6. Troubleshooting
If you encounter issues with your COOKLEE Stand Mixer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Mixer does not start. | Not plugged in; power outlet not working; speed dial not set. | Ensure the mixer is securely plugged in. Test the outlet with another appliance. Turn the speed dial to a setting other than '0'. |
| Attachments do not reach ingredients at the bottom of the bowl. | Attachment not fully engaged; bowl not properly seated. | Ensure the attachment is pushed up and rotated until it clicks into place. Verify the mixing bowl is locked onto the base. |
| Mixer is vibrating excessively or moving on the countertop. | Unstable surface; non-slip suckers not engaged; too much load. | Place the mixer on a flat, stable surface. Ensure the non-slip suckers are clean and making good contact. Reduce the amount of ingredients if exceeding capacity. |
| Loud noise during operation. | Normal operation for heavy loads; attachment not properly installed. | Some noise is normal, especially with dense doughs. Check that attachments are correctly installed. If noise is unusual or excessive, contact support. |
