My LG Dishwasher has an OE error at approximately the 90 minute of the 120 minute wash cycle. Items appear clean.
paulweber1949, generically LG assigned this error code to indicate a problem with the water drain pump. Start by checking the drain hose for kinks or clogs, check the pump for any obstruction inside the housing or for obvious damage. Make sure that if you have a garbage disposal in the same sink line as the drain, that it does not cause any obstructions.since this happens at the end of the cycle, it could be a minor blockage that builds up during the wash cycle.
