Check that the water heater has energy supply, is not in safety lockout, and that basic settings are correct. The most common cause of no hot water is a power or fuel interruption after maintenance or weather. Set the thermostat near 120 F and make sure any tankless display shows a normal temperature, not vacation or an error. On many electric units, the high‑limit switch trips after a dry start or overheating and needs a manual reset once the root cause is fixed. Our technicians see these issues often and can resolve them efficiently in the Ferris area.
Look for these quick signals before you call:
- Electrical supply: check the breaker, fuse, or GFCI outlet.
- Gas supply: confirm the gas valve is open and the pilot/igniter works; only relight if you know the steps.
- Water and controls: verify the cold inlet valve is open and check for error codes on tankless displays.
Stop and call a licensed pro at once if you smell gas, see active leaking, or hear sizzling from an electric unit.
