Answer to continue safely
Is it safe to keep using?
Maybe.
Can I reset the code?
Yes.
When to stop immediately?
Stop if you notice: Water is continuously flowing into the ice maker or leaking onto the floor, You notice water damage or pooling beneath or behind the refrigerator.
Symptoms You May Notice
No water dispensing from the door
Pressing the water dispenser lever produces no water flow, even though the water supply line is connected and the household water is on.
Ice maker not filling with water
The ice maker cycles but receives no water to freeze, resulting in empty trays and no ice production.
Water continuously dripping into ice maker
A valve stuck in the open position allows water to flow continuously into the ice tray, causing overflow and ice buildup around the ice maker.
Buzzing sound from the rear of the refrigerator
The solenoid valve vibrates audibly when it attempts to open but cannot due to mineral deposits restricting the plunger.
Possible Causes
Mineral deposit buildup in valve
Hard water deposits restrict the valve plunger, preventing it from opening fully to allow water flow or closing fully to stop it.
Requires ProfessionalFailed solenoid coil
The electromagnetic coil that actuates the valve plunger has burned out, so the valve cannot open when commanded by the control board.
Requires ProfessionalLow household water pressure
Water pressure below 20 psi is insufficient to push through the valve even when the solenoid opens. This can result from a partially closed shutoff valve or low municipal pressure.
DIY PossibleSafe Checks You Can Do
-
1
Check the water supply
Locate the water shutoff valve behind or beneath the refrigerator. Ensure it is fully open. If the valve has not been operated in years, turn it off and on to break any mineral buildup on the valve seat.
A saddle valve (the type that pierces the copper pipe) can clog over time — these are a frequent source of low water flow.

2
Test the water dispenser
Press the water dispenser lever and listen for a click or hum from the rear bottom of the refrigerator. This indicates the solenoid is being energized. If you hear nothing, the solenoid or its wiring may be faulty.
Have someone listen at the back of the fridge while you press the dispenser in front.

3
Replace the water filter
A clogged water filter can restrict flow enough to trigger valve errors. Remove the existing filter and try dispensing water with no filter temporarily to test. If water flows normally, the filter needs replacement.
Running the dispenser without a filter for a brief test is fine — just remember to install a new filter afterward.
When to Call a Professional
Contact a qualified technician if:
- The solenoid does not click or hum when energized during diagnostic mode testing
- Water pressure at the refrigerator connection tests below 20 psi
- The valve is visibly corroded or mineral deposits are present at the inlet screen
