Why does the 'change filter' symbol appear on my Aqua Optima Kitchen Appliance?
- Aamanda19Aug 3, 2025
The 'change filter' warning symbol illuminates on your Aqua Optima Kitchen Appliance after 100L because the filter life has expired. To resolve this, change the filter following the Aqua Optima filter instructions. After replacing the filter, reset the filter warning symbol by holding it for 3 seconds.
