The AE or E1 error code indicates a possible leak from the unit. This is most often caused by excessive suds overflowing into the base of the dishwasher.
This problem could be caused by a failure on your machine or the detergent used. I highly recommend you follow the troubleshooting from the LG website. HEre is the link.

Hi there Romey. The error code OE relates to the drainage system, there are some things you can check to helpdiagnose the fault. you can check the filter in the bottom of the dishawaher isnt cloghed up or blocked. While you hae got the filter out have a look for any signs of large debrit that may cause a blockage. If all of this is ok you will need to check the waste pumps operational condition. make sure the pump impellar hasnt come loose/broken off or become jamed up.
If you cannot find any fault wit any of these things you may need to replace the control board. please let me know if there is anything else I can do to asist you with this issue.
Regards Gary
