Scott Johnson Posted July 26, 2021 Share Posted July 26, 2021 The auto drain valve on our 2021 LE II is not working. It's not actually the drain valve but is used to prevent the gray tank from sloshing up into the shower pan while driving. The switch is in the closet. The light does not go on and the valve motor / mechanism does not engage. Oliver service said that if the light doesn't turn on, it probably doesn't have power to the switch. I checked and that is the case. The manual and the documentation from the manufacturer (Barker) says there is an inline fuse. Does anyone know where that fuse is located? I don't believe it is in the wiring inside the closet as I've carefully pried apart the flex tube and don't see or feel anything other than wires. The wires and tube go into the inner wall and, I assume, under the bathroom sink. Also, in removing the switch to check for power, I inadvertently disconnected the wiring at the rocker switch. I'll have to get a wiring diagram from service or Barker unless someone has experience and can help to determine which wires connect to which terminals.
