IMPORTANT: Any time you install or remove components, disconnect power to the unit before you begin. "Hot Plugging" components in this manner can cause even further damage to one or more cabinet components.
Check that the valve switch inside the cabinet is not frozen or bound. [Picture]
The electric switch should have detents, but should move freely by hand.
The hydraulic switch should be firm, but still should be able to turn by hand.
If the switch is good, there is a problem with the faceplate, and it must be sent in for reconditioning. Create a UPS Shipping Label HERE.
