If your LG dishwasher IE error code appears immediately after starting a cycle, you are not alone. Many users face this issue, especially with LG Direct Drive inbuilt dishwashers. The machine starts, then suddenly stops and shows “IE” - which can be frustrating.
The good news is that this problem is usually fixable without replacing the entire unit.
Quick Answer
The LG dishwasher IE error code means the machine is not filling with water properly.
This is often caused by low water pressure, blocked filters, or faulty inlet valves.
Step-by-step solution to fix LG dishwasher IE error code
Step 1: Check water supply taps
Make sure both water supply taps are:
- Fully open
- Not partially blocked
Even a slightly closed tap can trigger the IE error code.
Step 2: Inspect water pressure
Your dishwasher needs enough pressure to function.
- Minimum required: 20 PSI
- If pressure is low:
- Check your house supply
- Ask a plumber if needed
Low pressure is one of the most common causes of this issue.
Step 3: Examine inlet hoses
Carefully inspect the water hoses for:
- Kinks
- Bends
- Pinched sections
Straighten any damaged areas to restore proper water flow.
Step 4: Clean water inlet filters
Blocked filters can stop water from entering.
- Disconnect water supply
- Locate the inlet filter screen
- Remove debris using:
- Tweezers
- Running water
This simple step often fixes the error instantly.
Step 5: Check for debris in the system
Sometimes dirt blocks internal parts.
What worked for many users:
- Disconnect hoses
- Remove visible debris
- Blow compressed air through hoses and valves
- Reconnect everything securely
This deep cleaning can restore normal operation.
Step 6: Inspect the water inlet valve
The water inlet valve controls water entry.
- If defective, the dishwasher won’t fill
- Test or replace it if needed
Even if water pressure is fine, a faulty valve can still cause the IE error.
Step 7: Check drainage and plumbing
Surprisingly, drainage issues can also trigger IE.
- Clean the P-trap
- Ensure no blockages
- Raise the drain pipe slightly to prevent backflow
This improves overall water flow in the system.
Step 8: Inspect wiring connections
Loose or damaged wiring can cause false IE errors.
- Check wiring at the side/back
- Look for:
- Broken wires
- Loose connections
Fixing wiring issues may resolve persistent errors.
Extra tips and best practices
- Always use the correct detergent (wrong ones can cause system errors)
- Recalibrate by restarting the dishwasher after fixing issues
- Perform regular maintenance cleaning every few months
- Ensure hoses are installed without tension
Common mistakes to avoid
- Ignoring water pressure issues
- Replacing parts before checking simple causes
- Forgetting to clean inlet filters
- Overlooking hose kinks behind cabinets
- Assuming the machine is broken immediately
