Hot Water Tank Not Working Greater Vancouver

A hot water tank that stops working in a Greater Vancouver home is one of the most disruptive household failures. Most causes are diagnosable quickly with a few checks.

What This Means

Hot water tanks can fail to heat from a pilot light outage (gas), a tripped breaker or failed element (electric), or a control fault. Identifying the energy source narrows the diagnosis immediately.

Common Causes

• Gas tank: pilot light out, thermocouple failed, gas valve fault
• Gas tank: no gas supply to the unit
• Electric tank: circuit breaker tripped, upper heating element failed
• Electric tank: thermostat stuck or failed
• Both types: sediment buildup reducing heating efficiency over years

What Homeowners Can Check Safely

• Gas: check whether the pilot light is lit through the inspection window
• Gas: check that other gas appliances work (confirms gas supply is fine)
• Electric: check the circuit breaker for the water heater — a tripped breaker is a common cause

When to Call a Licensed Technician

Water heater work involves gas lines, high-voltage wiring, and pressurized plumbing. Always call a licensed gas fitter or plumber for repairs beyond basic visual checks.

• Thermocouple replacement on gas units
• Gas valve testing and replacement
• Heating element testing and replacement on electric units
• Anode rod inspection and replacement

Frequently Asked Questions

My hot water tank stopped working overnight. Is it the pilot light?

A pilot light outage is the most common cause of a sudden gas water heater failure. Look through the small inspection window — if no flame is visible, the pilot is out. The unit label includes relighting instructions. If the pilot relights but goes out again within minutes, the thermocouple is likely the cause.

My electric water heater is not producing hot water but the breaker is fine. What else could it be?

With the breaker confirmed on, the next likely causes are: (1) upper heating element failed — the upper element heats the top portion of the tank and must work for any hot water to be available; (2) upper thermostat failed and needs reset (there is a reset button behind the upper access panel); (3) lower element failed — you would get some hot water briefly before it runs cold.
