If your hot water has unexpectedly stopped, don’t worry—there are several steps you can take to restore it. By identifying the issue and following the right procedures, you can often solve the problem without needing professional help.
How to Turn Your Hot Water Back On
To switch your hot water back on, first identify the type of water heater you have: electric, gas, or tankless. Each type requires different steps to restore hot water.
Electric Water Heater: Troubleshooting Steps
- Check the Power Supply: Ensure the water heater is plugged in and the circuit breaker hasn’t tripped. If the breaker is off, reset it.
- Inspect the Thermostat: Set the thermostat to at least 120°F. If the temperature is too low, adjust it to the desired level.
- Examine the Heating Elements: If the water remains cold, the heating elements might need replacement. This requires turning off the power and checking for continuity with a multimeter.
Gas Water Heater: Getting the Heat Back
- Verify the Gas Supply: Ensure the gas valve is open. If you smell gas, leave the area and contact your gas company immediately.
- Relight the Pilot Light: If the pilot light is out, follow the manufacturer’s instructions to relight it. Typically, this involves turning the control knob to "pilot" and using a lighter or igniter.
- Check the Thermocouple: If the pilot light won’t stay lit, the thermocouple might be faulty and require replacement.
Tankless Water Heater: Quick Fixes
- Inspect the Power Source: Ensure the unit is connected to power and the breaker is not tripped.
- Clean the Inlet Filter: A clogged filter can reduce performance. Clean or replace it as needed.
- Review Error Codes: Consult the manual for any error codes displayed and follow the recommended troubleshooting steps.
When to Call a Professional
If these steps do not restore your hot water, it may be time to call a professional plumber. They can diagnose and fix more complex issues, such as faulty wiring or gas leaks.
Common Reasons for Hot Water Issues
Understanding why your hot water stopped can help prevent future issues. Here are some common causes:
- Tripped Circuit Breaker: Often caused by a power surge or faulty wiring.
- Pilot Light Outage: Can occur due to drafts or a faulty thermocouple.
- Sediment Buildup: Reduces efficiency and heating capability in tank water heaters.
- Faulty Heating Element: A common issue in electric water heaters.
- Gas Supply Problems: Could be due to a closed valve or gas line issues.
