IE

Water Inlet Error

Severity

High

Your LG Dishwasher stopped working and is showing error IE, which corresponds to a fault called "Water Inlet Error". This is one of the most searched error codes for this appliance — you are not alone, and there is a clear fix.

Owner's Summary

Your LG dishwasher cannot detect water entering the machine. Check the supply valve under the sink first — it should be turned fully counterclockwise. This takes 5 seconds to check and fixes the majority of IE errors.

Symptoms

LG dishwasher not filling, pauses at beginning of wash, IE displayed

Common Causes

Water supply valve closed under sink
Low household water pressure
Clogged inlet valve screen
Faulty water inlet valve

How to Fix

1 Open water supply valve fully
2 Clean inlet valve filter screen
3 Check home water pressure
4 Replace inlet valve if it fails to open when energized

Tools You'll Need

Soft Brush Towels / Bucket

Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.

Technical Explanation

LG's main PCB energizes the inlet valve solenoid and monitors the turbidity or level sensor for a fill confirmation signal. If the expected signal change is absent within 4 minutes, the PCB de-energizes the valve and posts IE.

Is It Safe to Keep Using?

No immediate risk to the appliance.

Technician's Pro Tip

The inlet screen on LG dishwashers is located inside the solenoid valve body — not just at the hose connection. Disassemble the valve to access and clean the internal screen, which accumulates mineral deposits faster than the external screen.
