Descaling
Mineral deposits (limescale) can build up over time, affecting performance. Descale your dispenser regularly, especially in areas with hard water.
- Use a commercial descaling solution suitable for hot water dispensers, following the manufacturer's instructions.
- Alternatively, a solution of white vinegar and water (1:1 ratio) can be used.
- Run the descaling solution through the unit, then rinse by running several cycles of fresh water.
Filter Replacement
The water filter should be replaced according to the manufacturer's recommendations or if you notice a decrease in water quality or flow rate. Refer to the filter packaging for specific instructions.
