5. Operating Instructions
5.1 Filling Milk
Pour cold milk into the frother jug. Observe the internal MAX and MIN level indicators:
- MAX (Heating Milk): Do not exceed 300ml (10 oz) when only heating milk (using the heating whisk).
- MAX (Milk Frothing): Do not exceed 150ml (5 oz) when frothing milk (using the frothing whisk).

Exceeding the MAX frothing level can cause overflow during operation.

6. Maintenance and Cleaning
Proper cleaning ensures the longevity and hygiene of your frother.
- Always unplug the appliance from the power outlet before cleaning.
- Hand Wash Only: The frother jug is not dishwasher safe and should not be submerged in water.
- Interior Cleaning: Immediately after each use, rinse the interior of the frother with warm water. Use a soft, non-abrasive sponge or cloth with mild dish soap to clean the non-stick interior. Ensure all milk residue is removed, especially around the drive shaft and whisk.
- Whisk Cleaning: Remove the whisk(s) and wash them with warm soapy water. Rinse and dry thoroughly.
- Exterior Cleaning: Wipe the exterior of the frother and the power base with a damp cloth. Do not use abrasive cleaners or scouring pads.
- Drying: Ensure all parts are completely dry before reassembling or storing the frother.
7. Troubleshooting
If you encounter issues with your Longdeem Electric Milk Frother, refer to the following common problems and solutions:
- Frother does not turn on: Ensure the power base is securely plugged into a working outlet and the frother jug is correctly placed on the base.
- Milk is not frothing or frothing poorly:
- Ensure the correct frothing whisk is installed.
- Check that the milk level is between the MIN and MAX frothing indicators (75ml - 150ml).
- Use cold, fresh milk. Whole milk generally produces the best froth.
- Ensure the whisk is clean and free of obstructions.
- Milk is not heating:
- Ensure the heating whisk is installed if you only want to heat milk without frothing.
- Check that the milk level is between the MIN and MAX heating indicators (75ml - 300ml).
- The frother has no adjustable temperature control; it heats to an optimal temperature for beverages.
- Milk overflows during operation: The milk level likely exceeded the MAX frothing indicator (150ml). Reduce the amount of milk.
- Unusual noise during operation: Ensure the whisk is properly seated on the drive shaft and there are no foreign objects in the jug.
- Base instability: Ensure the power cord is routed correctly from the base to prevent tilting.
If the problem persists after attempting these solutions, please contact customer support.
