When your Bosch dryer starts acting up, the first thing you should do is check if it’s displaying any error codes on its screen. These codes are a way for your appliance to communicate specifically what’s going wrong with its system, allowing you to identify and, in many cases, solve the problem without immediately calling a technician.
But what does each code mean? Below, we present a detailed table with the most common error codes for Bosch dryers, their description, the probable cause, and the suggested solutions. Before proceeding, it’s important to clarify some terms you might encounter:
- Lint filter: A mesh that traps lint and small debris from clothes during drying. It should be cleaned regularly to prevent blockages.
- Flexible exhaust hose: The duct through which hot, moist air exits the dryer to the outside.
- Heating element: The part of the dryer that generates heat to dry clothes.
- Wiring harness: A set of wires that transmit electrical signals and power between the dryer’s components.
- Control module: The “brain” of the dryer, an electronic board that manages all its functions.
