What is IE error code?

Hello there,

My LG front loader washer was also throwing the IE error code -

After cleaning the filters, resetting the machine, changing the inlet hoses - nothing worked… called my appliance repair guy and he spent a total of 30 seconds telling me that the DRAIN HOSE was on the floor and not elevated above the drain pump… one ZipTie later attaching the drain hose to the inlet hose and BAM, the most expensive ZipTie EVER!!

Works like new now - save yourself some money and check that your drain hose is not on the floor, but elevated above the level of the drain pump (about halfway up the machine)…

Evidently GRAVITY is the “valve” that keeps the water in the tub and avoids the IE error code…

Since the pressure switch and inlet components have already been replaced, I’d avoid replacing more parts until the installation and water path are checked. Make sure both supply taps are fully open, the inlet screens and hoses are clear, and the drain hose is installed at the correct height so the washer cannot siphon water out while filling.

If water is entering normally but IE still returns, the wiring/connectors between the inlet system, level sensing system and control board are worth checking.

I put the LG IE troubleshooting sequence together here:
