LG's own help library defines OE/E03/E21 as the washing machine being unable to drain the water used during the wash cycle, and names a kinked drain hose or a clogged drain pump filter as the documented causes. LG appliance display · also shown as E03, E21 What to do when OE shows on the appliance ### Kind of code Water supply and drain The new appliance is reporting what it gets from the water connections behind it. A no-water or slow-fill message on the first fill usually means the supply valve is still closed or only half open, or the new line kinked when the unit slid back; a drain message means the drain hose is pinched, pushed too deep into the standpipe, or looped higher or lower than the installation instructions allow. Open the valve fully, straighten the hose, set it to the height the manual gives, and run the cycle again. ### Usually leads to Water supply and shutoff connection New supply lines from a working quarter-turn stop to each water appliance, tested under pressure. ### Shows up as Drain Backing Up After an Install: Plug, Loop and Standpipe A drain backing up after an install leaves water standing in a new machine, pushes it into the sink or spills it over the top of the standpipe. ### Make LG LG installs span refrigerators with water lines, stacked or side-by-side laundry, dishwashers and ranges, often with a Wi-Fi setup at first power-on. ### Source LG USA Support — Front Load Washer Error Code List LG documents OE, E03 and E21 as the same drain error across its current washer platforms. ## Before you book, in this order. Each step comes from LG's own guidance for OE on its appliances. Follow it to the end: the last card says whether this is a visit. 01 Check behind the washer to confirm the drain hose is not kinked or clogged. 02 Clean the drain pump filter, which is a routine step but especially likely to be overlooked right after a new install. 03 Confirm the drain hose height and routing match LG's installation instructions for this model. 04 If OE continues after these checks, book a visit rather than repeating cycles. ### Still there? It usually turns into [water supply and shutoff connection](https://applianceinstallation.center/services/water-supply-and-shutoff-connection/). Book with the code and the model number. ### What not to do OE does not necessarily mean the drain pump itself has failed. LG's own documented causes are a kinked hose and a clogged filter, both of which are checked and cleared without a part. ## What you may notice with it.

Check behind the washer to confirm the drain hose is not kinked or clogged. If it comes back, it needs a visit. ### Is OE likely right after a new laundry machine is installed? Yes, a drain hose bent to fit behind the unit or routed at the wrong height during installation is one of the more common early causes of OE. ### How do I find the drain pump filter to check it? Its location varies by model, so checking the specific installation and use manual for this unit is the documented way to find and access it safely. ### Does OE mean water is backing up into the machine from the house drain? It can be related if the house-side drain connection is not routed correctly, which is why checking the hose height and routing against LG's installation instructions is part of the documented fix. --- **[Read on the site: LG OE — a laundry machine unable to drain](https://applianceinstallation.center/error-codes/lg-oe/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
