Why Does My Dishwasher Flash Error Codes?

Error codes pop up when your LG dishwasher detects something isn’t quite right. It could be as simple as a clogged filter (quick fix!), or it might need a little more attention. These handy codes are there to save you time and pinpoint the issue, so you’re not guessing in the dark.

Now let’s jump into the most common LG dishwasher troubleshooting codes and how you can tackle them step-by-step!

Common LG Dishwasher Error Codes (and How to Fix Them!)

Error Code	Description	How to Fix
AE	Leak Alert Water leakage detected in the dishwasher	Check for water pooling at bottom/underneath Verify dishwasher is properly leveled Inspect door gasket for damage Check water connection hoses
OE	Drainage Problem Dishwasher unable to drain water properly	Clean dishwasher filter Check drain hose for kinks Clean sink’s garbage disposal
HE	Heating Issue Problems with water heating system	Verify home water heater operation Check heating element (professional service may be required) Note: This may require professional repair
IE	Water Fill Problem Dishwasher not filling with water	Confirm water supply is turned on Check water hose for blockages Inspect inlet valve for damage
E1	Low Water Level Insufficient water detected	Verify water supply line is fully open Check for leaks in water line Inspect water inlet valve
PF	Power Failure Power interruption during cycle	Press power button to restart Check circuit breaker/power outlet Simple reset usually resolves this issue
CL	Child Lock Child lock feature activated	Hold child lock button for 3-5 seconds Check manual for specific button combination Not an error – this is a safety feature

1. AE Error Code – Leak Alert

Your dishwasher is sounding the alarm that water may be leaking. Yikes! But don’t panic yet sometimes this can be an easy fix.

What to Do:

Check for water pooling at the bottom of the dishwasher or underneath it.
Make sure the dishwasher is level tilted machines can trigger a false leak alert.
Inspect the door gasket (the seal around the door) for cracks or damage. If it’s worn out, a simple gasket replacement might solve the issue.
Double-check your water connections to ensure no hoses are loose.

2. OE Error Code – Drainage Problem

The OE code means your dishwasher is having trouble draining water. It’s likely clogged somewhere along the way.

How to Fix It:

Examine the dishwasher filter (it’s usually at the bottom) and remove any food debris or gunk. Gross but oh-so-satisfying!
Inspect the drain hose for kinks or blockages.
If the issue continues, try cleaning the sink’s garbage disposal sometimes a clogged disposal can affect the dishwasher’s drainage.

3. HE Error Code – Heating Issue

Uh-oh! Your dishwasher is having trouble heating the water. This is super important because hot water helps clean those dishes sparkling clean!

Steps to Troubleshoot:

Ensure the water heater in your home is working properly and delivering hot water to your dishwasher.
If everything checks out but the issue persists, the problem could be within the heating element. You might need a professional for this one (or an adventurous DIY spirit!).

4. IE Error Code – Water Fill Problem

This code means your dishwasher isn’t filling up with water as it should.

What to Check:

Is the water supply turned on? This one might seem silly, but hey it happens to the best of us!
Inspect the water hose for any bends, blockages, or clogs stopping the flow.
Check the inlet valve, which controls water entry into the dishwasher. If it’s damaged, it’ll likely need to be replaced.

5. E1 Error Code – Low Water Level

Your dishwasher thinks it doesn’t have enough water to run properly.

How to Fix It:

Ensure the water supply line is fully open.
Double-check for leaks or blockages in the water line.
If the issue continues, the water inlet valve might need replacement.

6. PF Error Code – Power Failure

This is your dishwasher’s way of telling you it lost power during a cycle.

The Quickest Fix:

Press the power button to restart the dishwasher.
Check your circuit breaker or power outlet to ensure the dishwasher has proper power supply. That’s it easy!

7. CL Message – Child Lock

Not technically an error code, but this confuses so many people! The “CL” message means the child lock feature is activated, stopping the buttons from working.

How to Unlock:

Look for the child lock button (or button combo, depending on your model) in your dishwasher’s manual. Then hold it down for 3–5 seconds. Voilà!

Pro Tips to Prevent Future Dishwasher Issues

You know what they say prevention is better than cure! Here are a few insider tips to keep your LG dishwasher running smoothly day after day:

General FAQ’s about LG Error Codes

Q1. Why is my LG dishwasher showing an error code instead of just stopping?
A1. LG dishwashers use error codes to point you toward the system that detected a problem (fill, drain, motor, leak, heat, sensors) so you can narrow down where to troubleshoot instead of guessing.

Q2. Can I clear an LG error code just by resetting the dishwasher?
A2. Many temporary glitches clear by turning the power off at the breaker or unplugging the unit for 1–2 minutes, then restarting a cycle, but if the underlying issue remains (like a clog or leak), the error will usually come back.

