6. Maintenance
Regular maintenance ensures the efficiency and extends the lifespan of your Ariston Blu1 Eco water heater. Always disconnect the power supply before performing any maintenance.
- Anode Inspection: The magnesium anode is a consumable part that protects the tank from corrosion. It should be inspected and replaced by a qualified technician every 1-2 years, depending on water quality.
- Pressure Relief Valve Check: Manually operate the pressure relief valve at least once a year to ensure it is not blocked and functions correctly. Follow the manufacturer's instructions for this procedure.
- Descaling: In areas with hard water, limescale can build up on the heating element and inside the tank, reducing efficiency. Descaling should be performed periodically by a qualified technician.
- Draining the Tank: If the water heater will be out of use for an extended period or if there is a risk of freezing, the tank should be drained. Consult a professional for this procedure.
- External Cleaning: Clean the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
