Answers to Common Questions
View All FAQsWhy Is My Water Heater Not Heating Up Despite Resetting the Button?
Resetting the button usually won’t fix the root problem. If your water heater still isn’t heating, the issue may be a failed heating element or thermostat, a tripped breaker or gas supply problem, or sediment buildup. We diagnose and repair gas, electric, tank, tankless, and heat pump units with same-day/next-day service and 24/7 emergency response. Flush tank-style heaters annually. Schedule annual professional maintenance for tankless and heat pump models to reduce shutdowns.
Quick checks:
- Confirm the breaker is on or the gas valve is open.
- Verify cold-water supply is on.
- Note any error lights/codes for the technician. <br/>

A water heater that has power but no hot water is most often caused by a failed heating element or a faulty thermostat/control. On electric units, the high-limit safety switch can trip when an element burns out, stopping heat even though the unit has power. Gas models can have power to the control board but still fail to heat if ignition components or gas supply are compromised. In our Massachusetts service area, we frequently trace no-heat calls to a burned upper element or a miswired replacement thermostat. A quick meter test at the element terminals confirms the fault faster than guesswork.
Try these focused checks next:
- Press the water heater’s reset button and confirm the breaker is fully seated.
- For electric: test element continuity and replace any failed element; verify thermostat calibration.
- For gas: confirm burner ignition, flame sensor/thermocouple function, and unobstructed venting.
- If the tank rumbles or heats slowly, plan a sediment flush.
If you smell gas or find active leaks, shut off utilities and contact a licensed technician immediately. <br/> Updated: 2026-04-01 <br/> Need help in Southborough, MA?

If water is leaking from the bottom, shut off the cold-water supply and power, then request emergency service. A bottom leak can signal internal tank damage, and replacement is often the practical fix. Endless Energy offers 24/7 emergency response and same-day replacement for urgent failures. We service homeowners across Newton and Worcester.
Quick steps:
- Turn off power: switch off breaker (electric) or set gas to “pilot.”
- Close the cold-water valve to the heater.
- Place a pan or towels to contain water.
- Do not delay; schedule service to prevent damage.

You can,
No, not in most cases, this is why we recommend professional installation for a safe, correct setup. Our in-house certified technicians install tank, tankless, and heat pump units with same-day or next-day service and 24/7 emergency support. For tankless and heat pump water heaters, leave installation and annual maintenance to professionals for best performance. Installations include a stated 1-year labor warranty, and many models have manufacturer warranty options up to about 10 years. Financing, 0% options, and rebate assistance are available.
