The 1E and/or OE codes indicate a draining problem, which usually occurs due to a blockage or drain pump failure. In most cases, cleaning filters and the sump solves the problem. However, if these do not work, a more serious procedure is required.

Filter and Sump Thing

1. Open the door and check the filter at the bottom of the cavity.
2. Turn the filter counterclockwise by the handle to access the filter compartment.
3. Take off the filter door.
4. Remove the flat micro filter underneath.
5. Clean the filter door and micro filter and rinse them out properly.
6. Check the sump, which is located at the bottom of the drain compartment and remove any gunk or debris.
7. Put the flat micro filter and filter door back and turn the filter door clockwise by the handle to lock the filter.
