Cleaning and Maintenance
Regular cleaning ensures the longevity and hygiene of your milk frother. The non-stick interior coating makes cleaning easy.
- Unplug: Always unplug the appliance from the power outlet before cleaning.
- Cool Down: Allow the frother to cool down completely after use.
- Clean Interior: The interior of the frother can be cleaned with a soft, damp cloth. For thorough rinsing, add approximately 150 ml of water, heat it briefly (without frothing), and then stir to rinse. Discard the water and wipe dry.

- Important: Never immerse the main unit or its electrical base in water or any other liquid. This will damage the internal circuitry. The frother is not dishwasher safe.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Frother does not turn on. | Not plugged in; power outage; appliance malfunction. | Ensure the frother is securely plugged into a working outlet. Check your circuit breaker. If the issue persists, contact customer support. |
| Milk is not frothing or heating properly. | Incorrect whisk; insufficient or excessive milk; type of milk; whisk not properly secured. | Ensure the correct whisk is used for the desired function. Check milk levels against MAX/MIN markings. Use fresh, cold whole milk (fat content > 3%) for best frothing. Ensure the whisk is firmly attached to the bottom of the jug. |
| Whisk detaches when pouring. | Whisk not properly secured. | Before each use, ensure the whisk is firmly pressed onto its spindle at the bottom of the frother jug. |
| Milk overflows. | Too much milk added. | Do not exceed the MAX fill lines for frothing (150ml) or heating (300ml). Milk expands when heated and frothed. |
