Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Appliance does not turn on. | Not plugged in; power outage; faulty outlet. | Check power cord connection; check circuit breaker; try a different outlet. |
| Milk is not frothing properly. | Incorrect milk type; insufficient milk quantity; stirring arm not correctly placed. | Use fresh, cold milk (full-fat milk generally froths best); ensure milk is between MIN/MAX lines; check stirring arm placement. |
| Chocolate pieces are not melting completely. | Too large chocolate pieces; too much chocolate; chocolate cage not properly installed. | Break chocolate into smaller pieces; do not overfill the chocolate cage; ensure cage is correctly attached to the stirring arm. |
| Appliance stops unexpectedly. | Overheating protection activated; program completed. | Allow appliance to cool down before restarting; this is normal operation if the program has finished. |
If the problem persists after trying these solutions, please contact WMF customer support.
