Quick answer
Start with the dispenser control state, then distinguish a water-flow restriction from an ice-bin or door-sensor interlock. LG says a locked panel, kinked supply line, clumped ice, or a door switch that still reports an open door can stop dispensing. If the dispenser stays silent after these accessible checks, arrange service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Look for a lock icon or error message and hold the control-lock key for the model-specified interval before trying water or ice again.
Expected result: The controls were locked or an error is displayed, or the control state is normal.
Next step: Unlock only through the normal control and record any error instead of guessing at its meaning.
Why this matters
Why: A lock intentionally disables most controls; an error may require the model's separate diagnostic procedure.
-
Check 2
Select water and press the lever while listening for a pump or valve hum; then inspect the accessible home valve and supply line for a closed valve or kink.
Expected result: The dispenser hums but water does not flow, or it is silent.
Next step: Restore an accessible valve or line position; do not disconnect pressurized fittings.
Why this matters
Why: A hum with no flow points toward supply, line, filter, or inlet restriction; silence makes an interlock or electrical control more likely.
-
Check 3
For an ice request, check that the ice bin is present and that cubes are not frozen into one solid mass.
Expected result: The bin is empty, misseated, or clumped, or ice is loose but still does not move.
Next step: Correct the bin position and only remove loose clumps safely; never force the auger.
Why this matters
Why: No available ice or a bridged bin can stop the auger even when the water dispenser works.
-
Check 4
With the doors closed, press each accessible door switch or use the model's magnetic-sensor check and watch whether the interior lights turn off.
Expected result: A light remains on or the dispenser still does not respond when the sensor is actuated.
Next step: Stop at the sensor check and arrange service if the interlock does not change.
Why this matters
Why: LG notes that the refrigerator may inhibit dispensing when it believes a door is open; a switch, sensor, or hinge connection may be at fault.

-
PATH 01Next step
What you see
The panel was locked and dispensing returns after the normal unlock
Do this next
Leave the lock behavior documented for future use and monitor both water and ice.
-
PATH 02Next step
What you see
Water produces a hum but no stream while ice is available
Do this next
Check only the accessible valve, line, and model-approved filter path, then request service.
-
PATH 03Next step
What you see
Both water and ice are silent and interior lights do not switch off during the sensor test
Do this next
Do not bypass the sensor; obtain qualified service.
Helpful context
Understand the symptom
Start with the symptom
Water and ice can share the lever but not the same immediate cause. The key observation is whether the unit hums when commanded and whether the interior lights respond to the door-switch test.
When checks do not resolve it
Need a professional?
Request service if the dispenser remains silent, a door sensor fails, an error persists, water leaks, or accessible supply and bin checks do not restore operation.
Common questions
FAQ
Why does LG dispensing stop when a door is open?
LG says the dispenser may not operate when the refrigerator believes a door is open. Door switches or magnetic sensors also control the interior lights, so that light response helps separate an interlock issue from a water-flow issue.
Why does the dispenser hum but deliver no water?
A hum with no water can indicate that the home valve is closed, the line is kinked, or another supply path is restricted. Check only accessible conditions and arrange service if flow does not return.
