If your Slush 'n' Whip is making a knocking noise, this may be caused by frozen mix getting caught on the barrel.
- Check that your mix contains enough sugar.
- Insufficient sugar can cause the mix to freeze incorrectly and catch on the barrel.
- Check your recipe or mix instructions and ensure the correct amount of sugar has been used.
If the knocking continues after checking the mix, please contact our Customer Service team for further assistance.
