Control Module

The door panel must be removed to access the control module. (See Door Panel.) The main control is considered a “smart” control, capable of learning the water temperature and turbidity characteristics of the home.

It is normal for the cycle times to vary over a period of time from the factory default settings due to temperature and water quality.

The control module is held in place by a single screw that secures the module to the right side of the inner door panel. (The screw is located on the outside of the inner door panel.)

The module cover is held in place by 5 tabs (see arrows).
