Common Causes of Error Code 17
Error code 17 in Rheem tankless water heaters typically signals an ignition problem. Understanding the common causes can help you troubleshoot effectively.
Lack of Water Flow
Lack of water flow can trigger error code 17. If water isn’t circulating properly, the heater may not ignite. Check for obstructions in pipes or valves. Make sure the water supply is turned on. Regularly clean filters to prevent buildup that obstructs flow.
Overheating Issues
Overheating can also lead to this error. If the heater’s temperature exceeds safety limits, it may shut down. Check the thermostat settings and ensure they aren’t set too high. Inspect the heat exchanger for sediment buildup that can impair efficiency. Flushing the unit can help maintain optimal performance.
Electrical Problems
Electrical issues can cause the ignition failure associated with error code 17. Loose connections or damaged wiring affect the heater’s performance. Inspect the wiring for any signs of wear or corrosion. Ensure the power supply is stable and properly connected. If problems persist, consult a technician for further assistance.
