Bosch Refrigerator Error Code Co

The Co code on a Bosch refrigerator indicates the unit is in Display Full Down mode, which is a demo or showroom setting. In this state, the compressor and cooling system are turned off, though the display and interior lights remain active. The refrigerator will not cool food while this mode is active. Exiting demo mode through the control panel will restore normal cooling operation.

The Co code itself does not indicate a hazardous condition, but it does mean the refrigerator is not cooling. Food stored in the unit while Co is active will not be kept at a safe temperature, which can lead to spoilage. It is best to address the code promptly and avoid storing perishable food until cooling is confirmed to have resumed.

In most cases, resolving the Co code costs nothing because it involves deactivating demo mode through the control panel with no parts required. If the control board is preventing the unit from exiting demo mode correctly, board replacement could range from moderate to higher repair costs depending on parts and labor in your area. A service call for diagnosis alone can range from around $75 to $150 or more depending on your location and the technician.

The Co code is typically resolved by pressing a specific button combination on the control panel to deactivate Display Full Down mode. The exact sequence varies by model, so consulting your unit's user guide for the demo mode exit procedure is recommended. Once the mode is deactivated, the compressor should resume and the Co code should clear. If the code returns after performing the correct steps, the control board may need further inspection.

A simple power reset, such as unplugging the unit and plugging it back in, may not clear the Co code if the control board retains the demo mode setting after power is restored. The correct method is to exit Display Full Down mode using the designated control panel button sequence. If a power reset does clear the code, monitor the unit to ensure it does not re-enter demo mode on its own.
