FAQ

Question: Why is the drainage pump running but not delivering any water?

Answer:

Most common causes:

  • Discharge valve closed or blocked → Check and open/clean the valve.
  • Nonreturn valve (NRV) blocked → Clean the NRV.
  • Air locked in the pump → Lift pump out of water while running to vent, then lower back in.
