What Does Error F03 Mean?
The GE water heater F03 error code indicates a compressor failure in GeoSpring or heat pump models. This fault occurs when the control unit attempts to energize the compressor but detects no current flow, resulting in a lack of hot water and potential beeping sounds. Users may notice the unit reverting to resistance heating or failing to heat altogether.
Common Symptoms:
- Display shows F3 error code
- Water heater fails to heat via heat pump (no compressor activity)
- Beeping accompanied by F3
- Unit may revert to resistance heating or no hot water
Possible Causes
- Compressor electrical failure or no current detected (high)
