Dryer Will Not Start
- Door not closed properly: Close the dryer door firmly until it latches. Check that clothing is not trapped in the door opening.
- Child Lock enabled: Disable Child Lock using the button combination shown on the control panel or in the model-specific manual.
- Delay Start selected: Check whether a delayed start timer has been set before assuming the dryer is not operating.
- No electrical power: Check the outlet, plug, power cord, household circuit breaker, and electrical supply.
- Cycle selection issue: Choose a drying program and press Start according to the instructions for your model.
Drying Takes Too Long
- Lint filter blocked: Clean the lint filter before every drying cycle and remove lint from the filter housing area.
- Condenser or heat exchanger dirty: Follow the model-specific cleaning instructions for the condenser, heat pump filter, or lower filter system.
- Load too large: Reduce load size and separate heavy towels, bedding, jeans, and lightweight clothing.
- Incorrect drying program: Select the proper cycle for the fabric type, load size, and desired dryness level.
- Cold room temperature: Heat pump dryers may take longer in unheated garages, basements, or low-temperature laundry rooms.
Heat Pump & Condensation Dryer Problems
- Water container full: Empty the condensate water tank if the dryer is not connected directly to a drain.
- Water tank warning stays on: Reinstall the tank fully and check that the float or sensor area is clean.
- Heat exchanger filter needs cleaning: Clean the lower filter or condenser filter according to the maintenance schedule in the manual.
- Room feels humid: Ensure filters are clean and confirm that the dryer has proper clearance and ventilation around the cabinet.
- Dryer feels cooler than expected: Heat pump models operate at lower temperatures and may need more time than conventional vented dryers.
Lint Filter & Airflow Problems
- Filter warning appears: Clean the lint filter carefully and remove buildup from the filter housing.
- Lint screen damaged: Replace damaged filters to prevent lint from entering the appliance interior.
- Filter seems clean but drying is slow: Wash the lint filter with warm water if residue from fabric softener or detergent has reduced airflow.
- Air channels blocked: Inspect the air intake and exhaust areas for lint, dust, or obstructions.
- Frequent warning messages: Clean all accessible filters and consult the specific manual for condenser or heat pump maintenance steps.
Common Bosch Dryer Error Code Symptoms
- Door error: Close the door firmly and inspect the latch, strike, and door switch area for lint or clothing obstruction.
- Temperature or sensor error: Allow the dryer to cool, clean filters, and inspect airflow before restarting.
- Water container alert: Empty and reinstall the condensate tank, then check the drainage system if the warning remains.
- Filter or airflow warning: Clean the lint filters, lower filters, and condenser-related components according to your manual.
- Control system error: Disconnect power for several minutes and consult the model-specific manual if the code returns.
Sensor Dry & Laundry Results
- Clothes remain damp: Choose a higher dryness level, reduce load size, and clean the filters and moisture sensing system.
- Dryer stops too early: Avoid mixing very small and very large garments in the same load, and select an appropriate program.
- Clothes overdry: Choose a lower dryness level and use the correct program for the fabric type.
- Wrinkles remain: Avoid overloading and remove garments promptly at the end of the cycle.
- Heavy items remain damp: Separate towels, jeans, bedding, and other thick fabrics from lightweight laundry.
Noise, Vibration & Maintenance Tips
- Thumping sound: Bulky laundry may create temporary thumping. Pause the dryer and redistribute the load if needed.
- Rattling: Check pockets for coins, keys, zippers, buttons, or other loose objects.
- Vibration: Adjust all dryer feet so the appliance is level and installed on a firm, even floor.
- Musty odor: Clean filters, the drum, and the condensate container. Avoid leaving damp laundry in the dryer after a cycle.
- Interior light not working: Check door closure, appliance settings, and the model-specific manual for service instructions.
Installation & Maintenance Tips
- Level the dryer: Adjust all feet so the appliance is stable and does not rock during operation.
- Allow clearance: Leave enough space around the dryer for ventilation and service access according to the installation manual.
- Direct drain connection: If using a drain hose, make sure it is installed correctly and not kinked or blocked.
- Clean filters regularly: Follow the maintenance schedule for lint filters, condenser filters, heat pump filters, and water containers.
Safety note: Always disconnect electrical power before cleaning internal areas, checking filters, replacing parts, or servicing the appliance. Do not operate the dryer with damaged filters, a blocked airflow system, or a defective door switch.
