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

If your water heater won’t heat after pressing reset, a persistent fault is likely. Common causes include a tripped breaker, failed heating element or thermostat (electric), pilot/ignition or gas supply issues (gas), or sediment buildup reducing heat transfer. Tankless units may stop heating from low flow or a clogged inlet filter. Annual professional tune-ups help prevent these issues. We service conventional, tankless, heat-pump, and indirect systems in Scranton and nearby NEPA.

Quick checks:

• Verify breaker and power switch are on.
• Confirm gas valve and pilot/igniter.
• Open a hot tap fully for tankless.
• Flush sediment if overdue.
• If you smell gas or see leaks, stop and call. <br/>
