Bosch Dryer Error Code E:22

E:22 on a Bosch dryer means the main control module has detected an invalid software or firmware update condition. The dryer immediately stops all operation and cannot be restarted through any user input. Resolving this error requires replacing the faulty control module, as there is no user-accessible reset or reprogramming procedure for this fault.

The dryer will not operate at all when E:22 is active, so there is no immediate safety risk from the appliance running. However, you should not attempt to bypass or override the lockout, as the control board's inability to execute valid programming means safe operation of the motor, heating element, and sensors cannot be guaranteed.

A knowledgeable DIYer with experience in appliance repair can replace the control module, provided they source a compatible board for their specific dryer model. The replacement board must match the model to avoid introducing a firmware incompatibility that could itself trigger E:22. If you are not comfortable working with appliance electronics, a qualified technician is the safer choice.

No, a standard reset by unplugging the dryer or pressing the power button will not clear E:22. The error is caused by an invalid firmware state stored within the control module itself, which persists through power cycles. The only resolution is to replace the control board.

The cost to repair E:22 depends primarily on the price of a compatible replacement control module and labor if you hire a technician. Control board replacement parts for Bosch dryers typically range from $150 to $350 depending on the specific model. Adding professional labor, total repair costs generally fall between $250 and $550.
