To reset a Titan water heater, locate the reset button on the thermostat, usually found behind the access panel, press it firmly, and ensure the power is restored to the unit for proper operation.
Resetting your Titan water heater can solve common issues like temperature fluctuations or system failures. This guide provides step-by-step instructions while explaining safety precautions and troubleshooting tips.
When to Reset Your Titan Water Heater
Only reset your Titan water heater when:
- The green LED light is off
- The display shows no information (on larger units)
- You experience sudden temperature changes
- The unit stops producing hot water completely
If your unit has power but isn’t heating properly, check our guide on water heater error lights first.
Safety Precautions Before Resetting
Power Down Properly
Always turn off the power at the circuit breaker before working on your water heater. For gas models, turn off the gas supply valve.
Water Temperature Warning
Hot water can cause severe burns. Allow the system to cool for at least 30 minutes before attempting any reset procedure.
Pressure Release
According to Titan’s technical documentation, you must drain the tank before resetting to prevent pressure buildup.
Step-by-Step Reset Process
1. Power Down the Unit
Locate your home’s circuit breaker panel and switch off power to the water heater. For gas models, turn the gas control valve to “off.”
2. Drain the Water Heater
- Connect a garden hose to the drain valve
- Open a hot water faucet in your home
- Open the drain valve and let water flow until empty
3. Locate the Reset Button
The reset button is typically:
- Behind the access panel on electric models
- Near the thermostat on gas models
- Clearly marked as “Reset” or with a circular arrow symbol
4. Press and Hold the Reset Button
Press firmly for 5-10 seconds. You may hear a click when the system resets.
5. Refill and Restart
- Close the drain valve
- Turn on a hot water faucet in your home
- Slowly open the cold water supply valve
- Wait until water flows steadily from the open faucet
- Restore power at the circuit breaker
Common Issues After Reset
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | Air in system | Run faucets for 5 minutes |

Maintenance Tips to Avoid Frequent Resets
- Descale annually in hard water areas

- Flush the system every 6 months
- Monitor water pressure (should be 40-80 psi)
According to Titan’s troubleshooting guide, most reset issues stem from mineral buildup or electrical surges.
