The customer initially experienced no hot water from their storage water heater, followed by a power trip when the heater was switched on. Within its lifespan, the storage water heater had faced issues of no hot water and power tripping. These issues were likely caused by a faulty heating element or thermostat. During a site inspection, our licensed technician discovered a spoiled heating element. Further examination of the electrical connection revealed burn marks on the isolator, indicating a potential hazard. Although the existing isolator and wire sizing were correct, the problem stemmed from a loose wire connection. This loose connection posed a significant danger, including the risk of electrical fires, equipment damage, and potential harm to users. After the inspection, our Homeone team discussed the findings with the customer and proceeded to replace the rusty heating element and the burnt isolator with a new 20A isolator switch. This resolved the issues of no hot water and power tripping, ensuring compliance with LEW and PUB regulations for safety and reliability.

This heating element replacement and electrical work has met the following requirements for a storage water heater:
Begin by inspecting all wiring connected to the storage water heater, ensuring wires are 2.5mm in size, as required.
Then check the heater switch, magnetic contactor, and isolator to ensure the correct sizing and wire connection.
Check the heating element and thermostat for rust, and if none is found, conduct a light bulb test to determine if the fault lies in the connection or the heating element itself.
If the heating element is identified as faulty, it should be promptly replaced with a new one.
This step is crucial to restore the water heater’s functionality and ensure efficient heating performance.
Replace any faulty switches, isolators, and wires, especially if they show signs of wear, burn marks, or incorrect sizing.
This is vital for maintaining safety and preventing future electrical issues.
After replacements, thoroughly test the water heater system to ensure it operates correctly and safely.
Clean up the work area, leaving it tidy and free of debris, and provide the customer with a brief overview of the work completed.
The electric water heater as a whole unit (i.e. parts incorporated in the water heater itself such as heating element, pressure relief valve/temperature relief valve, water tank, etc. shall be tested in accordance with the following:
