It is recommended for self-installation with little experience: ⚠️ Disconnect the machine from the electricity and water. Before starting work ⚠️ Place a towel on the floor – some water may spill. Move the machine forward to gain access to the back. Locate the drain hose – it is connected to the pump and comes out the back of the machine. Loosen the clamping clip on the part connected to the pump. Gently pull out the old pipe. Connect the new hose – make sure the clip is seated in its intended groove. Insert the outer end into the drain at least 60 cm above the floor. Run a short drainage program to check for leaks. �� Tip from the experts �� Tip from the experts: When you replace the drain hose, take the opportunity to clean the pump filter as well. The filter is located on the bottom panel of the machine. Cleaning it once a month prevents future blockages and extends the life of the pump. ❓ Frequently Asked Questions What is the difference between error code E18 and a pump problem? The E18 code indicates a drain failure – but the cause could be the hose, the filter, or the pump itself. Therefore, before ordering any parts, first check the pump filter. If the filter is clean and the hose is in good condition and there is no visible deformation – the pump itself may be faulty and requires a technician’s inspection. Can the drain hose be extended with an extension? Yes, BSH sells original drain hose extension kits. However, it is important not to extend beyond the manufacturer's recommended length. Excessive extension reduces drain pressure and may cause partial drainage. Always ensure that the height of the drain hose is at least 60 cm and no more than 100 cm. Does replacing a drain hose void the appliance warranty? No, as long as an original BSH part is used. EU regulations protect the consumer and allow independent replacement of parts with original parts. However, using a non-original part that has caused damage may void the warranty.
