No water sound at all
You start a cycle, hear a click or brief hum, but no rush of water into the tub before the code appears.
Start here: Check the dishwasher water shutoff valve first, then make sure the inlet hose is not kinked or flattened.
Dishwasher fill problem
LG Dishwasher IE Code
Direct answer: An LG dishwasher IE code usually means the dishwasher is not getting enough water during the fill window. Most of the time the cause is a closed or restricted water supply, a kinked dishwasher inlet hose, or debris at the dishwasher water inlet valve screen.
Most likely: Start at the sink cabinet or basement shutoff feeding the dishwasher, then check the dishwasher inlet hose for kinks and the tub float area for anything holding it up.
If the machine starts, hums, and then throws IE without much water entering the tub, stay on the fill side first. Reality check: a lot of IE calls end up being a half-open shutoff valve or a pinched line after something was stored under the sink. Common wrong move: replacing the dishwasher drain parts because the code showed up after a cycle stopped early.
Don’t start with: Do not start by ordering a control board or tearing the door apart. IE is usually a plain water-supply problem, not an electronic mystery.
What IE usually meansThe dishwasher did not sense a normal water fill in time.
Best first checkConfirm the dishwasher water supply valve is fully open and the inlet hose is not bent or crushed.

What the IE code looks like in real kitchens
A little water enters, then IE
The tub gets a small amount of water, then the cycle stops and shows IE.
Start here: Look for a restricted supply line, debris at the dishwasher water inlet valve screen, or low house water flow to the dishwasher branch.
IE started after moving things under the sink
The dishwasher worked before, then failed after cleaning, storing supplies, or recent plumbing work.
Start here: Inspect the dishwasher inlet hose for a sharp bend, crushed spot, or a shutoff valve that was bumped partly closed.
IE comes and goes
Some cycles fill normally and others fail, especially when other fixtures are running.
Start here: Suspect a weak water supply, a sticky dishwasher float, or a dishwasher water inlet valve that is starting to hang up.
Most likely causes
1. Dishwasher water supply valve partly closed or off
This is the most common real-world cause, especially after sink work, leak checks, or items being moved in the cabinet.
Quick check: Find the valve feeding the dishwasher and turn it fully open. Then run a new cycle and listen for a stronger fill sound.
2. Kinked or restricted dishwasher inlet hose
A bent braided line or crushed copper tube can cut flow enough to trigger IE even though some water still gets through.
Quick check: Look along the full visible length of the dishwasher inlet line for sharp bends, flattening, or rubbing where the machine was pushed back.
3. Debris at the dishwasher water inlet valve screen or a failing dishwasher water inlet valve
Sediment after plumbing work or an aging valve can slow fill enough to trip the code.
Quick check: If the supply valve is open and the hose is clear, shut power and water off, then inspect the inlet connection area for a clogged screen or signs the valve is not opening reliably.
4. Dishwasher float stuck up or float area blocked
If the float is held in the raised position by debris, a utensil, or buildup, the dishwasher acts like it is already full and stops filling.
Quick check: Inside the tub, make sure the float moves freely up and down and nothing is trapped around it.
Step-by-step fix
Step 1: Make sure this is really a fill problem
IE points to water not entering fast enough, but you want to separate that from a drain problem or a door-start issue before going deeper.
- Cancel the cycle and wait for the dishwasher to go quiet.
- Open the door and look in the bottom of the tub.
- If the tub is mostly dry, or only has a thin film of water, stay on this page and troubleshoot fill.
- If the tub is full of standing water, your main problem is likely draining, not filling.
- Start a fresh cycle and listen during the first minute for the normal sound of water rushing in.
Next move: If you clearly hear a normal fill and the code does not return, the issue may have been a temporary supply interruption. If there is no fill sound or only a weak trickle before IE returns, move to the water supply checks.
What to conclude: A dry tub with IE keeps the diagnosis focused on incoming water, not the drain side.
Stop if:
- There is standing water leaking onto the floor.
- You smell burning, see smoke, or hear harsh electrical buzzing.
- The dishwasher will not power on or latch closed at all.
Step 2: Check the dishwasher water supply valve and house-side flow
A partly closed valve is the fastest, safest, and most common fix.
- Find the dishwasher shutoff valve under the sink, in the basement below, or in the adjacent cabinet if the line is visible.
- Turn the valve fully open. If it is a multi-turn style, open it all the way, then back it off just a touch if needed.
- Look for signs the valve handle was bumped or left half-open after other work.
- If the dishwasher shares access space with other plumbing, note whether recent plumbing repairs or sediment events happened before the code started.
