Hitachi F1 Error Code

High-pressure protection

Causes & Recommended Solutions

The F1 error code indicates a refrigerant pressure issue, typically caused by either high or low refrigerant pressure in the system.

Low Refrigerant Levels

Insufficient refrigerant can cause the pressure to drop, triggering the F1 error.

Blocked Coils or Filters

Dirt or debris buildup on the coils or filters can lead to pressure fluctuations.

Faulty Pressure Sensors

Malfunctioning pressure sensors can provide incorrect readings, leading to system failure.

Check Refrigerant Levels

Make sure the refrigerant is refilled by a professional technician.

Clean the Coils and Filters

Look for signs of refrigerant leaks and have them repaired.

Inspect Pressure Sensors

Have a technician test the pressure sensors for malfunctions.
