- Remove Items: Carefully lift the cleaning basket out of the tank. Rinse the cleaned items with clean water and dry them thoroughly.
- Power Off: Turn off the heating and ultrasonic functions, then unplug the unit from the power outlet.
Note: For optimal cleaning, use a suitable ultrasonic cleaning solution. Tap water alone may not be sufficient for all cleaning tasks.
6. Maintenance
- Draining: After each use, or when the cleaning solution becomes visibly dirty, drain the tank using the drain valve.
- Cleaning the Tank: Wipe the inside of the tank with a soft cloth. Do not use abrasive cleaners or steel wool. For stubborn residue, a mild detergent can be used. Rinse thoroughly.
- Exterior Cleaning: Wipe the exterior of the unit with a damp cloth. Avoid getting water into the control panel or electrical components.
- Storage: Store the unit in a clean, dry place when not in use.
- Descaling (Periodically): If hard water is used, mineral deposits may accumulate. Descale the tank periodically using a mild descaling solution designed for stainless steel, following the solution's instructions.
