What to Do When You Suddenly Have No Hot Water

There is no greater frustration than turning the faucet or showerhead on in an attempt to find hot water, only to find that there is none. Whatever you were trying to do, such as taking a shower, washing dishes, or doing laundry, the lack of hot water could bring your activities to an abrupt halt.

Homeowners in Melbourne who are facing a lack of hot water will have to understand the possible reasons behind it to know how to go about fixing their problem. Some problems can be fixed through troubleshooting procedures, but other hot water problems need to be taken seriously before further damage occurs.

In this article, we will examine what you should do if your hot water fails, the different types of problems that lead to a lack of hot water, and determine when you need to call a professional for a hot water emergency repair in Melbourne.

Why Has My Hot Water Suddenly Stopped Working?

Some reasons why your hot water has stopped might include- 

  • Lack of power
  • Lack of gas
  • Thermostat malfunction
  • Heating element failure
  • Pilot light failure
  • Leaky water system
  • Sediment build-up
  • Old appliances

Step 1: Take a Breath and Test All Other Taps

Do not make the mistake of assuming that your whole hot water system is down before checking other taps.

Think about these questions:

  • Is there no hot water from any tap?
  • Does the hot water problem affect a specific bathroom or kitchen?
  • Is there water flowing, but cold?

The hot water problem might just be affecting a single tap or the piping leading up to it, rather than your whole hot water supply system.

Step 2: Check Your Power Source

Electric hot water systems will almost always lose power when they are suddenly unable to provide hot water.

Things to Check:

  • Circuit Breakers
  • Safety Switches
  • Power Outage
  • Connections with Electricity

If you find that your circuit breaker has tripped, try to reset it again, but do not keep resetting it. It may mean that there is an electrical problem with your hot water system.

Step 3: Check the Gas Supply

If your property utilizes gas for your hot water system, ensure that gas is supplied to the water heating system.

Gas supply problems include:

  • The pilot light is going off
  • Other gas-powered appliances are failing to function
  • Gas Meter Problems

Step 4: Check the Pilot Light

Many older hot water systems depend on a continuous flame of the pilot light.

In case the pilot light flame goes off:

  • Follow the directions to relight it as instructed by the manufacturer. 
  • Make sure there is sufficient ventilation. 
  • Avoid forced ignition in the event of a gas smell.
  • Continuous pilot light failure requires professional servicing. 

Such a situation may be considered a hot water emergency since it indicates other problems with your hot water system.

Step 5: Review Thermostat Settings

The thermostat regulates water temperature in your hot water system.

Problems can arise in the following scenarios:

  • Incorrect adjustment of the thermostat
  • Faulty functioning of the thermostat
  • Too low a temperature setting

Typically, most domestic hot water systems work properly at temperatures ranging from 60° to 65° Celsius. If resetting does not help fix your hot water problems, it means that the thermostat should be replaced.

Step 6: Investigate Potential Leaks

Leaking can adversely affect the efficiency of your hot water system.

Check if there is any sign of leakage in the hot water unit:

  • Presence of puddles
  • Rust spots
  • Corrosion signs
  • Dripping valves
  • Water-soaked insulation

Leakage in the hot water tank may indicate a more serious issue requiring hot water system replacement.
