''IE'' error code on my LG dishwahser

LG has programmed in the E1 error code to indicate when the drain pump is running, it is not receiving the back pressure it needs. This is most likely an indication that there is a water leak in the draining system.

I think you may be getting IE code which relates to water inlet problems. Either the water pressure is low or the inlet valve may not be working properly.

But if it is LE code then see this page for suggested fix.

Hello

This means the unit isn't detecting water coming in the unit. If there is definitely water getting to the dishwasher, then you will need to replace the flow meter which is the part that detects the water entering the dishwasher when the valve opens.

Hi, according to the owner's manual on mine, "IE ERROR" means it's a 'water input error'. You have to check for a kink or clog to the water hose running to your machine. Once you unclog the water hose, you error code will disappear.

Hi

Error code IE on LG dishwasher means Inlet error. This error comes up when the Water Supply Tap is closed or Water Supply is shut off. If water supply is turned on then make sure that the Inlet Hose is not kinked and water Pressure is not low (should be above 10 psi). Next thing to check for is Water Inlet Valve, measure the electric resistance of Inlet Valve. (950-1300 ohms) Make sure the filter of Inlet Valve is not clogged.

Hope this helps... Please post back for further assistance.

le is pump bad

Please look one more time. The LG LDS 5811 dishwasher error codes are:

IE Error
OE Error
FE Error
E1 Error
HE Error
tE Error

It would also be helpful to know what happens when this error code displays. Please post back here, OK?

Thanks.

It sounds like the flood switch in the bottom of the washer is activated. check for water in the base as the machine if maybe leaking. This is a Dishwasher?

LE error code means that there is a problem with the motor.  One thing to check is to remove the front door panel and check the wiring harness to see if there are any broken wires.  If there is, repair the wire connections and see if the dishwasher returns to normal.  If not, then the motor assembly will need to be replaced.
