How do I add essential oils?
✓ Steps 1 and 2
Load your dishwasher as normal and place Dishwashing Tab in the detergent compartment.
Add 1 to 2 drops of your chosen Koh essential oil directly onto the top surface of the tab.
✓ Steps 3 and 4
Close the compartment. Never pour oil into the dispenser or directly into the machine.
Run the cycle and enjoy a subtle scent.
What should I watch out for?
⚠ Keep it to 1 to 2 drops
Too much essential oil can leave residue on glassware or cutlery, and may cause issues with your machine over time. If you notice residue, streaking, or unwanted scent, reduce the amount or stop using oil.
✓ Which oils to use
For best results and compatibility, we recommend using Koh essential oils only. Used sparingly, essential oils shouldn't affect cleaning performance. Store oils safely away from children and pets.
