6. Maintenance
6.1 Cleaning
After each use, allow the probe to cool. Clean the metal probe tip and the lower part of the handle with warm, soapy water and a soft cloth. Rinse thoroughly and dry completely. Do not use abrasive cleaners or scourers. Do not immerse the entire sensor or charging station in water.
6.2 Storage
Store the sensor in its charging station in a dry, cool place when not in use. Ensure the sensor is clean and dry before storage.
7. Troubleshooting
- Sensor not connecting to appliance/app:
Ensure Bluetooth is enabled on your appliance and mobile device. Verify the sensor is within range and fully charged. Check the Home Connect app for any connection errors or updates. Restart both the sensor (if applicable) and your appliance/mobile device. - Inaccurate temperature readings:
Confirm the probe is inserted correctly into the thickest part of the food, avoiding bone, and past the minimum insertion line. Ensure the probe is clean and free from food residue that might affect readings. - Sensor not charging:
Check that the USB cable is securely connected to both the charging station and the power source. Ensure the power source is active. Verify the sensor is correctly seated in the charging station.
