What This Part Does

The controller acts as the brain of the toilet system and:

• Activates the macerator pump
• Opens/closes the water solenoid valve
• Manages flush sequence timing
• Performs safety checks on each cycle
• Ensures quiet, smooth, efficient operation

If your toilet is flushing erratically, stopping mid-cycle, or not responding to the wall switch, the controller is often the cause.

• Disconnect power before replacing the board.
• Mounts to the same bracket as the original controller.
• Verify all wiring harness connectors match before powering on.
• Perform a test flush after installation to confirm proper sequencing.
