IE means LG LDT7808SS did not reach its expected water level; tap position, inlet hose and household supply should be checked before parts. Use the exact code to separate water inlet, drainage, foam, leak protection and internal faults. Do not order a part until the visible installation and removable filters have been checked. A closed tap, frozen or kinked line, low pressure or clogged inlet screen can slow filling until the control times out. IE occurs while filling and usually has little water in the tub; OE occurs while draining with water left behind. Open the tap fully, verify other cold-water flow, remove kinks from the accessible hose and clean only the connection screen after closing water and unplugging. Run a short cycle and listen for a sustained fill. If IE returns with adequate pressure, LG service should test the inlet system.
Models covered
Safety first
- Wear gloves around the sump because broken glass may be hidden. Do not tilt a built-in appliance or remove its base, side panels or wiring cover.
What the symptom may indicate
Checks in the right order
- Confirm the pattern
A closed tap, frozen or kinked line, low pressure or clogged inlet screen can slow filling until the control times out.
- Prepare safely
Cancel the cycle, switch the dishwasher off, close the water valve and wait for hot water and dishes to cool before touching a filter or hose.
- Apply the official check
Open the tap fully, verify other cold-water flow, remove kinks from the accessible hose and clean only the connection screen after closing water and unplugging.
- Retest once
Run a short cycle and listen for a sustained fill. If IE returns with adequate pressure, LG service should test the inlet system.
Stop and get qualified help when
- Stop and arrange service for water in the base, a heat or motor code, a leak that continues with the valve closed, or a code that returns after one empty test.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
