LG WM3570H front load washer drain pump filter leaks after cleaning

[khhale]

Using the manual, I drained the water, then unplugged the drain pump filter, cleaned it out, and screwed drain pump filter back in.

I had done this before, with no problems. There were no error messages; just seemed like a good idea.  

I started a load, then discovered my kitchen was flooded--water was pouring out of drain front filter (lower left corner of washer)

I removed the load, reinserted the drain pump filter, once again turned as tight as possible.  Started with empty load.  Water continues to pour out of filter.  

Looked at more guidelines from LG and youtube--there are no clues there.  This isn't supposed to happen.

I tried again--water still pours out of drain pump filter plug, as if it's not screwed in tight. I've screwed it in as tight as possible short of using a metal wrench on this plastic fitting.

Any help appreciated...I'm afraid to try simple teflon tape because this isn't a small leak - water pours out around all the threads.

Remove the filter trap again and with a small screwdriver carefully clean out the threads in the pump body and the filter trap.

Make sure the rubber trap seal is still in place.

I've had this happen once and it was sand/grit that was trapped in the threads - it felt like it tightened down all the way but it leaked.   After removing and cleaning the grit out of the threads and reinstalling all was fine.

Usually what i see too. 

I use a shop vac to suck on the threads to get them clean. A nylon brush can help jar it loose and then the vac suck it away.

If your unlucky and have some nicks in the oring use light coat silicone sealant to fill the nicks after cleaning.
