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

Resetting the button but still getting no hot water usually means another fault. Common causes include a tripped breaker, failed heating element or thermostat (tank units), pilot or gas supply issues (gas units), tankless error-code lockout, or scale buildup. We handle no-hot-water calls, error messages, and temperature swings, and we recommend annual flushing/descaling for tankless systems to prevent mineral buildup.

Quick checks:

• Check the electrical breaker or power switch.
• Verify gas is on and relight the pilot if needed.
• Note any error codes on tankless units.
• Look for leaks or pooling water.
