• Due to a block in the hoses.
• Through use of too much or bad toilet paper.
➢ Hint:
1. Fill a plastic bottle (1.5 l) with a strong mix of dish washer
detergent and water. Place the bottle upside down into
the toilet and squeeze it hard to flush the toilet open.
2. Empty a strong mix of dish washer detergent and water
into the toilet bowl and let the mix work for some time.
Pump in water into the bowl and try to flush.
3. Demount the engine in the macerator. Remove the
plastic cover, unscrew the four screws and clean.
Caution: Make sure to place the rubber Simmering/Seal
in the correct place, or the toilet will leak.
❖ Blocked air vents can prevent the emptying of the toilet tank and cause
bad smell:
➢ Hint:
1. Flush some water into the air vents from the outside of
the boat and into the tank. The septic can be dried up and
become “composted”.
2. Fill the septic tank with freshwater and sanitary liquid
through the septic tank vacuum inlet on the deck (the
fitting).
❖ Discharge through the hull fitting/valve is not working correctly

• Macerator pump blocked by non-dissolved paper or non-dissolved
septic.
➢ Hint:
1. Close the bottom valve.
2. Demount the front of the macerator pump. Clean the
plastic “fins” mounted before the pump.
