Wait 30–60 minutes, then press the reset button (on some models) or just let it cool. Fuse / circuit breaker – Check your home’s breaker panel. Faulty float switch – The microswitch inside the tank may be stuck or broken. Requires internal inspection (unplug first). problems with saniflo toilets

Leaking toilet flapper – Water slowly seeps into the Saniflo tank, causing the float to trip the pump. Replace the toilet’s flapper. Stuck microswitch – Tap the control panel gently; if it stops, the switch needs replacing. Non-return valve stuck open – Wastewater flows back from the discharge pipe, refilling the tank. Clean or replace the check valve.
4. Slow Drain or Gurgling Toilet Bowl
Partial blockage in macerator – Small debris (toothbrush cap, cotton ball) passing through. Run a heavy flush of hot (not boiling) water + mild detergent. If persists, open and clean the tank. Venting issue – Saniflo units don’t need traditional venting, but the inlet stack can get clogged. Check the small vent hole on the top of the unit’s lid.
