Why Is My Water Heater Not Heating Up Despite Resetting the Button?

If your water heater still won’t heat after pressing reset, an underlying fault is likely. Common issues include a failed thermostat or element, a tripped breaker or gas supply problem, or heavy sediment that insulates the tank. Annual flushing prevents sediment buildup, and tankless units need descaling. If repair costs exceed half the price of a new unit, consider replacement (the 50% rule). We provide 24/7 water heater diagnostics, repair, and replacement in Dayton and nearby areas.

Quick checks:

• Check the breaker or gas supply.
• Verify thermostat settings.
• Look for leaks or error codes.
• Note unit age and last maintenance.
