pounds per square inch). Optimal range is usually 30-100 PSI.

•What type of food-grade silicone grease should I use on the O-rings?

Use NSF-certified food-grade silicone grease. This ensures it's safe for contact with potable water. A small amount applied to the O-rings will help them seal properly.

•If I replace the filter head, are there any special installation considerations?

Yes. Ensure the new filter head is compatible with your refrigerator model. Carefully disconnect the water lines, noting their positions. When reconnecting, use new compression fittings and ensure they are tightened properly to prevent leaks. Test for leaks after installation.
