What to do if my Bosch Heat Pump is off on high pressure control?
- SShelley PriceAug 17, 2025
If your Bosch Heat Pump shuts off due to high pressure, it could be due to several reasons. In cooling mode, check for inadequate water flow, excessively warm entering water temperature, or a scaled or plugged condenser. In heating mode, ensure adequate airflow by checking for an inoperative blower, clogged filter, or restrictions in the ductwork. Also, the unit might be overcharged with refrigerant, so reclaim the excess, evacuate, and recharge it with the factory-recommended amount. Finally, inspect the high-pressure switch for defects or improper calibration.
