The WTL5400 model uses condensation drying, which allows for vent-free operation, providing flexibility in installation locations where traditional venting is not possible.

Sensor Controlled Auto Cycles

Equipped with auto cycles that use sensors to determine six different drying levels, these dryers offer precise and efficient drying tailored to various fabric types.

Lint Filter Maintenance

The lint filter should be cleaned after each use to maintain efficient operation and reduce fire risk. A lint filter cleaning indicator is included for user convenience.

Additional Functions

Additional functions, such as the 'DELICATES' button, allow users to reduce drying temperature for heat-sensitive fabrics, providing care for delicate clothing items.

Maintenance

Check out our tips to prevent many common issues and extend the life of your Bosch Dryer.

Regular Lint Filter Cleaning

Clean the lint filter after every use to ensure efficient operation and energy saving. This prevents lint build-up which can lead to longer drying times and potential safety hazards.

Check Exhaust Vent and Air Inlets

Ensure that the exhaust vent for WTA models and air inlets for WTL models are not blocked. Blocked vents can cause the dryer to overheat and reduce efficiency.

Clean the Moisture Sensors

Regularly clean the moisture sensors located inside the drum to ensure accurate drying cycles. This prevents the dryer from running longer than necessary.

Heat Exchanger Maintenance (WTL Models)

Clean the heat exchanger 3-4 times a year, more often if the dryer is used frequently. This maintains the dryer's efficiency and prevents overheating.

Proper Loading

Do not overload the dryer. Follow the recommended load sizes to ensure optimal drying and prevent unnecessary strain on the appliance.
