4. Operation
The Bosch 11003806 Heat Exchanger Condenser operates as an integral component of your dryer's drying system. Its primary function is to condense moisture from the heated air, allowing it to be collected and drained, thus drying your laundry.
Once correctly installed, the condenser works automatically with your dryer's cycles. Ensure that the condenser is fully seated and secured in its compartment before operating the dryer. The "easy clean handle" feature is designed for convenient removal during maintenance, not for operational adjustments.

Regular cleaning of the heat exchanger condenser is essential for maintaining your dryer's efficiency and preventing issues. The Bosch 11003806 features an "easy clean handle" to facilitate this process.
- Frequency: Consult your dryer's main instruction manual for recommended cleaning intervals. Typically, condensers should be cleaned every few months, or more frequently if you notice reduced drying performance.
- Access:
- Ensure the dryer is unplugged from the power supply.
- Open the condenser access panel on your dryer.
- Removal:
- Grasp the "easy clean handle" on the condenser unit.
- Carefully pull the condenser straight out of its compartment.
- Cleaning:
- Rinse the condenser thoroughly under running water, preferably a shower head, to remove all lint and debris from between the fins.
- Ensure water flows freely through all channels.
- Do not use harsh chemicals or abrasive brushes, as these can damage the fins.

6. Troubleshooting

- Error Codes: Some dryers may display specific error codes related to the condenser or moisture removal system. Consult your dryer's main instruction manual for the meaning of these codes and recommended solutions.
- Water Leaks: Ensure the condenser is properly seated and secured in its compartment. Check the seals around the condenser for any damage.

If troubleshooting steps do not resolve the issue, or if you suspect a defect with the condenser itself, contact a qualified service professional or Bosch customer support.
