Keep the area around the appliance clear

Do not cover the heater or block access to valves, pipes, electrical connections, or service points. Check periodically for visible leaks, unusual noise, corrosion, or damaged cables.

Use qualified service support

Internal inspection, electrical work, pressure-relief device checks, descaling, and component replacement should be handled by a qualified technician. Disconnect the electrical supply before service and follow local safety requirements.

Water conditions matter

Mineral buildup varies by water quality and usage. A technician can recommend an appropriate inspection interval for the tank, heating element, safety components, and sacrificial anode where fitted.

Follow the instructions for the exact model

Specifications and service requirements can vary. Keep the model information available and follow the product manual instead of applying a single maintenance schedule to every installation.
