Why Replace the Flush Control Module?

The control module serves as the "brain" of the MasterFlush toilet system. It receives input from the flush pedal and sensors while controlling operation of the:

• Macerator motor
• Water valve
• Flush sequence timing
• Tank monitoring functions

When the control module fails, the toilet may stop functioning altogether even though other components remain operational. Replacing the module is often one of the most effective repairs for a non-functioning Dometic 7640 toilet.
