Common Hot Water System Faults We Fix
At Cyber Plumbers, our qualified plumbers and licensed gas fitters have the know-how to troubleshoot and repair any type of hot water system. Using the latest diagnostic techniques, we ensure no fault goes undetected.
From electric and gas to solar and heat pump units, each system type has its own quirks and potential faults. That’s why you need an experienced hot water professional who can pinpoint and fix the exact cause of your supply problems.
Gas Hot Water Systems
Gas units can develop issues such as:
- Pilot light, ignition or thermocouple failure
- Gas supply faults, including faulty or shut valves
- Thermostat or flow sensor malfunction
- Blocked or restricted gas lines
These faults can cause no hot water, unpleasant odours, discoloured water or leaks. Continuous flow systems may also produce fluctuating temperatures, show error codes or shut down entirely.
Electric Hot Water Systems
Common electric hot water unit problems include:
- Heating element failure
- Tripped breaker or wiring issues
- Thermostat malfunction
- Broken dip tube
In storage models, sediment build-up may cause reduced capacity, bad smells, discolouration or noisy operation. Corrosion or faulty valves can lead to tank leaks.
Solar Hot Water Systems
Typical solar HWS faults include:
- Damaged or inefficient solar collectors
- Pump or circulation failures
- Defective sensors
- Overheating or freezing from poor antifreeze protection or temperature control
Many solar setups have an electric or gas booster, which can also require repair during low-sunlight periods.
Heat Pump Hot Water Systems
Possible heat pump HWS issues include:
- Compressor problems
- Faulty electrical connections
- Low refrigerant levels
- Plumbing leaks
Whatever the system or fault, Cyber Plumbers will find the cause and fix it. With same-day service and rapid response times – often within the hour* – we’ll have your hot water back on without delay.
