5. Examine Sensors and Thermostats

   Faulty sensors can lead to incorrect readings and resultant error codes. Test each sensor for functionality and replace if malfunctioning.

6. Check Drainage System

   Clogged drain lines or pumps can cause water build-up and trigger errors. Clear any obstructions and ensure proper drainage for optimal performance.

7. Review Recent Changes

   Evaluate any recent adjustments or external factors that could contribute to errors, such as changes in environmental conditions, recent installations, or upgrades.

8. Consult the Daikin Error Code Reference
