Troubleshooting
If you encounter any issues with your Chefman Obliterator Blender, refer to the following common problems and solutions:
Blender does not turn on:
- Ensure the power cord is securely plugged into a functional electrical outlet.
- Verify that the blending jar (either 48 oz or 20 oz travel jar with its blade assembly) is properly seated and locked onto the motor base. The control panel may display a "Fix Jar" alert if it's not.
Ingredients are not blending smoothly or blender seems to struggle:
- Ensure sufficient liquid is added to the ingredients. The control panel may display an "Add Liquid" alert.
- If blending thick mixtures, use the provided tamper tool to push ingredients towards the blades. Only use the tamper when the blender is off or on a low speed, and never with the 20 oz travel jar.
- Try using the Pulse function for short bursts to break down stubborn ingredients.
- Do not overload the blending jar beyond the MAX fill line.
Loud noise or burning smell during operation:
- Immediately unplug the blender from the power outlet.
- Check for any obstructions around the blade assembly.
- Do not continue to operate the blender if the motor sounds strained or if there is a burning smell. Contact Chefman customer support for assistance.
