If you discover your macerator is not functioning correctly, first check to see if the impeller is stuck. A stuck impeller can be easily broken loose with a screwdriver inserted in the motor shaft slot.
- Remove the rubber boot
- Turn the shaft clockwise
- Replace the rubber boot.
The impeller can usually be found under the touring coach, near the macerator hose reel.
If the electric dump valves fail to open, a manual pull/push arm is available to use under the vehicle.
- Do not run the Macerator pump for more than 15 minutes continuously.
- Do not run the Macerator pump dry for more than 30 seconds.
THE MACERATOR WILL NOT HANDLE HARD SOLID OBJECTS, SANITARY NAPKINS, OR RAGS. Never put wet strength paper towels, tissues, or sanitary napkins in your holding tank. They will not dissolve and will jam the mechanism of the dump valve and the macerator pump impeller.
If you have further problems, please contact your local dealership or service center.
