I started seeing this weird problem when I use the lower washer, the drain water (dirty) is going into the top washer. I noticed this suddenly when the whole laundry room was willed with stinky smell, apparently the water was sitting in the top washer for few days. When this happens, I have to run a 19min wash cycle to clean the top washer and this keeps happening every time I use the bottom washer.
Any ideas what is wrong with the machine? Much appreciate any help to fix this issue.
