On the covered LG dishwasher platform, IE means an inlet error — the dishwasher is not filling correctly. First, check the water supply valve is fully open and the inlet hose is not kinked or frozen. Check whether the kitchen and bathroom taps run; if not, there may be an outage.
Differential
Likely causes of “LG dishwasher code IE”, and how to tell them apart
- 1
A water outage
What separates it No water comes from the kitchen or bathroom taps either
How to confirm Check whether the kitchen and bathroom taps run; if not, there may be an outage
- 2
A pressed or kinked inlet hose
What separates it The hose behind or under the unit is squeezed by an object
How to confirm LG says objects near the hose may press it; straighten the hose so water flows well
- 3
A closed water inlet valve
What separates it The dishwasher was newly installed or moved recently, which points to a closed water inlet valve
How to confirm The installer may have closed the valve to prevent leaks; turn it counterclockwise to open it
- 4
A shut-off valve that is closed
What separates it The inlet valve is open and the machine still gets no water
How to confirm LG says to ensure the shut-off valve above the inlet valve is also open
Before you touch a setting

ReversibleCheck the water supply valve is fully open and the inlet hose is not kinked or frozen.
Correct only the documented fault domain
ReversibleRestore the supply before treating the inlet valve as failed.
Check the household water
ReversibleRun the kitchen and bathroom taps; if there is no water, the likely cause is an outage and the dishwasher is fine.
Straighten the inlet hose
ReversibleEnsure the inlet hose is not pressed or kinked, look for objects placed near it, and straighten any bend so water flows freely.
Open both valves
ReversibleOpen the sink cabinet door below the taps, find the inlet hose to the dishwasher, turn the inlet valve anti-clockwise to open it, and open the shut-off valve above it the same way.
Run the machine again
ReversibleAfter the valves are open, run a cycle; if the code persists, LG says a detailed inspection by a technician is required.
