Troubleshooting Your Water Heater in London, Ontario
There's nothing worse than turning on the tap for a warm shower and getting an icy blast instead. If you have no hot water, it's a major disruption. Before you worry, Hawana HVAC has a list of common issues that London homeowners face, from simple fixes to problems requiring professional water heater repair.
1. The Pilot Light is Out (Gas Heaters)
For conventional gas water heaters, the pilot light is a small, continuously burning flame that ignites the main burner when needed. If it goes out, your water won't heat up. You can often see the flame through a small window at the bottom of the tank.
- What to do: The instructions for relighting are usually on a label on the tank. However, if you are not comfortable doing this, or if you smell gas, DO NOT proceed.
- Safety First: If you smell gas, leave your home immediately and call your gas utility (e.g., Enbridge). If the pilot light won't stay lit after relighting, it's a sign of a deeper issue like a faulty thermocouple, and you need a TSSA-certified technician.
2. Tripped Circuit Breaker (Electric Heaters)
If you have an electric water heater, the solution could be as simple as a tripped breaker. Electric heaters use a lot of power and are often on a dedicated circuit.
- What to do: Find your home's electrical panel. Look for a double-pole breaker labeled "Water Heater" or similar. If it's in the 'off' position or in the middle, switch it completely off and then back on again.
- When to Call Us: If the breaker trips again immediately, there's an electrical fault within the heater, like a bad heating element or thermostat. Do not keep resetting it. Call for professional service in London or St. Thomas.
3. Faulty Thermocouple or Gas Control Valve
The thermocouple is a safety device that shuts off the gas if the pilot light goes out. When it fails, it will shut off the gas even if the pilot is lit, preventing the burner from igniting. This is one of the most common reasons for a pilot light that won't stay lit. This repair is not a DIY job and requires a licensed professional.
4. A Leaking Water Tank
Puddles or water stains around your water heater are a serious warning sign. While a leak could come from a fitting, it often indicates corrosion and internal failure of the tank itself. A leaking tank cannot be repaired and is at risk of bursting, causing major water damage.
Action: If you see water pooling, immediately shut off the water supply to the tank and call for emergency water heater repair in London, ON. Our team is ready to respond quickly in areas from Dorchester to Port Stanley.
