LG front loader drainage

[Paul2020]

Hi all - I have a LG front loader - about 7 years old. It started giving the OE error indicating a problem with drainage. I checked the filter and drainage hose - both were ok. I manually drained the water and continued the cycle - no further problems. 
 

During the next load the same problem occurred. I rechecked the filter and drainage hose - again both were ok. So I removed the drainage pump and bench checked it - it seemed to work fine. I reinstalled the pump and for the next two loads had no problem, but on the third the same OE error occurred. 
 

Any thoughts on what the cause could be? What should I check next?

Cheers

Paul.

Sorry for a late reply. It may be fixed by now. But if a washing machine is giving a draining error don't believe it unless you can see that the washing machine is definitely not draining. The device for detecting if the water has drained out or not (the pressure system) can go faulty or become blocked and report a drain error when there isn't one. If so you can't fix it looking at the pump. So when it stops with the drain error - is it full of water or has it pumped away OK?
