Setup

3. Placement: Place the yoghurt maker on a clean, dry, stable, and heat-resistant surface, away from direct sunlight or heat sources.

Operating Instructions

Follow these steps to prepare homemade yoghurt:

1. Prepare the Yoghurt Mixture:
   • Heat 1 liter of milk (full-fat, semi-skimmed, or skimmed) to approximately 45-50°C. This temperature is crucial for activating the yoghurt cultures.
   • Allow the milk to cool to about 40-45°C. It should be warm to the touch but not hot.
   • Add 2-3 tablespoons of plain, natural yoghurt with live cultures (as a starter) or a packet of commercial yoghurt starter culture to the cooled milk. Stir well until fully combined. Ensure the starter yoghurt has the same fat content as the milk for best results.
   • Optional: Add sugar or other flavorings at this stage if desired.
2. Fill the Jars: Pour the prepared yoghurt mixture evenly into the seven clean glass jars. Do not overfill.
3. Place Jars in Unit: Place the filled, open glass jars into the yoghurt maker unit.
4. Cover: Place the transparent lid securely onto the yoghurt maker unit.
5. Connect to Power: Plug the appliance into a suitable 230 Volt power outlet.
6. Start Fermentation: Press the illuminated On/Off switch to turn on the appliance. The indicator light will illuminate, signifying that the heating process has begun.
7. Fermentation Time: Allow the yoghurt to ferment for approximately 8-9 hours. The exact time may vary depending on the desired consistency and ambient temperature. Longer fermentation generally results in a thicker and tangier yoghurt.
8. Switch Off: Once the desired consistency is achieved, press the On/Off switch to turn off the appliance. Unplug the appliance from the power outlet.
9. Cool and Store: Remove the glass jars from the yoghurt maker. Screw on their lids. Allow the yoghurt to cool completely at room temperature before refrigerating. Store the finished yoghurt in the refrigerator for up to one week.

Maintenance and Cleaning

Regular cleaning ensures the longevity and hygiene of your yoghurt maker.

• Before Cleaning: Always unplug the appliance from the power outlet and allow it to cool completely before cleaning.
• Main Unit: Wipe the exterior of the main unit with a soft, damp cloth. Do not use abrasive cleaners or scourers. Never immerse the main unit in water or any other liquid.
• Glass Jars and Lids: The glass jars and their screw lids, as well as the transparent lid, are dishwasher safe. Alternatively, they can be washed by hand in warm soapy water, rinsed thoroughly, and dried completely before storage or next use.
• Storage: Store the clean and dry appliance in a cool, dry place.

Troubleshooting

If you encounter issues with your yoghurt maker, consider the following common solutions:

• Yoghurt is too watery or not setting:
  • Ensure the milk was heated to the correct temperature (45-50°C) and cooled to the correct temperature (40-45°C) before adding the starter.
  • Verify that the starter yoghurt contains live, active cultures. Using old or inactive starter yoghurt will prevent proper fermentation.
  • Increase the fermentation time. Some recipes or desired consistencies may require longer than 8-9 hours.
  • Ensure the milk and starter yoghurt have similar fat content.
  • Avoid disturbing the yoghurt maker during the fermentation process.
• Yoghurt is too sour:
  • Reduce the fermentation time.
  • Ensure the ambient temperature is not excessively high.
• Appliance does not turn on:
  • Check if the power cord is securely plugged into both the appliance and the wall outlet.
  • Ensure the wall outlet is functioning correctly by testing it with another appliance.
  • Verify that the On/Off switch is pressed.

If problems persist, contact customer support or a qualified technician.
