Samsung Heat pump fault E911
Minimum water flow rate not met
Heat pumpWhat it means
Unit stops operation due to insufficient water flow rate. The minimum required water flow rate for operation is 16 liters/min. If flow is below this threshold, the unit will stop and display error E911.
Likely causes
- Water flow rate below 16 liters/min
- Insufficient pump capacity
- Clogged filter or strainer
Where to start
- Verify flow sensor is detecting flow above 16 liters/min minimum
- Verify water flow rate meets minimum 16 liters/min requirement
- Check filter/strainer condition and clean if necessary

Safety: Isolate the outdoor unit and any backup heater, and give the inverter capacitors time to discharge before you open the electrics. Anything on the refrigerant circuit needs F-gas certification.
