It is an Amana front load washer, purchased in Canada. Model #NFW5800DW0. I put that model # in google search and it brings up info. The model # is correct. The hummmmmmmmm noise comes from the pump area at the back. When i unplug it for 10 mins then plug it back in, it just hummmms as though as its trying to drain.
I just had a WFW85HEFC Whirpool front loader with the same issue about 2 months ago, when I unplugged the washer for 10 mins and plugged it back in it would make the same noise. I replaced the water pressure sensor (water level control) and it worked. I am wondering if this is the same issue.....?
