     • If digital, check for software updates or recalibration options.
     • Double-check user inputs for any possible error.

🌡️ Humidity and Moisture Signals

1. E30: Excess Moisture Warning

   • Cause: The interior moisture level is too high, hindering efficiency.
   • Solution:
     • Check for leakage or improper sealing within the chamber.
     • Ensure optimal space between items to allow air circulation.
     • Increase the runtime for particularly moist foods.

2. E31: Low Humidity Detection

   • Cause: Low moisture levels can signal that dehydration is overly aggressive.
   • Solution:
     • Shorten drying time for sensitive ingredients.
     • Adjust temperature settings downward.
     • Layer thicker food pieces to slow down dehydration.

⚙️ Maintenance and Component Alerts

1. E40: Filter Clog Detection

   • Cause: Air filters are clogged, hindering air flow and efficiency.
   • Solution:
     • Regularly clean or replace air filters as advised by the manual.
     • Ensure air intakes are not obstructed by external objects.

2. E41: Motor Dysfunction

   • Cause: The motor has encountered a running issue.
   • Solution:
     • Turn off? Remove and inspect motor components.
     • Seek professional repairs if necessary, particularly for bearing-related issues.

3. E42: Heating Element Failure

   • Cause: Malfunction or failure of the heating element.
   • Solution:
     • Inspect the element for visible damage or burnouts.
     • Replacement may be required; consult with the manufacturer.

📏 Custom Error Codes