- Run the dishwasher again and listen for a stronger, steadier fill.
Next move: If the dishwasher now fills normally, the problem was restricted supply at the shutoff valve. If the valve is fully open and IE still returns, inspect the inlet line and tub float next.
What to conclude: Good supply at the shutoff rules out the easiest external cause and points you toward a restriction or component issue at the dishwasher.
Step 3: Inspect the dishwasher inlet hose and the float inside the tub
These are the next most common non-electrical causes, and both can stop filling without any failed electronics.
- Turn off power to the dishwasher at the breaker before reaching around the machine or under the toe kick area.
- Inspect the visible dishwasher inlet hose from the shutoff valve toward the dishwasher for kinks, crushing, or a sharp bend where the machine was pushed back.
- If the line is pinched by stored items or cabinet contents, clear the area and straighten the hose gently.
- Open the dishwasher and locate the float in the tub floor area if your model has an accessible one.
- Lift and lower the float gently to make sure it moves freely and is not held up by debris, scale, or a stray utensil.
- Clean around the float area with warm water and mild soap if there is greasy buildup.
Next move: If straightening the hose or freeing the float restores normal filling, run a full cycle and keep the cabinet area clear. If the hose is clear and the float moves normally, the next likely issue is restriction at the dishwasher water inlet valve or the valve itself.
Step 4: Check for a clogged dishwasher water inlet valve screen
Sediment at the valve inlet is a common cause after plumbing work, shutoff cycling, or older galvanized supply piping.
- Keep power off at the breaker and close the dishwasher water supply valve.
- Place a towel under the water connection area and disconnect the dishwasher inlet hose at the dishwasher water inlet valve if it is accessible.
- Look for grit, scale, or debris at the valve inlet screen.
- Rinse loose debris away with water and wipe the connection clean without poking hard into the screen.
- Reconnect the line, open the supply valve slowly, check for leaks, then restore power and test a cycle.
Next move: If the dishwasher fills normally after cleaning the screen, sediment restriction was the cause. If the screen was clear or the code returns right away, the dishwasher water inlet valve may be weak or sticking internally.
Step 5: Replace the failed fill-side part or call for service if the diagnosis is still muddy
By this point you have ruled out the easy supply problems. The remaining common repair is the dishwasher water inlet valve, with the float assembly as a secondary branch if it is clearly sticking or damaged.
- Replace the dishwasher water inlet valve if the supply valve is fully open, the inlet hose is not kinked, the float moves freely, the inlet screen is not blocked, and the dishwasher still will not fill properly.
- Replace the dishwasher float assembly only if the float is damaged, does not move freely after cleaning, or clearly stays in the full position when the tub is empty.
- After replacement, restore water and power, run a wash cycle, and watch the first fill and the first drain.
- If the dishwasher still shows IE after those checks and repairs, stop buying parts and schedule appliance service because wiring, control, or pressure-sensing faults need model-specific testing.
A good result: If the dishwasher fills with a normal rush of water and continues washing without IE, the repair path was correct.
If not: If IE remains after a confirmed good supply and a sound fill-side repair, the problem is beyond a smart guess-and-buy fix.
What to conclude: A confirmed fill-side part failure is repairable. An unresolved IE after the basic fill path checks usually needs hands-on electrical diagnosis.

FAQ
What does IE mean on an LG dishwasher?
It usually means the dishwasher did not fill with water fast enough. The most common causes are a closed or restricted water supply, a kinked inlet hose, a stuck float, or a weak dishwasher water inlet valve.
Can low water pressure cause an IE code?
Yes. If the dishwasher branch has weak flow, the machine may not reach its expected fill level in time. This can happen with a partly closed shutoff valve, sediment in the inlet screen, or low house pressure while other fixtures are running.
Will resetting the dishwasher clear the IE code for good?
A reset may clear the display once, but it will not fix the cause if water still is not entering properly. If IE comes back on the next cycle, go back to the supply and fill checks.
Should I replace the dishwasher water inlet valve right away?
No. Check the shutoff valve, inlet hose, and float first. Those are common and cheaper problems. Replace the dishwasher water inlet valve only after the supply path checks out and the dishwasher still will not fill normally.
Why did the IE code start after plumbing work?
That is common. A shutoff valve may have been left partly closed, the inlet hose may have been bumped or kinked, or sediment may have broken loose and collected at the dishwasher water inlet valve screen.
Can a clogged filter cause an IE code?
Usually no. A dirty dishwasher filter is more tied to draining and wash performance. IE is mainly about incoming water, not water leaving the tub.
