How do you reset a water heater when it stops working?

Question

Accepted Answer

To reset a water heater that stopped working, perform a safe reset only after confirming power or gas supply and checking for leaks or burning smells. Most shutdowns come from a tripped safety limit (electric) or an extinguished pilot/lockout (gas), often triggered by overheating or scale. In our hard‑water region, sediment can cause hot spots that trip the high‑limit, so a reset may be a short‑term fix rather than a cure. Our licensed plumbers handle full water‑heater service across the West Valley and regularly resolve resets that point to deeper issues. Try these steps carefully: - Electric: Switch off the breaker, remove the upper panel, press the red reset on the thermostat, replace the panel, then restore power. - Gas: Turn the control to Off, wait 5 minutes, then follow the lighting instructions on the unit and set to normal. - Stop immediately if the reset trips again, the burner won’t stay lit, or you smell gas. If the unit keeps tripping or won’t relight, schedule service to prevent damage or scald risk.
