5. Cleaning and Maintenance
Regular cleaning and proper maintenance will ensure the longevity and efficient operation of your immersion heater.
- Before Cleaning: Always unplug the appliance and allow it to cool down completely before cleaning.

Submerge only the heating element in the descaling solution, ensuring the handle and electrical components remain dry. Rinse thoroughly with clean water after descaling.
- Cleaning the Handle and Cord: Wipe the heat-insulated handle and power cord with a damp cloth. Do not use abrasive cleaners or immerse these parts in water.
- Storage: Once completely dry, store the immersion heater in its protective case in a dry, safe place, away from children.
