The washer pumps all the water out on the spin cycle and if clothing is immediately removed there is no problem.
After a period of time, I will find standing water in the drum. I don't think it can siphon back from the drain line but maybe. I'm wondering if the water fill valve may be leaking by.
This sounds more like an issue of the water valve allowing the water to flow through even though the unit is not calling for water. You will want to pull the hoses and check the screens on the water valve to make sure that there is no debris in them. If there is clean them out and recheck to see if water is still trickling in. If there is then the water valve 134190200 would need to be replaced.
