Performing a Basic Reset
- Unplug the air fryer from the power outlet.
- Wait at least 5 minutes to allow internal components to reset.
- Reconnect the power cord securely.
- Turn on the air fryer and see if the error persists.
This simple reset can clear temporary glitches that cause error codes. Ensure the plug is firmly inserted and the outlet is functioning correctly.
Cleaning and Inspecting Components
- Remove the basket and any accessories, then clean them thoroughly with warm, soapy water. Dry completely.
- Check the heating element for any debris, grease, or food particles. Use a soft cloth or brush to gently clean it.
- Inspect the air intake and exhaust vents for dust or blockages. Clear any obstructions.
- Examine the power cord and plug for damage. Do not use if there are signs of wear or fraying.
A clean, unobstructed air fryer reduces the risk of overheating or sensor errors caused by dirt or debris.
Resetting Internal Sensors and Settings
If cleaning doesn’t resolve the error, try resetting internal sensors or settings. Some models allow you to do this by pressing and holding certain buttons or performing a specific sequence, which you can find in the user manual. If your model doesn’t have this feature, simply perform a power cycle as described above. This can recalibrate sensors and clear minor glitches.
When to Contact Support and Safety Tips
If error codes persist after these steps, it’s best to contact COSORI customer support. Provide the model number and a detailed description of the issue. Do not attempt to disassemble the unit further, as this can void warranty or cause safety hazards.
Always unplug the air fryer before inspecting or cleaning internal parts. Avoid using abrasive cleaners or metal tools that could damage components. Safety first!
