Bosch Dryer Error Code E:23

E:23 on a Bosch dryer means the control module cannot match its stored model variant data to the dryer's configuration table. This mismatch causes the dryer to stop completely and prevents it from being restarted. The fault points directly to the control module as the component that needs to be addressed. It is not a sensor or mechanical fault, but a software or hardware configuration issue within the module itself.

The prescribed fix for E:23 is replacement of the control module. The replacement module must be the correct variant for your specific Bosch dryer model. If the error appeared after a previous module replacement, the installed module may have been intended for a different model variant and should be replaced with the properly matched part.

Repair costs for E:23 will depend on the price of the replacement control module and whether you hire a technician or replace the part yourself. Control module replacement on Bosch dryers typically falls in the range of $150 to $400 or more when including parts and professional labor, though costs can vary by region and specific model. DIY replacement can reduce costs significantly if you are comfortable working with appliance electronics.

No, a standard power reset will not clear E:23. Because the fault is caused by a model variant mismatch embedded within the control module's firmware or hardware, cycling power does not resolve the underlying conflict. The dryer will remain locked out and unable to restart until the control module is replaced with a correctly matched unit.

When E:23 is active, the dryer shuts down and cannot be restarted, so continued use is not possible without resolving the fault. The dryer's control system treats this as a critical error and enforces a full lockout as a precaution. Do not attempt to bypass or override the lockout, as the control module may not be able to safely govern the dryer's operation in this state.
