My Roper washer rtw4640yq1 has always made me wonder if it is doing the right thing. It is less than a year old. It will start to fill, then stop. It sounds like a solenoid is popping something into place and it starts to fill again. This may happen a few times during fill. Is there a temperature sensor? It does several other spooky things I am concerned about, but I thought I would start with these. :-)
