What to Do When Your Water Heater Stops Working

There’s nothing quite as frustrating as stepping into the shower, only to be met with an unexpected blast of icy water. If your water heater has stopped working, it can throw your entire routine into chaos. Fortunately, there are a few troubleshooting steps you can take before calling in a professional.

Check the Power Source

The first thing to determine is whether your water heater is getting power.

• Electric Water Heaters – Check your switchboard to see if a circuit breaker has tripped. If it has, reset it and test the water again in about 30 minutes.
• Gas Water Heaters – Ensure the pilot light is still lit. If it has gone out, follow the manufacturer’s instructions to relight it safely.

Inspect the Thermostat Settings

If your water heater is on but not producing hot water, it’s worth checking the thermostat. Sometimes, it can be accidentally adjusted to a lower setting. Most systems should be set to around 60°C for optimal performance and safety.

Look for Water Leaks

A leak in your hot water system could be the reason you’re experiencing inconsistent temperatures or no hot water at all. Check around the base of the unit for pooling water or signs of corrosion. If you find a leak, turn off the water supply and contact a plumber immediately.

Test Different Fixtures

If your shower is not getting hot water but the sink is, this could indicate a specific issue with your shower’s plumbing rather than the entire water heater. A faulty shower valve, sediment buildup, or a pressure imbalance could be the culprit. In such cases, a plumber may need to inspect the shower’s internal components.

Flush the Tank

Over time, sediment can build up in your water heater, reducing its efficiency and blocking heat transfer. Flushing the tank once a year can help prevent this issue. If you haven’t done this before, a licensed plumber can assist.

Consider the Age of Your Water Heater

Most hot water systems have a lifespan of around 8–15 years. If your unit is reaching the end of its expected life and frequently breaking down, replacement might be the best option. Newer models are more energy-efficient, saving you money on bills in the long run.

Call a Professional Plumber

If you’ve checked everything and your water heater still isn’t working, it’s time to call in an expert. A licensed plumber can diagnose the problem and provide solutions, whether it’s a repair, part replacement, or a full system upgrade.

Ready to get started?

A broken water heater is a major inconvenience, but with some basic troubleshooting, you may be able to resolve the issue or at least identify the cause before calling a professional. Regular maintenance, including flushing the tank and checking the thermostat, can help prevent sudden failures and keep your hot water system running efficiently. If you’re still experiencing problems with your water heater, it’s always best to seek expert advice to ensure your system is safe, reliable, and functioning correctly.
