Water heater repair

Rarely an emergency

No hot water is usually the heat source — a tripped breaker or high-limit switch, or a pilot that went out. Water around the tank is urgent: shut the cold supply and the power or gas, then find where it is coming from.

Water heater leaking waterUsually urgent, not an emergency

Is it an emergency? Usually urgent, not an emergency. Turn off the water to it and switch off its breaker, then soak up standing water. If water is reaching outlets or cords, switch off the breaker before touching anything; water coming through a ceiling is an emergency.

Water heater making a loud noiseUsually not an emergency

Is it an emergency? Usually not an emergency. A new grinding, rattling or humming most often comes from a fan, motor, belt or loose panel. Stop using it and cut the power if the noise comes with a burning smell, smoke or sparks; if it runs on gas and you smell gas, leave and call the gas company or 911 from outside.

Water heater flashing an error codeUsually not an emergency

Is it an emergency? Usually not an emergency — the code is the appliance reporting a fault it detected. Note the code, then turn it off at the breaker for a minute and back on. If the code returns with a burning smell, smoke or a leak, leave it off and call a pro.
