Why Isn’t My Water Heater Working?

There’s nothing quite like the comfort of a warm shower after a long day until you turn the knob and only cold water greets you. Water heater problems can be a disruption and an inconvenience, but rest assured, we’re here to help.

With over 90 years of experience, our team of NATE-certified technicians can diagnose and solve your water heater issues, ensuring you can go back to enjoying your warm showers in no time. If you’re looking to get to the bottom of your water heater troubles, here are some common reasons why your water heater is not heating.

No Power or Gas

Depending on whether you have an electric or gas water heater, the problem could stem from a power or gas supply issue. Make sure your breaker hasn’t tripped for electric heaters or that the gas valve is open for gas heaters. However, if power or gas supply is not the issue, it might be something more serious that requires professional attention.

Thermostat Issues

Your water heater’s thermostat could be the culprit behind the cold showers. If the thermostat is set too low or malfunctioning, it won’t send the right signals to heat the water. You can try adjusting the temperature settings, but the thermostat may need to be replaced if that doesn’t work.

Pilot Light Problems

For gas water heaters, the pilot light ignites the gas burner that heats the water. If this light goes out or has trouble staying lit, your water heater won’t function properly. A faulty thermocouple or dirty vent could be causing these pilot light issues.

Low Water Pressure

Low water pressure can also lead to water heating issues. If there’s a blockage or leak in your system, it can impact the water pressure. While handy homeowners can fix some causes of low water pressure, others might be more complicated and require the help of a professional plumber.

Top notch install quality. While my ac wasn’t that old, I opted for a higher efficiency heat pump system and replace my worn-out older furnace! The difference in my home is night and day difference, can’t wait to see what the bills do.
