- Completion: The unit will automatically stop when the set time expires.
- Power Off: Turn the main power switch to "OFF" and unplug the unit from the power outlet.
- Remove Items: Carefully remove the basket with the cleaned items. Rinse items with clean water if necessary and dry them thoroughly.
