A friend gave me a Kenmore Elite Calypso (Model #22062102) washing machine. However it flashes LS (or L5) when I try to start machine and will not let me start any type of cycle. There is no visible Lid Switch, but I can hear a very slight clicking sound near the right back side when raising and lowering the lid. I have unplugged the machine for 30 minutes, and even tried putting pressure on different areas of the lid. Any suggestions on how to fix this, or do I need to call Sears?
