Hello,
I have a fairly new LG WM3600 front loader that will often, but not always, leave a little bit of water in the drum after a cycle completes. No error codes, clothes are otherwise spun dry and clean.
One time I was able to watch the water flowing back into the drum, which leads me to believe it is coming back in from the drain hose.
- The standpipe is in a basement, ~60" off the floor.
- It is 18" over the trap
- It isn't overflowing.
- Only a short amount of hose is in the pipe.
- Hose goes straight up to the drain pipe with no kinks.
This made me think there might be a check valve issue, but when I went to the parts diagram for this model I didn't find anything that looked like a check valve / back flow prevention.
Does this washer not have anything like this or am I missing something? Something else I should check before returning it? (no service techs available for weeks...)
Thanks for any help!
