IE2
LG Dishwasher
Severity: ModerateWhat Does This Error Mean?
The IE2 error means your LG dishwasher couldn't fill with water on a second attempt. After failing once (IE), the machine retried and failed again. Something is blocking or restricting the water supply.
Affected Models
- LDF5545ST
- LDFN4542D
- LDT5678SS
- Select LG built-in dishwasher models
Common Causes
- The water supply valve under the sink is partially closed
- The inlet hose mesh filter is clogged with sediment
- Household water pressure is too low — below 20 psi
- The water inlet valve on the dishwasher is faulty or calcified
- The door wasn't fully closed, preventing the fill cycle from starting
How to Fix It
-
Check the water supply valve under your kitchen sink.
Turn it fully counterclockwise to make sure it's completely open.
-
Turn off the water supply and disconnect the inlet hose at the back of the dishwasher.
Look inside the hose fitting for the small mesh filter. Remove it and rinse it clean.
-
Turn on a kitchen tap to test household water pressure.
If water flow from the tap is weak, the problem may be with your home's water supply — not the dishwasher.
-
Unplug the dishwasher for 5 minutes, then plug back in.
This clears the error state and allows the machine to retry from a fresh start.
-
Close the door firmly and start a new cycle.
Listen for the sound of water entering the machine in the first 60 seconds. If you hear nothing, the inlet valve may be faulty.
When to Call a Professional
If you've checked the supply valve and hose with no luck, the inlet valve may need replacing. Inlet valve replacement costs $80–$200 including parts and labor. A technician can also test water pressure to confirm it meets the dishwasher's requirements. Do not force-run with IE2 active — the pump may run dry and get damaged.
Frequently Asked Questions
What is the difference between IE and IE2 on LG dishwashers?
IE is the first water inlet failure. IE2 means the machine tried again and failed a second time. IE2 is a stronger sign that the cause is a physical problem — not a temporary glitch.
Where is the inlet hose filter on my LG dishwasher?
It's a small plastic mesh screen inside the water inlet hose fitting. You'll find it at the back of the dishwasher where the hose attaches. Unscrew the hose, look inside the fitting, and pull out the screen with needle-nose pliers.
How much water pressure does an LG dishwasher need?
LG dishwashers typically require between 20 and 120 psi of water pressure. Below 20 psi, the inlet valve can't open far enough to fill properly. If your home pressure is borderline, a plumber can check and adjust it.
