In hard water areas, limescale is the primary cause of Saniflo failure. Scale builds up on the pressure switch, making the unit "think" it is full when it isn't, leading to constant running or failure to start.
Saniflo toilets use a macerator pump to grind waste and pump it away through small pipes. When these systems clog, they require a different approach than standard gravity-fed toilets. Never use a plunger on a Saniflo, as the pressure can damage the internal seals and motor. unblocking saniflo toilet
If the motor is working but waste isn't moving, the exit pipe is likely clogged. In hard water areas, limescale is the primary
These do not break down and will eventually burn out the motor. When these systems clog, they require a different

Small-diameter pipes (usually 22mm or 32mm) can easily clog with grease or scale.
If the motor smells like burning or the unit continues to vibrate after you have cleared the blades, the internal capacitors or the motor itself may have failed, requiring a professional technician.