Q3. When should I stop DIY and call a technician for an LG error code?
A3. If you see repeat codes related to heating, motor, or sensor circuits after basic checks, or you smell burning or see water leaking underneath, it is safer to have a professional diagnose and repair the unit.

IE / 1E – Water inlet / fill error

Q4. What does IE (or 1E) mean on my LG dishwasher?
A4. IE (sometimes shown as 1E) indicates a fill error, meaning the dishwasher did not reach the correct water level in time, often due to low supply, a closed valve, or a restricted inlet filter.

Q5. How can I fix an IE code myself?
A5. Confirm the household water valve to the dishwasher is fully open, ensure water pressure is normal, then clean the inlet filter or screen on the water supply hose and restart the cycle.

OE – Drain error

Q6. What does OE mean on an LG dishwasher?
A6. OE indicates the dishwasher senses a drain problem, commonly caused by a kinked hose, food debris in the filter, or a partially blocked drain pump or sink connection.

Q7. What are basic steps to clear an OE code?
A7. Clean the filter and sump, check that the drain hose is not kinked or frozen and is installed correctly, then inspect where the hose ties into the garbage disposal or sink drain for clogs before running a test cycle.

AE / E1 – Leak detected

Q8. What does AE or E1 mean on my LG dishwasher?
A8. AE or E1 usually means the leak sensor or float switch has detected water in the base of the machine, which can come from an internal leak, over-sudsing, or the unit being badly out of level.

Q9. Can I just dry the water and reuse the dishwasher after an AE/E1 code?
A9. You can carefully dry any water in the base once power is disconnected and allow time to air out, but you must also address the cause such as a loose hose, door seal issue, or wrong detergent or the error is likely to return.

FE – Overflow / overfill error

Q10. What does FE mean on an LG dishwasher?
A10. FE indicates an overfill condition, where the dishwasher has detected too much water and activates the drain pump to prevent flooding.

Q11. What commonly causes an FE code?
A11. FE can result from a stuck water inlet valve that keeps letting water in, a faulty water level sensor, or foam and false water-level readings from using regular dish soap instead of automatic dishwasher detergent.

HE / tE – Heating and temperature errors

Q12. What does HE mean on my LG dishwasher?
A12. HE is a heater error, meaning the unit could not heat the water properly or detected overheating beyond a safe temperature range.

Q13. What does tE mean on an LG dishwasher?
A13. tE is a thermal error linked to the temperature sensor (thermistor), triggered either by abnormally high water temperature or by a problem with the sensor or its wiring.

Q14. Are HE and tE errors safe to troubleshoot at home?
A14. You can check for obvious issues like water supply temperature, power interruptions, and attempt a reset, but deeper checks of the heater or thermistor should be done by a qualified technician for safety.

Q15. What does LE mean on an LG dishwasher?
A15. LE points to a motor fault, often related to the circulation motor being locked, overloaded, or having wiring or sensor issues.

Q16. Why would loading dishes wrong cause an LE error?
A16. If items block the spray arms or restrict water movement, the circulation motor can struggle, drawing excessive current and triggering an LE motor protection code.

Q17. What does nE mean on an LG dishwasher?
A17. nE is associated with the vario motor that adjusts the spray arms and appears when the dishwasher detects abnormal feedback or movement from that motor.

Q18. What is the bE error on some LG dishwashers?
A18. On certain models, bE can indicate a motor-related malfunction or an issue tied to detergent and leveling, and it often shows up when the wrong detergent is used or the unit is not level.

Q19. What does PF mean on my LG dishwasher?
A19. PF indicates a power failure or interruption during operation, designed to protect the electronics and alert you that the last cycle did not complete normally.

Q20. What should I do after a PF code appears?
A20. Verify the outlet and breaker are stable, avoid using long extension cords, then restart and select a fresh cycle; if PF recurs without household power issues, have the control and wiring checked.

Cr / CD / 2-digit codes

Q21. What does Cr mean on an LG dishwasher?
A21. Cr usually indicates the dishwasher is in a continuous test mode used by installers and service technicians, not a fault in normal operation.

Q22. How do I exit Cr test mode?
A22. Power the dishwasher off, wait briefly, and turn it back on; if it stays in test mode, consult the service instructions or contact support, as some models require a specific button sequence.

Q23. My LG shows numbers like 01–24; is that an error?
A23. A two‑digit number between 01 and 24 on many models indicates a delay start time, showing how many hours remain before the wash actually begins, rather than a fault code.

Q24. What does CD mean after a quick cycle?
A24. CD on some models is not an error but indicates a cool and dry stage running after a cycle to help reduce moisture on dishes.

Practical use and prevention

Q25. How can I reduce the chance of LG error codes in everyday use?
A25. Use only automatic dishwasher detergent, periodically clean filters and spray arms, load dishes so spray arms spin freely, keep the unit level, and check hoses and connections for drips or kinks during routine kitchen maintenance.
