No Hot Water? It Might Be an Electrical Problem

There's nothing quite like stepping into the shower, expecting a nice hot one, and getting blasted with freezing cold water instead. Now, we know Uncle Macca swears by his morning cold plunges, but some of us prefer to ease into the day without going into survival mode.

Before you start blaming the kids for using all the hot water, or assume the whole system has packed it in, there might be another explanation. Your hot water system could have an electrical fault.

And the good news? It doesn't necessarily mean you need a whole new system.

At Cowley Electrical Services, we help homeowners, businesses and property managers across Moruya, Batemans Bay and Eurobodalla with electrical faults, including those affecting electric hot water systems.

Here's what might be going on, what you can safely check yourself and when it's time to call a sparky.

Why Has My Electric Hot Water Stopped Working?

An electric hot water system relies on several components working together. When one stops doing its job, you might end up with lukewarm water, no hot water at all, or a system that keeps tripping the power.

Some of the common electrical culprits include:

1. A Tripped Circuit Breaker or Safety Switch

Your hot water system may have its own circuit in the switchboard. If the circuit breaker or safety switch trips, the system loses power and stops heating.

What can you check?

Have a look at your switchboard for a switch labelled 'Hot Water' or 'HWS'.

If it's tripped, don't keep resetting it. A circuit that repeatedly trips can indicate an electrical fault that needs investigating.

Uncle Macca might reckon the switch just needs a bit of encouragement, but repeatedly flicking it back on isn't going to fix a faulty circuit.

If you notice burning smells, heat, damage or signs of water getting into electrical equipment, leave it alone and call an electrician.

2. A Faulty Heating Element

Inside a conventional electric storage hot water system is a heating element that heats the water. Over time, elements can fail.

You might notice:

  • No hot water, even after allowing enough time for the tank to heat.

  • Water that never seems to get properly hot.

  • A hot water circuit that trips.

  • Hot water that suddenly runs out much faster than usual.

A licensed electrician can test the electrical components to determine whether the element is the problem.

And the good news? A failed element doesn't automatically mean you need to replace the entire hot water system.

3. A Faulty Thermostat

The thermostat controls when the heating element switches on and off. If it fails, the system may stop heating or struggle to maintain the correct temperature.

This is another fault that needs proper testing rather than guesswork.

4. An Off-Peak Power Supply Issue

Some electric storage hot water systems run on a controlled-load tariff, commonly called off-peak power. These systems may only receive electricity during certain hours.

If your system uses controlled-load power, the problem could involve the supply, switching equipment or metering arrangements rather than the hot water unit itself.

An electrician can help determine whether the issue is within your installation or needs to be referred to your electricity retailer or network provider.

5. It Might Not Be Electrical at All

Not every hot water problem is one for the sparky. Leaks, faulty valves, water pressure issues and problems with the tank itself may need a plumber.

If you have a heat pump or gas hot water system, the diagnosis can be different again.

The trick is working out which trade you need before you spend money replacing something that isn't actually broken.

What Can You Check Before Calling an Electrician?

A few simple observations can help narrow things down.

Check whether it's the whole house. Is every hot tap cold, or is the problem limited to one shower or tap? If it's only one outlet, the issue may be with the plumbing fixture rather than the hot water system.

Check your switchboard visually. Look for a tripped circuit breaker or safety switch, but don't remove covers or touch wiring.

Think about when the problem started. Did the hot water stop after a storm, power outage or electrical work? Has it been getting progressively worse?

Check for obvious leaks. If water is leaking from the tank or fittings, contact a plumber. Keep clear of wet electrical equipment.

And please, don't start pulling covers off the hot water system to investigate. We know Uncle Macca has a shed full of tools and a YouTube degree in just about everything, but electrical repairs aren't a weekend DIY project.

Should You Repair or Replace Your Hot Water System?

That depends on the age and condition of the unit, the type of fault and the cost of repair. If the tank is in good condition and the problem is an electrical component, repairing it may be a sensible option. If the tank is leaking, badly corroded or nearing the end of its useful life, replacement may make more sense.

It's also worth considering whether a heat pump hot water system could suit your home, particularly if you're looking at ways to reduce electricity consumption.

The important thing is to diagnose the fault first.
