Quick Check Before Troubleshooting
- Make sure the power cord is connected securely.
- Confirm the glass container or jars are not overloaded.
- Use clean, sterilized food-contact parts before each batch.
- Do not disturb the appliance during fermentation.
- Refrigerate the finished yogurt before judging final thickness.
- For regular yogurt, start with the Yogurt program. For Greek yogurt, remember straining is required after fermentation.
Best-Practice Setup for Better Yogurt
- Regular Yogurt: Use the Yogurt program, about 104°F / 40°C, with a default time around 8 hours.
- Greek Yogurt: Use the Greek Yogurt program, about 10 hours, then strain to remove whey.
- Milk: Whole milk usually gives a thicker, creamier result than low-fat or skim milk.
- Starter: Use fresh starter culture, about 5g starter powder or about 4 tablespoons of plain yogurt.
- Milk temperature: Keep milk cold or below 104°F / 40°C before fermentation.
- Time adjustment: Longer fermentation can increase both thickness and sourness.
Common Problems
Use the sections below to find the issue closest to your situation.
Why does the display not light up?
If the display does not turn on, the most likely cause is a power supply problem.
Possible causes
- The plug is not fully connected.
- The outlet is not working.
- The unit is not receiving power.
What to do
- Check the socket and make sure it is working.
- Reconnect the power cord securely.
- Try another outlet if needed.
- If the socket works and the unit still does not light up, contact service support.
Why is the temperature not rising?
If the appliance powers on but does not seem to warm properly, there may be an internal heating issue.
Possible cause
- The heating element may not be working correctly.
What to do
- Stop using the appliance temporarily.
- Do not attempt to disassemble the base unit.
- Contact service support for inspection.
Why is my yogurt runny or watery?
Short answer: Yogurt is usually runny because fermentation time is too short, the milk is too lean, the starter culture is weak, or the batch was judged before chilling.
Common causes
- Fermentation time was too short.
- Low-fat or skim milk was used instead of whole milk.
- Starter culture was weak, old, or not enough.
- Milk temperature was too high or too low before fermentation.
- The yogurt was checked before cooling in the refrigerator.
What to do
- Use the regular Yogurt program first for standard yogurt.
- Extend fermentation gradually to about 10–12 hours if you prefer thicker yogurt.
- Use whole milk for a richer texture.
- Use fresh starter culture: about 5g starter powder or about 4 tablespoons of plain yogurt.
- Keep milk below 104°F / 40°C before starting the cycle.
- Refrigerate the finished yogurt before judging final thickness.
Why didn’t my yogurt set properly?
If the batch remains loose or fails to form a proper yogurt texture, the issue is usually related to starter strength, milk condition, temperature, or cycle time.
Possible causes
- The starter culture was inactive or too weak.
- The milk was too hot or too cold at the start.
- The fermentation cycle was interrupted.
- The ingredient ratio was not ideal.
- The machine was disturbed during fermentation.
What to do
- Use fresh starter culture.
- Use whole milk or another milk known to ferment well.
- Keep milk below 104°F / 40°C before starting.
- Avoid opening or moving the machine during the cycle.
- Try a slightly longer fermentation time on the next batch.
How can I make my yogurt thicker?
If you want thicker yogurt, the most effective changes are better milk, enough starter, longer fermentation, and chilling before serving.
Best methods
- Use whole milk instead of low-fat milk.
- Extend fermentation to about 10–12 hours.
- Use fresh, active starter culture.
- Chill the yogurt fully after fermentation.
- For Greek-style yogurt, strain out some whey after fermentation.
Why is my yogurt too sour or over-fermented?
Over-fermented yogurt usually means the cycle ran too long for your preferred taste, or the ingredients and room conditions accelerated fermentation.
Possible causes
- The fermentation time was too long.
- The room environment caused faster fermentation.
- The batch was left too long before chilling.
What to do
- Shorten the fermentation time on the next batch.
- Record the time and taste you prefer for future batches.
- Chill the yogurt as soon as it reaches the flavor you want.
Why is there liquid on top of my yogurt?
A small amount of liquid on top is normal. This liquid is whey, which is a natural part of yogurt.
What you can do
- Stir it back in for a smoother texture.
- Pour some off if you want a thicker result.
- Strain the yogurt for a Greek-style texture.
Why did the jars overflow, or why did the lids lift off?
If the inner surface becomes dirty with fermented product, or the lid is pushed open, the jars may have been overfilled or the cycle may have run too long.
Possible causes
- The jars were overloaded.
- The fermentation time was too long.
- The volume increased during fermentation more than expected.
What to do
- Do not fill containers too close to the top.
- Leave extra room because volume can increase during fermentation.
- Reduce or better control fermentation time.
- Keep notes to find the best working method for your ingredients.
Why did the display reset or stop before fermentation was finished?
If the display shows reset settings before the process is complete, a power interruption may have occurred during the cycle.
Possible cause
- The unit briefly lost power during fermentation.
What to do
- Check whether the ingredients are still fresh and safe.
- If the batch may no longer be safe, discard it.
- Reconnect the appliance and restart only if appropriate.
- Use a stable power source for future batches.
Should I use Yogurt mode or Greek Yogurt mode?
Use Yogurt mode if you want regular yogurt that does not need straining. Use Greek Yogurt mode if you want a thicker result and plan to strain whey after fermentation.
- Yogurt mode: regular yogurt, default around 8 hours
- Greek Yogurt mode: thicker style, around 10 hours plus straining
How do I clean up after overflow or spills?
If yogurt or other ingredients spill inside the appliance, unplug it first and let it cool down before cleaning.
- Never immerse the base unit, power cord, or plug in water.
- Wipe the base unit with a damp cloth only.
- Wash removable parts separately.
- Dry all parts fully before the next use.
