To keep your SVEN KT-S1733W electric kettle working its best, how often you descale it depends on your water's hardness. The user manual provides these guidelines: If you have soft water (less than 18 dH), descale every three months. For hard water areas (over 18 dH), descale monthly. Regular descaling prevents mineral buildup, ensuring your kettle operates efficiently and lasts longer. Always follow the cleaning instructions in your SVEN KT-S1733W manual for the best results.
