Error Code 24 on your Rheem Continuous Flow Water Heater indicates an “Operational Switch Fault.” This usually means there is an issue with the operational or safety switches inside the unit, preventing it from functioning normally.
For your safety, immediately turn off the power supply at the isolation switch and ensure all hot water taps are closed. Internal operational switch faults require a professional technician to diagnose and resolve safely. Contact Hilton Plumbing promptly for an expert inspection and repair.
