What does the OE error code mean and how do I fix it?

The OE error code indicates a drainage problem. Possible solutions include: checking for a clogged, kinked or frozen water drain hose, cleaning the air gap or disposal if clogged, or cleaning the filters if they are clogged. You may also need to feed the drain and water supply hoses through the hole under the sink and gradually slide the dishwasher into the cabinet while pulling on the hoses to take up slack.
