Error code E1 on LG model LD-14AW2 - LG 24 in. LD-12BW5 Free-standing Dishwasher

SOURCE: LG LD-14AW2 (03 error)

agreed O3 is not a LG error code. OE is more likely and if so it could be the main pcb faulty, a blocked drain pump or a blocked spigot under the sink where the drain hose connects onto.

take care.

IE is inlet error, displayed when "Not reached to the normal water level in spite of 10 min. water supply"

Possible cause:

• The Water Supply Tap is closed.
• The Water Supply is shut off.
• The Inlet Hose is kinked.
• The Water Pressure is very low.(below 10 psi)
• Inlet Valve is OK?
• The filter of Inlet Valve is clogged by impure water.
• The Hall sensor is OK?
• The Impeller of Air Guide is bound.

• Take action on Water Supply device.
• Measure the electric resistance of Inlet Valve. (950-1300 )
• Clean the filter of Inlet Valve.

• Replace the Air Braker.

The E1 error is telling you that there is a leak in the dishwasher. After confirming that there is no leak, even directly under the dishwasher (remove the kickplate and use a flashlight.)
After ruling that out, your problem is almost certainly caused by the drain hose between your dishwasher and your drain. There MUST be a 30" rise in the drain hose between the DW and the drain. If the hose just lays there, causing a siphoning effect (law of physics) that WILL drain water out of the dishwasher into the drain as soon as a wash or rinse cycle begins (after 1 - 2 minutes after they begin. Then the E1 error will be displayed.
The BEST way to fix this problem is to install an AirGap valve (almost free @ any hardware store) in your counter/sink and then running the short pipe to your disposal or sing drain inlet. If that is not possible or for a quick and dirty repair until you can install the AirGap, tie the drain hose to the bottom of the counter top so the rise is created.
Good Luck!

If you've checked everything, you will need to replace the impeller possibly.


Leakage error > Conditon: Excessive RPM of washing motor happened during wash cycle due to water leakage. Possible cause: Water leakage in hose connections,water is leaked by damages. The motor water seal leakage of sump assembly. The height of drain hose connection ( sink drain hose ) is not over 20". Impeller of the washing pump is worn away.
