Bosch Error Code P1

If your Bosch air conditioner displays Error Code P1, it generally indicates high pressure protection. This happens when the system detects refrigerant pressure above safe levels, often caused by dirty coils, restricted airflow, fan failure, overcharge, or internal blockages.

Symptoms include poor cooling, sudden shutdown, and difficulty restarting. High pressure faults can strain the compressor and shorten system lifespan if repeated.

The solution often involves cleaning and restoring outdoor airflow, checking fan operation, and verifying refrigerant performance — but it requires proper testing to avoid incorrect adjustments.
