6. Maintenance
The Kalia Aspen radiator requires minimal maintenance.
- Cleaning: Ensure the radiator is switched off and unplugged from the power supply before cleaning. Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.

7. Troubleshooting
If you encounter issues with your radiator, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator not heating | No power supply; Incorrect mode/temperature setting; Overheat protection activated. | Check if the radiator is plugged in and the power outlet is functional. Verify circuit breaker. Ensure the desired mode is selected and the temperature is set above the current room temperature. If overheat protection is active, unplug, allow to cool, and check for obstructions. |
| LCD display not working | No power supply; Internal fault. | Check power supply. If power is present and the display remains off, contact customer support. |
| Radiator makes unusual noises | Normal expansion/contraction; Loose components. | Minor clicking or creaking sounds are normal as the metal heats and cools. If noises are loud or persistent, ensure the radiator is securely mounted. If the issue persists, contact support. |
| Open window detection activates frequently | Actual open window/door; Strong draft near the sensor. | Close windows/doors. Relocate the radiator if it's in a particularly drafty area, or temporarily disable the feature if available in settings. |
