What to do if Mitsubishi PUHZ-W85VHA2.UK Heat Pump trouble is not reoccurring but is logged?

If the Mitsubishi Heat Pump trouble is not reoccurring but is logged, it may be due to temporary defects like protection devices in the refrigerant circuit including the compressor, poor wiring connections, or noise. Re-check the symptom, installation environment, refrigerant amount, weather when the trouble occurred, and wiring. Also, reset check code logs and restart the unit after service. Note that there might be no abnormality in the electrical components or controller board.
