Answer to continue safely
Is it safe to keep using?
No. Running a cycle without adequate water can damage the wash pump and heating element, which are not designed to operate dry. Do not attempt to run the dishwasher until the IE code is resolved.
Can I reset the code?
Yes. After addressing the water supply issue, reset the dishwasher by holding Power for 3–5 seconds or cycling the breaker. The IE code will clear once water fills normally.
When to stop immediately?
Stop if you notice: IE code returns immediately even with confirmed full water pressure at the valve., Water is dripping from the inlet valve connection at the back of the unit..
Symptoms You May Notice
Dishwasher Fills Very Slowly or Not at All
The tub remains empty or barely fills during the fill phase of the wash cycle before the error trips.
IE Code on Display
The control panel shows IE shortly after a cycle begins, usually within the first few minutes.
No Water Sound at Cycle Start
You cannot hear water rushing into the tub in the first 60–90 seconds of the wash cycle.
Extended cycle times
The dishwasher takes significantly longer than normal to complete a cycle as it repeatedly tries to fill to the correct water level.
Possible Causes
Closed or Restricted Water Supply Valve
The shut-off valve under the sink is fully or partially closed, limiting the water flow to the dishwasher inlet valve.
DIY PossibleClogged Inlet Valve Screen
Mineral scale or debris on the small mesh screen inside the water inlet valve blocks water from entering the machine.
DIY PossibleFaulty Water Inlet Valve Solenoid
The electromagnetic solenoid that opens the inlet valve has failed and will not open when energized by the control board.
Requires ProfessionalSafe Checks You Can Do
-
1
Verify the Water Supply Valve Is Fully Open
Locate the hot water shut-off valve under the sink where the dishwasher supply hose connects. Turn it fully counterclockwise to ensure it is completely open.
-
2
Inspect and Clean the Inlet Hose Screen
Turn off the water supply, disconnect the inlet hose at the back of the dishwasher, and look for the small mesh screen inside the fitting. Rinse it under water and use a soft brush to clear mineral buildup.
-
3
Check Household Water Pressure
LG dishwashers require 20–120 PSI. If other faucets in the home also have low pressure, the issue is with the home supply, not the appliance. Contact your water utility or a plumber.
When to Call a Professional
Contact a qualified technician if:
- Inlet valve solenoid coil tests open (infinite resistance) on a multimeter.
- Control board is not sending 120V signal to the inlet valve during fill phase.
- Water pressure at the connection point is within spec but valve still won't open.
